Once the materials and seeds are bought, it's time to get started.

Li Mo first asked everyone to plough the vegetable fields and expose them to the sun for three or four days, then apply a large amount of farm fertilizer, use a rake to level it, and buy rotten straw or wheat straw from other villagers. However, it is used in large quantities, such as Cao Zhen, a large acre, an acre of land often has to use nearly 3,000 catties, their own must be insufficient, insufficient, so I have to take money to buy from other people.

This is easy, no ticket is required, the four villages in Tangwan are insufficient, and there are other villages.

First, sprinkle manure and cake fertilizer, then chop these straw and wheat straw, sprinkle them in the ploughed vegetable field, and then sprinkle sixty or seventy catties of quicklime on one acre of land.

Then sprinkle water, cover with small arches, then cover with large arches, and cover with straw curtains.

Everyone was puzzled together, and Director Zhang asked: "Doesn't quicklime burn fields?"

"Quicklime is not to burn fields, it is to burn crops, but now there is no transfer, and when it is transferred, various chemical reactions have already occurred, and it is not quicklime. ”

Li Mo explained its role by the way.

This is called quicklime disinfection.

Of course, you can't use it indiscriminately, you have to use the PH test strip bought from Stone Town to test the pH of the soil. The overall topography of Tangwan is relatively low-lying, and it is a polder, and most of the chemical fertilizers used in the past are nitrogen fertilizers, so the soil is acidic.

However, just in case, it will be safer to check it with a test strip, and acidic soils can use this method. If it is alkaline soil, then this method must not be used.

One is to improve the pH of the soil, and the other is to disinfection.

After these broken grass straws are stained with water, they will further accelerate their decay, and they will be covered with two houses of arches, and with straw curtains, sealed and insulated, the grass straw will rot quickly, and the decaying process will release high temperatures. Coupled with the effect of quicklime, it can quickly kill all kinds of germs and nematodes in the soil.

In fact, Li Mo's method is not standard, the accurate method is June, July, July and August, that is, the hottest time of the year, apply enough rotten organic fertilizer and cake fertilizer, level the ground and rake finely, and then sprinkle grass straw quicklime, turn the ground, algae water, spread film, and close the greenhouse for half a month, which can basically kill all kinds of germs and nematodes.

But missing this hot time, Li Mo had to make some improvements, and after two days, he ran in and measured the surface temperature and the underground temperature with the temperature, and asked everyone to send it into the brazier to forcibly raise the temperature in the greenhouse.

When the brazier enters, one thing must be careful, not carbon dioxide, but carbon monoxide, so before people go in, they must open the shed door for a period of time, and wait for the outside air to circulate in, and then people can enter.

The third effect is that the rotting of grass straw will produce some organic matter, which will also make the soil softer.

Director Zhang had studied chemistry books, but he didn't know how to use them, and after hearing this, he muttered: "So that's the case." ”

"Uncle Zhang, although the commune has allocated a loan, but it has to be repaid, these costs are not small numbers for nine households, how dare I come nonsense? All fertilizers are almost ready, and there is no need to worry about the output. I am worried about all kinds of vegetable plague caused by germs, and the other is all kinds of pests, the former is more terrible than the latter, and some vegetable plague is detected and cannot be saved. If that's the case, how can I explain to my parents and to a few villagers. Therefore, although it is a little troublesome, all uncertainties must be nipped in the bud. ”

This is just the first step in disinfection.

Before the transfer, disinfect with chemicals, seal the shed for five or six days, and then transfer the vegetable seedlings, and the possibility of vegetable blast will decline indefinitely. There are also poisonous soil disinfection methods and fumigation disinfection methods, these two methods are more troublesome, and they are also aimed at the accumulated sheds, so Li Mo did not adopt them.

In addition, it is rotation, now all kinds of backward, backward technology, backward fertilizers, backward pesticides, and because of the heavy use of chemical fertilizers and pesticides, two or three years of planting, will produce pesticide damage and fertilizer damage, and will lead to a sharp reduction in yield.

The safest way is to plant vegetables in greenhouses for one year, which must rest for two years, and within two years after the absorption of crops, the pesticide damage and fertilizer damage will disappear completely, and because the bottom of the field keeps up, the crop harvest will increase.

Li Mo didn't hide it either, he said it in front of Director Zhang and several families.

After listening to it together, it is no wonder that Li Mo wanted to change fields at the beginning.

The people of the four villages began to be busy changing fields again, and the originally ordinary high-pitched fields suddenly became a hot commodity.

But this is a polder area, there is no shortage of water, and other places are different, the height of the fields is not a benefit, and the drought is coming.

At the same time as ploughing and raking the fields, the seedling fields also began at the same time.

There are two kinds of greenhouse vegetables, and each sowing time is different, of course, the difference between north and south will also cause a time gap.

Generally, like the middle and lower reaches of the river, the midwinter greenhouse is sown in mid-July of the solar calendar, and the harvest period is from late November to February. Or sow in late July, and harvest in late December and April. This is extremely costly, and it also has extremely high requirements for seeds, which is simply not possible at the moment.

In early spring, the sowing time is generally from mid-September to the end of December.

As for the harvest period, there will be no difference of three or four months, because in winter, the growth of vegetable seedlings will become very slow. The later it is, the smaller the cost and the less risky it is, but it is only thirty or forty days different from the normal market vegetables.

Well, one night later, when the time comes, sell it for a few pennies a pound.

Li Mo will definitely not choose to raise seedlings very late.

The earlier the maturity period, the earlier the seedling stage, if the seedlings are raised from the middle of September, and the vegetables can be marketed at the end of February, at least eighty or ninety days apart from the normal vegetable market time. Even after more than 80 days, the vegetables are cheap, and the vegetables in the greenhouse have come to an end, and the impact is not great.

This is a benefit, but the earlier it is, the higher the cost, and the more difficult it will be.

Now that the seedlings have been postponed for more than 20 days, it means that the market can be sold at night for 10 days, and the conflict with the normal vegetable market will be longer, and the income will inevitably be lost.

Start by beating a nutrient bowl in the seedling field.

In his previous life, when Li Mo first came into contact with the nutrient bowl, it was Li Guangping who wanted to grow hybrid watermelons. This paper bag is so troublesome that the family didn't adopt it.

Later, many people in Liuyewei planted cotton, and someone brought a tool, an iron cylinder similar to a piston, pressed it on the nutrient mud, and then lifted it up, and a long cylindrical nutrient bowl came out. Then the germinated cotton seeds are planted on it, there are several functions, effective use of fertilizer, cotton seedlings will be healthier, after transplanting in the field, fibrous roots to the periphery can not absorb nutrients, the plant will spontaneously let the taproot continue to grow downward. When the main root is deep, it will undoubtedly absorb more nutrients after it grows, and if the roots are strong and deep, there will undoubtedly be more harvests.

It is not only suitable for watermelon and cotton, including all fruits and vegetables with taproot, but without taproot, such as rice and wheat, this method can not be applied, and it cannot be played like this, they need so many seeds, if they raise seedlings like this, they must not exhaust people to death?

Nutrient mud is made from fertile silt mixed with various fertilizers, including fermented manure, cake fertilizer, and plant ash, with some chemical fertilizers.

If it weren't for Li Mo's teaching, no one would even ferment these farm fertilizers, manure could only be regarded as semi-fermented, and cake fertilizer didn't know about fermentation before, so okay?

And in the absence of compound fertilizer, more cake fertilizer must be applied instead.

Don't underestimate this procedure, if it weren't for Li Mo's promotion, it wouldn't be until more than ten years later, where in County A would someone use a nutrient bowl to raise vegetable seedlings.

Later, more people paid attention to it, and a plastic nutrition bowl appeared.

Of course, by that time, technology had also become more developed.

After the nutrient bowl is laid, the seedlings are transferred to the nutrient bowl and placed in the seedling shed. Because it is a winter vegetable seedling, it is necessary to refine the seedlings before planting in the field.

It's also troublesome to get off the field.

The first is that the shed must be sturdy, otherwise a heavy snowfall will collapse the shed and all the vegetables will be destroyed. Now it is not possible to use steel sheds, but it is necessary to use a lot of coarse bamboo to make canopy posts, and then put bamboo bows on both sides.

Therefore, the cost in the first year is amazing, not only the cost of the film, but also the cost of these bamboo materials.

The second is fertilizer, such as Cao Zhen, a large mu, before planting must apply more than 10,000 catties of fermented farm fertilizer, which is obviously impossible. It can only be said that those who are willing to give a little more, and those who are not willing to give a little less.

There are also various films, large arch films, small arch films, apron films, after mid-March, when the temperature rises, it is necessary to prepare shade nets.

In the severe winter, two layers of film and apron film are not enough, but also to cover the arch on the grass curtain, vegetable seedlings sprinkled to rice husks, grass clippings, etc., to help keep warm and cold, really not, have to raise a small brazier to heat.

Watering, fertilizing, spraying pesticides, and raking weeds are all indispensable. Especially for weeding, the temperature in the greenhouse is high, the vegetables grow fast, the weeds grow faster, and in the absence of herbicides, we have to manually rake the grass, which alone will waste a lot of manpower.

When I grow up, some vegetables have to build a shelf, which is not a headache, the headache is that it must be manually pollinated, and slowly find out the male flowers and point them to the female flowers.

All kinds of vegetables have different requirements for light, ventilation, fertilizer, humidity, temperature, and the harm of pests and diseases is also different, which requires different ways to operate.

Li Guangping was annoyed and asked, "Will you be able to?"

Speaking of which, Li Mo really can't do standard planting, but according to standard planting, the yield per mu of cucumbers is 15,000 catties, and the mu of Cao Zhen is 25,000 catties, how many vegetable farmers can do it?

There are some errors locally, but the general direction is still correct.

The question is not whether it will be, but annoying. It's not annoying, it's bitter. Different from planting crops, it is a meticulous work, soft and hard, and several families are a little uncomfortable with planting vegetables at the beginning, which is very annoying.

Li Mo asked: "Dad, everyone, are you afraid of being annoyed, or are you afraid of being poor?"

In one sentence, everyone was asked.

Li Mo said again: "One acre of garden, ten acres of field, this garden is a vegetable garden, and it is still a greenhouse with high-yield vegetables, can you not be annoyed?"

A few people were silent again.

"This is the beginning, the temperature turns back, and the vegetables bloom, which is annoying. But Dad, everyone, I still want to ask, it is very profitable, but if you want to make money, and you don't have to endure hardship, is it impossible?"

The last two sentences are not important, the important thing is the front, they are all poor, compared with the poor word, what is annoying!
