In mid-May, everyone began to really feel the arrival of summer, and many elderly people often walked around with a sunflower fan. The place where they are most active is naturally under the big oak tree, the old man is playing chess, etc., and the old grandmothers are in groups of three or five to play homely things.

Kwai fan is not a product of Chujiazhai, but Chujiazhai, and even the people of Heqian Town like this kind of fan very much. As far as Chu Jiaqiang knows, this kind of fan is also from Guangdong Province. Will be a specialty.

There are also many varieties of aoi fans. According to different processes and shapes, there are hundreds of varieties such as cow heart fan, chicken heart fan, glass fan, fire painting fan, bleached embroidery fan, bamboo painting fan, and rubber flower weaving fan. There are also 4 different levels of quality.

New. The sunflower fan has always been famous for its round core, fine and uniform bones, white and flexible fan surface, and excellent weaving technology. In particular, its bamboo sticker fan, three-ridge fire painting fan, and double-sided embroidery fan are even more elegant and beautiful, and people can't put it down.

By this time, the seedlings had already grown. Some time ago, those seedlings withered yellow, but many tourists were worried, thinking that it was a rice disease, and it was not light, and it was the same as an infectious disease.

In fact, after transplanting, due to the damage to the root system, the ability to absorb water and fertilizer is reduced, the aboveground part stops growing, and the leaf color turns yellow, and it does not continue to grow until new roots occur.

Moreover, there is often a lack of holes after transplanting, and the seedlings must be checked and replenished in time to ensure the due density and basic number of seedlings. Then. The second aunt spent most of the day inspecting all the paddy fields. That's why the leftover seedlings are generally not thrown away immediately, but kept to continue growing until the seedlings are replenished.

During this period, it is necessary to go to the edge of the paddy field often to watch the water. After the seedlings are planted, they can be irrigated with some water. After two or three days. Fall shallow to about an inch. Small seedlings are transplanted, and shallow water is irrigated about l inch. These are very particular and must be known to experienced farmers. Otherwise, even if you are a college student, you may not necessarily manage these things, and you are really not afraid of your high knowledge.

After eating, Chu Jiaqiang wore a straw hat and went out. Today, it was his turn to look at the paddy fields and remove the weeds from the paddy fields by the way. Let the second aunt take a break.

When he arrived at the paddy field, he found that there was too much water in the paddy field, so Chu Jiaqiang hurriedly opened the gap in the ridge a little bit to drain less water.

During the tillering period, especially during the effective tillering period, rice is generally watered about 1 inch. It can increase the ground temperature and water temperature, promote the decomposition of soil nutrients, and the light and oxygen at the tillering node are sufficient, which can promote the occurrence and growth of tillering. Saline-alkali land should be irrigated with live water to prevent the water quality from deteriorating and harming rice seedlings.

When the effective tillering period is over, deep water should be irrigated to inhibit the occurrence of tillering. When the growth is too vigorous. It can be used to drain the field and control the growth, reduce the ineffective tillers, and have an obvious effect on preventing lodging.

Now. Although it has not yet reached the tillering stage, it should not be too deep and the water will affect the growth of rice.

"I've seen a kind of rice in the north before, and people are growing it on dry land." Li Quan said to Chu Jiaqiang.

They also had nothing to do, so they followed Chu Jiaqiang out to work together. Sometimes, even they feel incredible, and they actually want to do work from time to time, otherwise they will feel uncomfortable.

"Is that upland rice? There are also many varieties of rice. In our south, because there is a lot of water, we all grow flooded rice. There are many more types of this. What we are planting now, everyone generally calls it early rice, which is not very delicious, so everyone in the village likes to use it to make porridge, and the one planted in June and July is called late rice, and the yield will be a little less, but it is delicious. Chu Jiaqiang explained.

Upland rice, drought-tolerant, suitable for dryland planting of cultivated rice, also known as upland rice, generally refers to the cultivated rice that can adapt to grow in the boundless dryland, slope land and arid ecological environment, is a variant of rice.

This kind of rice is also of great significance, and dry rice farming can make full use of natural precipitation, so that rice planting is no longer limited by artificial irrigation, so that the rice planting area can be greatly expanded and rice yield can be increased.

In addition, it is conducive to the transformation of low-lying land, water and sandy land, riverside, and mountain water outlet. The paddy fields planted in such plots lack irrigation conditions, and the dry fields planted are prone to waterlogging in summer, and the perennial grain output is extremely low.

"Even we can't always soak in water, sometimes it will rot. When they first set head, they will need a little more water, and their drought resistance is the weakest at this time, and after this period, it will be much better. Chu Jiaqiang said to them.

According to the experience of the peasants, it is necessary to irrigate the water for "nourishing the fetus" and dry the fields in a timely manner. The panicle differentiation stage of rice is the period when rice grows fast and requires the most water in its lifetime, and it is the period when drought tolerance and cold tolerance are the weakest.

If there is a lack of water, the young spike will be affected first, which will not only affect the normal development of pollen grains, but also affect the transport of nutrients to the panicle, which will easily cause short ears, less grains and more empty shells, so we must pay attention to the management of water. At this time, it is the height of summer, the sunshine is strong, the temperature is high, and the water temperature can be controlled by deepening the water layer appropriately. Generally, the water layer is kept 2-3 inches deep.

But when it comes to fruiting, the practice has to be changed. The general principles of rice management during this period are: to raise roots, protect leaves, prevent premature leaf aging, promote large grains and satiety, and prevent empty shell grains.

"When it comes to the fruiting period, it is necessary to irrigate reasonably and drain water in a timely manner. During the flowering period, it is still necessary to maintain a certain water layer in the field, adjust the water temperature, and increase the air humidity to facilitate flowering and pollination.

To the grouting period, take dry, dry and wet, wet-based irrigation method, that is, after irrigating water once, it will naturally dry out for 1 or 2 days, and then irrigate again. In this way, the purpose of nourishing roots with air and preserving leaves with water can be achieved, which is conducive to promoting grain filling and preventing premature aging.

Entering the wax ripening period, it is necessary to adopt the irrigation method of dry, dry and wet, mainly dry, and after irrigating once, it will naturally dry for 3-4 days, and then irrigate. In the later stage, drain the water 7-10 days before harvesting. Chu Jiaqiang told them the trick of managing rice.

"Huh! It may sound complicated to you, but it's actually quite simple. Because what I just said is about a month, so you can pay attention to it and complete it. Chu Jiaqiang continued.

"It seems that we are not the material to be farmers, but you guy, not to be a farmer, it is indeed inappropriate!" Chen Wu said with a smile.

The others also nodded, speaking of these farm jobs, they couldn't keep up with Chu Jiaqiang's rhythm even if they were pat horses. In the words of Professor Wen and other old people, Chu Jiaqiang is serious, even if he is an old farmer who has cultivated the farmland all his life, he may not be able to compare with this guy.
