On August 20, the twelfth day of the Olympic Games, in the women's windsurfing competition at the Qingdao Olympic Sailing Venue, the national team won the first gold medal in the history of Olympic participation.

In his previous life, as a poor man, he could only watch the Olympic events on TV. This time, Qi Zheng not only took his girlfriend Tian Yuwei to participate in the opening ceremony of the Olympic Games, but also watched a number of wonderful events in the capital at close range, and only after satisfying his wishes did he go all the way south.

After watching the Olympic regatta, I went south and first came to the blueberry plantation in Ganyu County.

He is not surprised that blueberries have become the "hot" fruit of the Olympics.

After all, the scarcity of blueberries is still evident now, and the sooner you start a blueberry plantation, the more money you make.

Not only the direct sales of supermarkets, but also the blueberry orchard opened by Jialan Fruit Industry, there is also an endless stream of tourists who come here.

Tian Yuwei also walked into the blueberry field with a basket and experienced the fun of picking. On the blueberry tree, blueberries are green, light purple, and dark purple in clusters. The dark purple blueberry fruit is fuller and thicker, and the darker the color, the higher the ripeness. Tourists shuttling through the green trees and picking blueberries are not only a taste bud enjoyment, but also a kind of tranquility and pleasure of returning to the countryside.

Qi Zheng was learning about the current situation of blueberry sales with Huo Bin on the side.

"Although the initial investment is large, the gross profit of our blueberry planting can reach 70%~80%, which is an absolute high profit. Huo Bin said excitedly to Qi Zheng.

Of course, no matter how high the profit is, it is impossible to recoup the investment in a year, but it is enough to see a wonderful prospect.

Not to mention the income of Jialan Fruit Industry itself, after entering the harvest season, because the harvesting of blueberries needs to be picked manually, the radiation has driven 20% of the county's labor force to increase income.

In particular, those farmers who join the cooperative to grow blueberries are expected to earn at least 100,000 yuan per household this year.

Seeing Huo Bin's satisfied appearance, Qi Zheng had to pour cold water on him: "Don't be careless." If there is demand, there will be supply, no one is blind, everyone sees that blueberries are very profitable, and they must rush to the blueberry plantation. At that time, life will not be so good......"

In my memory, about 09 years later, because of the booming sales of blueberries, a blueberry planting boom was set off in various places, and there was even a crazy scene of "piling up" planting in many areas.

After the blueberry growers and blueberry planting area have been significantly increased, the consequences of the spontaneous reaction of the market have appeared, the price of blueberries has fallen again and again, and blueberries have been downgraded from luxury goods to ordinary fruits, a common problem in domestic agriculture, and when they see the benefits, they will flock to it, and then no one can make money.

was reminded by Qi Zheng like this, Huo Bin also calmed down.

"The overall price of our blueberries has already lowered the import price, although it is conducive to expanding the consumer market and allowing more people to share the delicious taste of blueberries. However, with further increases in production and stable production, coupled with the increase in labor costs, market pressure will indeed increase. ”

Of course, both of them know that blueberry cultivation is a long-term project after all, and the market popularity can be maintained for at least ten years.

It's just that people have no immediate worries, but they must have distant worries.

Qi Zheng suggested: "In order to build a real 'blueberry capital', Jialan Fruit Industry must consider extending the blueberry industry chain, developing deep-processed products, such as dried fruits, fruit wine, jam, etc., from product production to brand building, to enhance the added value ......of blueberries;

Huo Bin was thoughtful.

......

After tasting the freshest blueberries, Qi Zheng came to the final destination of the trip, the seaweed farm and seaweed fertilizer production base in northern Jiangsu, not far from Ganyu County.

"The moss is crazy!" said Yao Jianyi, an oceanographer who jointly studied mutated moss, to Qi Zheng who came to inspect in an inexplicable tone.

After entering the middle of summer, with high water temperature, sufficient light, and relatively calm wind and wave conditions, the mutated moss cultivated by Jiagu seems to have touched the threshold of rapid cell division and growth, and it is really explosive growth Now the moss breeding base can harvest a stubble in less than ten days.

"A large amount of nitrogen and phosphorus nutrients are continuously discharged into the marine water body, resulting in the eutrophication state of the water body, which provides unique conditions for the outbreak of the moss. It's a pity that the scale of cultivation of mutant moss is still limited by the production of mutagens and cannot be promoted quickly, otherwise this year's green tide may not have broken out. Yao Jianyi said regretfully.

Qi Zheng was noncommittal.

Before the Olympics, the green tide along the coast of Lu Province still broke out, but compared with Qi Zheng's impression, it should be said that there were some positive changes, and the outbreak time was later, and the area was not so large.

It should be known that before the outbreak of the green tide, a large number of seaweed breeding rafts in the shallow area of northern Jiangsu provided important conditions for the early attachment of the moss, and after the water temperature increased, it fell off from the rafts and became the main source of floating green algae.

Jiagu tens of thousands of acres of mutant moss breeding base, without applying any chemical fertilizer, in the eutrophication of the water body stubble after stubble crazy growth, through the "blue wave Qinghua array" drainage, equivalent to stubble after stubble consumption of nitrogen, phosphorus and other enriched nutrients in the sea area of northern Jiangsu, purified seawater.

The nutrients from the early source of the green tide were "robbed", the amount of moss exported naturally decreased, and the outbreak of the green tide was also controlled to a certain extent.

However, as long as the irrational exploitation and utilization of water resources by coastal people does not change, and the situation of coastal eutrophication does not change, the threat of green or red tide eruption will always exist, unless the cultivation of mutant moss in Jiagu can be promoted on a large scale, as Yao Jianyi said.

However, whether it can be promoted on a large scale depends on the yield of reproduction inducers and the ratio of income to input.

"How is the research on the development and utilization of mutant moss?" Qi Zheng asked.

Yao Jianyi's spirit was lifted: "In addition to being used to produce green manure, we have successfully converted the mutated moss into biomass oil after many research and exploration, using the hydrothermal liquefaction process. ”

"Although biomass oil is a low-grade fuel, it can also be further refined to obtain different grades of biomass liquid fuel or chemical products, but this needs further research ......"

Qi Zheng was a little surprised, but he still waved his hand and said: "Let's talk about the production and application of green manure first, the group has a big plan and needs a lot of organic fertilizer!"

This big plan is the great development of the desert.

Even with water resources, it can be difficult to keep sand and green the desert.

Qi Zheng tried, holding a handful of sand in the desert, no matter how tightly his fists were clenched, in the end, the sand as thin as powder would slowly slip between his fingers, and it was not easy for this pervasive sand to be fixed. Secondly, the sand is very fluid, and when you dig a pit in the ground with your hand, a gust of wind blows, and the pit in the ground disappears. If there are no effective ways to improve the soil, it is a joke to engage in agricultural development.

The soil that is truly suitable for agricultural development is alive.

Each side of the soil should contain a large number of bacteria, microorganisms and soil animals, which depend on plants for survival, forming an efficient and interdependent living system.

At the same time, the basic minerals in the soil are well preserved and the soluble substances are not carried away by the rain, so the soil retains its aggregate structure, and there is no better home for the growth of crops.

Organic fertilizer is a great tool for improving sandy soil, compared with chemical fertilizer, organic fertilizer can provide more comprehensive nutrients and functional microorganisms.

Yao Jianyi also roughly knew about Jiagu's crazy plan, and said with some excitement: "The production and application of seaweed fertilizer has been relatively mature, and we have developed many varieties of refined seaweed fertilizer, microbial seaweed fertilizer, compound seaweed fertilizer and so on. The frenzied production of mutant moss has also greatly reduced the production cost of seaweed fertilizer...... It's a wonderful way to move nutrients from eutrophicated seawater to barren deserts!"
