The elderly with agricultural materials are looking forward to the high yield of organic matter in spring.

Original title: "Green Spring" in the mind of an old man with agricultural materials

In the rural grass-roots ecology of our country, there is a special group called agricultural people. They are farmers, but they are engaged in selling agricultural materials; they are businessmen, but they provide technical guidance on fertilization and medicine to the villagers; they are "local experts", but they have taken up the burden of popularizing agricultural technology and new agricultural products. It can be said that at the stage when the agricultural technology extension system has not yet achieved full coverage and the new type of professional farmers have not yet fully become the main force, they are indispensable to the green and sustainable development of China's agriculture and the realization of the goal of increasing farmers' income and becoming well-off.

Xu Jiang introduced the bio-fertilizer formula package to the farmers who came to study in the agricultural aid store.

On March 27, the reporter came to the Shenbei seed Agricultural Materials Wholesale Market in Shenbei New District, Shenyang City, Liaoning Province. All kinds of stores selling pesticides, chemical fertilizers, and seeds were next to each other, and there was a storefront called "Green Spring Science and Technology Agricultural material Center". The storefront was ordinary, and even looked a little small compared with the surrounding stores.

However, this store is the concentration of Xu Jiang's adherence to the "green" concept.

Xu Jiang used to be a teacher, is still a teacher, with retirement as the dividing line, before talking about "aerospace lessons," and then teaching "agrotechnical lessons." Focus on biological fertilizers and biological pesticides, according to different crops to launch green package cultivation technology, nearly 80 years old, still running in the farmers' greenhouse to promote technology, still waiting for the arrival of biological fertilizers and biological pesticides "green spring". Still delving into farmers' practical planting techniques of organic green agricultural products.

With the combination of medicine and fertilizer, there is much less medicine.

"Mr. Xu, it's my dear person. if the net income exceeds 100000 this year, those who come out will invite Mr. Xu to dinner, ." Lan Lili, a big vegetable grower in Dawan Village, Yujiafang Town, Liaozhong County, Shenyang City, Liaoning Province, said while busy collecting turnips. "Mr. Xu" is Xu Jiang, which is what farmers call him, but before she met Xu Jiang, Lan Lili did not like to plant a greenhouse.

In 2012, Lan Lili, 31, had to stay at home to take care of her children and earn money, so she set up a greenhouse to plant in the village. However, her lack of experience and years of compensation basically made her lose confidence in planting. At one point, she contracted most of the greenhouses to others, but she only left two. At the beginning of last year, the vegetable market was not good, and the contractors left without even saying hello. In desperation, she had to plant all the greenhouses again.

In April last year, during a low temperature, the grapes in Lan Lili's greenhouse got Botrytis cinerea and sought treatment everywhere. Just in time for the green spring science and technology agricultural materials business staff to the village to do promotion, the business staff asked her to find Xu Jiang directly. After diagnosis and treatment, Lan Lili's greenhouse avoided losses.

The reporter saw that the grapes, tomatoes and beans planted in her greenhouse were all green and neat. She said: "the most troublesome thing to plant a greenhouse is to administer medicine. When I had a disease last year, I basically went to the ground with a cartridge on my back every day, sometimes twice a day." This year, according to teacher Xu's package, we will play every 7-10 days, giving priority to prevention, which can save us trouble! "

"Prevention is the first priority, and persistence is the most important thing. If the frequency of medication is reduced, the dosage will be much less than before. Although bio-pesticides are a little more expensive, they are used less. In this way, the farmers still save, and the key is that the effect is good. " Xu Jiang said that led by the "green" concept, it stems from the public demand for green, organic and other agricultural products. In recent years, Xujiang has formed its own set of bio-fertilizer and bio-drug formula package system, which has been practiced and promoted continuously by means of dealer network and direct guidance to farmers.

Can teach both spaceflight and agricultural skills.

In 1998, Xu Jiang was suffering from tracheitis when he was about to retire as a teacher at Shenyang University of Aeronautics and Astronautics. In the process of seeking medical treatment, I learned that "chitosan" can improve human immunity. He tried to be effective, but Xu Jiang thought about another thing: "this thing has an effect on human diseases, and it should also have an effect on plants."

It is this simple idea that has transformed him from a "teacher who trained aerospace talents" to a "technician who serves farmers" in the past 20 years.

In 1999, at the "chitosan" seminar, Xu Jiang met Wang Shikui, a researcher from the Planning, Design and Research Institute of the Ministry of Agriculture. At that time, Wang Shikui was studying the application of chitosan in agriculture, and achieved some results. Xu Jiang brought the results back to Shenyang and went to rural areas to popularize them, and farmers used them effectively. Since then, Xu Jiang has embarked on the promotion of biological pesticides and biological fertilizers.

"at present, there are a lot of biological fertilizers and drugs on the market, which are mixed with fish and dragons. it is very difficult to certify, and the effect is not very good to say. Teacher Xu has done a lot of screening in this respect." Said Wu Jianli, technical consultant of Shenyang Liuhe Ecological Park, which uses Xujiang biological fertilizer and medicine package. Although he is getting older and older, Xu Jiang did not stop. He went to agricultural products exhibitions all over the country and looked at nothing but biological pesticides and biological fertilizers.

It is precisely this persistence that Xu Jiang formulates the whole process of biological fertilizer (package) technology for different crops, such as grapes, cucumbers, strawberries, beans, leafy vegetables, and so on. In the interview, the reporter saw that the package was specific to the type, quantity and number of fertilizers used in each cultivation and management link, and calculated the drug price in detail. Farmers and dealers as long as a piece of technical paper in hand, a season of planting and guidance. Lan Lili said, "this technical paper is the prescription prescribed by teacher Xu. I am like a 'fool' who can take the medicine according to the prescription!"

Can you have both "organic and green" and "high yield"

On the morning of March 27, tour buses pulled tourists into the Liuhe Ecological Park on the outskirts of Shenyang. The tourists went into the greenhouse to pick and taste strawberries. Liuhe Ecological Park has been in operation for more than a year, has begun to take shape, and the quality of strawberries has been recognized. The strawberries grown in Liuhe Ecological Park were awarded the gold medal at the 11th China (Liaoyang, Liaoning) Strawberry Culture Tourism Festival and China Strawberry Competition.

These strawberries use the "strawberry cultivation throughout the use of biological fertilizer (package) technology (2015-2016)" launched by Xu Jiang. For Wu Jianli, Xu Jiang's technology was chosen because the ecological park should develop in the direction of green food certification and organic food certification.

Wu Jianli said: "the most important thing in the certification is the detection indicators in the soil, while for intermediate inputs such as medicine and fertilizer, it mainly depends on the purchase account of agricultural materials in the ecological park. To a large extent, what kind of medicine and fertilizer are used depends mainly on the independent regulation ability of the ecological park. We really want to do organic agriculture, and Mr. Xu's technology meets the needs. "

With the improvement of people's living standards, people pay more and more attention to food safety, more and more people will choose organic or green food. But there are many different views, and some people attribute food health problems to pesticides and fertilizers. Reporters often hear in interviews that "our vegetables are free of pesticides and chemical fertilizers," and that "without chemical fertilizers, the output of only organic fertilizers will be much lower, and the diseases and insect pests will be very serious." even "organic" and "green" have become marketing gimmicks for some businesses. People realize that there are still many problems to be solved in the self-discipline and supervision of the "green" industry.

The demonization of pesticides and fertilizers by the public is not due to the bad quality of pesticides and fertilizers, but to the serious overuse of pesticides and fertilizers. Reasonable and regular application can produce safe food.
