A total of 96.6 million mu of 96.6 million mu of soybeans will "counterattack" the expansion of soybeans 丨 I am a party representative

Yang Wenyu, a professor at Sichuan Agricultural University, adhered to agricultural scientific and technological innovation in 22 years, so that "soybean corn band -shaped composite planting technology" was written to the Central No. 1 document twice. It was widely promoted across the country. contribute. His technology has also moved all the way to international, and has been widely praised in Pakistan and other countries, providing Chinese ideas for solving the world's grain and oil problems.

How to grow more than 100 kilograms of soybeans with one acre of corn land?

Recently, with the list of representatives of the 20th National Congress of the Communist Party of China, Yang Wenyu and his team professor of Sichuan Agricultural University with 23 years of agricultural scientific and technological achievements: soybean corn band -shaped planting technology, entering the public vision Essence

Through the "selection of varieties, expanding light, and reducing planting confidentiality, the number of corn plants in the acres of corn is unchanged and the yield per mu is unchanged. Since 2003, the cumulative promotion of an area of ​​57.58 million acres in Sichuan has spread to 61 counties and cities. It has promoted 96.6 million acres in the country, and wrote twice to the Central Committee.

In the season of the joy of harvest, Yang Wenyu said that in the future, the team will lead the team to jointly assault and achieve efficient and intelligent soybean corn machine collection. neck".

Ten years

From options to mechanized farming species

In 2012, the outline of the "soybean corn band composite technology" has basically formed, but the supporting fertilization and weeding technology are still exploring, and the level of mechanized cultivation is low. Looking at the whole country, the high -yield demonstration films are only Shandong and Henan. Increasing production and expanding beans, there is still a long way to go.

In 2013, the Central Agricultural Office issued a rural report report, which specifically affirmed the "corn and soybean band -shaped composite technology", and said that it was of important strategic significance for "national food security." The report encouraged Yang Wenyu and his team, and also gave them confidence to persist.

One particle in summer, tens of thousands of food in autumn. To achieve a bumper harvest, seeds are the foundation. Starting from the Huanghuaihai area, Yang Wenyu's team opened the "battlefields" in the northwest of Gansu and Ningxia, and went deep into Hebei, Inner Mongolia and other places, screening for soybean varieties suitable for shade, density, and opportunities for different regions, and formed. The localization technology model.

In order to achieve Yitian double -collection and full -process mechanization, Yang Wenyu's team cooperated with agricultural machinery companies to develop an integrated sowing machine with soybean corn band -shaped planting. Sowing to fertilize.

In response to the harvesting of the two crops, Yang Wenyu's team developed small and medium -sized soybean harvesters and high -ground leap corn harvester through cooperation with agricultural machinery companies and universities to easily complete soybean corn segmentation machines.

With the development of this technology, many provinces and cities have seen its prospects. In 2018, the deputy mayor of Salin Town, Baotou, Inner Mongolia took the initiative to contact Yang Wenyu, and proposed to be a demonstration locally. Yang Wenyu's team conducted online guidance to them through telephones and the Internet. In the first year, 200 acres of test fields were used to use 200 acres of land. Corn and soybeans received more than 800 kilograms and more than 120 kg respectively. Essence

In 2019, Yang Wenyu led the team to provide technical guidance for farmers to achieve the average corn out of 520 kg and 121 kg of soybean.

Yang Wenyu introduced that the successful pilot of the two areas promoted the large -scale promotion of this technology in the Huanghuaihai area and wrote it into the central document.

Deep cultivation of "steady grain to add beans"

Technology helps food safety

Soy corn band -shaped composite planting is not to plant two crops together. Yang Wenyu emphasized that the growth of corn and soybeans is different, and spatial dislocation matching is made to achieve composite planting, grain and soyle wheels, and double collection.

In fact, as early as twenty years ago, Yang Wenyu had started the research of this technology. In the past, in the Shuzhongqiu District, dry land wheat, corn, and sweet potato were planted, that is, "wheat corn and potato" prevailed.

The three crops of wheat croissance are consumed, and it is easy to cause soil loss. "Initially, it was to solve the problem of soil and soil loss brought by wheat and potato, and the problem of soil fertility declined." Yang Wenyu said.

Around 2000, he began to set up a team to start the development of the "Mai Jade Bean" New Three Ripe Set Model Model Model, of which the new type of soybean corn -type seeding technology was the top priority. In 2006, the corn set soybean test field of Yang Wenyu's team achieved no reduction of corn, and soybean was produced more than 100 kilograms per mu. The following year, the "Mai Jade Bean" New Three Cooked Room Set was written into the Sichuan Provincial Party Committee No. 1.

Yang Wenyu recalled that starting from 2010, the market's demand for soybeans has risen rapidly. "Chinese families have increased consumption of meat and dairy products. The growth of meat consumption has led to an increase in demand for animal feed. Soybeans as agricultural products that provide protein feed have increased significantly." Analysis.

Data show that my country needs 250 million tons of corn and soybeans for all year round. To produce enough corn and soybeans, it takes nearly 1.5 billion mu of sowing area.

Corn and soybean belong to the same seasonal dry grain crops. In limited cultivated land, two types of agricultural products staged an irreplaceable "conflict". "There are so many fields used to cultivate corn and soybeans every year. If you want to expand beans, you will definitely occupy the cornfield." Yang Wenyu said. "Only by coordinating the development of corn and soybeans can we respond to the safety of my country's corn and soybeans under the new situation of international trade, and can the Chinese people's high -quality protein in our own hands." In order to get rid of import dependence as soon as possible, Yang Wenyu and the team continuously improved soybean soybeans Corn band composite planting technology provides effective ways to ensure the safety of national corn and increase the self -sufficiency rate of soybeans.

Make up technical shortcomings

Guarding the safety of national grain beans

Since the beginning of this year, the Ministry of Agriculture and Rural Affairs has promoted 15.1 million mu of large bean corn band -shaped planting demonstration and promotion demonstrations in 16 provinces across the country, of which Sichuan Province expanded 3.1 million mu. As Yang Wenyu, like a migratory bird, leads the team members to promote demonstration technology from south to north. It is a common thing to walk a few points a day, and it is common to work for 12 hours a day.

Some time ago, there was a repeated epidemic in Chengdu. Yang Wenyu was at home and remembered how much soybean pods were remembered by thousands of miles away? Is the corn rod grow taller? "This year's large -scale promotion can achieve corn non -reduced production and collect 100 kilograms of soybeans per mu." He said silently. Although he couldn't visit the scene, Yang Wenyu was still confident.

When he learned that he was elected as the 20th National Congress of the Party, his heart was calm. Yang Wenyu said that work can be recognized by the party and the government, which is very relieved. "Whether it is a party representative or not, I am always a party member. Continue research and promotion of soybean corn band -shaped planting technology, increase the production of 'Chinese beans' output, and make ordinary people eat better and better."

Although it has found the technical path to solve the problem of the corn and soybeans in my country, Yang Wenyu said that this does not mean the arrival of the end. For the science and technology team, there is still a long way to go.

According to the "Fourteenth Five -Year" planting industry issued by the Ministry of Agriculture and Rural Affairs, by 2025, China will increase soybean output from 16.4 million tons in 2021 to 23 million tons to improve the self -sufficient ability of oil seeds.

"In the next step, I will lead the team to promote the joint research of more units, realize the efficient and intelligent collection of soybean corn machines, and promote the application in the country's production areas." Yang Wenyu thought about the scene of soybean harvest in the future. "There are 650 million mu of corn cultivated land in the country. If you can use 500 million acres of land as soybeans, you can produce 55 million tons of soybeans a year, plus 30 million tons of soybeans, my country will basically realize soybean self -sufficiency."
