Increase production and increase income with the new concept of zinc agriculture

Original title: irrigate the "Flower of Life" with "Zinc" Agriculture

Experts inspected the potato zinc application experimental field in Inner Mongolia.

Trace element zinc is known as the "flower of life", crops, the human body can not do without it. In order to promote the new concept of "zinc agriculture and healthy living", since 2010, the National Agricultural Technology Center has cooperated with the International Zinc Association and Canada's Tektronix Resources through the implementation of zinc fertilizer demonstration and promotion projects. strive to create a "zinc fertilizer-food-human body" zinc nutrition cycle chain, so that this "flower of life" beautiful bloom in the field, table.

The question is compelling:

Speed up the promotion of zinc fertilizer

Zinc is a necessary trace element for human health and crop growth. Zinc deficiency leads to a decline in human immunity, especially stunting in children. The soil zinc deficiency in China is serious. According to the test and analysis in recent years, the soil zinc deficiency area has reached about 60%, which is particularly prominent in the arid and semi-arid areas of the north. In order to promote the application technology of zinc fertilizer, since 2010, the National Agricultural Technology Center has cooperated with the International Zinc Association and Canada's Tektronix Resources to implement the zinc fertilizer demonstration and extension project, and put forward the concept of "zinc agriculture and healthy living". Through experimental demonstration, publicity and training, guide enterprises and other work, promote the scientific application of zinc fertilizer technology.

According to the survey statistics of 26 provinces (autonomous regions and cities), the area of zinc fertilizer applied in China exceeded 100 million mu in 2015, an increase of more than 20 percent over the previous year, and zinc consumption reached 60,000 tons. According to the experimental and demonstration data, the application of zinc fertilizer to grain crops increased by an average of more than 5%. In the application of zinc fertilizer, zinc-containing nitrogen fertilizer and zinc-containing compound fertilizer increased rapidly; in the application method, spraying and integrated application of water and fertilizer increased rapidly.

Since 2012, the scientific application of zinc fertilizer has been written into the technical guidance of scientific fertilization for major crops of the Ministry of Agriculture. The recommended amount of zinc fertilizer for wheat, rice, corn, rape, soybean, cotton, fruit trees and other crops is 1kg / mu. Driven by the project, various provinces (autonomous regions and municipalities) have also increased the promotion of scientific zinc application, and put scientific zinc application into the guidance of crop fertilization.

Liu Shunan: 200 yuan more per mu from barren slope to ladder

Liu Shunan, Nailin Town, Karaqin Banner, Chifeng City, Inner Mongolia, transferred 2000 mu of barren sloping land to engage in large-scale management in 2014, all of which were built into terraced fields after transformation. Due to the large turnover of the soil, he invested a lot of compound fertilizer and organic fertilizer in the first year, and laid drip irrigation facilities to fertilize corn with the integration of water and fertilizer, but the corn yield could not come up, which made him difficult.

At the beginning of 2015, the technician of the local soil and fertilizer station carried out soil sampling and testing on his plot and found that the content of available zinc in the soil was less than 0.3 mg / kg, which belongs to the land with serious zinc deficiency. It is suggested that zinc fertilizer be added to the fertilizer formula. According to the guidance of agricultural technicians, Liu Shunan added 0.5 kg of zinc fertilizer per mu in the base fertilizer and added zinc fertilizer in the late topdressing. By the time of harvest, the yield of corn increased by nearly 150 kg per mu and the income increased by more than 200 yuan per mu.

Mei Jinxiang: corn is resistant to drought and disease and has a stable yield

"it has been dry for too long this year, and I am worried about the reduction of corn production. Fortunately, with the application of zinc fertilizer, the corn has three longer leaves than others. " Mei Jinxiang, a villager of Xiyan Village, Anyang Town, Yunyang District, Shiyan City, Hubei Province, recently held the hand of Li Guangfu, director of the district soil fertilizer station.

Since 2014, the district Tufei station has been conducting a pilot project of zinc fertilizer in the village. Mei Jinxiang has tried to sprinkle only one mu of land with 1 kg of granular zinc fertilizer. The autumn harvest is 110 kg more than other plots, an increase of 22%. "Corn kernels have been growing to the top, and less medicine is used if you get sick. This year, using zinc fertilizer can still resist drought. " According to the evaluation of the fertility of cultivated land, more than 30% of the land is seriously zinc deficient in Yunyang District, according to the stationmaster Li. With the support of provincial soil and fertilizer stations, they have carried out experiments and demonstrations of water-saving agricultural techniques since 2013, and have successively demonstrated more than 10,000 mu on sweet potatoes, rice and corn. Through guidance, the level of zinc application in the whole region has increased year by year, and the resistance of crops to drought, cold and disease has been significantly enhanced.

Zhao Wenping: the increase in wheat production drives the big families around

Zhao Wenping is a big farmer in Dong Zhen Zhuang Village, Renxian County, Hebei Province, with 300 mu of contracted land, mainly growing wheat and corn. He bought tractors, seeders, rotary tillers and other machines and realized mechanization. Sprinkler irrigation was installed, and the fertilization system realized the integration of water and fertilizer, and successively applied agricultural machinery subsoiling technology, one spraying and three prevention technology, nitrogen fertilizer backward technology, corn topdressing technology and so on, so as to improve the farming level. Now it is up to him to take care of 300 mu of land, but nothing is lost.

In 2014, Zhao Wenping began to apply zinc fertilizer, the first wheat base application of 1 kg per mu, to harvest 35 jin more than the non-application of one mu of land, corn planting, zinc fertilizer was sprayed once in the seedling stage, as a result, the seedling stage increased the yield by 52 jin. Over the past year, the application of zinc fertilizer alone will increase the income of grain by 26000 jin. Driven by his demonstration, several big farmers around all used zinc fertilizer.

Technical support:

Test and demonstration to verify the effect

To provide technical support for large-scale popularization and application, the National Agricultural Technology Center has formulated and issued the "demonstration and extension Program of Zinc Fertilizer" every year, and carried out the promotion activities of scientific application of zinc fertilizer throughout the country. the experimental demonstration crops, area, zinc application treatment, observation records, result analysis, data submission and so on were standardized and required. In 2015, 22 demonstration sites were set up in 15 provinces (autonomous regions and municipalities), covering 8 kinds of crops, with a total area of nearly 10,000 mu.

According to the collation and analysis of the experimental and demonstration data, the effect of spraying zinc humic acid on tomato leaves is better than that of integrated application of water and fertilizer. The effect of foliar spraying zinc humic acid on wheat was more obvious than that of integrated application of water and fertilizer. Comparing the yield-increasing effects of different zinc fertilizer application techniques, the integrated application of water and fertilizer zinc sulfate was greater than foliar spraying zinc humic acid, foliar spraying zinc humic acid was higher than bottom application of zinc-containing compound fertilizer (or zinc-containing formula fertilizer). Under the condition of applying 2 kg zinc sulfate ZnSO4 ·H2O per mu with the integration of water and fertilizer, the yield increase effect of all kinds of crops was the highest, followed by tomato, rice and wheat.

The industry keeps up with:

Positive interaction in cooperation between agriculture and enterprises

The application of zinc fertilizer is an important way to popularize zinc fertilizer. The National Agricultural Technology Center pays attention to guiding fertilizer enterprises to participate in the production of zinc-containing fertilizers, and large domestic enterprises such as Shandong Kim Jong-da, Shenzhen Batian, Xindu Chemical Industry and Shandong Innovation actively participate in the development of zinc-containing fertilizer formulations and new varieties of fertilizers. The 15 project provinces focus on contacting 73 fertilizer enterprises, and a total of 63 zinc fertilizer formulations have been developed in the whole year, which are recommended to manufacturers.

Through organizing training seminars for fertilizer production enterprises, promoting zinc-containing formula fertilizers, compound fertilizers and water-soluble fertilizers, promoting the production of zinc-containing fertilizers, and guiding enterprises to scientifically market zinc-containing fertilizers. Dr. Fan Minxian of the International Zinc Association attended the second liquid Fertilizer Industry Development Forum, which was attended by more than 300 representatives of related enterprises to train enterprise R & D and marketing personnel on the integration of zinc fertilizer and water and fertilizer technology. The Water Saving Department of the National Agricultural Technology Center sent people to participate in the "third Symposium on the Application and Development of medium and Trace element Fertilizers" and made a special report on "Agricultural Zinc deficiency and Scientific Application of Zinc Fertilizer".

Publicity and popularization:

Carry out technical training at all levels

The National Agricultural Technology Center has successively organized two national technical training in Chifeng City in Inner Mongolia and Dunhuang City in Gansu Province to train agricultural technology extension personnel in the integration of water and fertilizer and the scientific application of zinc fertilizer. In 2015, 5000 color pages of "Technology of Scientific Application of Zinc Fertilizer in Citrus" and "Technology of Scientific Application of Zinc Fertilizer in Apple" were printed and distributed free of charge to Hubei, Hunan, Sichuan, Chongqing, Shandong, Shaanxi and other major citrus and apple producing provinces, in order to promote farmers' attention to zinc nutrition and the application of zinc fertilizer. In the same year, more than 60 activities such as on-site observation and technical discussion on the application effect of zinc fertilizer at the provincial and county level were organized in 22 project demonstration areas to educate farmers to enhance their awareness of scientific application of zinc fertilizer through on-the-spot observation during the critical period of crop growth.
