Problems solved by technology

Due to the large difference in the fertilizer requirements of corn and soybeans, the planting area is large, and in order to ensure the yield of corn and facilitate mechanized operation during production, the type and quantity of fertilizer required by corn are generally used as the base fertilizer for one-time application in combination with plowing before sowing. Causes a lot of fertilizer waste, high cost, prosperous soybean growth, decreased yield, low fertilizer utilization rate, and aggravated pollution, etc.

Embodiment 1

[0019] It was carried out at the Renshou test site in Sichuan. The corn in the production was selected from Chuandan 418, which is widely popularized in production, with moderate fertilizer tolerance, and the soybeans were selected from Nandou 12, which has better shade tolerance. Day) Simultaneous machine planting, the density is designed to be 3500 plants / mu of corn, 8000 plants / mu of soybeans, the width of corn and soybeans is 2 meters, the narrow row spacing of corn and soybeans is 40 cm, and the spacing is 60 cm. and special fertilizer treatment, the test results are shown in Table 1:

[0020] Table 1

[0021]

[0022] Note: No fertilization treatment: do not apply any fertilizer; special fertilizer treatment: a fertilization method that combines special base fertilizer and special seed fertilizer. Sow, apply 40kg per mu. The special seed fertilizer is based on the type and amount of fertilizer required for corn. When combining corn sowing, ditch fertilization at a di...

Embodiment 2

[0025] It was carried out at the Yongcheng test site in Henan Province. The corn was selected from Zhengdan 958, and the soybean was selected from Jidou 21. The corn and soybean were sown at the same time after the wheat harvest (June 5). The density was designed to be 4,500 corn plants / mu and 9,000 soybean plants / mu. , the width of corn and soybean is 2.2 meters, the narrow row spacing of corn and soybean is 40 cm, and the spacing is 70 cm. Conventional fertilization treatment and special fertilizer treatment are carried out respectively. The test results are shown in Table 2:

[0026] Table 2

[0027]

[0028] Note: Conventional fertilization treatment: The amount of fertilizer used in conventional fertilization is the same as that of special fertilizer, combined with machine-sown corn phosphate fertilizer and potassium fertilizer as base fertilizer for one-time application. Application; special fertilizer treatment: as described in Example 1.

[0029] The results of thi...

Embodiment 3

[0031] The experiment was carried out in Huining, Gansu Province. Shendan 16 was used for corn, Qihuang 36 was used for soybeans, and corn and soybeans were sown at the same time on May 8. The density was designed to be 4,500 corn plants / mu, 18,000 soybean plants / mu, and corn and soybean bandwidth of 2.2 The narrow row spacing of rice, corn and soybeans is 40 cm, and the spacing is 70 cm. Conventional fertilization treatment and special fertilizer treatment are carried out respectively. The test results are shown in Table 3:

[0032] table 3

[0033]

[0034] Note: Conventional fertilization treatment: the amount of fertilizer used in conventional fertilization is the same as that of special fertilizer, combined with machine-sown corn phosphate fertilizer and potassium fertilizer as base fertilizer for one-time application, nitrogen fertilizer is applied according to the ratio of base fertilizer: jointing fertilizer 5:5, soybean fertilizer phosphorus fertilizer and potassium f...

Abstract

The present invention relates to a corn soybean strip intercropping specific fertilizer and a fertilization method, and belongs to the technical field of crop fertilization. The corn soybean strip intercropping specific fertilizer includes a special base fertilizer and a specific seed fertilizer, the total oxygen content of the special base fertilizer is 40%, according to the soybean fertilizer requirement type and fertilizer requirement amount, the special base fertilizer is applied and spread in a whole field by combination of turning over and ploughing in the amount of 40kg per mu; the total oxygen content of the special seed fertilizer is 35%, according to the corn fertilizer requirement type and fertilizer requirement amount, and during corn planting, the special seed fertilizer is applied and spread by trenching at the position 10-15cm apart from a corn planting row in the amount of 40kg per mu, wherein micro element fertilizers comprising 1000g of zinc sulfate, 500g of boric acid, 5g of ammonium molybdate and 100g of ferrous sulfate are applied to one mu field. The two special composite fertilizers and matched fertilization technology are developed on the basis of fertility properties of crops for rotation of crop nutrient interaction and zoning crop rotation under corn soybean strip intercropping planting pattern and according to corn soybean fertilizer requirement rules, and efficient nutrient use and double high yields of intercropping groups can be achieved.

Description

technical field [0001] The invention relates to a special fertilizer for corn and soybean strip intercropping and a fertilization method, and belongs to the technical field of crop fertilization. Background technique [0002] The basic national conditions of a large population and a relative shortage of arable land resources determine that my country's agriculture must take a high-yield and sustainable path. Since the beginning of the new century, high-input and high-yield crops such as rice and corn have developed rapidly, and grain output has achieved a historic "12 consecutive increase", which has made important contributions to ensuring the effective supply of grain. However, at the same time, the area of ​​land-raising crops for soybeans has declined sharply, the gap between supply and demand is growing, and the soybean industry is at risk; and a series of problems such as excessive consumption of soil fertility resources, sharp decline in the quality of cultivated land...
