Description

Technical Field

[0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a high-yield and lodging-resistant corn cultivation method. Background Art

[0002] As one of the most important food crops in the world, the yield and quality of corn directly affect global food security and the stable development of the agricultural economy. However, in the process of corn cultivation, high yield and lodging resistance have always been the focus of attention of farmers and agricultural researchers.

[0003] In order to pursue high yields, farmers often adopt cultivation measures such as dense planting and high fertilizer, which increases corn yields but also increases the risk of lodging. Secondly, improper soil fertility and water management are also important causes of corn lodging. Insufficient soil fertility or too much or too little water will affect the root growth and stem strength of corn, thereby reducing its ability to resist lodging. Summary of the invention

[0004] The purpose of the present invention is to provide a high-yield and lodging-resistant corn cultivation method, which overcomes the shortcomings of the prior art. The soil is treated with a soil treatment agent, and the seeds, soil and leaf surfaces are treated with a growth agent to supplement the fertility of the soil and corn during production, enhance the strength of the corn root system and stalks, and increase the yield and lodging resistance of the corn.

[0005] To solve the above problems, the technical solutions adopted by the present invention are as follows:

[0006] A high-yield and lodging-resistant corn cultivation method comprises the following steps:

[0007] S1. Choose a relatively flat area with gentle slopes, facing the sun and with plenty of sunshine;

[0008] S2. One month before planting, conduct soil testing on the regional plots and configure soil treatment agents based on the soil test results;

[0009] S3. Apply soil treatment agent to the regional plots at a rate of 100-200 kg per mu, and deep plow the soil to more than 30 cm;

[0010] S4. Apply basal fertilizer to the area plot at a rate of 2000-3000kg per mu before planting, and deep plow the soil again;

[0011] S5. Select commercial seeds with bright color, full grains, uniform size, no insects or damage, and above the national standard GB4404.1-1996 second-level improved seed standard, soak the seeds in the growth agent for 2-4 hours, and then dry them in the shade at room temperature for later use;

[0012] S6. When the temperature is stable above 10℃, sow the seeds mechanically. The seeds should be evenly distributed and at the same depth. After sowing, cover the seeds with a thin layer of soil and compact it lightly.

[0013] S7. During the jointing and flaring stages of corn, mix the growth agent and irrigation water in a mass ratio of 1:(10-100) and irrigate the mixture on the roots of the corn seedlings;

[0014] S8. After the corn seedlings have leaves, spray the growth agent evenly on the leaves of the corn every 7-10 days, and spray continuously 2-3 times.

[0015] Furthermore, the soil testing described in S2 includes soil fertility, pH, organic matter content and drainage performance.

[0016] Furthermore, the soil treatment agent comprises the following components in parts by weight:

[0017] 10-100 parts of organic fertilizer, 2-20 parts of seaweed, 10-50 parts of clay, 20-80 parts of biochar, 2-10 parts of biological bacteria agent, 10-100 parts of compound fertilizer, and 5-20 parts of trace element fertilizer.

[0018] Furthermore, the soil treatment agent also includes quicklime / sulfur for adjusting soil pH.

[0022] Furthermore, the biological fertilizer extract includes two or more of Bacillus subtilis, Bacillus megaterium, Bacillus gelatinus, Bacillus licheniformis, Bacillus thuringiensis, Bacillus laterosporus and Streptomyces jingyangensis.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The high-yield and lodging-resistant corn cultivation method of the present invention comprises the following steps: treating the soil with a soil treatment agent, treating the seeds, soil and leaf surfaces with a growth agent, replenishing the fertility of the soil and corn during production, enhancing the strength of the corn root system and stalks, and increasing the yield and lodging resistance of the corn.
