Embodiment 1

[0024] 1) Sun-drying: pick plump corn seeds, put them on the ground with a thickness of 5mm, and turn them in the sun continuously for 3 days;

[0025] 2) Seed soaking: Seed soaking in clear water, first soaking in cold water for 12 hours, then soaking in warm water at 55°C for 2 hours, and finally soaking in decomposed urine solution, wherein the mass percentage of decomposed urine and water in the decomposed urine solution is 1:5 , the soaking time is 6 hours;

[0026] 3) Seed dressing: use concentration to be 20% wisterin, 0.3% lindane powder, and No. ABT4 rooting powder to mix. It is 5% of the amount of seeds, and the ratio of water and alcohol added is 105:1. The corn seeds are seed-dressed, covered with a plastic sheet, and left to stand for 6 hours;

[0027] 4) sowing: in the range of 55cm in row spacing and 25cm in row spacing, 2 kinds of single holes, keeping the planting density of corn for sowing;

[0028] 5) Preparation of organic fertilizer: put spirulina chick...

Embodiment 2

[0031] Traditional planting methods:

[0032] Seed selection: select seeds according to conventional methods, and directly sow the selected corn seeds after germination, single hole and single plant;

[0033] Application of base fertilizer: Select fertile soil, convenient drainage and irrigation, and apply sufficient base fertilizer on sandy soil with good ventilation; the base fertilizer is obtained by mixing organic fertilizer and farmyard manure at a ratio of 3:1. The organic fertilizer is a mixture of sheep manure, cow manure, chicken manure, pig manure and wheat straw, and its weight ratio is 2:3:1:3:1.

[0034] Field management: pay attention to anti-staining at the seedling stage, anti-drought in the middle and late stages, and timely anti-pest;

[0035] Harvesting: Harvesting according to conventional methods.

[0036] Before sowing, use 2500 times chlorpyrifos solution for seed dressing.

[0037] In the middle and late stages of corn growth, trichlorfon is used as ...

Description

technical field [0001] The invention relates to the field of crop cultivation, in particular to a method for cultivating high-yield corn. Background technique [0002] my country is a large agricultural country, and agriculture is the foundation of the national economy. However, in recent years, with the development of the economy, the area of ​​agricultural land has been decreasing, and it is imperative to increase food production. Corn is widely used as feed raw material and industrial raw material for consumption, and occupies a pivotal position in my country's crop production. In addition, corn is the grain variety with the most follow-up products, and the deep processing industry using corn as raw material is called the "golden industry". With the continuous development of the corn deep processing industry, the consumption of industrial corn is increasing year by year, becoming the "locomotive" driving corn consumption. [0003] With the development of the modern cor...
