Embodiment Construction

[0015] The invention discloses a high-yield and strong drought-resistant corn planting technique, comprising the following steps.

[0016] (1) Plow the land and apply enough base fertilizer: Before winter, the land should be plowed in autumn, irrigated in winter or spring. The plowing depth should be more than 25cm, and the plowing depth should be the same, and the ridge should be turned evenly; the straw should be returned to the field and the green manure land should be cut, and the plowing should be good. Combined with plowing, all organic fertilizers, 40% to 50% of nitrogen fertilizers, and 70% to 80% of phosphorus fertilizers are used as base fertilizers for full-layer deep application.

[0017] (2) Soil sealing and site preparation before sowing: Before site preparation, use 50% acetochlor 100-150g, or 90% acetochlor 80-100g, water 30-40kg, evenly spray the soil surface to seal the weeds, and then Carry out raking and grinding to prepare the soil to reach the standard r...

Abstract

The invention discloses to a high-yield high-drought-resistance maize cultivation technology. The invention relates to the technical field of agriculture, forestry, husbandry, hunting, trapping and fishing, and especially relates to a maize cultivation method. The high-yield high-drought-resistance maize cultivation method comprises the following steps: (1) land plowing is carried out, and sufficient base fertilizer is applied; autumn plowing, winter irrigation or spring irrigation should be carried out before winter; (2) before sowing, soil sealing and land preparation are carried out, wherein 100-150g of 50% acetochlor is mixed with 30-40kg of water before land preparation; (3) seed treatment is carried out, wherein seeds are coated with a special-purposed seed coating according to local disease and pest occurrence laws before sowing; (4) sufficient base fertilizer is applied; soil water retention and fertilizer retention capacities can be substantially improved after a mulching step in maize cultivation; and (5) cultivation density is controlled, wherein a sowing density is determined according to factors of different cultivation manners, different varieties, different levels, soil fertilities and the like.

Description

technical field [0001] The invention belongs to the technical fields of agriculture, forestry, animal husbandry, hunting, trapping and fishing, and particularly relates to a corn planting method. Background technique [0002] Corn, also known as maize, corn, bract, cob, etc., is one of the main food crops in my country, and it is also a good livestock feed and industrial raw material. The sown area of ​​corn in the country ranks third after rice and wheat. Corn is rich in nutrients, and its grain contains 72% starch, 9.8% protein and 4.5% fat. In addition, it also contains a lot of mineral elements and multivitamins. As food, corn has the characteristics of high calorific value. It is delicious to make various cakes with corn mixed with other foods. Corn is not only an important food crop, but also known as the "king of feed". Every 100kg corn grain contains 270 feed units, and its nutritional value is equivalent to 120kg sorghum and 130kg barley. Pigs, cattle and other...
