Embodiment Construction

[0011] A method for planting common corn, comprising (1) pre-sowing preparation: pre-sowing preparation includes land preparation and full-layer fertilization; said land preparation is to renovate the fields and borders after thawing in early spring, and use herbicides to carry out chemical weeding on the land, After chemical weeding, harrow the land in time to make the land flat, finely divided and free of weeds; the full-layer fertilization refers to the application of urea and diamine phosphate before turning the land. Apply urea and diamine phosphate before plowing, and apply 20 kg of urea and 25 kg of diamine phosphate per mu. In order to ensure the quality of fertilization, it must be neither heavy nor leaky. The plowing depth is 25-30cm. After plowing, the land needs to be leveled.

[0012] (2) Sowing: Sowing can be done when the ground temperature 5cm below the mulch is stable and passes 12°C, and corn seeds with full grains are selected; mechanical on-demand sowing ...

Abstract

The invention belongs to the field of crop cultivation, and particularly relates to a planting method of common corn, which can improve the yield and the quality of the common corn. The planting method comprises the steps as follows: (1) pre-sowing preparation: the pre-sowing preparation comprises land preparation and whole-layer placement of fertilizers; (2) sowing: when the land temperature of positions 5 cm below films is stabilized at 12 DEG C, sowing can be performed; mechanical spaced sowing is adopted, two pits constitute one planting group, the distance between every two adjacent planting groups is 95 cm, two corn plants are reserved in each pit, and the distance between the pits in each planting group is 48 cm; (3) fertilizer application: 1500 kg of farmyard manure, 10 kg of nitrogen, 4.5 kg of phosphorus, 5.5 kg of potassium and 1 kg of zinc fertilizer are applied per mu; (4) field management: herbicides are sprayed, and thinning, final singling, topdressing and intertillage earthing up are performed; and (5) harvesting. Through the technical scheme, the plant permeability is good, the lodging resistance is high, and the field management and harvesting are more facilitated; in addition, the density is appropriate, and the yield and the quality of the corn can be improved effectively.

Description

[0001] technical field [0002] The invention belongs to the field of crop cultivation, and in particular relates to a method for planting common corn. Background technique [0003] Corn is one of the important crops in our country. The production of corn under the condition of market economy must implement high yield, high quality and low consumption in order to improve market competitiveness. Now, according to the current development pattern of my country's market and the production level of cotton in some places in my country (farmers are planted by small households, the area of ​​land is small, the area of ​​land occupied by households is small, the area of ​​middle and low-yield fields is large, the pests and diseases are serious, and the yield is low), how to improve the quality of corn It is one of the technical problems to be solved by those skilled in the art to develop a corn cultivation method that is suitable for promotion, can improve land utilization rate, and i...
