Embodiment Construction

[0016] The high-yield planting method of winter corn of the present invention is characterized in that it comprises the following steps.

[0017] 1. Sowing time: When planting winter corn, you must choose a frost-free area, and at the same time know the time when the local minimum temperature appears to arrange the sowing time. In order to make winter corn suffer less or no frost damage, the sowing season is generally from late October to November.

[0018] 2. Sowing specifications and density: For high-yield cultivation of winter corn, the sowing specification is standardized cultivation in wide and narrow rows, and the compound belt of wide and narrow rows depends on whether single cropping or intercropping. Single cropping, the narrow row is 50 cm, 2 rows of corn are planted on the narrow row, the row spacing is 40 cm, the plant spacing is 13-17 cm, the wide row is 90-93 cm, and 5580-7140 seedlings are raised per mu; intercropping, the narrow row is 42 cm, planting T...

Abstract

The invention relates to a high-yield planting method for winter corn and belongs to the technical field of planting, and particularly relates to a culture technology of winter corn. The invention provides the high-yield planting method for winter corn which is high in germination rate, strong in frost-resistance and strong in water and fertilizer absorption. The high-yield planting method for winter corn is characterized by comprising the following steps of: I, a seeding stage: a frostless region must be selected for planting winter corn; II, seeding specification and density: for high-yield culture of winter corn, the seeding specification is specified cultivation with wide and narrow row spacing, and a wide and narrow row spacing compound region is determined due to monoculture or intercropping; III, selection of a parcel of field suitable for planting winter corn: a parcel of field which has irrigation and drainage conditions and is loose in soil are selected to plant winter corn, the soil is maintained moist frequently, and robust growth of plants is promoted; and VI, film coverage: as the air temperature is relatively low for winter corn, the field capacity of the soil is reduced as a result of ending of rainy seasons, less rainfall and much wind.

Description

technical field [0001] The invention belongs to the field of planting technology, in particular to the cultivation technology of winter corn. Background technique [0002] Winter corn is an off-season crop, with poor root development, weak ability to absorb water and fertilizer, and less vigorous growth and development than summer-sown corn. For the same variety, winter-sown plants are shorter than summer-sown plants, and the growth period is prolonged. In addition, winter corn is afraid of frost. If it encounters frost during the growth period, the yield will decrease if it is mild, and the grain will not be harvested if it is severe. [0003] Analysis of the reasons for the low yield of winter corn; low temperature disaster is the main factor affecting the yield of winter corn 3°C. Dehong has long sunshine time and high temperature all year round, and the four seasons are not clear. The temperature will still show regular changes with the changes of the four seasons. Ho...
