specific Embodiment approach 1

[0015] Specific embodiment one: a kind of high-yield sowing method of cotton in salinized soil in this embodiment includes site preparation, seed selection, sowing, field management, and harvesting, and the sowing steps are as follows:

[0016] The method of planting two rows of cotton in each ridge is adopted, the row spacing of the two rows of cotton in the ridge is greater than 10cm, the plant spacing is greater than or equal to 25cm, and the ridge spacing is greater than 25cm, and the ridge spacing is the distance between two adjacent rows of cotton inside the adjacent two ridges;

[0017] The planting method of two rows of cotton in the ridge is:

[0018] Film mulching cultivation, laying drip irrigation belts in the ridge, the sowing method of the first row of cotton is planted in the way of single grain, double grain, single grain and double grain alternately, and the sowing mode of the second row of cotton is according to the method of double grain, single grain, double...

specific Embodiment approach 2

[0023] Embodiment 2: This embodiment is different from Embodiment 1 in that the distance between the two rows of cotton in the ridge is 10 cm to 15 cm. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0024] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that the distance between the plants is 25cm. Others are the same as in the first or second embodiment.

Abstract

The invention relates to a high-yield sowing method for cotton in salinized soil, which relates to a high-yield sowing method for cotton. The purpose of the invention is to solve the technical problem of cotton yield decline in moderately and severely salinized soils. The method adopts the method of planting two rows of cotton in each ridge, the row spacing of the two rows of cotton in the ridge is greater than 10cm, the spacing between the plants is greater than or equal to 25cm, and the ridge spacing is greater than 25cm, and the ridge spacing is the distance between two adjacent rows of cotton in the inner side of two adjacent ridges; Film mulching cultivation, laying drip irrigation belts in the ridge, the sowing method of the first row of cotton is planted in the way of single grain, double grain, single grain and double grain alternately, and the sowing mode of the second row of cotton is according to the method of double grain, single grain, double grain Grain and single grain are planted alternately, and the sowing density is 15000 plants / mu; the output of planting cotton in moderately and severely salinized soil by the method of the present invention is 289.2kg / mu~324.2kg / mu; Compared with the method, the yield is increased by 11.64% to 13.99%.

Description

technical field [0001] The invention relates to a high-yield sowing method for cotton. Background technique [0002] Cotton has certain salt tolerance and can grow normally on mildly salinized soils, but its seedling emergence rate is inhibited and yield decreases on moderately and severely salinized soils. Contents of the invention [0003] The object of the invention is to provide a high-yield sowing method for cotton in saline soil to solve the technical problem of cotton yield decline in moderately and severely salinized soil. [0004] A high-yield sowing method for cotton in saline soil, comprising site preparation, seed selection, sowing, field management, and harvesting, wherein the sowing steps are as follows: [0005] The method of planting two rows of cotton in each ridge is adopted, the row spacing of the two rows of cotton in the ridge is greater than 10cm, the plant spacing is greater than or equal to 25cm, and the ridge spacing is greater than 25cm, and the ...
