Aggregated cultivating method for cotton in drought region

Abstract

The present invention belongs to a novel technology of the cluster-plantation of the cotton in the drought region, which comprises the land preparation, the watering before sowing, the seed treatmentbefore sowing, the reasonable fertilizer application, the water irrigation in the growing period according to the need, the artificial branch treatment, the top removal, the strengthening of the farmland management and the appropriate picking. The present invention is characterized in that in the planting process of the cotton, the cotton is planted in a two-row strip-shaped planting way; wherein,the distance among the strip, the row and the hill is 50*30*25 to 50*30*30 cm; the density of the hill is 5600 to 6700 hills per Mu; the density of the plant is 17 thousand to 20 thousand plants perMu;using the plantation way of one hill with three plants, when in plantation, one hill is sewed with five to six seeds; in the growth period, three strong plants are reserved on three directions ofnort h, southeast and southwest, which is classified into three layers of the specification; wherein, the short plant is positioned on the southeast in a height of 40 to 50 cm; the intermediate plant is positioned on the southwest in a height of 50 to 60 cm; the tall plant is positioned on the north in a height of 60 to 70 cm; and distance among the three layers is 10 cm. According to the cluster distribution characteristics that the desert plant is adaptive to the serious drought environment and on the premise of not increasing the consumed quantity of the irrigated water, the fertilizer is concentrated to be applied and the water content is effectively used, which realizes the object of improving the yield of the cotton in the drought region.

Description

technical field [0001] The invention belongs to a new technology for clustering cotton planting in arid areas. Background technique [0002] The traditional cotton planting method is the uniform distribution of 1 hole and 1 plant. In recent years, the improved planting method has mostly adopted the planting method of 1 hole and 2 plants. In the traditional planting method, 1 hole and 1 plant is 1 layer, and in the improved planting method, 1 hole and 2 plants are 2 layers. [0003] Most of the existing planting methods are 4-row strip planting and 2-row strip planting. 4 rows of strip planting, the spacing of the holes in the strip is 50×30×20cm, 9500 holes / mu, the density of 1 plant in 1 hole is nearly 10,000 plants / mu, and the density of 2 plants in 1 hole is 19,000 plants / mu; 2 rows of strips Planting, the distance between the holes in a row is 50×30×18cm, 9300 holes / mu, the density of 1 plant in 1 hole is 9,000 plants / mu, and the density of 2 plants in 1 hole is 18,000...

AI Technical Summary

Problems solved by technology

[0005] In order to increase the yield, the existing cotton planting technology uses increasing the density of the plants in the holes as a means. The traditional planting method of 1 hole and 1 plant has a high hole density, which easily causes poor light transmission of the cotton group, resulting in a large number of cotton buds and bolls falling. ; Secondly, it is not conducive to field management, and it is not conducive to the centralized application of fertilizers and water-saving irrigation measures, such as the implementation of micro-spraying and infiltration irrigation; The ability is poor, and the cotton yield is difficult to increase

1 hole, 2 plants improved the planting method. Although the hole density of the traditional planting method was unchanged, the plant density was increased, and the yield was increased compared with the original one. However, the hole density is still large, which is still not conducive to fine management, and the positive interaction between cotton plants relationship underrepresented
