Problems solved by technology

[0002] Conventional insect-resistant cotton in the prior art, artificial pruning and pruning is time-consuming and laborious. The leaves of conventionally cultivated insect-resistant cotton are densely overlapped, and the middle and lower leaves of the cotton plant are seriously shaded from each other, which affects photosynthesis. Less, low output, poor quality

Embodiment Construction

[0005] The present invention is described in detail below in conjunction with embodiment, embodiment establishes three repetitions, three rows of district planting, equal row spacing 1.0 meters, row length 10 meters, plot area is 0.003 hectares, three stem cotton density processing is: 15000 hm 2 、18000·hm 2 , 21000 trees·hm 2 、24000·hm 2 , there are four 1.3-meter-wide roads between each repetition, and various three-row protection lines on both sides of the test site, and four-meter-long protection belts are planted at both ends of the test site. The total length of the land is 43.2 meters, and the width is 24 meters. The area is 0.1037 hectares, all of which are covered with single-row plastic film, and the variety is conventional insect-resistant cotton Xinqiu No. 1. After the cotton plant grows to 5-6 true leaves and spreads flat, remove the main stem growth point of the cotton plant. When three vegetative branches exceeding 5 cm grow in the axils of the true leaves, tr...

Abstract

The invention relates to technology for cultivating three-stem cotton. The technology is characterized by comprising the following steps: shooting growing points on the main stem of a cotton plant after 5 to 6 main leaves growing on the cotton plant are spread; and reshaping the cotton plant when three vegetative shoots over 5cm grow from the axil of the main leaves, removing other residual vegetative shoots, and keeping the three vegetative shoots with similar sizes to become three main stems, secondarily shooting tops of the three main stems and local conventionally cultured spring cotton which is subject to top shooting in the same term. The technology has the advantages of saving man power for management, increasing photosynthesis of the plant, improving the fiber quality, reducing amount of boll rot, increasing the amount of canicular boll, and improving the cotton yield.

Description

technical field [0001] The invention relates to the field of plant planting and cultivation, in particular to the three-stem cotton cultivation technology. Background technique [0002] Conventional insect-resistant cotton in the prior art, artificial pruning and pruning is time-consuming and laborious. The leaves of conventionally cultivated insect-resistant cotton are densely overlapped, and the middle and lower leaves of the cotton plant are seriously shaded from each other, which affects photosynthesis. Less, low output, poor quality. Contents of the invention [0003] The purpose of the present invention is to utilize conventional insect-resistant cotton varieties, take the method of retaining the first three vegetative branches at the bottom of the cotton plant, and cultivate them into three main stems, and conduct a comparative test with conventionally cultivated single-stem cotton, and strive to find out which can reduce the Artificial pruning and pruning of cotto...
