Problems solved by technology

Coastal saline-alkali land has a large area, high soil salinity, high groundwater salinity and relatively shallow burial depth, especially in low-lying saline-alkali land cotton fields with poor drainage. Difficult to grow seedlings, severe lack of seedlings and severe ridge breakage, slow growth and reduced yield
At present, although the conventional cotton planting method in saline-alkali land has a good effect of reducing or avoiding soil salt damage, it cannot reduce both salt damage and waterlogging damage at the same time, and cannot meet the needs of cotton planting in low-lying waterlogged saline-alkali land

Abstract

The invention discloses a cotton planting method. The cotton planting method comprises the steps that big ridges are formed, land is prepared and turned over to make the ground flat, and centralized fertilizer application is performed at the positions about to serve as ridge tips in the ridge directions; sowing is performed, wherein bunch planting is performed at the end of April to the beginning of May; field management is performed, S-metolachlor is sprayed for weeding from sowing to seedling emergence, topping is performed in the last ten-days period of July, one top and one leaf are picked off for each plant, old leaves of lower portions and middle portions of main stems and leaves in cotton fields in which growth vigor is too strong are removed in batches before and after blossoming; diseases and insect pests are prevented and controlled, wherein acarid insecticides are selected for prevention and control in a red spider high-incidence season, and pyrethrins insecticides are selected for prevention and control in a pink bollworm high-incidence season. By adopting the cotton planting method, the cotton salt damage is effectively relieved, meanwhile water logging damage is also avoided, and the ecological conditions and growing environment of the cotton fields in low-lying water-logging saline and alkaline land are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of planting, in particular to a cotton planting method. Background technique [0002] In order to increase the cotton yield, the cultivation mode of three plants in one hole is often used in production, but the existing cultivation mode only emphasizes three plants in the same hole, and generally three plants are crowded together. The competition between nutrients and water is serious, especially in low- and medium-fertility cotton fields, which will inevitably have a great impact on root growth. Buds and bells fall, and it is not conducive to field management, making it difficult to achieve high-yield goals. [0003] Cotton is an important economic crop on saline-alkali land. For a long time, the exploration of cotton agronomic planting technology in saline-alkaline land has never stopped. At present, there are mainly methods such as flat planting, furrow planting, and furrow planting, whose purpose and f...
