Abstract

The invention discloses a light and simple cultivation method for open ground direct seeding of short-season cotton in coastal saline soil. According to the method, high-quality short-season cotton varieties are adopted, and a novel cultivation manner is established by adopting the following measures: watering and building soil moisture, mechanically driving soil to build a seedbed, precise seeding on an open ground, combining a quick-acting fertilizer and a slow release fertilizer for single fertilization, performing chemical top sealing, harvesting cotton in a concentration manner and so on, therefore, on the bases of reducing salt damage and ensuring normal emergence of cotton seedlings and yield formation, the materialization and labor input can be effectively reduced, the pollution caused by pesticides and plastic film residues is reduced, and the comprehensive benefits of cotton planting are improved.

Description

technical field

[0001] The invention relates to a method for cultivating cotton in coastal saline-alkali land, in particular to a method for utilizing short-season cotton in its short growth period and adopting short-season cotton in the open field for late sowing instead of film-covered spring cotton cultivation. Background technique

[0002] Spring cotton varieties are commonly planted in first-ripening cotton fields in the coastal saline-alkali land of the Yellow River Delta. The current cultivation techniques are planting at the right time (mid-to-late April), medium density (about 3,500 plants / mu), mulching with plastic film, manual pruning, and multiple flower harvests. . The disadvantage of this cultivation mode is that: the use of spring cotton varieties in mid-to-late April must be covered with plastic film to increase ground temperature and reduce salt damage, and increase the seeding rate to ensure the seedling rate, but it will easily lead to increased physical a...
