No-tillage water-saving cotton seeding method

Abstract

The invention relates to the field of planting, in particular to a no-tillage water-saving cotton seeding method. The no-tillage water-saving cotton seeding method comprises the steps that (1) ridging and fertilizing are carried out; (2) positions where seeding is carried out are watered, namely, watering is slightly carried out among ridges; (3) herbicide is sprayed and mulching films are paved, namely, after water permeates soil and can not be seen, and the herbicide is sprayed and the mulching films are paved at the same time; (4) hole forming and seeding are carried out, namely, holes are formed in two sides of each mulching film, and cotton seeds are put into the formed holes; (5) substrates are covered, namely, the holes are covered by the substrates after seeding, wherein the substrates comprise 70-75% of fine sand and 25-30% of a grass carbon and perlite mixture. Aiming at the potential risks that hardening can be caused and seedling emergence can be affected because film hole forming and soil covering are popularized in the Yellow River basin, the specific covering substrates for film hole forming and seeding developed according to the no-tillage water-saving cotton seeding method have the advantages of preserving heat, and being ventilative, free of hardening and good in seedling emergence. Meanwhile, because cotton seedling stage disease control drugs are added, seedling stage diseases can be reduced, and the neat and strong seedling effect is achieved.

Description

technical field

[0001] The invention relates to the field of planting, in particular to a no-tillage and water-saving sowing method for cotton. Background technique

[0002] my country has a history of more than 2,000 years of cotton planting, and is one of the countries with a long history of cotton planting in the world. It has now become a major cotton producing country, a major cotton consumer country and a major cotton technology country. Since the founding of the People's Republic of China, my country's cotton varieties and planting techniques have been continuously updated, and the per unit yield of cotton has continued to increase, from 165kg / hm in 1949 2 Increase to the average yield of 1175kg / hm in the first 10 years of the 21st century 2 , Cotton yield increased by more than 6 times.

[0003] At present, my country's cotton cultivation techniques mainly include seedling transplanting technology, film-covered live broadcast technology, and film-covered drip irrig...
