Problems solved by technology

The fertilizer and water management of this method is cumbersome, and it is difficult for farmers to master it. Because the invention adopts a bottomed plastic tray, it affects the downward extension of the cotton seedling root system and the absorption of nutrients. The nutrient area of ​​the root system for seedling cultivation in this method is small, and it is difficult to cultivate strong seedlings; No old paper covering, it is easy to cause slow and uneven seedling emergence or seedling emergence with shells

Abstract

The invention discloses a method for breeding cotton in a small-hole tray with superficial-layer nutrient solution. The method is characterized in that the method comprises the following steps: firstly, compounding peat and perlite in a mass ratio of 2.5-3.5:1.5-2.5 to prepare substrate, arranging the substrate into a small-hole tray and spraying strong seedling and root inducing solution on the surface layer of the substrate; Secondly, sowing cotton seeds into the small-hole tray with a depth of 0.3-0.6cm below the surface of the substrate in the small-hole tray, covering a soaked paper sheet on the surface of the small-hole tray after sowing, and then covering a layer of 0.3-0.6cm thick substrate on the paper sheet; thirdly, lining a double-layer soft plastic gauze pad at the bottom of the small-hole tray and positioning the small-hole tray together with the soft plastic gauze pad into a seed bed; fourthly, after positioning the small-hole tray into the seed bed, using a small arched she for protection, removing the old paper sheet and the articles on the surface thereof when 50 percent of the seeds grow into seedlings, injecting seedling raising nutrient solution into the seed bed with a depth of 1-2cm, and supplementing the nutrient solution in the seed bed in time when being completed evaporated and absorbed; fifthly, protecting the seed bed, and lifting and transplantingthe seedlings after a period of time. The method has the advantages that the cost is reduced, the labor is saved, and the rate of emergence of bred seedlings is high.

Description

technical field [0001] The invention relates to a method for raising cotton seedlings without soil, in particular to a method for raising seedlings with nutrient solution in a shallow layer of a small plug for cotton. Background technique [0002] Since the popularization of the cotton nutrition pot seedling transplanting technology in the 1970s, it has played an important role in improving the quality of cotton and promoting the high yield of grain and cotton. To this day, despite the high labor intensity, labor-intensive time-consuming and low efficiency of transplanting seedlings in nutrient pots, it is still the main method of raising seedlings in the vast cotton areas of the country. In the 21st century, many domestic scientific research units and production units, in order to reduce the labor intensity and cost of cotton seedling cultivation, have conducted in-depth research on the technology of cotton seedling cultivation without soil, and Yang Tiegang, Cotton Oil Cro...
