Problems solved by technology

[0003] At present, the sowing time of spring cotton in the Yellow River Basin is generally from late April to early May, and the proportion of late autumn peaches on the top and periphery of cotton plants is large. At present, the method of spraying ripening agents is mostly used in production to promote the opening and timely harvest of late autumn peaches, but this is not the case. This traditional method leads to a decrease in cotton yield and quality, and common cotton diseases are more serious

Abstract

The invention discloses a cotton early sowing fertilizer and an early sowing method, and belongs to the technical field of cotton cultivation. The cotton early sowing fertilizer is prepared from straw powder, decomposed bacteria and urea and applied to the field, in cooperation with the early sowing method, the soil temperature can be increased, sowing is conducted in advance, the boll opening time of cotton is prolonged, the cotton yield is increased, and diseases and insect pests are effectively prevented and controlled.

Description

technical field [0001] The invention belongs to the technical field of cotton cultivation, and in particular relates to a cotton early-sowing fertilizer and an early-sowing method. Background technique [0002] Cotton is the seed fiber of Malvaceae (Gossypium) plants. It is native to the subtropical zone and is one of the most important crops in the world. It has large yield and low production cost, making cotton products relatively cheap. Cotton fiber can be made into fabrics of various specifications, from light and transparent voile to thick canvas and thick velveteen, suitable for making all kinds of clothes, furniture cloth and industrial cloth. Ironed at high temperatures, the cotton fabric is comfortable to wear due to its quick absorption and release of moisture. [0003] At present, the sowing time of spring cotton in the Yellow River Basin is generally from late April to early May, and the proportion of late autumn peaches on the top and periphery of cotton plants...
