Abstract

The present invention relates to a special-purpose fertilizer formula for cotton seedling bed. Said special-purpose fertilizer is made up by using main nutrient elements of nitrogen, phosphorus and potassium, microelements of copper, zinc, iron, manganese and boron and plant growth accelerating, regulating and controlling agent trough a certain preparation process. Said special-purpose fertilizer can be made into solid or liquid fertilizer, and can be mixed with pure gibberellic acid and mepiquat chloride so as to obtain a mixed formula fertilizer.

Description

technical field [0001] The invention belongs to a special fertilizer for raising seedlings by floating in cotton water body seedbeds, and in particular relates to the material composition and ratio, preparation method, use and scope of application of the special fertilizer. Background technique [0002] At present, there are two kinds of cotton seedling raising methods, one is matrix seedling raising, such as Yang Tiegang of Henan Academy of Agricultural Sciences (cotton factory seedling raising technology and its high-yield and high-efficiency technical regulations [J]. Henan Agricultural Science, 2003 (9): 23- 24) The established matrix seedlings have achieved a survival rate of more than 95% after transplanting cotton seedlings without soil and a slow seedling period of 5-7 days (shorter than the nutrient pot), and also realized that cotton seedlings can still be stored indoors for 3 days. The ideal goal of the above indicators; Mao Shuchun (new progress in the research o...
