Abstract

The invention relates to a special nutrient set of fertilizer for cotton, which comprises 15-25 parts of fertilizer for grow seedlings, 25-40 parts of fertilizer for permanent planting and 40-55 parts of dressing fertilizer, wherein the fertilizer for the grow seedlings is composed of grass carbon, calcium superphosphate, zinc sulfate, boric acid and a chelate iron fertilizer; the fertilizer for the permanent planting is composed of a humic acid controlled release nitrogenous fertilizer, a phosphatic fertilizer and a potash fertilizer; and the dressing fertilizer is composed of a nitrogenous fertilizer and a potash fertilizer. The special nutrient set of fertilizer for the cotton in the invention reasonably collocates the fertilizer required by each growth stage, thereby solving blindnessof selecting the fertilizers for peasants, preventing spindling of the cotton at the seedling stage, releasing the nutrient slowly and stably and improving utilization ratio of the fertilizer.

Description

technical field [0001] The invention relates to a special fertilizer for cotton, in particular to a nutritional package fertilizer which is composed of seedling raising fertilizer, planting fertilizer and topdressing fertilizer and can meet the nutrient requirements of cotton throughout the growth period, and belongs to the technical field of fertilizer production. Background technique [0002] Scientific fertilization is one of the important measures to obtain high yield of cotton. Cotton needs a variety of nutrients during the growth process. Since the nutrients in the soil are limited, these nutrients need to be supplemented in a timely and reasonable manner according to the soil conditions and cotton needs in order to obtain high and stable yields. However, the absorption of nutrients by cotton has its own rules. Different growth stages absorb different amounts of various elements, and the same growth stage absorbs different nutrients. At the same time, there are proble...
