Abstract

The invention relates to a special compounded fertilizer for wheat in a lime concretion black soil area and an environment capacity considered application method. The special compounded fertilizer consists of the following raw materials: 22.0-31.0% of large granular urea, 18.0-29.0% of controlled release urea, 27.0-32.0% of monoammonium phosphate, 13.0-17.0% of potassium chloride or potassium sulfate, 3.0-6.0% of organic matter auxiliary materials and 1.0-2.0% of micro element fertilizers. The special compounded fertilizer can be used as both a base fertilizer and a topdressing fertilizer when being used. The special compounded fertilizer for wheat, which is provided by the invention, is scientific in formula, is specially used for cultivating and planting wheat in the lime concretion black soil area, is capable of meeting requirements of wheat on nutrients to grow and develop and is easy in raw material obtaining and simple in machining process, and both industrialized production can be achieved and requirements of farmers on soil testing and formulated fertilization.

Description

technical field [0001] The invention belongs to the technical field of agricultural soil fertilizers, and in particular relates to a special compound fertilizer for wheat in Shajiang black soil area and an application method taking into account the environmental capacity. Background technique [0002] Wheat is an important food crop planted in a large area in my country, and the yield level of wheat directly affects my country's food security. The proportion of agricultural production materials required in the whole growth period of wheat is the highest among all agricultural production materials, especially the proportion of wheat fertilizer application in the whole crop fertilizer application is the largest. The growth period of wheat is longer, and the requirements for nutrients tend to be more long-term nutrients. Driven by the national policy of "one control, two reductions and three basics", blindly increasing the amount of fertilizer to increase crop yield can no lon...
