Description
Technical field
The invention belongs to agriculture clay fertilizer technical field, be specifically related to the special-purpose fertilizer of a kind of high-yield corn.
Background technology
Fused(calcium magnesium)phosphate is alkaline fertilizer, must execute competence exertion fertilizer efficiency on acid soil, and application effect is poor on alkaline soil.Shajiang black soil is calcareous soil, before the eighties in last century, between the soil general pH value 7.2～8.6, it is alkaline soil, phosphate fertilizer is mainly selected phosphate fertilizer such as acid calcium superphosphate and phosphorus ammonium for use, and alkalescence, solubility in citric acid fused(calcium magnesium)phosphate are considered to do not have effect at Shajiang black soil, use hardly.The Shajiang black soil available phosphorus content is low, be lower than 5mg/kg mostly before the phosphorus to fertilize in a large number, phosphate fertilizer is the gordian technique that this soil improves crop yield, along with chemical fertilizer phosphate fertilizer is used in a large number, the Shajiang black soil available phosphorus promotes significantly, be 4.8mg/kg as Mengcheng County, Anhui in 1985 soil available phosphorus average content, available phosphorus content had reached 16.3mg/kg in 2002, the soil available phosphorus fast lifting has improved soil fertility, but also increased the loss risk, it is relevant that a lot of rivers, Shajiang black soil district eutrophication and soil available phosphorus content significantly increase, and the friendly type phosphate fertilizer of efficient context technology is the Shajiang black soil urgent problem.Because chemical fertilizer is used and acid rain etc. in a large number, the general acidifying of soil, Shajiang black soil has obvious acidification trend too.Show according to 2009～2010 years Shajiang black soil test analysis in Mengcheng County, the whole county slightly acidic soil of topsoil soils pH value between 5.5～6.5 accounts for 45.01%, topsoil soils pH value accounts for 3.74% less than 5.5 acid soil, uses for the Shajiang black soil fused(calcium magnesium)phosphate to create conditions.
Summary of the invention
In order to improve the output of Shajiang black soil maize planting, it is special-purpose fertile to the invention provides a kind of high-yield corn for Shajiang black soil.
The special-purpose fertilizer of high-yield corn that is used for Shajiang black soil is made up of with topdressing base manure, and wherein base manure is made up of A component and B component; Topdress and be urea;
