The calcium magnesium phosphate fertilizer provided by the invention has complete nutrients, multiple functions, high comprehensive fertilizer effect and high yield-increasing potential, can improve the physical and chemical state of soil, combines quick action and slow action and realizes integrated water/fertilizer regulation and control.
Description
Technical field
The present invention relates to a kind of compound calcium magnesium-phosphorus fertilizer that is applicable to farm crop.
Background technology
China is one of country of fertilizer amount maximum, the cultivated area that accounts for the whole world 8% but uses approximately 30% chemical fertilizer amount, since excessive or irrational partially to fertilize, cause nutritive props imbalance in the soil, input-output ratio descends, strengthened production cost, agricultural-food descend, soil compaction aggravation, beneficial microorganism group is by subtracting, too much consumption chemical fertilizer raw material resource and the energy, loss of chemical fertilizer has caused the surface water oxygen enrichment, Nitrate content in ground water raises, and agroecological environment worsens, and affects the problem such as people's physical and mental health and has caused the concern of relevant department and the whole society.
Standard according to international food quality and security is divided into pollution-free food with food quality and safety, green food and Organic food, and the standard according to China's food quality and safety is divided into pollution-free food with food quality and safety.A level (secondary) green food, AA level (one-level is international Organic food) green food.Aspect Fertilizer application, produce A level (secondary) green food, allow to use on a small quantity or partly use chemical fertilizer such as urea, monoammonium phosphate, diammonium phosphate, vitriolate of tartar, production AA level (one-level) green food, the inaccurate chemical fertilizer that uses any synthetic, can only manure use material, bio-feritlizer and some natural mineral fertilizer.
Compound calcium magnesium-phosphorus fertilizer of the present invention is to solve the required nutritional requirement of crop by using mineral manure, substitute and reduce the consumption of chemical fertilizer, by the slowly-releasing regulation and control factor in the product, the release rate of control fertilizer, slow down because dissolving fast and run off and lost efficacy by soil fixing, make nutritive element fertile requirement accomplish " discharging as required " or " as required supply " according to the need of crop, thereby overcome the contradiction that fertilizer dissolves fast and crop slowly absorbs, improved the utilization ratio of fertilizer, reduced number of dropouts, alleviate the pollution of water source edatope, meet the requirement of energy-saving and emission-reduction environmental protection.
Summary of the invention:
The object of the invention is to provide a kind of compound calcium magnesium-phosphorus fertilizer, to have added porphyritic monzonitic granite or medical stone on the basis of existing fused(calcium magnesium)phosphate, Sodium salts humic acids or humic acids, urea, sodium polyacrylate, poly-aspartic-acid, the rare earth nitrate surplus is made, this compound calcium magnesium-phosphorus fertilizer is that a kind of nutrition is complete, function is many, and comprehensive fertility is high, and yield potential is large, can improve soil physical and chemical property, alleviate soil compaction, increase soil fertility, purify edatope, quick-actingly combine the integrated fertilizer variety of water-fertilizer conditioning with slow.
