Abstract

The invention discloses a compound fertilizer suitable for being applied to farm crops, such as hybrid rice, early rice, late rice, wheat, Chinese chestnuts, rapes and fruits. The powdery compound fertilizer is prepared by sufficiently mixing and stirring various fertilizer ingredients at a weight ratio, wherein the ratio of nitrogen, phosphorus and kalium in the compound fertilizer is equal to (15-20):(4.5-6.2):(12-16.5), and the total content of nitrogen, phosphorus and kalium is more than 36%, and the compound fertilizer also contains 18 trace elements such as magnesium, calcium and sulfur and is necessarily used for the hybrid rice according to the condition of (50-60) kilograms/mu, the early rice and the late rice according to the condition of (45-50) kilograms/mu and the wheat according to the condition of (30-35) kilograms/mu for one time. The compound fertilizer disclosed by the invention is prepared by scientifically collocating nutrition ingredients actually required by the farm crops in the growing process according to a nutriology principle, can be used for increasing the output and is low in price.

Description

Composite fertilizer

Technical field

The present invention relates to a kind of composite fertilizer, suitable especially hybrid rice, early, the composite fertilizer that uses of the farm crop such as late rice, wheat and Chinese chestnut, rape, fruit.

Background technology

For a long time, China's agricultural is in the low yield state always, and per mu yield is high not as developed country.How to change the present situation that this falls behind? according to my plantation experience for many years and constantly research, explore, trial-production, test, contrast finds, weather effect is very large to be cultivated the inadequate factor with improved seeds except being subjected to, the chemical fertilizer of using exactly, the ratio of its contained nutrition is science, reasonable not enough, make farm crop in whole process of growth, not obtain needed, sufficient nutriment, though so Shi Liaofei, but because nutrition collocation inconvenience reason, fertilizer efficiency is not high, cause malnutrition, so crop growth is not, output cannot not carry highly certainly.

The another one reason is exactly the amount of application of chemical fertilizer, and the user does not grasp, because no matter be import fertilizer, or domestic fertilizer, all do not tell the user on the working instructions, how many chemical fertilizer every mu of ground of different farm crop should use.Therefore the user just goes with the flow, and arbitrarily uses, and fertilizer is executed very little, does not have effect at all, and Ruo Shide is too many, and not only waste does not reach the purpose of volume increase yet.

Summary of the invention

The object of the present invention is to provide a kind of composite fertilizer, efficiently solve farm crop desired nutritional unbalanced supply-demand state, and the fertilizer proportioning components rationally, effectively, can satisfy farm crop fully to the demand of various nutritions, and will use according to quantity, could improve output.

The present invention is achieved in that by weight, and each chemical fertilizer batching is fully mixed, stirred and make powdery composite fertilizer, makes nitrogen in the composite fertilizer: phosphorus: potassium=15～20: 4.5～6.2: 12～16.5 (weight ratios).

And will be according to hybrid rice (50～60) kg/acre, early, late rice (45～50) kg/acre, the consumption of wheat (30～35) kg/acre is used composite fertilizer.

Embodiment

The invention will be further described in conjunction with the embodiments:

Example 1: weigh by weight, chemical fertilizer batching is: 35 kilograms in urea, 40 kilograms of calcium superphosphate, 25 kilograms in Repone K, each powdered fertilizer batching is fully mixed, and stir 100 kilograms of the composite fertilizers of making powdery.

The content of nitrogen accounts for 46.3% in the urea, and namely N content is 35 kilograms * 46.3%=16.2 kilogram

Phosphorus content accounts for 13% in the calcium superphosphate, and namely P content is 40 kilograms * 13%=5.2 kilogram

The content of potassium accounts for 60% in the Repone K, and namely K content is 25 kilograms * 60%=15 kilogram

Namely in 100 kilograms of composite fertilizers, the total content of nitrogen, phosphorus, potassium reaches 36.4%.

During use, be according to the consumption standard of different crops, disposable employed composite fertilizer.

Hybrid rice is just put 50 kg/acres of composite fertilizers in soil before rice transplanting, add 5～7 kg/acres in urea after crossing two weeks again, because of nitrogen content not enough.

Early, late rice uses by the consumption of (45～50) kg/acre, adds 2～3 kg/acres in urea after crossing two weeks again.

Wheat is used by the consumption of (30～35) kg/acre, does not need to have executed urea again.

Example 2: weigh by weight, 39 kilograms in urea, 38 kilograms of calcium superphosphate, 23 kilograms in Repone K fully mix each powdered fertilizer batching, make 100 kilograms of composite fertilizers.

The content of nitrogen accounts for 46.3% in the urea, and namely N content is 39 kilograms * 46.3%=18.1 kilogram

Phosphorus content accounts for 13% in the calcium superphosphate, and namely P content is 38 kilograms * 13%=4.94 kilogram

The content of potassium accounts for 60% in the Repone K, and namely K content is 23 kilograms * 60%=13.84 kilogram

Namely in 100 kilograms of composite fertilizers, the total content of nitrogen, phosphorus, potassium reaches 36.84%.

Hybrid rice is just put (50～60) kg/acre composite fertilizer in soil before rice transplanting.

Early, late rice is used by the consumption of (45～50) kg/acre.

Wheat is used by the consumption of (30～35) kg/acre, just need not enrich urea later on.

The present invention is compared with prior art: because of this composite fertilizer, according to farm crop actual needed nutrition in process of growth, the science collocation makes by the trophology principle, therefore the effective ingredient of fertilizer is except being rich in nitrogen, phosphorus, outside the potassium, also contain magnesium, calcium, 18 kinds of trace elements such as sulphur, N, P, the K total content surpasses 36%, can satisfy farm crop needed whole nutritions within whole vegetative period fully, underfed phenomenon can not occur, comprehensive fertilizer efficiency is improved, so fertilizer efficiency is considerably beyond import and domestic composite fertilizer, and the price of fertilizer only is half of import composite fertilizer.

General farmland can reach 800 kg/acres of output at the good good year of weather, and the quality of weather is very large on its impact.Use this fertilizer and then be not subjected to weather effect (except the diastrous weather), substantially all can reach 1300 kg/acres through test, long because of its spike of rice, in-seam is full, and then output is high.To execute rear growth fast because of its crop again, and not only rice shoot is looked, and the leaf bar is thick, and root is prosperous, the leaf non-lodging, so wind is not fallen, resistance against diseases is strong, is not afraid of disease and pest, therefore is not subjected to weather effect and output is high.
