Abstract

A compound fertilizer suitable for rice, wheat, walnut tree, rape and fruit tree is prepared through proportioning raw chemical materials, mixing and stirring. The ratio of N : P : K is (15-20) : (4.5-6.2) : (12-16.5) and their total content is up to more than 36%. It also contains 18 trace elements including Mg, Ca, S, etc. Its advantages are low cost and high effect on increasing yield.

Description

Composite fertilizer

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

For a long time, China's agricultural is in the low yield state always, and per mu yield is not as developed country's height.How to change the present situation that this falls behind? study, explore, manufacture experimently, test, contrast with continuous according to my plantation experience for many years.Find, weather effect is very big to be cultivated the not enough factor with improved seeds except that being subjected to, the chemical fertilizer of being used exactly, the ratio of its contained nutrition be science, rationally not enough, makes farm crop not obtain needed, sufficient nutriment in whole growth process, though so Shi Liaofei, but because the nutrition collocation is unreasonable, fertilizer efficiency is not high, causes malnutrition, so crop growth is bad, output cannot not carried 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 homemade 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.

As the three element compound fertilizer by Russian import, its contained nitrogen (N), phosphorus (P), potassium (K) are though composition respectively accounts for 16%, and to farm crop, N content only has 16% to be not enough, and P content is really too high.

Home-made Xiao Shan composite fertilizer and for example, the composition total amount of nitrogenous (N), phosphorus (P), potassium (K) reach 25%, though the content of P is few, ratio is more suitable, wherein the content of N not enough.The therefore normal phase is used the not high chemical fertilizer of these fertilizer efficiency, and surely not volume increase obtains good harvest.

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 the demand of farm crop to various nutritions fully; And will use according to quantity, could improve output.

The present invention is achieved in that by weight, and powdery composite fertilizer is made in each chemical fertilizer batching thorough mixing, stirring, makes nitrogen in the composite fertilizer: phosphorus: potassium=15-20: 4.5-6.2: 12-16.5 (weight ratio).

And will be according to every mu of hybrid rice (50-60) kilogram, early rice, late rice (45-50) kilogram/mu, the consumption of wheat (30-35) kilogram/mu is used composite fertilizer.

In conjunction with the embodiments the present invention is further described:

Example 1: weigh by weight, the chemical fertilizer batching is: 35 kilograms in urea, 40 kilograms of calcium superphosphate, 25 kilograms in Repone K, with each powdered fertilizer batching thorough mixing, stir and make 100 kilograms of powdered composite fertilizers.

To account for 46.3% be that N content is 35 kilograms * 46.3%=16.2 kilogram to the content of nitrogen in the urea

To account for 13% be that P content is 40 kilograms * 13%=5.2 kilogram to phosphorus content in the calcium superphosphate

To account for 60% be that K content is 25 kilograms * 60%=15 kilogram to the content of potassium in the Repone K

Promptly 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 kilograms of/mu composite fertilizers in soil before rice transplanting, add urea 5-7 kilogram/mu again after crossing two weeks, because of nitrogen content not enough.

Early rice, late rice are used by the consumption of (45-50) kilogram/mu, add urea 2-3 kilogram/mu again behind the two weeks excessively.

Wheat is used by (30-35) kilogram/mu consumption, 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 make 100 kilograms of composite fertilizers with each powdered fertilizer batching thorough mixing.

To account for 46.3% be 39 kilograms * 46.3%=18.1 of N content kilogram to the content of nitrogen in the urea

To account for 13% be that P content is 38 kilograms * 13%=4.94 kilogram to phosphorus content in the calcium superphosphate

To account for 60% be that K content is 23 kilograms * 60%=13.8 kilogram to the content of potassium in the Repone K

Promptly in 100 kilograms of composite fertilizers, nitrogen, phosphorus, potassium, total content reach 36.84%.

Hybrid rice is just put the composite fertilizer of (50-60) kilogram/mu in soil before rice transplanting.

Early, late rice is used by the consumption of (45-50) kilogram/mu.

Wheat is used by the consumption of (30-35) kilogram/mu, just need not enrich urea later on.

The present invention is compared with prior art: because of this composite fertilizer, be according to crops actual institute in growth course The nutrition that needs, the science collocation makes by the nutrition principle, so the effective ingredient of fertilizer is except being rich in Outside nitrogen, phosphorus, the potassium, also contain 18 kinds of trace elements such as magnesium, calcium, sulphur, N, P, K, total content surpasses 36%, Can satisfy crops needed whole nutritions in whole growth period fully, malnutrition can not take place Phenomenon, comprehensive fertilizer efficiency is improved, thus fertilizer efficiency considerably beyond import with domestic composite fertilizer and fertilizer Price only is half of import composite fertilizer.

General farmland can reach 800 kg/acres output at the good good year of weather, weather fine or not right Its impact is very big. Use this fertilizer and then be not subjected to weather effect (except the disastrous weather), through test substantially all Can reach 1300 kg/acres, long because of its spike of rice, in-seam is full, then the output height. Again because of behind its crop fertilization Growth is fast, and not only rice shoot is looked, and the leaf bar is thick, and root is prosperous, the leaf non-lodging, so wind do not fall, disease-resistant Ability is strong, is not afraid of disease and pest, therefore is not subjected to weather effect and the output height.
