Description

A kind of manufacture method containing Lalgine fertilizer special for cole

Technical field

The present invention relates to a kind of production method of agriculture production fertilizer, specifically a kind of manufacture method containing Lalgine fertilizer special for cole.

Background technology

Rape is that the most general winter crops is planted in the Yangtze valley, the main oil crops of China, long-term cultivated area is at 700 ~ 8,000,000 hectares at present, in the edible vegetable oil of domestic production, about 60% from Semen Brassicae campestris, improving Semen Brassicae campestris output is the important measures meeting people's life requirement, and incorporation of fertilizerin the soil existence is run off, fixing etc. causes the problems such as loss and inefficacy.Therefore, according to the Features of Nutrient Absorption of rape, accomplish science in conjunction with the behavior of various nutritive element in soil, Rational Application is the key point improving fertilizer utilization efficiency, reduce fertilizers input cost, reduce the environmental pollution caused because of fertilizer.

And the way of recommendation of at present rape fertilising to be the nitrogenous fertilizer of 70% ~ 80%, whole phosphate fertilizer, potash fertilizer and boron fertilizer all use when sowing or transplant as base manure, only have remaining nitrogenous fertilizer to be used as to topdress once or twice, and in actual production, also have many peasant planting rapes only to use a base manure.Although rape is very sensitive to nutrient deficiency in seedling stage, but now because increment is little therefore limited to the absorbed dose of nutrient, before rape bolting enters vigorous period, the a large amount of nutrient gaseous state used when base manure volatilizations is with rainwater leaching loss or by soil fixing, and by the time rape is nourished and grown and reproductive growth two most productive period needs often to occur during a large amount of nutrients the phenomenon of fertilizer deficiency, thus affect Semen Brassicae campestris yield and quality.

Summary of the invention

The present invention solves the problem to provide a kind of comprehensive nutrition, fertilizer efficiency the time long and manufacture method containing Lalgine fertilizer special for cole that fertilizer efficiency utilization ratio is higher.

The technical scheme that the present invention adopts for technical solution problem is:

Containing a manufacture method for Lalgine fertilizer special for cole, its production stage is as follows::

Steps A) get the raw materials ready, get the raw materials ready according to following parts by weight proportioning

Urea 30, calcium superphosphate 5, zinc sulfate 2

Monoammonium phosphate 20, zinc oxide 26, boric acid 1

Repone K 16, seaweed extracted liquor 3, marine alga extract residue 40

Described marine alga is the equal proportion mixture of sea-tangle, sargassun, bladder wrack, described seaweed extracted liquor is prepared by the following method, immerse after above-mentioned marine alga is pulverized in the clear water of 1-2 times of weight, be heated to 70-80 DEG C, be 8-8.5 by potassium hydroxide adjust ph, be incubated and stir 30 minutes, adopting 200 order bolting silks to filter after being cooled to normal temperature and obtain first-time filtrate and a filter residue; The clear water getting the weight such as first-time filtrate injects a filter residue, adding sulfuric acid adjust ph while stirring is 2-3, stir 60 minutes, adopt 200 order bolting silks to filter and obtain secondary filtrate and secondary filter residue, first-time filtrate and secondary filtrate equal proportion are mixed to get described seaweed extracted liquor, and secondary filter residue is dried and is marine alga after pulverizing and extracts residue;

Step B) according to as above proportioning, the Repone K of the monoammonium phosphate of the zinc sulfate of the boric acid of the urea of half, half, half, half, the zinc oxide of half and half and whole seaweed extracted liquors are dissolved in 60---in the water of 100 weight parts, obtain granulation slurry;

Step C) by whole calcium superphosphate, marine alga extracts residue and remaining urea, remaining monoammonium phosphate, remaining zinc oxide, remaining boric acid, remaining zinc sulfate, remaining Repone K and remaining urea are pulverized and mixes, and obtains granulation matrix;

Step D) granulation slurry and granulation matrix sent in tablets press to roll be agglomerated into particulate state, then drying, cooling, screening, metering packing, formed described containing Lalgine fertilizer special for cole.

Relative to existing rape fertilizer, what adopt aforesaid method to produce contains Lalgine fertilizer special for cole comprehensive nutrition, and production method is simple, can realize scale operation.In marine alga, specific Sargassum polysaccharides, alginic acid, highly unsaturated fatty acids and multiple natural phant growth regulator, have very high biological activity, can the generation of the nonspecific activity factor in stimulating plant body, regulates Endogenous hormone balance.Fertilizer efficiency utilization ratio is high, and is suitable for the absorption of cole crop, can significantly improve the output of rape, for rape Different growth phases, can provide required nutrient, controls the efficient of fertilizer efficiency, increases economic benefit.

Embodiment

Embodiment 1

A kind of manufacture method containing Lalgine fertilizer special for cole of the present invention, its production stage is as follows:

Steps A) get the raw materials ready, get the raw materials ready according to following parts by weight proportioning
