Description
Technical field
The present invention relates to a kind of paddy rice control release composite fertilizer special and preparation method thereof.
Background technology
Paddy rice is the staple food crop of China, and fertilising is that paddy rice obtains one of important substance basis that increases production.Paddy rice is subjected to weather with fertilizer, and the influence of external factor such as soil simultaneously, more will be examined and take prisoner the objective demand of rice varieties self to nutrition.China is vast in territory, and soil and climatic condition complexity add that rice varieties is various, nutritive property is different, and traditional fertilization of rice is because fertilizer variety is single, and quick-acting is main, be difficult to satisfy different soil, under the weather condition, different rice varieties is to the requirement of fertilizer, therefore, not only fertilizer application frequency is many, and consumption is big, and, because of the fertilizer quick-acting composition of use is many, number of dropouts is big, causes environmental pollution.
Paddy rice is according to early, in, the development characteristics of late rice, different on the demand of nutrition.As early rice Honda 80-90 in the time of infertility days, general late April rice transplanting, harvesting mid-July, nourish and grow and reproductive growth hockets, two seasons early rice generally transplant the back and reached the peak of tillering in 15-20 days, tiller to the absorbed nitrogen in boot stage, phosphorus, potassium nutrition account for and absorb 80% of total amount, and the later stage is 20%.The nitrogen of all kinds of growth period duration of rices, phosphorus, the specific absorption of potassium is roughly 1: 0.5: 0.8.
Traditional early rice not only fertilizer amount is big, the cost height, and it is heavy to work, and a large amount of lavishment inorganic fertilizer also can cause soil compaction, fertilizer loss, degradation detrimentally affect under contaminate environment and the rice quality.Simultaneously, use single chemical fertilizer in a large number, easily cause rice nutrition imbalance, easily lodging, phenomenon such as resistance is low.Therefore, modern scientific nutrition management should possess following condition: the one, carry out the single fertilization on the nutrition regulation; The 2nd, N-P-K in the main nutrient elements and micro-S, Mg's is reasonably combined; The 3rd, the N that runs off easily in soil manual shift plain and the plain composition of K reaches in good time and discharges; The 4th, improve the result of use of chemical fertilizer energetically; The 5th, fertilizer tool land used and the function of increasing soil fertility; The 6th, save labor, be convenient to manually reach characteristics such as machine operation.
Summary of the invention
But the object of the present invention is to provide reasonably two season of a kind of single fertilization, collocation early rice and late rice control release composite fertilizer special and preparation method thereof.
To achieve these goals, technical scheme of the present invention is: a kind of pair season early rice and late rice control release composite fertilizer special, it is characterized in that it is mainly formed by coated urea 40, coated urea S80, ammonium phosphate, dressing vitriolate of tartar S80, vitriolate of tartar, dressing sal epsom S80 and sal epsom feedstock production, the shared weight percent of each raw material is:

The release of coated urea 40 is type linearly, and N is discharged into 40 and reaches 80%, mainly is to satisfy the dressing of turnning green stage in paddy rice early stage and the nitrogen needs before the tillering fertilizer in mid-term.Coated urea S80 discharges and to be nonlinear type, discharges slowly at paddy rice nutrient in early stage, mainly is to satisfy the tillering fertilizer in paddy rice mid-term and the nitrogen needs of the solid fertilizer of heading in later stage.
The release of dressing vitriolate of tartar S80 is nonlinear type, and the release of K is slow early stage, mainly is to satisfy the paddy rice tillering fertilizer and the solid fertilizer of the heading in later stage in mid-term.And potassium sulphate fertilizer mainly is to satisfy the paddy rice dressing of turnning green stage and the plain needs of the potassium before the tillering fertilizer in mid-term in early stage.
The release of dressing sal epsom S80 is nonlinear type, and the release of Mg is slow early stage, mainly is to satisfy the paddy rice tillering fertilizer and the solid fertilizer of the heading in later stage in mid-term.And magnesium sulfate fertilizer mainly is to satisfy the paddy rice dressing of turnning green stage and the plain needs of the magnesium before the tillering fertilizer in mid-term in early stage.
Nitrogen in the fertilizer, phosphorus, the potassium element is a macroelement, and by paddy rice grows essentially, and fertiliser containing magnesium and sulfur fertilizer can improve the photosynthetic efficiency of paddy rice, and the output of raising paddy rice is improved the quality of paddy rice.
The present invention is the dressing of turnning green stage in early stage according to paddy growth cycle and required nutrient difference, the tillering fertilizer in mid-term, the solid fertilizer of the heading in later stage.The dressing of turnning green stage in early stage, mainly by coated urea 40 (claiming controlled release nitrogenous fertilizer again), ammonium phosphate, sulphate of potash and magesium go to finish, and the tillering fertilizer of middle and later periods and the solid fertilizer of earing are mainly by coated urea S80, and dressing vitriolate of tartar S80 and dressing sal epsom S80 go to finish.Mg and S fertilizer help the quality that improves setting percentage and improve rice.
Problem such as the invention solves that traditional chemical fertilizer utilizes weak effect in using, environmental pollution is heavy and NPK is out of proportion, the present invention each moiety N, K, Mg and S are controlled, N, P, K, Mg and S collocation rationally, high-content Mg and S are applicable to two season early rice and late rice.Carry out the single fertilization method, single fertilization season is in the late April of early rice transplanting date, and on the June of single cropping late rice transplanting date 20, on the July of late rice transplanting date 20, its using method is to do all that base manure is disposable to be broadcasted sowing under rice shoot.Dressing 40, dressing S80 Wholly-degradable that the present invention uses.
The invention has the beneficial effects as follows: the one, the fertilising several times a year of modify-water rice has reduced labour cost and activity duration for property fertilising annually; The 2nd, reduced the serious problem of bringing because of repeatedly applying fertilizer of liquid manure loss; The 3rd, according to rice crop to N and K fertilizer year demand characteristics, carry out N and K fertilizer in good time and reasonably regulation and control, meet and paddy rice boot stage divide the rule of absorption demand N element and K attainment, reach the purpose that applies fertilizers scientifically; The 4th, reasonably arrange in pairs or groups N, P, K and Mg, S content help improving light and the performance of crop, improve rice matter and resistance.
Using method:
Early rice can have effect composition 9-10 kilogram by every mu of N, and double cropping late rice have by every mu of N imitates 10 kilograms of compositions, and the single cropping late rice have the standard of imitating 12 kilograms of compositions by every mu of N, converses the rate of fertilizer application of above-mentioned fertilizer required on the soil of unit surface.Again by seed sower or manually behind rice transplanting, be sprinkled into the land for growing field crops as disposable base manure.
