Abstract
The invention provides an ecological fertilizer special for rice and an application process of the fertilizer, and belongs to the technical field of fertilizers. The ecological fertilizer special for rice comprises a basal-tillering fertilizer and a panicle-spikelet fertilizer. The application process comprises the following steps of: applying 45-55kg of basal-tillering fertilizer to each Mu of paddy field in three times from the seeding time to the tillering stage; and applying 15-25kg of panicle-spikelet fertilizer to each Mu of paddy field in the panicle differentiation stage. The ecological fertilizer provided by the invention is designed according to the growth characteristic and the fertilizing need characteristic of rice through adjusting the ratio of major elements N (nitrogen), P (phosphorus) and K (potassium) and adding chemicals such as rice growth specific microelements and an anti-nitrification inhibitor, the demands of major nutrient elements and microelements of rice in whole growth stage are met, and meanwhile, the purpose of increasing both yield and income is fulfilled by increasing the fertilizer efficiency and the fertilizer use ratio. The application process provided by the invention is designed according to two fertilizer-needing peak periods in the growth of rice; the application process is scientific and reasonable; and by using the application process, the fertilizer can be conveniently absorbed by rice, and meanwhile, the application cost is reduced.
Description
Technical field
The invention belongs to technical field of fertilizers, be specifically related to ecological special-purpose fertilizer of paddy rice and application process thereof.
Background technology
Conventional fertilizers exists serious blindness and waste problem in using.The experience of often using with the peasant of fertilizer is main, and this also is to cause one of China's utilization rate of fertilizer reason of lower.China's utilization rate of fertilizer N fertilizer is 35%, and P fertilizer is 15%, and K fertilizer is 40%, far below developed country.Except utilization rate of fertilizer lowly, common fertilizer also exists the excessive problem of using.Excessive loss in the system of farmland to fertilize can cause body eutrophication and atmosphere Greenhouse effect.Therefore, how to improve utilization rate of fertilizer effectively, add the technology content of large chemical fertilizer, develop the key subjects that efficient, free of contamination plant growth dedicated fertilizer has become the modern agriculture scientific research.
The special-purpose fertilizer of paddy growth is to prepare according to the physiological requirements of paddy rice, and nutritive elements such as nitrogen phosphorus potassium and middle trace element are carried out the granulated fertilizer that scientific matching is processed.It has organic-inorganic combination, long-acting quick-acting combinations, major element and micro-bonded characteristics, reaches high yield, high-quality, the polynary action effect of synergic.Two need fertile peak period, tillering phase and boot stage arranged in paddy rice fertility.Paddy rice is if want high yield, growth answers that individual growth is vigorous early stage, well developed root system, tiller fast, the leaf look dark green, colony is bigger, has established high yield seedling frame; Grow mid-term, require rice straw slightly strong strong, population growth is neat, and the leaf look dark green; After the heading, the fringe head is neat, and grouting is fast, full seed, the blade Huang that in good time falls, blue or green bar yellow maturity.Research shows that whenever producing 500 kilograms of paddy needs absorbed nitrogen 10-12 kilogram approximately, phosphorus 4-6 kilogram, potassium 11-14 kilogram.In addition, boron, zinc etc. also is the essential element of paddy growth, and different times, the nutrient demand of paddy rice is had nothing in common with each other again.Generally speaking, repeatedly/split application can effectively improve fertilizer utilization efficiency, but gradation/consumption worker not only consuming time repeatedly applies fertilizer; And in peasant's actually operating; Can't therefore often occur " one bombards " targetedly according to rational proportion concentration of fertilizer breeding time, disposable executing weighs fertilizer; Execute problems such as unicity fertilizer the time of infertility, thereby caused the waste and the pollution of fertilizer.
Summary of the invention
Problem to the prior art existence; The objective of the invention is to design the technical scheme that ecological special-purpose fertilizer of paddy rice and application process thereof are provided, this paddy rice is ecological special-purpose fertile in the growth period duration of rice setting, and scientific formulation is reasonable; Can make paddy rice reach high yield, high-quality, the polynary action effect of synergic; And this application process is scientific and reasonable, has practiced thrift and has used cost, has improved paddy rice and has absorbed efficient.
Described paddy rice is ecological special-purpose fertile; It is characterized in that comprising basic fetilizer for tillering and ear manuer, described basic fetilizer for tillering is made up of the component of following weight per-cent: urea 29～41%, monoammonium phosphate 15～19%, Repone K 13～23%, zinc sulfate 2～5%, borax 2～5%, anti-nitrification inhibitor 2～5% and fertilizer stopping composition 10～36%; Described ear manuer is made up of the component of following weight per-cent: urea 32～47%, Repone K 36～47%, borax 2～8% and fertilizer stopping composition 0～30%.
