Abstract
The invention belongs to the technical field of plant cultivation and relates to a special controlled release blended fertilizer for sisal hemps. The special controlled release blended fertilizer is prepared by uniformly mixing a nitrogen fertilizer, a phosphate fertilizer and a potash fertilizer, and the nitrogen fertilizer is urea comprising general urea, polymer coated controlled release urea released in 80-100 days and polymer coated controlled release urea released in 140-160 days. According to the special controlled release blended fertilizer, the process is simple, and the nitrogen fertilizer, the phosphate fertilizer and the potash fertilizer are organically combined to enable the supply of the urea to meet the requirements of the sisal hemps on nutrients in time, so that the disadvantages of excessive nitrogen supply in earlier stage and insufficient nitrogen supply in later stage after a large amount of high-nitrogen chemical fertilizers are applied at a time are effectively avoided, the utilization rate of the fertilizers is increased, the production cost is reduced, and an effective solution is provided for the scientific fertilizer application of the sisal hemps in our nation. Therefore, the special controlled release blended fertilizer has the advantages of higher practical value and wide market prospect.
Description
Technical field
The invention belongs to field of plant growing technology, relate to a kind of fertilizer, the dedicated release-controlled Bulk Blending Fertilizer of particularly a kind of sisal hemp of sisal hemp single fertilization.
Background technology
Guangdong, Guangxi, Hainan and Fujian are the topmost producing regions of China sisal hemp.Conventional fertilization mode is respectively to apply fertilizer once in annual April and September.In recent years, because the rural laborer shifts, the recruitment cost is too high, adds that sisal hemp fertilizer machinery degree is not high, fertilising difficulty etc., so the peasant generally adopts single fertilization.Single fertilization is meant in annual April, applies greatly in the ranks the fertilizing method that fertilization depth 20-40cm, other times do not refertilize to the fertilizer (being high nitrogen chemical fertilizer mostly) in 1 year once.
In recent years, the sisal hemp single fertilization is commonplace, and high nitrogen chemical fertilizer has become the main body in market.But disposablely use high nitrogen chemical fertilizer in a large number and be prone to cause root district nutrient density too high in earlier stage, be prone to " burning seedling " phenomenon; Also very easily cause ammonia loss by volatilization, reduce nitrogen utilization efficiency; Later stage is prone to cause the confession nitrogen hunger, is prone to " denitrogenation " phenomenon; Nitrogen in the various fertilizer of selling at present on the market simultaneously, phosphorus, potassium nutrition proportioning are improper, cause utilization rate of fertilizer not high.However, simplify the needs of production operation because single fertilization has satisfied the peasant, so need to satisfy sisal hemp high yield needs, improve plant recovery of nutrient according to the existing fertilizer performance of production need for improved.
Nutrient resource integrated management theory and technology according to " nitrogen is monitored in real time, phosphorus potassium constant monitoring "; The supply of nitrogen in time should be consistent to nutrient demand with sisal hemp; Can realize through two kinds of approach, the one, split application nitrogenous fertilizer, the 2nd, utilize modern controlled-release technology to process dedicated release-controlled nitrogenous fertilizer as requested; According to phosphorus potassium constant monitoring technique thinking, phosphorus, potassium application rate can be confirmed according to fertilization area available phosphorus, potassium content.
Summary of the invention
The purpose of this invention is to provide the dedicated release-controlled Bulk Blending Fertilizer of a kind of sisal hemp; Nitrogenous fertilizer, phosphate fertilizer, potash fertilizer are organically combined, can realize that the supply of nitrogen is consistent to nutrient demand with sisal hemp in time, avoid disposable effectively and use high nitrogen chemical fertilizer in a large number and supply nitrogen too much in earlier stage; Later stage supplies the drawback of nitrogen hunger; Improved fertilizer utilization ratio, reduced production cost, for applying fertilizers scientifically of China sisal hemp provides an effective solution route.
The technical scheme that the present invention adopted:
The dedicated release-controlled Bulk Blending Fertilizer of a kind of sisal hemp is that nitrogenous fertilizer, phosphate fertilizer and potash fertilizer are mixed and makes, and its ratio of weight and number is: 10～18 parts in nitrogenous fertilizer, 5～8 parts in phosphate fertilizer, 20～24 parts in potash fertilizer; Said nitrogenous fertilizer is urea; Polymer coated controlled release urea by common urea, the polymer coated controlled release urea that discharged in 80～100 days and release in 140～160 days is formed; Its ratio of weight and number is: common urea: the polymer coated controlled release urea that discharged in 80～100 days: polymer coated controlled release urea=8～12:2～6:4～8 that discharged in 140～160 days are preferably 10:4:6.
In the dedicated release-controlled Bulk Blending Fertilizer of above-mentioned sisal hemp, the ratio of weight and number of said each component is preferably: 14 parts in nitrogenous fertilizer, 7 parts in phosphate fertilizer, 22 parts in potash fertilizer.
In the dedicated release-controlled Bulk Blending Fertilizer of above-mentioned sisal hemp, said phosphate fertilizer can be selected from monoammonium phosphate, diammonium phosphate, superphosphate of lime, double superhosphate and the fused(calcium magnesium)phosphate one or more.When phosphate fertilizer is the compound of above-mentioned multiple phosphate fertilizer, can carry out matched combined based on actual conditions, adding proportion can be selected arbitrarily.
In the dedicated release-controlled Bulk Blending Fertilizer of above-mentioned sisal hemp, said potash fertilizer can be vitriolate of tartar or Repone K, when potash fertilizer is the mixture of above-mentioned two kinds of potash fertilizer, can carry out matched combined according to practical situation, and adding proportion can be selected arbitrarily.
Technology of the present invention is simple; Problem to the existence of sisal hemp single fertilization; Nutrient resource integrated management theory and technology according to " nitrogen is monitored in real time, phosphorus potassium constant monitoring " according to sisal hemp nutrient demand characteristics and soil nutrient characteristic, adopts the urea of different rates of release to be mixed; Realize the synchronous of nitrogen demand and supply, have following advantage is arranged:
1) two kinds of control release ureas that release period is different have been added; Form three grades of releases of urea to satisfy the yearly demand of sisal hemp to nitrogen; The centre need not impose nitrogenous fertilizer; Thereby can effectively guarantee the supply of sisal hemp growth later stage nitrogen, avoid common high nitrogen chemical fertilizer to supply nitrogen too much in earlier stage, the later stage supplies the drawback of nitrogen hunger.
2) according to the supply situation of nitrogen, phosphorus, potassium nutrition in the sisal hemp garden mould earth, sisal hemp is confirmed nitrogen, phosphorus, potassium nutrition proportioning to demand and a large amount of field fertilizer test result of nitrogen, phosphorus, potassium nutrition, and nutrient balance is used, and has improved fertilizer utilization ratio.
3) the similar relatively slow controlled release product of production cost is lower, and common relatively high nitrogen Bulk Blending Fertilizer cost only increases about 80 yuan, and utilization rate of nitrogen fertilizer on average improves 4.0%, help the peasant the saving of labor, increase production and increase income.
The present invention applies fertilizers scientifically for China sisal hemp, and the raising of utilization rate of fertilizer provides an effective solution route, has higher utility, and market outlook are wide.
