Abstract
The invention discloses a fertilizer special for long-term slow-releasing houttuynia cordata and a preparation method thereof. The fertilizer comprises the following ingredients of urea, calcium superphosphate, potassium sulfate and inorganic fertilizer additive; and the preparation method comprises the following steps of mixing, smashing, spraying envelop slurry, pelleting and drying. Compared with an existing common fertilizer, the fertilizer special for long-term slow-releasing the houttuynia cordata is a soil testing and formula fertilizer prepared by combining soil nutrient situation according to the nutritive peculiarity of the houttuynia cordata, and through scientific preparation, a long-term slow-releasing nutrient releasing mode is coordinated with houttuynia cordata nutrient uptake, so that the utilization rate of the fertilizer is improved, the fertilizer loss is reduced, the yield of the houttuynia cordata is improved, one-time fertilization for houttuynia cordata production is realized, the labor input for houttuynia cordata production is reduced, and the income of farmers is increased. A novel fertilizer type is provided for a fertilizer market, and the pertinence and the specificity in fertilizer utilization are improved.
Description
Technical field
The present invention relates to fertilizer field, particularly relate to a kind of long-acting slow-release Herba Houttuyniae special fertilizer and preparation method thereof.
Background technology
Herba Houttuyniae (
(Houttuynia cordata unb), another name Herba Houttuyniae, Herba Houttuyniae, hog snout are shouted, dog note ear and stinkweed etc., and various places call differs.For Saururaceae heartleaf houttuynia belongs to per nnial herb, its taste is pungent, cold nature, enters lung channel, has the effects such as clearing heat and detoxicating, the carbuncle that disappears apocenosis, inducing diuresis for treating stranguria syndrome.Herba Houttuyniae is distributed in Central China, the southeast and each provinces and regions, southwest, especially in the majority with provinces such as Guizhou, Sichuan, is a kind of traditional medicinal plant, is again characteristic edible wild herbs among the people, has good comprehensive development and utilization prospect.Herba Houttuyniae is one of definite medicine food dual purpose plant of China Ministry of Health, and it is widely used, determined curative effect, is usually used in treating the diseases such as lung carbuncle, cough due to lung-heat, sore swollen toxin.
Although use in a large number the ultimate production that chemical fertilizer can increase grain, significantly reduced utilization rate of fertilizer, cause the wasting of resources, agriculture production cost increases, and has aggravated environmental pollution.
Summary of the invention
Technical problem to be solved by this invention is that long-acting slow-release fertilizer nutrient release mode and Herba Houttuyniae nutrition absorption are coordinated mutually, improves utilization rate of fertilizer, improves Herba Houttuyniae output, and a kind of long-acting slow-release Herba Houttuyniae special fertilizer and preparation method thereof is provided.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
According to listed as parts by weight, the present invention is by urea 60-66 part, calcium superphosphate 53-70 part, potassium sulfate 45-50 part, adds mineral manure additive spray coated fertilizer preparation and forms.
Preferably, above-mentioned long-acting slow-release Herba Houttuyniae special fertilizer is by 64 parts, urea, 61 parts of calcium superphosphate, 47 parts of potassium sulfate, adds mineral manure additive spray coated fertilizer preparation and forms.
Aforementioned mineral manure additive is borax 0.01-0.05 part, zinc sulfate 0.01-0.03 part, RE microbial fertilizer 0.01-03 part; Coated fertilizer is starch 0.5-1.0 part, glycerine 0.15-0.20 part, formaldehyde 0.20-0.30 part, 100-37H type polyvinyl alcohol (PVA) 0.40-0.52 part.
Further, above-mentioned mineral manure additive is 0.03 part of borax, 0.02 part, zinc sulfate, 0.02 part of RE microbial fertilizer; Coated fertilizer is 0.8 part of starch, 0.18 part of glycerine, 0.24 part, formaldehyde, 0.48 part of 100-37H type polyvinyl alcohol (PVA).
The preparation method of aforementioned long-acting slow-release Herba Houttuyniae special fertilizer: get urea, calcium superphosphate, potassium sulfate and mineral manure additive and mix, pulverize standby; Get starch simultaneously, add water, stir gelatinization in hot water bath, after glycerine, PVA, formaldehyde are mixed, add in starch paste, stirring reaction in hot water bath, obtains coating slurry standby; By mixing, pulverize standby fertilizer, be placed in rotating cylinder preheating, rotating cylinder rotates, and coating slurry is evenly sprayed to drying on fertilizer, is chilled to room temperature, obtains long-acting slow-release Herba Houttuyniae special fertilizer.
Preferably, getting urea, calcium superphosphate, potassium sulfate and mineral manure additive mixes, pulverizes standby; Get starch simultaneously, add 20 parts of water, in 80-90 ℃ of stirred in water bath gelatinizations 20 minutes, after glycerine, PVA, formaldehyde are mixed, add in starch paste, 50-60 ℃ of stirring reactions 1 hour, obtain coating slurry standby; By mixing, pulverize standby fertilizer, be placed in rotating cylinder and be preheated to 75 ℃ of left and right, rotating cylinder turns above rotation by per minute 100, by coating slurry be evenly sprayed on fertilizer through 75 ℃ dry, be chilled to room temperature, obtain long-acting slow-release Herba Houttuyniae special fertilizer.
Slow release fertilizer is in conjunction with modern plants nutrition and fertilization theory and controls release new technology, and consider crop alimentary demand rule, take regulation and control delay or control release period and the burst size of fertilizer nutrient in soil, make its nutrient release mode absorb with crop nutrition content the new-type fertilizer of coordinating or synchronizeing mutually.Release and release control fertilizer has had very big raising than the plant recovery of nutrient of conventional chemical fertilizer, has reduced quantity that nutrient enters farmland ecological environment, has reduced environmental risk.From the development trend of fertilizer science, slow release fertilizer has become the new direction of fertilizer industry development, is the important leverage of modern agriculture harmonious development.
Compare with existing common fertilizer, the Herba Houttuyniae long-acting slow-release special fertilizer of the present invention's development is according to Herba Houttuyniae nutritive property, in conjunction with soil nutrient situation, survey soil formula, and science makes long-acting slow-release fertilizer nutrient release mode and Herba Houttuyniae nutrition absorption are coordinated mutually, improve utilization rate of fertilizer, minimizing loss of chemical fertilizer, improve Herba Houttuyniae output, realize Herba Houttuyniae and produce single fertilization, reduce labour's input that Herba Houttuyniae produces, increased farmers' income.For fertilizer market provides a new fertilizer type, improved specific aim and the specificity of Fertilizer application.
