Abstract

The invention discloses a special grass meal fertilizer for seedlings. The special grass meal fertilizer for seedlings comprises the following active ingredients in parts by weight: 400-450 parts of grass meal, 30-40 parts of mud, 35-40 parts of diatomaceous earth, 30-35 parts of calcium superphosphate, 30-35 parts of calcium magnesium phosphate, 12-15 parts of urea, 12-14 parts of potassium chloride, 10-12 parts of ammonium chloride, 1-2 parts of potassium permanganate, 6-9 parts of EM (Effective Microorganisms), 10-15 parts of soil conditioning agent, and a proper amount of water. According to the fertilizer adopting grass meal as a main active ingredient, the nutrient elements in different growth periods of the seedlings can be absorbed in a balanced manner so as to achieve the supplementation of elements in different growth periods, the loss of nutrient elements can be reduced, no harm to the root system exists, the fertilizer effecting period is long, and the fertilizer utilization rate is high. In addition, the added diatomaceous earth is fine and smooth, loose, light-weight, porous, and strong in water absorption property and permeability, and the like, and can achieve the effects of preserving moisture, loosening soil, prolonging the pesticide effect and fertilizer effect time, and helping growth of fruit trees in soil.

Description

Special-purpose grass meal fertilizer of a kind of nursery stock and preparation method thereof

Technical field

The present invention relates to a kind of technical field of fertilizers, particularly special-purpose grass meal fertilizer of a kind of nursery stock and preparation method thereof.

Background technology

Nursery stock initial stage new root is slow, and the ability of obtaining nutrient from soil is lower, and it survives and grow and mainly depends on interior transfer and the reallocation of storing nutrient in body.Therefore,, in the cultivating process of nursery stock, giving and be very important of seedling-nourishing, is very important, is also the key of dealing with problems and give with fertilizer nutrition and energy by nursery stock fertilizer.

In present fertilizer, forestry fertilizer take grass meal fertilising with technique of balanced fertilizer as basis, be rich in the multiple elements such as N, P, K, Zn, Fe, Mn and organic matter, humic acids.But the utilization ratio of the fertilizer of China is but very low, the rate of loss of potash fertilizer reaches more than 20%, has not only strengthened production cost, also to peasant, has brought loss economically; Due to a large amount of inorganic potassium fertilizer of using, cause soil compaction, crop production reduction, ecotope to suffer destruction, particularly body eutrophication, affects human and livestock health.

Summary of the invention

Fertilizer object of the present invention is to provide special-purpose grass meal fertilizer of a kind of nursery stock and preparation method thereof.

Technical scheme of the present invention is as follows:

Fertilizer is made by the raw material of following weight part: grass meal 400-450, earth 30-40, diatomite 35-40, calcium superphosphate 30-35, fused(calcium magnesium)phosphate 30-35, urea 12-15, Repone K 12-14, ammonium chloride 10-12, potassium permanganate 1-2, EM microbial inoculum 6-9, soil conditioner 10-15, water are appropriate;

Described soil conditioner is made by the raw material of following weight part: weathered coal 120-130, bamboo charcoal 24-30, nanometer jade powder 3-4, borax 1-2, nano-calcium carbonate 2-3, peat composed of rotten mosses 10-12, boric acid 2-3, dry pine needle powder 9-12, neopentyl glycol 2-3, Sodium Selenite 2-3, carboxymethyl cellulose 2-3, zinc sulfate 2-3, sal epsom 2-3, Oil of Eucalyptus 3-4, ammonium persulphate 3-5, water are appropriate; Preparation method adds each raw material except ammonium persulphate in suitable quantity of water, mixes, and grinds and makes slurry, and be heated to 80-90 ℃, then add ammonium persulphate, stirring reaction 40-60 minute, heating is concentrated into mud shape, and granulation, dries and get final product.

The concrete steps of the preparation of fertilizer are as follows:

(1) pulverize after diatomite is dried and mix with calcium superphosphate, fused(calcium magnesium)phosphate, urea, stir, obtain mixture, standby;

(2) Repone K, ammonium chloride, potassium permanganate are added to suitable quantity of water, be stirred to completely and melt, obtain mixed solution, earth is ground to form to slurry with mixed solution, standby;

(3) by grass meal with the mixture of step 1, the slurry of step 2, EM microbial inoculum and other remaining component are mixed, after adding suitable quantity of water to stir, carry out compost fermentation 20-25 days, during every turning 4-5 time;

(4) material step 3 having been fermented is sent in dryer and is dried, granulation.

Beneficial effect of the present invention:

Fertilizer of the present invention, adopts grass meal as main raw material, and the fertilizer making can make the nursery stock nutritive element balance absorption in each vegetative period, accomplished supplementing of each element of different growing stages, and reduced the loss of nutritive element, to root system without injury, fertilizer efficiency period is long, and utilization rate of fertilizer is high.The diatomite adding in addition has the advantages such as exquisiteness, loose, light weight, porous, water-absorbent and perviousness are strong, can play moisturizing, loose soil property, extends the drug effect fertilizer efficiency time in soil, encourages the effect of fruit tree growth.
