Abstract
The invention discloses a water-retention slow-release fertilizer for taxus chinensis and a preparation method thereof; the water-retention slow-release fertilizer is prepared from the following raw materials in parts by weight: 10-12 parts of attapulgite, 7-9 parts of zinc sulfate, 8-10 parts of tricalcium phosphate, 5-6 parts of ammonium molybdate, 6-8 parts of potassium dihydrogen phosphate, 5-7 parts of urea, 6-8 parts of ammonium chloride, 3-4 parts of epoxy chloropropane, 5-7 parts of carboxymethyl starch, 3-5 parts of diammonium phosphate, 4-6 parts of carnallite, 20-30 parts of cellulose graft acrylate, and 15-25 parts of starch graft acrylamide. The prepared water-retention slow-release fertilizer has the advantages of low cost and convenient application; the added various inorganic matters meet nitrogen, phosphorus, potassium and other mineral substances and trace elements required for taxus chinensis growth, and ensure normal growth of taxus chinensis; the added cellulose graft acrylate and starch graft acrylamide can effectively keeps moisture in soil, and prevent the moisture from evaporating faster so as to prevent from affecting plant growth. The water-retention slow-release fertilizer has both good water retention and good slow-release performance, has the utilization rate of fertilizer elements improved, reduces the environmental pollution, and promotes crop growth.
Description
Invention field
The present invention relates to a kind of fertilizer, specifically relate to a kind of Ramulus et folium taxi cuspidatae Water-retaining slow-release fertilizer and preparation method thereof.
Background technology
Ramulus et folium taxi cuspidatae, has another name called Japanese yew, is a kind of plant of Taxus.Taxus is in shallow rooted plant, and its main root is not obvious, side root flourishing, is generally acknowledge endangered natural rare plants for anticancer in the world, has been through the ancient few survivors seeds that quaternary glacier carries over, on earth the history of existing 2,500,000 years.Because growth of taxol speed is slow under field conditions (factors), regenerative power is poor, so for a long time, has not also formed the Ramulus et folium taxi cuspidatae raw material forestbase of advising greatly and touching in world wide.Within 1994, Ramulus et folium taxi cuspidatae is decided to be one-level rare endangered plants by China, and had the country of Ramulus et folium taxi cuspidatae to be called " national treasure " by 42, the whole world, United Nations also prohibites felling, is " plant giant panda " worthy of the name simultaneously.
Ramulus et folium taxi cuspidatae, at the equal suitable planting in various places, Chinese north and south, has the advantages that happiness is shady, drought-enduring, cold-resistant, requires that P in soil H value is at 5.5-7.0.The resistance to the moon of habitat property, also can grow under thick forest, perennial, does not grow into forest.Be more common in the theropencedrymion based on Korean pine.Be born on the many stone in mountain top or barren soil, many in shrub shape.The average annual temperature in country of origin 2 DEG C to 7 degree, average annual precipitation 750 ~ 1000 millimeters.How scattered under moistening, the fertile theropencedrymion of Schattenseite or half Schattenseite.Property happiness nice and cool moist climate, can the low temperature of resistance to subzero less than 30 DEG C, winter resistance is strong, optimum temperuture 20 ~ 25 DEG C, genus feminine tree.Like moistening but be afraid of flood, being suitable for planting on loose moistening well-drained sand loam.
Growth of taxol needs nitrogen, phosphorus, potash fertilizer, and nitrogenous fertilizer can promote flowers and plants shoot and leaf growth, and phosphate fertilizer can promote its flower, fruit is formed, and potash fertilizer can promote the growth of stem and root.Ramulus et folium taxi cuspidatae avoids Shi Shengfei, dense fertilizer, and fertilising should based on nitrogen phosphorus fertilizer, can not overrich.This just needs one can slow releasing fertilizer efficiency, and has the fertilizer of water conservation effect.
Summary of the invention
The object of this invention is to provide a kind of Ramulus et folium taxi cuspidatae Water-retaining slow-release fertilizer and preparation method thereof.
For achieving the above object, the technical solution used in the present invention is:
A kind of Ramulus et folium taxi cuspidatae Water-retaining slow-release fertilizer, it is characterized in that, with parts by weight, formed by the preparation of raw material of following weight part: attapulgite 10-12 part, zinc sulfate 7-9 part, tricalcium phosphate 8-10 part, ammonium molybdate 5-6 part, potassium primary phosphate 6-8 part, urea 5-7 part, ammonium chloride 6-8 part, epoxy chloropropane 3-4 part, carboxymethyl starch 5-7 part, diammonium phosphate 3-5 part, carnallitite 4-6 part, cellulose graft acrylate 20-30 part, starch graft acrylamide 15-25 part.
A preparation method for Ramulus et folium taxi cuspidatae Water-retaining slow-release fertilizer, is characterized in that, comprises the following steps:
(1) attapulgite, carnallitite, hectorite are ground into 60-80 order powder, then put into stirring tank and be dry mixed 8-10min together with tricalcium phosphate, potassium primary phosphate, carboxymethyl starch under the rotating speed of 300-400r/min, obtain Preblend;
(2) zinc sulfate, ammonium molybdate, urea, ammonium chloride, diammonium phosphate are added successively in 15-20 water doubly, limit edged is stirred to and dissolves completely, obtains mixing solutions;
(3) mixing solutions that step (2) obtains is joined in the Preblend that step (1) obtains; add epoxy chloropropane, cellulose graft acrylate, starch graft acrylamide mixing and stirring again; then add in appropriate water feeding tablets press and carry out granulation, obtain described Ramulus et folium taxi cuspidatae Water-retaining slow-release fertilizer.
Beneficial effect of the present invention:
The Water-retaining slow-release fertilizer that the present invention obtains, with low cost, use easy, the various inorganicss added meet mineral substance and the trace elements such as the N P and K needed for growth of taxol, ensure that its normal growth, the cellulose graft acrylate added, starch graft acrylamide effectively can keep the moisture in soil, and preventing moisture from evaporating comparatively fast affects plant-growth.Water-retaining slow-release fertilizer of the present invention not only has good water-retentivity but also have good slow-releasing, and fertilizer element utilization ratio improves, and alleviates environmental pollution, promotes plant growth.
