Description
Technical field
The present invention relates to kind clothing agent, specifically relating to a kind of is the drought-resistant water-preserving kind clothing agent of main component with the vegetable fiber, and uses thereof.
Technical background
Seed coating technology is a kind of practical technique that is widely used in agricultural, forestry and gardening that grows up over nearly 30 years.1978, U.S. scientist handled cotton seeds, the damping off of having prevented and treated cotton effectively with the kind clothing agent that sorbose and sticker etc. is mixed with.1981, Soviet Union scientist has researched and developed can be in film forming kind of clothing agent of the surface of the seed, the effect of when handling cotton seed, sunflower, corn, beet and legume-seeds, not only having played kill pathogens and having improved the field percentage of seedgermination, and can suitably do sth. in advance sowing time, thereby prolonged crop alimentary vegetative period, improved crop yield.Nineteen eighty-two, the United States Department of Agriculture research center is developed into the agent of soybean kind clothing with high molecular polymerization agricultural chemicals compound prescription, has improved the soybean germination situation greatly, greatly improves and developed seed coating technology.This shows the importance of seed coating technology, and Japanese scientist calls this technology " cornerstone that is agricultural foison " especially.
The kind clothing agent that is used for " water conservation " effect commonly used at present mainly is made up of acrylic polymer.As the agent of acrylamide and acrylic acid crosslinking copolymerization species clothing, its water absorption rate height, the life-span is long, and be suitable for mixing soil and use, but too thickness, gas permeability difference and cost height.Though and the crosslinked species clothing of starch-grafted acrylic acid copolymer agent cost is low, the life-span is short, and the water conservation effect is also undesirable.This class kind clothing agent is difficult to satisfy simultaneously seed germination required " three big key elements "---moisture, temperature and oxygen, is difficult to solve the contradiction of " breathing freely " and " water conservation ".Disclosed kind of clothing agent is key component with insecticide, bactericide among the Chinese patent CN1259284A for another example, and it has solved the defective of planting clothing agent function singleness, but its water conservation effect is bad.
Summary of the invention
The objective of the invention is to overcome contradiction or function singleness and the unfavorable defective of " water conservation " effect that existing kind of clothing agent is difficult to solve simultaneously " breathing freely " and " water conservation ", thus provide a kind of based on vegetable fiber, water conservation is effective and antibiotic, can improve seed sprouting speed, drought-resistant water-preserving kind clothing agent with low cost.
Another object of the present invention provides the purposes of described drought-resistant water-preserving kind clothing agent.
The objective of the invention is to realize by following technical scheme:
The invention provides the agent of a kind of drought-resistant water-preserving kind clothing, comprise following component:

Bentonite 20～40 weight portions;
Bactericide is or/and insecticide 3～6 weight portions;
Straw powder wherein be with the straw of 30～60 weight portions, 1～3 weight portion chemical fertilizer, 1～3 weight portion plant growth substance, and the water of 120～140 weight portions add successively in the reactor, fully stirred 4 hours at 60～70 ℃; The mixture crushed after being dried that obtains becomes 100～200 purpose fine powders, obtains the powder of straw of phosphatideization; Described chemical fertilizer can be potassium dihydrogen phosphate, urea or ammonium nitrate; Described plant growth substance can be heteroauxin, r-methyl, gibberellin or triacontanol;
Water-loss reducer is high hydroscopic resin (being designated hereinafter simply as SAP), comprises the copolymer of polyacrylic acid, polyacrylate, acrylic acid-acrylamide or the copolymer of acrylic acid-cis-butenedioic anhydride;
Film forming agent is the water mixing with the maleic anhydride of 10～20 parts by weight of acrylic, 2～4 weight portions and 30～40 weight portions, uses NaOH to be neutralized to reactant liquor and is neutral; Add initator and aided initiating successively, 60～70 ℃ of polyase 13～4 hour; Described initator is ammonium persulfate or dibenzoyl peroxide, and aided initiating is sodium hydrogensulfite, bisulfite amine or ferrous-hydrogen peroxide;
Described bactericide can be carbendazim, Triadimenol or tmtd; Described insecticide can be carbofuran, Imidacloprid or tefluthrin;
The straw powder of aforementioned proportion, water-loss reducer, film forming agent, bentonite, bactericide or/and insecticide mixes, are obtained drought-resistant water-preserving kind clothing of the present invention agent.
The invention provides the purposes of a kind of above-mentioned drought-resistant water-preserving kind clothing agent, can be with clover, corn, wheat, after paddy rice and trees, various seeds such as vegetables and drought-resistant water-preserving kind clothing provided by the invention agent add water and mix, after at room temperature stirring, drying, wherein the weight ratio of agent of drought-resistant water-preserving kind clothing and seed is 1: 15～40.
The advantage of drought-resistant water-preserving kind clothing provided by the invention agent is:
1, the solvent of this kind clothing agent is a vegetable fiber, 600～800 times of water absorbent rates, and good permeability can not harden, and is easy to degraded, to environment friendly and pollution-free;
2, the agent of this kind clothing is met water and can be expanded in soil, can once not dissolved, and seed can slowly absorb nutrition, prolongs fertilizer efficiency period;
3, has multiple fertilizer efficiency, contain various elements and plant growth regulator such as nitrogen, phosphorus, potassium, therefore played the effect of nutrition, desinsection, sterilization and growth regulating simultaneously, can reach the anti-adversity ability of drought-relief, the speed of germination that improves seed and germination rate, enhancing crop, help the growth of crop;
4, the agent of this kind clothing can be blocked bacterium and the viral approach to the seed infringement in the soil, improves the resistance against diseases of seed;
5, the agent of this kind clothing can be controlled the rate of release of agricultural chemicals, little fertile isoreactivity component, makes behind the planting seed effectively prevention and elimination of disease and pests and guarantee that plant growth germinates in this long period of seed sprouting, growth of seedling and even mid-term;
6, improve seeding quality, promote plant growth, root system is powerful, and strong stress resistance is protected and produced volume increase;
7, the preparation method who produces the agent of this kind clothing temperature influence not can at room temperature cause, polymerization, and is simple to operate, is easy to produce; And preparation process do not produce waste water, waste residue, do not produce problem of environmental pollution; Technological process is short, and cost is low, energy consumption is little, is not subjected to the restriction in place.
Use drought-resistant water-preserving kind clothing provided by the invention agent that wheat and corn are carried out Cotton seeds, the wheat seed cost per mu increases by 8 yuan, and germination rate improves 20%, and output increases about 20%; The corn seed cost per mu increases by 5 yuan, and germination rate improves 25%, and output improves 20%; Used water conservation kind clothing of the present invention agent that ornamental trees and shrubs North America sweetgum and cdear seed are carried out Cotton seeds, its germination rate has improved 20%-25%, and survival rate has improved 20%-25; Clover is carried out Cotton seeds, and cost increases by 12 yuan, and germination rate improves 15%, and output increases by 20%.
