Abstract
The invention provides a fully-degradable liquid medical membrane for paddy field and belongs to the application field of agricultural production. The fully-degradable liquid medical membrane is composed of potassium metasilicate, polyacrylic resin, modified starch, Machete, urea, water and carbon black. The liquid medical membrane provided by the invention can be used to raise heat absorption performance of mulching film and inhibit the growth of weed. The modified starch can be decomposed into humic acid. Potassium metasilicate is decomposed into silicon fertilizer and potash fertilizer which can be absorbed by crops. Therefore, the pollution of the mulching film to soil and environment is thoroughly solved. In the meanwhile, by the addition of a fertilizer and a pesticide, the fully-degradable liquid medical membrane has effects of strengthening stalk, resisting lodging, resisting diseases and increasing yield. The invention has advantages of simple manufacturing technology, good stability, strong pertinency, convenient transportation and low cost, is used to save a lot of manpower and material resources, is convenient to operate, and is easy to popularize.
Description
Technical field
The present invention provides a kind of rice terrace all-degradable liquid medicine film, belongs to the agricultural production application field.
Background technology
Utilizing the plastic film cultivation technique is one of well-known ten multi-form agriculture technology in this century.Using mulch film can satisfy farm crop insulation, soil moisture conservation, improve the purpose that fertilizer efficiency reaches increasing both production and income.But because plastic film is difficult to decompose in physical environment, be scattered in soil and the physical environment, destroy soil and physical environment, cause environmental pollution.Therefore degradable mulch has caused people's extensive interest.Degradable mulch is divided into solid mulch film and liquid ground film by its form; The solid mulch film is because the intensity of moulding, transportation and use needs, and the relative plastic film of thickness is thicker, and price generally also is higher than plastic film; The overwhelming majority also is difficult to thorough degraded, uses to receive certain restriction.
Initial degradable mulch is that starch and organic acid thereof are incorporated in the common polyethylene film, because Vilaterm can not can't be eliminated white pollution by microbiological degradation.Be eliminated.Be the focus that main degradable mulch becomes degradable mulch research in recent years with the Z 150PH, because the Z 150PH price is higher, consumption uses this type of degradable mulch cost higher all more than 30%.When existing in addition solid mulch film uses, the bothersome effort, and use the mulch film difficulty for irregular plot.
Liquid ground film is because degradation property is good, and cost is low, and advantages such as the film forming of can on-the-spotly spraying are paid close attention to by people and used.Multifunction degradable black liquid state mulch film and CN101481508 humic acid multifunctional degradable black mulch film that a kind of multifunctional degradable liquid-state mulch film that the spray of invisible mulch-film that the multifunctional degradable black farm mulching that Chinese patent CN1277228 mentions, CN120944 mention, CN1935878 mention and CN1459471A mention all belong to the liquid-state mulch film that the scene sprays; These mulch films all design to dry land, and also do not have a degradable liquid film that is exclusively used in the paddy rice plantation at present.And the paddy field also is relevant big in the acreage under cultivation of China, also is one of our staple food crop, and according to the growth characteristic of paddy rice, it is very necessary that a kind of rice terrace all-degradable liquid medicine film is provided.
Summary of the invention
The present invention is intended to the deficiency that exists in the background technology a kind of rice terrace all-degradable liquid medicine film is provided.
Rice terrace all-degradable liquid medicine film of the present invention is to be prepared from by weight following material: 5～12 parts of potassium silicates, 1～6 part of WL 140,15～40 parts of treated starches, 10～28 parts of Machetes, 4～12 parts in urea, 15～40 parts in water, 1～10 part of 500～800 purpose carbon black.
Preferred component of the present invention is: 6～10 parts of potassium silicates, 1～6 part of WL 140,18～35 parts of treated starches, 12～25 parts of Machetes, 6～12 parts in urea, 18～33 parts in water, 1～8 part of carbon black.
Rice terrace all-degradable liquid medicine film of the present invention is to process through following steps:
A, potassium silicate, Machete, urea, carbon black, WL 140 are mixed mutually, under 20～70 ℃, stir;
B, in the mixed solution that a step makes, add treated starch, water, be stirred well to dissolving fully, at 20～70 ℃ of insulations 10～120 minutes down, i.e. finished products of system.
Potassium silicate of the present invention:
Rice terrace all-degradable liquid medicine film of the present invention has the following advantages:
1, this liquid membrane is black, has improved the heat absorption capacity of mulch film, can suppress the growth of weeds simultaneously again;
2, treated starch can be degenerated and is decomposed into humic acid, and potassium silicate is decomposed into absorbable siliceous fertilizer of crop and potash fertilizer, has thoroughly solved mulch film to soil and environmental pollution, and having has simultaneously increased fertilizer and agricultural chemicals, play strong stalk, resistant to lodging, disease-resistant, the raising the output effect;
3, manufacture craft is simple, good stability;
4, convenient transportation, the mu consumption is few, and cost is low;
When 5, emerging, can emerge naturally, save great amount of manpower and material resources without artificial seedling setting;
6, be sprayable saving of work and time after converting water, easy and simple to handle, be easy to promote.
