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 invention provides a kind of Fully-degradable liquid medical membrane for paddy field, belong to agricultural production application field.
Background technology
Plastic film cultivation technique is utilized to be one of well-known ten multi-form agriculture technology in this century.Use mulch film can meet farm crop insulation, soil moisture conservation, improve the object 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 physical environment, spoiled soil and physical environment, cause environmental pollution.Therefore degradable mulch causes the broad interest of people.Degradable mulch is divided into solid mulch film and liquid ground film by its form, solid mulch film is due to intensity needs that are shaping, that transport and use, and thickness opposed plastic mulch film is thicker, and price is generally also higher than plastic film, the overwhelming majority is also difficult to thorough degraded, and application is subject to certain restrictions.
Initial degradable mulch is incorporated in common polyethylene film by starch and organic acid thereof, because polyethylene can not be decomposed by the microorganisms, can't eliminate white pollution.Be eliminated.Degradable mulch in recent years based on polyvinyl alcohol becomes the focus of degradable mulch research, and because polyvinyl alcohol price is higher, consumption, all more than 30%, uses this type of degradable mulch cost higher.When existing solid mulch film uses in addition, bothersome effort, and mulch film difficulty is used for irregular plot.
Liquid ground film due to degradation property good, cost is low, the advantage such as on-the-spot spraying film forming can have been paid close attention to by people and used.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 the multifunction degradable black liquid state mulch film that CN1459471A mentions and CN101481508 humic acid multifunctional degradable black mulch film all belong to the liquid-state mulch film that scene sprays, these mulch films all design for dry land, and also do not have a degradable liquid film being exclusively used in Rice Cropping at present.And paddy field is also relevant large in the acreage under cultivation of China, be also one of our staple food crop, according to the growth characteristic of paddy rice, provide a kind of Fully-degradable liquid medical membrane for paddy field to be very necessary.
Summary of the invention
The present invention is intended to the deficiency for existing in background technology, provides a kind of Fully-degradable liquid medical membrane for paddy field.
Fully-degradable liquid medical membrane for paddy field of the present invention is prepared from by weight by following material: potassium silicate 5 ~ 12 parts, polyacrylic resin 1 ~ 6 part, treated starch 15 ~ 40 parts, Machete 10 ~ 28 parts, 4 ~ 12 parts, urea, 15 ~ 40 parts, water, 500 ~ 800 object carbon black 1 ~ 10 part.
Preferred component of the present invention is: potassium silicate 6 ~ 10 parts, polyacrylic resin 1 ~ 6 part, treated starch 18 ~ 35 parts, Machete 12 ~ 25 parts, 6 ~ 12 parts, urea, 18 ~ 33 parts, water, carbon black 1 ~ 8 part.
Fully-degradable liquid medical membrane for paddy field of the present invention makes as follows:
A, potassium silicate, Machete, urea, carbon black, polyacrylic resin to be mixed mutually, stir at 20 ~ 70 DEG C;
B, in the mixed solution that a step is obtained, add treated starch, water, carry out being stirred well to dissolving completely, at 20 ~ 70 DEG C, be incubated 10 ~ 120 minutes, the finished product namely made.
Potassium silicate of the present invention:
Fully-degradable liquid medical membrane for paddy field of the present invention, has the following advantages:
1, this liquid membrane is black, improves the heat absorption capacity of mulch film, can suppress again the growth of weeds simultaneously;
2, treated starch can be degenerated and is decomposed into humic acid, and potassium silicate is decomposed into the absorbable siliceous fertilizer of crop and potash fertilizer, thoroughly solves mulch film to soil and environmental pollution, adds fertilizer and agricultural chemicals simultaneously, play strong stalk, resistant to lodging, disease-resistant, volume increase effect;
3, manufacture craft is simple, good stability;
4, convenient transportation, mu consumption is few, and cost is low;
When 5, emerging, naturally can emerge without artificial seedling setting, save a large amount of man power and materials;
6, be sprayable saving of work and time after being watered, easy and simple to handle, be easy to promote.
