Abstract
The invention proposes a liquid mulching film with functions of cold protection, heat preservation and degradation. The liquid mulching film is a mulching film product which is combined by an organic hydrophilic binding agent, a film forming agent and inorganic element magnetized water, sprayed in fields and can play roles in cold protection, heat preservation and degradation. The liquid mulching film has the advantages of low manufacturing cost, obvious film formation on surface of soil as well as remarkable functions of cold protection and heat preservation.
Description
Technical field
The present invention relates to a kind of liquid-state mulch film with winter protection, insulation, degradation in the agriculture means of agricultural production technical field, be after utilizing organic hydrophilic adhesive, film forming agent, inorganic nutrients, carbon sugar, being interpreted into pasty state, to be sprayed at a kind of liquid-state mulch film product that can play winter protection, insulation, degradation on the field with magnetized drinking water.
Background technology
At present, there are many humus mulch film powders and liquid-state mulch film technical products in China, after some product applied the field soil surface, its film forming and cohesiveness were lower, the cracking that has, ventilative ventilation, the piece that hardens that the formation that has is hard, after a light rain dashed pouring, the decolouring demoulding added anion and non-ionic surface active agent in the product that has, not only do not have the effect of film forming, pollute to soil on the contrary.
The present invention designs a kind of novel liquid-state mulch film with winter protection, insulation, degradation on former mulch film and liquid film technical foundation.
Summary of the invention
The objective of the invention is to grow the family for peasant's kind provides a kind of liquid-state mulch film with winter protection, insulation, degradation, and its method is:
1, the lignin in the employing organic hydrophilic adhesive is as the main adhesive filming material of the liquid-state mulch film of winter protection, insulation, degradation.Lignin has emulsifying dispersivity, film forming, and stable in properties, figuration, water conservation, protecting colloid, solution viscosity are big, thickening, good fluidity, degradable, and mineral salt of anti-height the and outstanding characteristic such as turbid.
2, Propiram glue is the film forming agent and the adhesive of extensive use in the food industry, also is the primary raw material of medical capsule shells.This glue can expand in water in free complete miscibility, and dissolution velocity is faster more than two times than CMC, algin.Solution neutral, not ionization, not gelation, non-crystallizable, good film-forming property, tough film has characteristics such as oil resistivity, gas barrier properties, maintenance aromaticity, electrical insulating property and salt tolerant, alkaline-resisting and warm tolerance, is desirable film forming flexibilizer and crosslinking agent of liquid-state mulch film.
3, calcium sulphate, borax, urea, carbon fried sugar element.Interpolation calcium sulphate, borax are in order to increase the toughness of active substance in organic colloidal solution, to improve the tensile strength and the extensibility of film.The order ground that adds urea and carbon fried sugar element is to be the raising of GL-PP in the organic solution to nitrogen, carbon ratio film forming increasing tougheness, also is to the improvement of soil and replenishing soil nutrient in the back of progressively degrading.
4, a kind of liquid-state mulch film with winter protection, insulation, degradation through more than 2 years in the field of farm, the northern many provinces and regions of China, peasant household to Different Crop after planting the spray test effect show, though insulation, but winter protection effect quite plastic film is also slightly poorer, but to improve the 2-3 degree with 18-26cm place ground temperature under the soil face of land of not covering plastic film, and seedling can be broken ground automatically and grown, after 30 days progressively slowly-releasing become fertilizer, equal to have appended disposable fertilizer again for crops.After the present invention had the liquid-state mulch film sprinkling upper soll layer of winter protection, insulation, degradation, forming thickness immediately was the very thin skim of 0.3-1.2mm, natural seasoning after 4-9 hour, 24 as a child after, film bottom humidity strengthens gradually, and insulation, the water conservation effect is particularly outstanding, quite the field corn mu of overlay film volume increase 110kg not, wheat increase yield 58kg, potato production promoting 93kg, soybean yield-increasing 46kg does not pollute environment, soil, but also can improve the soil, increase the fertility of soil.
Embodiment
A kind of liquid-state mulch film with winter protection, insulation, degradation, its technology is:
1,18 kilograms of running water is heated to 45 when spending, after handling by the magnetization of 3000 Gauss's magnetic taps, puts into Plastic Drum, add Propiram glue 50 grams, the limit edged stirred after 1 minute, and is quiet to 30 minutes, and then add lignin 700 grams, calcium sulphate 140 grams, urea 100 grams, borax 50 grams, plain 100 grams of carbon fried sugar, the limit edged stirs, and treats that it is all after the dissolving, in another Plastic Drum of dress people, seal, put in storage.
Claims (3)
1.18 kilogram running water heating 45 degree;
2. handle by the magnetization of 3000 Gauss's magnetic taps;
3. Propiram glue 50 restrains, lignin 700 grams, calcium sulphate 140 grams, urea 100 grams, borax 50 grams, carbon fried sugar element 100 grams.
