Abstract
The invention discloses a preparing method and application of a peat humic acid degradable liquid mulching film containing rare-earth micro-element fertilizers and anti-freezing agents. The preparing method includes the technological steps that after fine selection and sundry removal are carried out on peat humic acid, the peat humic acid is smashed into powder ranging from 80 meshes to 400 meshes, raw materials are evenly stirred according to the weight ratio that the peat humic acid: mulching film-forming agents: cross-linking agents: the anti-freezing agents: rare earth: annexing agents: water = 3-10:1-5:0.2-1:0.5-1:0.1-1:0.2-0.5:30-60, the raw materials are reacted for 0.5 hours-2 hours at 20 DEG C-90 DEG C, and the peat humic acid degradable liquid mulching film containing the rare-earth micro-element fertilizers and the anti-freezing agents is generated. The peat humic acid degradable liquid mulching film has the good warming performance and the good low-temperature-resistant performance; when hot water cannot be provided due to condition limitation, cold water can be directly used to be evenly stirred with the raw materials to be sprayed to form the mulching film, and complete degradation can be achieved after the peat humic acid degradable liquid mulching film is used for 2-3 months.
Description
Technical field
The invention provides a kind of humic acid in peat degradable liquid-state mulch film containing RE microbial fertilizer and antifreezing agent, belong to agricultural production application field.
Background technology
For realizing the object of agricultural production and income, utilize plastic film to carry out culture technique and adopted by vast farmers.But residual " white pollution " problem of agricultural plastic ground membrane is difficult to solve; safety, the sustainable development of agricultural in serious threat; reduce farmland mulch film residual, the ecotope that protects the fields, the feasible method of eliminating plastic film white pollution is exploitation and uses degradable mulch.As the liquid-state mulch film that has market application foreground, cause that people study interest greatly.
Humic acid is a kind of organic macromolecule compound that occurring in nature extensively exists, and is the main component of humus in rich soil, in coal, marsh, pond, irrigation canals and ditches mud, exists in a large number.Because humic acid has good chemistry and biologically active, research and the application of the liquid mulch film of humic acid also arouse great concern.But no matter be to have or be made into liquid state the powdery of being convenient to transportation, all also exist some problems to need to improve, during as reaction, all need to be heated to higher temperature or use hot water, bring certain difficulty to practical operation; In the time that used spring, Low Night Temperature easily causes film rupture; Heating performance needs further to be improved etc.
Summary of the invention
For the problems referred to above, the present invention proposes a kind of new technical scheme, can significantly improve the performance of the liquid mulch film of humic acid, make them more can realistic application needs.
The object of the present invention is to provide a kind of humic acid in peat degradable liquid-state mulch film containing RE microbial fertilizer and antifreezing agent.
Object of the present invention is achieved through the following technical solutions:
(1) commercially available content is crushed to 80～400 orders after the selected impurity elimination of more than 30% humic acid in peat, obtains humic acid in peat powder;
(2) by humic acid in peat powder: film forming agent: crosslinking agent: antifreezing agent: rare earth: additive: the weight proportion of water=3～10:1～5:0.2～1:0.5～1:0.1～1:0.2～0.5:30～60 mixes and stirs, 20～90 ℃ of reactions generate the humic acid in peat degradable liquid-state mulch film containing RE microbial fertilizer and antifreezing agent for 0.5～2 hour;
(3) while sprinkling, add the water dilution of 2～5 times of humic acid in peat degradable liquid-state mulch film weight that step (2) makes, stir, guarantee not have to be sprayed on ground after particle and get final product film forming, every mu of humic acid in peat degradable liquid-state mulch film 10～15 Kg that use step 2 to make.
The film forming agent using is one or more in sodium alginate, polyvinyl alcohol, pentalyn, polyvinyl acetate;
The crosslinking agent using is triethylene tetramine, diethylenetriamine, TEPA, N, one or more in N`-methylene-bisacrylamide;
The antifreezing agent using is one or more in ethylene glycol, glycerine;
The rare earth using is rare earth nitrades or chloride;
The additive using is one or more in nano-calcium carbonate, nano calcium oxide, nano silicon;
After using the warm water of cold water or 40～60 ℃ to stir by above-mentioned formula, all can react film forming.
The present invention has the following advantages:
(1) in formula, added RE microbial fertilizer, utilized the photo absorption performance of rare earth material, promoted the performance that heats of material, can make soil on average heat 3～4 ℃, RE microbial fertilizer can also further promote crop growth in addition.
(2) in formula, add antifreezing agent, effectively improved the resistance to low temperature of product, within freezing 10 hours, had no any cracking phenomena that becomes fragile at-15 ℃.
(3), while use, while being subject to condition restriction that hot water cannot be provided, spray film forming after can directly using cold water to stir in the wild.
(4) do not introduce environmentally harmful chemicals, can realize environmental-protection fully-degradable, generally after 2-3 month, can realize degradable in use.
