Abstract
A kind of agricultural mulching powder material belongs to agricultural mulching manufacturing technology field.It is characterized in that it is a kind of agricultural mulching powder material that the self-decomposition slowly-releasing is put the chemical fertilizer mulch film that is used to make.It is that polyvinyl alcohol (powder), nutrient substance (powder) and benzophenone series or benzotriazole are the mixture of uv-absorbing agent, wherein, the polyvinyl alcohol powder accounts for more than 60% of weight ratio, and uv-absorbing agent accounts for 0.1～0.5% of weight ratio, between rise and stop self-decomposition and enhancement.It has can decompose voluntarily, not produce refuse, but slowly-releasing is put chemical fertilizer and film forming is simple and easy, advantage easy to use again.
Description
A kind of agricultural mulching powder material belongs to agricultural mulching manufacturing technology field.
Agricultural mulching commonly used can keep ground temperature, but its shortcoming is: can't self-decomposition, can produce waste material, and it is also unfavorable to soil promptly to enable its residue of self-decomposition; Need the processing film forming in addition, the cost of manufacture height uses inconvenience, and waste is also big.
The object of the present invention is to provide and a kind ofly can be used for making the self-decomposition slowly-releasing and put the agricultural mulching powder material that the chemical fertilizer mulch film is used.
The invention is characterized in: it be a kind of be the mixture that uv-absorbing agent is formed by polyvinyl alcohol powder, nutrient substance powder and as benzophenone series or benzotriazole that toughener is used, wherein, the polyvinyl alcohol powder accounts for more than 60% of weight ratio, uv-absorbing agent accounts for 0.1%～0.5% of weight ratio, rises to stop self-decomposition and enhancement.
Use proof: add the mulch film that sprays formation behind a certain proportion of water with mixture proposed by the invention and have advantages such as self-decomposition, slowly-releasing puts nutrient substance and film forming is simple and easy, and is easy to use.
Embodiment:
| Component and effect weight ratio | Polyvinyl alcohol | Urea | Starch | UV-9 | UV-P | The self-decomposition time (my god) |
| 1 | 70 | 20 | 9.9 | 0.1 | 15 | |
| 2 | 70 | 29.8 | 0 | 0.2 | 30 | |
| 3 | 70 | 29.7 | 0.3 | 60 | ||
| 4 | 70 | 20 | 9.9 | 0.1 | 20 | |
| 5 | 70 | 29.8 | 0 | 0.2 | 40 | |
| 6 | 70 | 0 | 29.7 | 0.3 | 80 |
Wherein, UV-9 is 2-hydroxyl-4-methoxy benzophenone.UV-P be 2-(2 '-hydroxyl-5 '-methoxyphenyl)-trade name of 5-chlorobenzotriazole.
As long as adding certain temperature, a certain proportion of water during use makes the aqueous solution of mulch film and sprays with atomizer.
Use proof: but both self-decompositions do not produce the disadvantageous waste material of soil, but slowly-releasing is put chemical fertilizer again, and film forming is simple and easy, easy to use.
