Example Embodiment

[0058] Example 1 Solid film

[0059] Take 100kg of bamboo vinegar liquid, fractionated in the fractionation column, refined the product, to give 45 kg refined bamboo vinegar, pH 4.8, GC-MS (dissolved in dichloromethane) to test the phenolic compound in organic matter The weight percentage is 54.6%.

[0060] Add 0.9 kg of sodium selenate, 0.225 kg of phosphate, 1.125 kg of zinc sulfate and 1.125 kg of manganese sulfate, mixed, glycyne, and mixed, glycyne, which is uniformly mixed.

[0061] Rice shell activated carbon and bamboo activated carbon weight ratio 8: 2, particles 2-4mm, average pH 8.9, average specific surface area 1180m 2 / g, the total weight of 45kg, mixed in the cylindrical filter, the additive-containing bamboo vinegar fluid naturally flows through the filter, so that the effective component is sufficiently activated by activated carbon after 3.5 hours, and the activated carbon composite material is obtained. .

[0062] 3.75 kg of xanthan gum, 0.75 kg of glycerol, an...

[0069] Example 2 Liquid film

[0070] Active carbon composite material and fragrant fake epidermal extract with Example 1.

[0071] 3.75 kg of xanthan gum, 0.75 kg of glycerol, derive starch (phosphate starch of the degenerative starch (substitution 0.08), 30 kg of sodium carboxymethylcellulose, 1.5 kg, 45 kg of dodecylbenzenesulfonic acid, 0.75 kg, and 60 ° C Hot pure water 95kg, mix well, to obtain a biosensitive water suspension.

[0072] The activated carbon composite material was subjected to a fineness of 600 mesh, which was 1.5kg, 5kg hemoder (fiber length 2 mm), and mixed well and mixed with a full-degraded film film. The floor film is a liquid film. When using a full-degraded floral film and water, it is mixed with water than 1: 1, and the mountain is in front of the mountain, and it can't rain 24 hours after spraying. If you need to be re-rain Spraying; after spraying 24 hours, the ground film is substantially cured, and a black full degraded floral film is formed on the...

Abstract

The invention discloses a full-degradable mulching film for mountain rice planting and a preparation method thereof. The mulching film is composed of the following components in parts by weight: 45 to 120 parts of bamboo vinegar, 10 to 50 parts of activated carbon, 1 to 5 parts of torreya grandis aril extract, 10 to 50 parts of a biological adhesive and 5 to 45 parts of fibers. The mulching film has the effects of preventing weeds, killing bacteria, expelling parasites, improving lodging resistance of mountain rice and the like, can be completely degraded, and is particularly environment-friendly. The preparation method of the mulching film is simple to operate and easy for industrial production and popularization.

Description

technical field [0001] The invention relates to the field of plastic film technology, in particular to a fully degradable plastic film for upland rice planting and a preparation method thereof. Background technique [0002] Mountain rice, also known as upland rice, is a non-hybrid upland rice variety suitable for cultivation in mountainous areas. Compared with ordinary rice, due to its growth environment, mountain rice has the advantages of rich mineral elements, high B vitamin content, and no pesticide residues. However, due to the special growth environment of mountain rice, there are also some defects. , the high content of cadmium in the soil may lead to the enrichment of cadmium in mountain rice. [0003] In addition, according to the inventor's observations, common underground pests in mountainous areas, such as japonica ants, wireworms, grubs, weevils, etc., will harm the seeds and buds of mountain rice. Due to the limitation of the mountainous environment, mountain...
