Problems solved by technology

[0003] For example, after the mulch film is placed, it needs to be recycled, but the recycling is done manually, which makes it difficult to recycle and causes high recycling costs; at the same time, the mulch film that has not been recycled is not easy to degrade. According to current research, it takes about 300 years for the polyethylene mulch film to completely decompose. time, which caused serious white pollution
[0004] In addition, in addition to high labor costs and environmental pollution, there are also many defects in use.
[0005] For example, because the plastic is not breathable, it is easy to cause water vapor to accumulate to form mist, which reduces the light transmittance of the mulch, which in turn affects the growth of plants under the mulch; and because the traditional polyethylene (polyvinyl chloride) mulch does not have gaps, Th

Example Embodiment

[0042] Example 1:

[0043] Polypropylene 10g / m 2 , 2 layers of tung oil coating.

[0044] For planting flue-cured tobacco

[0045] Steps: (1) seedling cultivation; (2) transplanting; transplanting to the soil, using single ridge planting; (3) fertilizing and watering; (4) pest control; (5) topping and wiping branches; (6) mature picking ;

[0046] Transplanting under the film is adopted, in which the white shell degradable mulch film covers the tobacco plant growth area, and the black new degradable mulch film covers both sides of the growth area to prevent the growth of weeds.

[0047] The steps of raising seedlings, transplanting, fertilizing and watering, pest control, topping and wiping, and mature picking are carried out in accordance with general agricultural affairs.

[0048] The following table shows the effect of heat preservation and water retention:

[0049]

[0050] After this product is covered, the tobacco plant has been broken down into pieces during the prosperous period,...

Example Embodiment

[0057] Example 2

[0058] Used for peanut mulching cultivation, polypropylene 10g / m 2 , 2 layers of tung oil coating, calcium carbonate 2g / m 2 .

[0059] It is very important to master the sowing period. Peanuts can be sown from May 15th to 25th, and peanuts with plastic film can be sown from May 10th to 15th. Within 5 days, the average daily ground temperature of 5-10 cm of cultivated layer can be planted after passing 12℃. The peanuts covered with plastic film can increase the ground temperature; the planting is even and the plastic film is close to the ridge surface. Throw two shovel soil every 2-3 meters to prevent the wind from lifting the film. Film-mulched peanuts cannot be cultivated and must be sprayed and weeded before mulching.

[0060] Others are the same as ordinary planting methods.

[0061] Peanuts covered with plastic film can recover the effective accumulated temperature of 230~270℃. According to the above method, peanuts can produce more than 1000~2000 kg per hecta...

Abstract

The invention proposes a degradable mulch film coated with tung oil, which comprises a non-woven fabric and a tung oil layer, and the tung oil layer is coated on the non-woven fabric layer. The degradable plastic film coated with tung oil is degradable. When the plant grows and needs to be removed, it has been degraded by itself, eliminating the cost of manual recycling, and can be used for the cultivation of crops such as corn, strawberry, cotton, peanut and tobacco. At the same time, in view of the large pore size of the single-layer non-woven fabric structure, which causes serious air permeability and reduced heat preservation and water retention effects, a layer of tung oil is coated on the surface of the non-woven fabric to encrypt the overall structure, thereby improving heat preservation and water retention. performance.

Description

technical field [0001] The invention relates to the field of agricultural production, in particular to a degradable plastic film coated with tung oil. Background technique [0002] In the process of planting many crops, especially tobacco plants, in order to obtain a better growth environment, mulch is used, while the traditional mulch is a plastic (polyethylene or polyvinyl chloride) film. Although it can play the role of heat preservation, water retention and fertilizer preservation, but at the same time, it has many negative effects. [0003] For example, after the mulch film is placed, it needs to be recycled, but the recycling is done manually, which makes it difficult to recycle and causes high recycling costs; at the same time, the mulch film that has not been recycled is not easy to degrade. According to current research, it takes about 300 years for the polyethylene mulch film to completely decompose. time, which caused serious white pollution [0004] In addition...
