Problems solved by technology

In the process of use, it is generally tiled, with the silver side facing up and the black side on the ground. The silver and black double-sided plastic film has the advantages of water retention, soil retention, fertilizer retention, weeding, and effective control of soil humidity and temperature. The white mulch film is transparent, the temperature inside the film is high, and the problem of easy seedling death is avoided. It also avoids the problem of ordinary black mulch film heat radiation and affecting the growth of seedlings under the film. It makes full use of the heat radiation of ordinary white mulch film to raise the temperature and reflect light and the moisture retention of ordinary black mulch film. Herbicidal performance

Embodiment Construction

[0014] The present invention will be further described below in conjunction with specific examples.

[0015] The mulch film of the present invention is a double-sided mulch film whose front reflectivity is 45% to 50% silver, and the back is black. Purchase the following ingredients from the open market:

[0016] High reflective silver masterbatch 2006G;

[0017] American Cabot black masterbatch 6251;

[0018] Linear low density polyethylene: 7042, 7042N;

[0019] Low density polyethylene high pressure 2426H;

[0020] American Mobil Metallocene 1018HA.

[0021] The preparation method of film of the present invention, comprises the steps:

[0022] 1) Prepare the special silver masterbatch and the special black masterbatch respectively containing the highly reflective silver masterbatch and the black masterbatch respectively according to the following parts by weight ratio;

[0023] The special silver masterbatch includes the following raw materials by weight: 9 parts of hi...

Abstract

The invention relates to a mulching membrane and a preparation method thereof. The positive side of the mulching membrane has a silver colour with a reflectance rate of 45%-50%, and the back side of the mulching membrane has a black colour, and the mulching membrane comprises the following raw materials during preparation: 8-15 parts of highly-reflective silver master batches, 8-15 parts of black master batches, 62-70 parts of linear low density polyethylene, 3-9 parts of low density polyethylene, 3-10 parts of a metallocene, and 2-6 parts of anti-aging special master batches. Besides the advantages of water retention, soil conservation, fertilizer conservation and effective control on soil moisture and temperature, the silver and black double-side mulching membrane also has the following advantages: the light transmittance is 10%, the reflectance rate is 45%-50%, on one hand, the silver positive side can have a repellent effect on aphids, and on the other hand, existed reflected light enables fruits growing below and fruit parts back to sunshine to be indirectly illuminated by the sun, so that the ripening period is shortened, fruit peel coloration is promoted, and the sugar content and the nutritional value of the fruits are improved. The black back side can prevent sun penetration, and is beneficial to inhibit weed growth.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a mulch film and a preparation method thereof. Background technique [0002] Since the nineties of the 20th century, the use of mulching technology to plant various fruits and vegetables in my country has developed rapidly. On the one hand, the use of agricultural mulch can preserve water, soil, and fertilizer, effectively control soil humidity and temperature, and increase crop yield; on the other hand, the mulch close to the ground can also reflect sunlight to a certain extent to the place where the fruit faces away from the sun , so that the fruit coloring is more uniform. However, ordinary white mulch has a heat radiation rate of 80% to 90%, high light intensity, can increase the ground temperature by 2 to 4°C, and has excellent thermal insulation performance. However, the high light transmittance of the mulch film will make the temperature inside the film relatively ...
