Embodiment 1

[0027] Take 580 parts of Shengli decompression residual oil, 420 parts of water, 8 parts of surfactant "octadecyl primary amine", 6 parts of stabilizer "ammonium chloride", 2 parts of protective agent "corn starch", and herbicide "grass Nine parts of "Naisi" are emulsified on the emulsification device. The formula not only has the function of mulching, but also has the function of weed control. The specific composition is shown in Table 1, and the properties of the product are shown in Table 2.

Embodiment 2

[0029] Take 600 parts of Xinjiang vacuum residue, 400 parts of water, 10 parts of surfactant "C10 naphthenic triamine", 2 parts of stabilizer "magnesium chloride", 0.2 part of protective agent "hydroxyethyl cellulose", fertilizer "ammonia water "10 parts, insecticide "1605" 5 parts, emulsified on the emulsification device. In addition to the function of mulching film, this formula also has the functions of fertilizer and insecticide. The composition is shown in Table 1, and the properties of the product are shown in Table 2.

Embodiment 3

[0031] Take 650 parts of Daqing propane deoiled asphalt, 350 parts of water, 3 parts of surfactant "stearyl propylene diamine", 2 parts of stabilizer "calcium chloride", 10 parts of protective agent "soluble starch", water retention agent "polymer Acrylamide" 4 parts, herbicide "Benben" 5 parts, fertilizer "ammonia water" 6 parts, emulsified on the emulsification device. In addition to the function of plastic film, this formula also has the functions of water retention, weed control and fertilizer.

Abstract

A liquid-state ground film for improving soil and preventing loss of water and soil contains goudron and / or asphalt, water, cationic surfactant, stabilizer, protecting agent and additive. Its advantages are low cost, and high filming performance and stability.

Description

1. Technical field [0001] The invention relates to a liquid mulch film and a production method thereof. 2. Background technology [0002] In the process of agricultural production, in order to make crops emerge early, mature early and increase yield, the past experience is to cover plastic mulch after planting to increase ground temperature, maintain humidity, promote early germination and emergence of crops, and achieve early maturity and increase yield. However, with the use of plastic mulch, it is necessary to manually remove the plastic mulch when the seedlings first emerge from the soil, and it is necessary to grasp the timing. If it is too early, it will not have the effect of moisture conservation, and if it is too late, it will cause the death of the seedlings. The emergence time of the same crop is also different, so it is more labor-intensive to use plastic mulch. In addition, plastic mulch is not easy to degrade and not easy to recycle. Remaining in the soil will...
