Embodiment 1

[0018] Embodiment 1 Preparation of liquid mulch (weight percent)

[0019] Add 20% methyl silicate, 1% sodium hydroxide and 79% water into the stirring tank, and stir until the sodium hydroxide is completely dissolved.

Embodiment 2

[0020] Example 2 Preparation of liquid mulch (weight percent)

[0021] Add 28% of methyl silicate, 5% of sodium hydroxide and 67% of water into the mixing tank, stir until the potassium hydroxide is completely dissolved, and then add an appropriate amount of methyl red and thymolphthalein.

Embodiment 3

[0023] The test site is located in Xinjiang, and the area of ​​each treatment plot is 4.5×6=27m 2 . Level the land before the test, add the product to be tested according to different effective dosages into an ordinary sprayer, dilute with water, and spray evenly on the soil surface. Assuming that the tested products were blank control and 1% (v / v) liquid mulch treatment (1L / m 2 dosage). Soil was taken before and after each test to measure the total salt of 0-20cm and 20-40cm, and soil was taken at two equal distances from each treatment plot. One day after the liquid mulch was applied, water was applied to pressurize the alkali, and after another week, the total salt content of different soil layers was measured respectively as mentioned above.

Abstract

The invention discloses a liquid mulching film and a preparation method thereof. The liquid mulching film comprises components with the weight percentages as follows: 20 to 30 percent of methyl silicate, 1 to 5 percent of strong base and the rest percent of water. The liquid mulching film achieves the effects of water evaporation prevention and alkali decrease by utilizing a hydrophobic principle of the methyl silicate, and does not contain a film forming agent and a surface active agent. The preparation process is simple and facilitates mass production. An end product obtained after the liquid mulching film is decomposed is silica, which is a product of the nature and cannot cause damage to the environment. The liquid mulching film disclosed by the invention can be directly diluted by using water and acts the surface of oil. The preparation method disclosed by the invention is simple and convenient to operate and can be applied to the fields of agriculture, forestry and the fruit industry of arid areas, semiarid areas and high-saline-alkali areas.

Description

technical field [0001] The invention relates to a novel liquid mulching film and a preparation method thereof. Background technique [0002] Film mulching is an agricultural technology applied in the middle of the 20th century, with the development of the plastics industry, especially the emergence of agricultural plastic films, some industrially developed countries use plastic films to cover the ground for crop production. Our country conducted experiments in 1978, and began to conduct experiments, demonstrations, and promotions in some areas in 1979. Due to the remarkable effect of covering production, the film covering production enlightenment and the whole country. Film mulching is a new agricultural technology that is suitable for my country's national conditions, has wide adaptability, and is widely used to promote early maturity, high yield, and high efficiency of cover crops. The use of plastic film mulching technology is an effective measure to increase agricultur...
