What Is Agricultural Mulch?
Mulching technology is a breakthrough invention made by mankind in the field of agriculture. Invented and applied by Japanese scientists in the 1950s, it was first used for strawberry production. In June 1978, Zhu Rong, the then deputy minister of the Ministry of Agriculture, after visiting Japan and returning to China, introduced the Japanese plastic film mulching technology to the relevant units, and requested to carry out relevant research, thus starting the research and application of China's plastic film mulching technology.
The mechanism of action of plastic film mulching is to effectively improve the growth and development conditions of crops, resist adverse environments, and make full use of Limited light, heat, water and nutrients promote the germination of seeds into the soil, accelerate the growth of roots and shoots, and prolong the effective growth period, so as to obtain the good effects of early maturity, high yield and high quality. Under normal circumstances, mulching with plastic film can increase the average ground temperature during the crop growth period by 3-6°C, increase the accumulated temperature by about 300°C, increase the soil water content of 0-20 cm by 2.6-3. improve.
