Method of multiple use of plastic film

Covering cultivated crops with mulch can make it early mature, high yield, and improved quality. However, in the actual production process, most of the mulches have to be discarded due to improper use. In order to increase the utilization ratio of plastic film and reduce production investment, it is advisable to use the plastic film several times. The main methods and methods are as follows;

First, the use of wheat and melon from the end of November to use the new film covering wheat (2512,6.00,0.24%), to the second year of spring in mid-March for the film period of wheat, and then will peel off the film in early April watermelon.

Second, wheat and vegetables are used repeatedly from the end of November to mid-March of the following year. Wheat is covered first, then the spring vegetables are covered, the film is removed about 10 days, and the summer vegetables are covered again in early April, and some still cover autumn vegetables. As long as you carefully remove the plastic film, you can generally use it four times.

1. The mulching film removes and covers different crops several times

1 winter wheat - cabbage - cucumber (or tomato), 2 winter wheat - raw bamboo shoots - tomatoes (cucumber), 3 winter wheat - cumin - bell pepper, 4 winter wheat - radish - bok choy - cowpea, 5 wintering garlic - radish - cowpea - tomatoes, 6 winter spinach - water radish - cumin - tomatoes.

In the above example, radish, fennel, and other fast-growing vegetables can be mixed with each other, while the third-fruited guava, fruit, and vegetables can be replaced with each other.

2. The plastic film covers the ground, only after changing the crops such as covering the film, the first planted cabbage, planted sweet peppers, autumn and then planted bamboo shoots or beans covered in spring, cover the cucumber in autumn.

3. First, use as a plastic film, then use a plastic film to cover the wheat in a small shed. After peeling off, use a plastic film to build a small shed to grow vegetables such as cowpea. It is also possible to cultivate cucumbers in small greenhouses with plastic film in greenhouses. After peeling off the plastic film, the plastic film can be used for the cultivation of vegetables such as tomatoes.
