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:
The use of wheat and melon: that is, from the end of the winter in winter to cover the wheat with a new film, to the second year of spring in mid-March for the film covered with wheat, and then the film will be peeled off in early April and then cover the watermelon.
Wheat and vegetables are used multiple times: from the end of November to mid-March of the following year, wheat is covered first, then covered with spring vegetables, the film is removed about 10 days, and then the summer vegetables are covered in early April, and some still have autumn vegetables. As long as you carefully remove the plastic film, you can generally use it four times. The mulching of the mulching film covers the different crops several times. 1 Winter wheat ─ Cabbage ─ Cucumber (or tomatoes); 2 Winter wheat ─ Raw bamboo shoot ─ ─ Tomato (cucumber); 3 Winter wheat ─ cumin ─ sweet pepper; 4 ─ ─ winter radish - radish - cabbage - Bean ;5 Overwintering garlic ─ ─ ─ Robert ─ ─ cowpea ─ tomatoes; 6 winter spinach ─ water carrots ─ cumin ─ tomatoes.
In the above example, radish, fennel and other fast-growing vegetables can be used for mutual adjustment. The third-fruited melon, fruit and vegetables can also be replaced with each other. The plastic film covers the end and only changes crops. Such as covering the film, the first planted cabbage, after planting sweet peppers, autumn and then planted bamboo shoots or beans covered in spring, cover the cucumber in autumn. First for the film, and then for a small arch. First cover the wheat with a plastic film. After peeling off, use a plastic film to build a small shed to grow vegetables such as kidney beans. Can also be used in the greenhouse with a small shed for greenhouse cultivation of cucumber, peeled off the plastic film and then cover for the cultivation of tomatoes and other vegetables.
