1. Prevention of vaporization heat: in non woven film(China non woven mulch custom) mulching cultivation, more holes are drilled and planted, and the seedlings are often burned by vaporization heat. This is because after mulching, the water in the ground soil layer will vaporize and form water droplets on the surface under the film. When the planting hole is exposed, the vaporized hot air under the film will rush out of the hole. When the temperature near the seedling is very high, especially at noon on a sunny day, it will often burn the seedling, or cause "heat damage" to the root neck or basal leaves of the vegetable, resulting in the lack of seedlings and ridge cutting or affecting the normal growth of the plant. Therefore, special attention should be paid to the cultivation of rhizosphere planting holes. After the seedlings are planted, the planting holes should be sealed with fine soil immediately, so that they cannot be exposed at all.

2. Heavy application of base fertilizer: it is difficult to apply fertilizer after mulching with non woven film, and the soil temperature rises rapidly, the crops grow vigorously, and the fertilizer demand increases. Therefore, heavy application of base fertilizer should be carried out before mulching with non woven film.

3. The bottom water should be watered enough: the soil moisture surface must be watered thoroughly before the non woven film covering, so that the soil in the soil moisture contains sufficient water. However, the mulch film cannot be covered immediately after the water surface is watered, otherwise the soil moisture in the film will be too high, forming a "coated soil". The mulch film can only be covered after the water surface soil "absorbs sweat".

4. Cover the non woven film(agricultural nonwoven fabric wholesaler) tightly: the non woven film must be stretched, paved without wrinkles, and closely adhered to the bed surface, and the surrounding of the film shall be compacted with soil. After planting, avoid damaging the non woven film during agricultural operation. If the non woven film breaks or is not tight around, it should be compacted with soil in time, which can fully ensure the thermal insulation and moisture retention effect of the non woven film.
