Agricultural Netn Crop Vegetable Protection Net For Apple Trees Guard Netting

Agronet properties:

The agronets used were made from high-density polyethylene fully recyclable monofilament of 100 denier knitted into a mesh. The nets were white in color with average pore size of 0.9 mm × 0.7 mm. They were ultraviolet protected for extended shelf life with ≈90% light transmittance.

1 Insect net, Chinese cabbage, microclimate effect, Microclimate effect of greenhouses covering different color insect nets and their effects on vegetable growth

The greenhouse is covered with black net, the light transmittance is 633%, and the shading effect is remarkable. The highest temperature in the shed, the black net is 0 3 ° C lower than the control, and the humidity increases.

The top black net and the silver gray net were higher than the control 10~13 °C; the lowest temperature, the black net was 0 9 °C higher than the control, the top black net was 0 2 °C higher than the control, and the silver gray net was lower than the control 0 5 ~ 0 8 °C .

The plant height of the Chinese cabbage covered with the insect net increased, the degree of development decreased, the leaf color became shallow, the leaves became thinner, the chlorophyll content decreased, and the weight per plant was small.

Insect net cover microclimate dish vegetable virus disease

Through the cultivation test of the dishworm insect net, it is clear that the insect net can block the aphid transmission virus, the incidence of no virus disease in the seedling stage is only 1% to 13%; the seedling stage double leaf inoculation is only 7% to 13%;

The incidence of virus cultivation in open field is 95%-100%. The coverage also improves the growth environment of the dish. The sunny day plays a role in shielding the light. At 10 cm above the ground, the surface temperature of the surface and leaves is lower than that of the open field. The humidity promoted the growth of the dish.
