Matters needing attention when raising seedlings in smart greenhouses

(1) Prevent overgrowth. In the high temperature season, the vegetable seedlings are prone to grow up in the smart greenhouse. Use a watering can to cool down in the morning and evening, and divide or thin the seedlings in time to increase the nutrient area of the seedlings. For cucumbers, tomatoes and other fruits and vegetables, chlormequat can be sprayed to control the lengthening of seedlings. Make the seedlings thick, thick green leaves, thicken the leaves, promote the differentiation of flower buds, and increase the rate of healthy seedlings;

(2) Selected plots The intelligent greenhouse for vegetable seedlings in summer should be selected for plots with high terrain, good soil permeability and water retention, which can drain waterlogging in case of heavy rain, and can be watered in case of drought. Never grow seedlings in the smart greenhouse plot where the same stubble of vegetables has been planted in the previous crop to avoid soil-borne disease hazards, and avoid using plots with serious underground pests to grow seedlings;

In the construction of smart greenhouses, the choice of protective film is very important. It is not only strong, but also can affect the interior of the greenhouse from regional climate disasters. Therefore, in the construction of smart greenhouses, you need to choose the appropriate protective film. NS. So how should the protective film of the smart greenhouse be selected?

1. Good dust-proof effect. Good quality protective film, its surface coating can hinder the adsorption of dust, and will not settle in the film, which greatly improves the transmittance of the film, and there is no need to worry about cleaning problems during use, and it can be rainy. After washing with rainwater, the film is as new as before.

2, anti-fog and no water droplets. The anti-fogging dripping of the best quality protective film is long-lasting, and the protective film of the granular coating can extend the anti-fogging and drip-free period indefinitely.

3. Strong stretching ability. Stretching ability is also a way to verify the quality of the protective film. When purchasing, you should choose a protective film with strong stretching ability. Its stretching force is five to ten times that of ordinary films. This high-strength characteristic mainly depends on the film. The nylon material inside.
