Cold-proofing techniques for greenhouse planting in winter

1. Spraying foliar fertilizer: The temperature is low in winter, the sunlight in the greenhouse is weak, and the absorption capacity of crop roots decreases. We can spray potassium dihydrogen phosphate solution on the leaves to increase the sugar content and hardness of the leaf flesh. Improve the cold resistance of plants and alleviate the degree of freezing damage. Or mix rice vinegar with sugar and superphosphate to make 100-300 times liquid and spray it on the leaves.

2. Cultivation heat preservation and cold protection: In winter, the greenhouse floor is constrained, and the heat entering the cultivated layer during the day is restricted. The soil heat storage is low. In addition, the compacted soil has large and deep cracks and poor aggregate structure. Frost damage. Shallow cultivating while ventilated can break ground cracks, so that it can control the transpiration of groundwater and take away heat, and it can keep warm and cold and protect seedlings.

3. Covering and warming: to maintain the airtightness of the greenhouse film, build a middle shed in the shed or add thermal insulation materials on the small arch shed, cover the film at night, and cover the grass thatch on the film; cover the mulch film in the greenhouse and outside the greenhouse Use grass thatch and plastic film as an apron around the bottom to reduce the invasion of cold air at the bottom; at the same time, pay attention to blocking the gaps everywhere and minimize the heat dissipation of the gaps. Set up a wind barrier, and the quilt in the greenhouse is used as a wind barrier to prevent wind and cold.

Product introduction

Multi-span film greenhouse is a greenhouse with film as the main transparent covering material. It is usually divided into single-layer film greenhouse and double-layer film greenhouse. The main structure of the multi-span film greenhouse is a round arch. Thin-film greenhouses have the advantages of low cost, economical and practical, beautiful appearance, convenient installation and maintenance, sturdiness and durability. Single-layer thin-film greenhouses are mostly used in spring and autumn or areas with mild climate; double-layer thin greenhouses are mostly used in northern regions.

Supporting system

It can be equipped with external shading system, internal shading system, thermal insulation system, natural ventilation system, fan wet curtain forced cooling system, micro mist cooling system, irrigation system, CO2 supplement system, light supplement system, fertilization system, Heating system, circulation fan system, seedbed system, computer semi-automatic and automatic control system, top spray system, etc.
