Greenhouse vegetables autumn and winter period management measures
Into the autumn and winter season, the temperature began to drop. In order to prevent the arrival of severe weather, reduce the loss of greenhouse vegetables, increase vegetable production, greenhouse production management should pay particular attention to the following issues.
Pay attention to weather changes and advance the maintenance of facilities and equipment. Into the fall and winter season, warmth and antifreeze are basic requirements for the production of vegetable facilities. Otherwise, once it is chilled, it will cause irreparable damage. Cope with the maintenance and repair of greenhouses prior to entering the winter, strengthen the overhaul of coverings such as sheds, straws, and insulation, and increase the insulation film if necessary. Reinforce the shed body and treat the shed where it is not strong enough to prevent the shed body from collapsing due to freezing snow. Drain the drainage around the shed body to prevent rain and snow from accumulating, causing damage to the shed body. The maintenance of the power supply line shall be carried out in a timely manner, and the aging line shall be replaced so as not to be affected by the wind, ice, and other weather, resulting in the failure of the greenhouse operation.
Effectively regulate the greenhouse environment and strengthen water and fertilizer management. In autumn and winter, the outdoor temperature dropped sharply, requiring insulation and heating measures to solve the temperature problem. The greenhouses in autumn and winter usually have higher humidity and weaker light, which requires a proper extension of the watering interval. At the same time, the use of fertilizers should be appropriately increased, and in combination with rooting fertilizers such as roots, roots, etc., be applied together to promote more rooting of vegetables. In order to reduce the occurrence of the disease, watering time should be selected as sunny as possible to ensure that the plants are dry at night. In order to improve the cold-resistance and stress-resistance of vegetables, the leaves can be sprayed with bi-protecting, ice-protecting, and love-absorbing. In order to extend the lighting time, the greenhouse can be equipped with plant solar lights.
Strengthen pest control. In the fall and winter season, the greenhouse environment is closed tightly, the greenhouse humidity is relatively high, and pests and diseases are prone to occur. Therefore, strengthening the prevention and control of greenhouse pests and diseases is the focus of greenhouse management. Priority should be given to pest control nets, yellow panels, and high-temperature stuffy sheds to prevent and control. Spraying is best done at noon on sunny days. At night, aerosols such as chlorothalonil, procymidone and isoprocarb can be used for fumigation.
