Cold winter vegetables precautions
First, we must improve the ability of vegetables to resist disease. There are two methods: 1. Foliar application of new high-fat membranes to supplement plant growth requirements and improve plant resistance to disease. Under normal circumstances, potassium dihydrogen phosphate can be sprayed 300 times or 1000 times more foliar fertilizer. For plants with weaker plant growth, a 500-fold increase in the number of nucleotide leaf foliar sprayed with a 800-fold solution of the new high-fat lipid membrane was used for regulation. 2. Promote root growth, increase the absorption and utilization of nutrients, and ensure the normal growth of plants. Second, we must strengthen environmental regulation. There are three methods for this: 1. Planting lines can be used to cover the film and the operation line to cover the wheat straw, or the whole shed can be sprayed with a new high-fat film, and then the cover film can be used to reduce the evaporation of soil moisture and reduce the humidity inside the greenhouse. 2. It is possible to hang a light curtain on the back wall to enhance the light intensity in the shed, increase the temperature inside the shed, and avoid the unpleasantness of the field and induce disease. 3. The method of releasing air twice can be adopted to exclude the moisture in the shed, while eliminating harmful gases in the shed and supplementing the carbon dioxide concentration in the shed. Third, we must rational use of chemical agents. In a high-humidity environment, spraying often increases the humidity in the greenhouse, which is not conducive to the prevention and treatment of diseases. Especially in the case of cloudy days, the effect of spraying and preventing disease will be very poor. Therefore, the combination of spraying and fumigation should be adopted to prevent and control the disease. Disease. Such as the prevention of gray mold and sclerotinia disease, can be used net saccharomyces, spray mothionine method for comprehensive prevention and treatment. However, in the net use of smoked bacteria must be based on the different crops, pay attention to the control of smoke time. If smoked on legume crops or eggplants, 200 grams of sclerotia are used in the mu. The time for smoking should be controlled within 6 to 8 hours. If the smoke is smoked for a long time, it is prone to injury.
