In early spring or overwintering, the cultivation of vegetables in protected areas often encounters severe weather, such as rain, snow, cloudy days, and low temperature, which not only seriously affect the growth of plants, but also have a great impact on the flower bud differentiation of fruits and vegetables, and cause fruit and fruit drop. Malformed fruit has a great influence on the overall yield of vegetables. Poor management can lead to the production of a crop of vegetables. If you want to grow good vegetables, you must strengthen the management of low-temperature and even cloudy vegetables.
Low temperature even cloudy sky vegetable smoke shed to prevent victimization. The normal use of the aerosol in the greenhouse can achieve good results in 7-8 hours. If the smoking booth is too long, it is easy to cause damage to the vegetables. The leaves are yellow and dry and affect the normal growth of the fruit. When listening to smoked sheds, pay attention to the weather forecast and ensure that ventilation is available on the next day. If the weather is bad the next day, it is best not to smoke the shed.
