Qiuyu vegetables are now entering the peak of planting, and rapid seedlings are the key to breeding strong trees. What should be paid attention to in the management of the slow seedling period? First, scientific watering Many vegetable farmers often continue to water the plants in order to prevent the high temperature and drought of the soil after planting. Most of them use large water flooding. Although watering can lower the ground temperature, the soil moisture is saturated for a long time, which will affect the roots. In the end, it will cause wounds, and serious root disease will occur. Therefore, do not flood the water. Second, anti-high temperature burning seedlings This kind of situation often occurs in the case of cloudy and cloudy conditions. After a cloudy day, the amount of evaporation is large, and the roots are insufficiently absorbed to cause burning. If such a situation occurs, a small amount of shading and cooling will be carried out in time, and the leaves will be sprayed with foliar fertilizer. Third, rainproof into the shed In the high temperature season, the vents of the greenhouses are widened, and the rainwater can easily enter the shed. At this time, the amount of bacteria in the rainwater is large, which is very harmful to the seedlings. Once rainwater is poured into the shed and the roots of the seedlings have just been planted, the chance of root disease is greatly increased. Therefore, it is necessary not only to strengthen the ventilation of the shed, but also to prevent rainwater from entering the shed to affect the slow seedlings. Fourth, the application of bacterial fertilizer to promote slow seedlings The biological bacteria have great protection and growth promoting effects on the root system. When the vegetables in the slow seedling stage are watered, the appropriate amount of biological bacterial fertilizer can promote the rapid rooting of the seedlings and inhibit the occurrence of root diseases. Five, use drugs with caution During the slow seedling period of vegetables, due to the high temperature and high humidity in the shed, the resistance of vegetables to the medicinal agent is weak. Therefore, some medicines cannot be used or cannot be used according to the concentration at the flowering and fruiting stage, such as copper preparation, which is easy to inhibit plant growth.
