Key points of water management in broccoli

In the slow seedling stage, the seedlings should be watered in time to promote the return of seedlings. The water should be properly controlled after survival, which is beneficial to the depth of the root system. In the middle and later stage of growth, that is, the peak growth period of leaf clusters and the period of flower bud development, the water demand is relatively large, which should be watered in time in dry years, usually once every 4-5 days, and the border surface can be covered with straw or weeds to reduce water evaporation. Typhoons and torrential rains are frequent from July to September, so it is necessary to clear the ditches and drain them in time so that there is no water in the ditches when the rain stops.
