First, the appropriate shading For shade tree species and flowers and seeding time too late seedlings, in the early stages of growth should be used to reduce temperature measures to reduce the adverse effects of high temperature heat damage, such as shade shelter. Conditional shade net can be used to avoid sunburn hazard seedlings.
Second, timely loose soil weeding in each rainfall or irrigation after weeding weeding. Shallow soil should be shallow to keep the topsoil loose to facilitate seedling growth. Weeding should be "in addition to early, except small, in addition to", spreading seedlings inconvenience weeding and loose soil, weeds can be pulled out between the seedlings, and then spread a layer of fine soil on the seedbed to prevent root exposure. Loose soil should be deepened gradually, but care should be taken not to hurt the seedlings or press the seedlings.
Third, if the land for flood prevention is relatively low, drainage ditches should be dug ahead of time before the arrival of the rainy season. In the summer drought, irrigation is an important measure to cultivate strong seedlings. When the weather is dry, it is necessary to pay attention to watering and ensure that the seedbed is moist.
Fourth, reasonable top dressing Fertilizer commonly used quick-effect fertilizer or decomposed human waste. The common quick-effect fertilizers in nurseries are grass ash, ammonium sulfate, urea, and superphosphate. The frequency of fertilization should be more but each dose should be less. General seedling growth period can be topdressing.
