In general, the growth of seedlings is large in the early stage of growth, seedlings grow vigorously, and high-quality seedlings can be obtained in the later period; conversely, poor growth in the early stages can cause leggy phenomenon in the later period of seedlings. Therefore, grasping the management of nursery stocks, especially early management, is extremely important. In the management process, you should master the following points: I. Seedling Irrigation: Irrigation in the fast-growing period of seedlings should take a large number of methods. Each irrigation should be thoroughly irrigated and well-distributed, and precautions should be taken to prevent scouring the seedlings. In the later stages of seedling growth, irrigation is generally not required except for special droughts. Second, manual weeding: weeding is conducive to the growth and development of seedlings, in each rainfall or irrigation should be carried out after soil, weeding. Spread seedlings and inconveniently loosen the soil, remove the weeds between the seedlings, and then spread a layer of fine soil on the bed to prevent the roots from getting windy. Loose soil should be gradually deepened, fully loose and uniform, not to hurt seedlings, not pressure seedlings; weeding to master the "except early, except small, in addition to" principle, to reach the nursery without weeds. The method of manual weeding is: when the bed is wet, combined with loose soil, remove by hand. Herbicide herbicide should be tested before use to avoid phytotoxicity. Third, timely top dressing: Top dressing use available fertilizer, ditching between the rows, the fertilizer applied to the ditch, and then covered with soil. Fertilizer can also be diluted, sprayed on the seedbed, and then rinse the seedlings with water. The topdressing time can be performed when the seedlings grow lateral roots. Conifer species should be topdressed for about 30 days before the top of the seedlings, and the broad-leaved tree species such as Italian poplar should not be fertilized after the beginning of autumn to prevent seedlings from growing. Fourth, the control of lateral roots: cuttings of broadleaf tree seedlings, to control its less lateral roots. In addition, prevent diseases and insect pests that may occur, and prevent and treat diseases and insect pests that have already occurred.
