Summer Nursery Management Points
Summer and autumn are the seasons when the seedlings grow most prosperous. It is also the seedlings that need careful management. In the process of nurturing strong seedlings, the following points should be correctly grasped: 1. In order to timely irrigate the fast-growing period of seedlings, it is necessary to adopt a large number of methods for irrigation. Each irrigation should be thoroughly filled and well-distributed. Pay attention to prevent scouring seedlings and injuring seedling stems and roots. In the later stages of seedling growth, irrigation is generally not required except for special droughts. 2. Weeds should be cleared and weeded after each rainfall or irrigation. Withdrawing the seedlings inconveniently loosens the soil. The weeds can be removed from the seedlings and a layer of fine soil can be removed from the bed to prevent the roots from being exposed. Loose soil will be deepened gradually, but it will not hurt seedlings or pressure seedlings. Manual weeding combined with loose soil, such as the use of herbicide herbicide, but the first test to avoid phytotoxicity. 3, flood control and antisepsis choose to do seedlings plots, generally more low-lying, combined with more summer and autumn rain, once the seedlings affected by the stain, the seedling growth, timely impact on the garden. Therefore, before the arrival of the rainy season, drainage and drainage ditch matching systems should be excavated in advance, and timely drainage and drainage in the rainy season. 4. The top-dressing fertilizer for scientific top dressing should use available fertilizer to open the ditch between rows and apply the fertilizer to the ditch, then cover the soil. It is also possible to dilute the fertilizer and fully spray it on the seedbed (ridges, ridges) and then rinse the seedlings with water. Topdressing time can be done in the growth of lateral roots. Coniferous species should stop topdressing nitrogen fertilizer about 30 days before the top of the seedlings; Yiyang and other broad-leaved species should no longer be fertilized after “early autumn†to prevent seedling shooters. 5, control the lateral roots of broadleaf cuttings seedlings, to control less lateral roots, timely picking buds, in addition to earthworms. 6. Disease prevention and control pest control nursery should make forecast and forecast of pests and diseases, prevent diseases and insect pests that may occur, and timely eliminate the diseases and insect pests that have occurred.
