First, timely irrigation, keep the soil moist in summer, high temperatures, rapid evaporation of water, the soil is easy to lack of water. When the seedlings are affected by drought, they should promptly divert irrigation or artificial watering, soak the bed and keep the soil moist. Second, loose soil and weeding should be timely after each rainfall or irrigation, timely cultivating loose soil and weeding, spreading seedlings inconvenient to loosen the soil, can remove the weeds between the seedlings, and then spread a layer of fine soil on the bed, Prevent roots from getting windy. The cultivating loose soil should be gradually deepened, but do not hurt the seedlings and pressed seedlings. Do not touch the roots of the seedlings when loosening or weeding. According to experiments, the sunny noon loose soil is 8°C or more higher than the surface temperature without ripping. Therefore, it should not be loosened and weeded at noon on high temperatures and droughts at noon. It is better to choose to start early, late or after rain on a cloudy day. Third, the method of fertilization should be properly applied when the fertilization can not be too high, one can not be applied too much. In the morning and evening, water or light water and fertilizer must not be used to spread fertilizer between seedlings. Application of fertilizer can be done after loose soil and weeding. Fourth, pay attention to doing a good job of pest control summer seedlings prone to blight, root rot, eat leaves, food bud pests and other pests and diseases. It can be used to prevent and cure Rhizoctonia solani, root rot when spraying Bordeaux mixture, thiophanate-methyl and other drugs; it can be sprayed with chemicals such as trichlorfon when eating leaf or food bud pests; underground pests such as scarabs, cockroaches, cockroaches, etc. can be used. Trichlorfon and dimethoate sprays can also be captured manually. Fifth, and time seedlings, Dingmiao seedlings should be selected after the rain or irrigation. Seedlings that are too dense, poorly grown, poorly developed, injured, and pest-infested, and that affect the growth of most of the surrounding seedlings are to be excluded. For fast-growing broad-leaved trees such as camphor, eucalyptus, etc. For slow-growing coniferous species such as cypress, etc., it is not appropriate to set the seedlings prematurely, and the seedlings can be seeded after 2-3 times. After the seedlings, it is best to use the diluted manure water to improve the survival rate of seedlings. 6. Shading work is also critical The temperature is too high and it is not conducive to the growth of seedlings. After shading, the surface temperature can be reduced by about 10°C. Therefore, seedlings should be shaded in places where conditions permit, to facilitate the growth of seedlings.
