How to spray water when planting garden trees at high temperature in summer?

In summer, the temperature is high, the water evaporates quickly, and the soil is prone to water shortage. When the seedlings suffer from drought, they should be irrigated by water diversion or artificial watering in time to soak the seedbed and keep the soil moist.

For common tree species, the soil should be kept moist, and the appropriate irrigation amount should be determined according to the level of groundwater level and rainfall.

Fast-growing seedlings need adequate water supply; The newly planted seedlings should be watered enough, which can be watered for 2-3 times continuously.

Sandy soil with poor water retention capacity should be watered more; Saline-alkali land should be watered with open water. After watering, loosen the soil in time to save water; Watering with moderate humidity can increase the absorption of seedling roots; Adhere to the principle of "seeing dry and seeing wet". In the late stage of seedling growth, except the weather is particularly dry, irrigation is generally not or less. Shading in summer is also very important, and the temperature is too high, which is not conducive to seedling growth. After shading, the surface temperature can be reduced by about 65438 00℃. Therefore, where conditions permit, the seedlings should be shaded to facilitate their growth.

For shade-tolerant seedlings and seedlings that have just been cut and transplanted, shading should be carried out according to specific conditions to reduce the adverse effects of high temperature. Shading nets can be used to reduce the temperature and reduce water evaporation. According to the types of seedlings and their own characteristics, shading nets with shading rate of 40% ~ 60% are generally selected.
