Fruit trees winter irrigation attention
The irrigation of orchards in winter can increase soil moisture content, improve the cold resistance of fruit trees, accelerate the decomposition of soil organic fertilizer, and increase soil fertility. First, winter irrigation time Winter irrigation should be carried out before the soil is frozen. However, the average temperature in the 5 cm soil layer dropped to 5 °C, and the soil was frozen at night, and it was the best period for the daytime temperature to rise and thaw. Second, the amount of irrigation water on the same day, the water can all penetrate the ground, deep to the root distribution layer, that is, sapling infiltration of 60 cm, adult trees infiltrated to 100 cm, soil moisture in the field of maximum water holding capacity of 60% -80%. III. Irrigation methods In orchards with adequate water sources and well-watering equipment, it is possible to use irrigation or ring-shaped furrow irrigation. In an orchard with poor water supply and poor conditions, it is possible to set up a flood of water around the perimeter of the canopy. For conditional orchards, drip irrigation and sprinkler irrigation works best. China Agricultural Network Editor
