浇冻水就是在土壤封冻之前浇灌一次足水,这对果树和越冬作物有很大的好处,是来年增产丰收的一个关键措施。在冬季低温干燥时间较长的情况下,首先可使土壤保持比较稳定的温度,提高抗寒能力,防止冻害。第二、保持果树根系活动有充足的水分供应,集累更多的养分,为返青期地上部生长打下基础。第三、充足的水分,可使土壤的冰冻程度增大,因而在解冻时,土壤变得疏松,促使根系生长良好。
To pour cold water is to water the soil one full time before it is frozen, which is of great benefit to fruit trees and winter crops and is a key measure to increase yield in the coming year. In the case of a long time of low temperature drying in winter, the soil can be kept at a relatively stable temperature for the first time, improving the ability of cold resistance and preventing frost damage. Second, to maintain sufficient water supply to the root activity of fruit trees, to accumulate more nutrients and lay the foundation for the growth of the upper part of the rejuvenation period. Third, adequate moisture can increase the degree of soil freezing, so that when thawed, the soil becomes loose and the root system grows well.
