And its watering principle is mainly refers to the principle of using several times to water frequently watering. Spring is the key time for watering.. From seedling after germination to before and after the wheat harvest is critical period of water requirement. However, at this time in a normal year is lack of rain and drought season.

In late June 7 month is the peak of growth and development, water amount is larger, but under normal circumstances in this period is the rainy season, when the weather is dry, it must be watered, otherwise it will affect the growth and development, resulting in production.
不过，还需要注意的是秋季以后到土境封冻前，需水量较春季少，不遇到特殊干旱一般不浇水，并且在土壤封冻前—般要烧—次封冻水。
However, also need to pay attention to is after the fall to soil environment before frozen, water less than the spring, not to encounter special drought is generally not watering, and in soil freezing front - like to burn a frozen water.
