What is the correct method and purpose of draining paddy fields for rice?
How do you drain a paddy field for rice? What does it do? Please explain the field-draining method. Draining paddy fields is one of the main technical measures for increasing rice yields and promoting early ripening. 1. Main purposes of field draining. 1) Control ineffective tillering and consolidate effective tillering. When rice tillering has reached a certain number, that is, once there are enough seedlings, in our province, in terms of time, the effective tillering termination period is around the end of June. Early tillers can form panicles, while tillers after the termination period cannot form panicles or only form small panicles. In production, by draining the field, the young tiller buds at higher positions cannot get water and fertilizer and stop growing, reducing nutrient consumption, so that the main stem and large tillers receive more nutrient supply, laying a foundation for strong stems and large panicles.
