Reasons: During the late growth period of rice, the organic nutrients produced by the leaves stay in the vegetative parts, presenting early love qing, leading to greediness. Due to the reasons of low temperature, cold damage and drought, resulting in the normal growth and development burden, reproductive growth delayed, nutrients can not be normal to the direction of reproductive growth, photosynthesis intensity and light time is not enough, aggravate greed, excessive nitrogen fertilizer or late application, nutrition Late growth of the body is too prosperous, but also prone to greediness; planting density is too large, poor ventilation and light transmission, stems and leaves are too lush, but also prone to greediness.
Prevention: Reasonable irrigation, drought prevention, reasonable dense planting, timely application of appropriate amount of nitrogen fertilizer, not too much to prevent excessive growth, leading to greed.
