Rice filling period is a key period for rice growth. When is rice in the filling stage? Let's introduce Xiaobian to introduce the characteristics of rice filling period. What is the rice filling period? The rice filling period refers to the period from the end of the bud closure to the maturity of the grain. From a biological point of view, this is the process in which the fertilized egg develops into an embryo and the fertilized nucleus develops into an endosperm. From the production point of view, this is the period of final production. At this time, it is necessary to ensure sufficient photosynthetic area and unobstructed material transportation channels. Characteristics of rice filling period 1. The granules forming the ovary begin to elongate on the first day after fertilization. After 6-7 days of flowering, the rice granules can reach the maximum length. At this time, the organs of the embryo are also substantially completed and begin to have germination ability. 8-10 days, the rice grain reaches the maximum thickness. Rice fresh weight grows fastest within 10 days after flowering, and reaches a maximum at 25-28 days. The peak dry weight of rice grains is 15-20 days after flowering, and reaches a maximum at 25-45 days after flowering. 2, mature seeds of mature seeds of rice, generally divided into milk ripe, wax cooked, mature several times. Generally, it blooms for 3-5 days and enters the milky stage. At this time, the starch deposit in the grain is milky white. On this basis, the white emulsion becomes thicker until it becomes a hard waxy shape, and the chaff turns yellow, which is called the wax ripening period. After the wax is cooked, it will enter the ripening period about 7-8 days. At this time, the rice grains are hard and solid, and the back green is white and the rice is over.
