How does growing rice prevent premature aging?

What causes premature senescence of rice? How to prevent premature senescence by planting rice? There is no understanding of the netizens to help introduce that rice premature senescence will lead to a substantial reduction in rice production, the farming network sorted out the causes of rice premature senility and prevention methods, listed below for netizens' reference. The cause of premature senescence of rice: premature senescence refers to the premature decline of important functions in leaves, stems and other parts of rice in the late growth stage, weakening the photosynthesis of functional leaves, reducing the source of irrigation materials, and the phenomenon of premature senescence in some plants. The premature senescence of rice is due to the over-prosperous growth in the early stage, which deepens the contradiction between the population and individuals in the later stage, and accelerates the senescence of roots and leaves. Another reason for premature senility is improper management of water and fertilizer in the later stage, early water cut-off, insufficient supply of nitrogen and phosphorus, lack of nutrient supplement for plant growth, poor soil permeability, more hypoxia and toxic reducing substances, resulting in poor root development in the later stage of rice, weakening the ability to absorb nutrients, resulting in the weakening of aboveground growth. Methods of planting rice to prevent premature senescence: first, scientific water management, shallow water irrigation from full heading to filling stage, increasing temperature and promoting ripening, and intermittent irrigation from milk stage to yellow ripening period. Method 2. Rational fertilization should be applied to rice to prevent de-fertilization in the middle stage, and spike and grain fertilizer should be skillfully applied in the later stage to improve photosynthesis.
