Abstract:Rice production in aerobic soil with mulching is one of the most important cropping systems for water-saving agriculture. In this system, the rice plant (not upland variety but traditional paddy rice variety with high yield potential) is grown during whole growth stage in soil with water content being 70%~90% of water holding capacity (WHC). The total shift of the growth environment from traditional waterlogged to aerobic conditions greatly changes rice growth, i.e. the characteristics of rice growth and de...
