Abstract:Laying impoisonous polyethylene membrane of 2 μm thick in the deep soil 30 to 40 cm far from the ground. After planting, we make 0~10 holes per m2 according to the soil texture and percolation, i.e. we make no hole in the bottom membrane if the soil is sandy and water can percolate easily, and we make proper amount of holes if the soil is clayey and water can’t percolate easily. Perfect result has been achieved through experiment and improvement last for three years. Comparing with the control, this practice can cut water use by 60.3% and the fertilizer use by 32.2%. At the same time, total roots increased 22.2% and roots in tilth top soil increased 32%, each plant produced extra 3.9 effective tillering and 17.2%of effective ears, rice matured 5 days earlier and average yield increased 20%.
