Wheat grown after the rice harvest is very difficult to sow in time, because rice is harvested too late. In addition, the soil after rice harvests is hardened and impervious, not good in functions of physics and chemistry, so the production of wheat grown after rice harvests is low and unstable. To change the situation, we advance a test of replacement of rice by dry rice. The result displays that wheat grown after dry rice harvest has increased by 100 kg, because dry rice ripens 10 day earlier than wheat grown after rice and the function of soil can be regulated in physics and chemistry features.
