The experimental results of two years from 1998 to 1999 show that the dry film mulching has significant water saving and fertilizer saving effects. The long tillering time and strong tillering of rice are favorable to increasing the effective panicle number and increasing the yield. At the same time, the preliminary cultivation technology of water-saving and high-yielding cultivation of rice lamina was put forward.
