【Abstract】 The experimental results showed that the post-premature of tomato with film mulching culture was relevant to applying fertilizers. The higher application ratea of fertilizers may increase the effective nutrients 9f soil and improve the nutrition conditions of plant to promote it growing well, the average yield of plots reached 75. 2kg. converting into 3008kg. per Mu,increased 16. 89% than that of the contrast;the plots of low fertilizers application the yield decreased 3. 76% than that of contrast.更多还原
