地膜覆盖栽培番茄后期早衰的研究

A study on final premature decay of tomato with film mulching culture

该试验结果表明,地膜覆盖栽培番茄的后期早衰和施肥有关。施肥量多,土壤有效养分和植株的营养状况较好,植株生长发育也较好,小区平均产量最高,达75.2kg,每公倾合4.512万kg,比对照增产16.89％。施肥量低的处理,比对照减产3.76％。

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.
