| 摘 要： | 试验研究了地膜覆盖及绿农素喷施对马铃薯生长发育及产量等的影响。结果表明 :马铃薯地膜覆盖比露地 5cm日平均土温提高 3 2 7℃ ,0～ 2 0cm土层含水量提高 1 8个百分点 ,成熟提早 10～ 15d左右 ,商品薯率等经济性状有明显改善 ;绿农素喷施能克服地膜覆盖后追肥难及沙地保肥性差所造成的脱肥、早衰问题。地膜覆盖 +绿农素喷施能大幅度提高马铃薯产量 ,分别较地膜覆盖、绿农素喷施、露地增产 11 93%、 17 2 5%和 2 7 89%。

| Abstract: | The results of experiment show that film mulched potato plays a role in increasing temperature and presevating soil moisture and it can increase temperature by 3 27 ℃ and increase 0～20 cm soil moisture by 1 8% by comparing with uncovered land and also show that film mulched potato ripens early by 10～15days and the rate of commdity and other economic characteristics have improved obviously.Lunongsu sprayed can solve the problems of short of fertilizer and early aging which are caused by film mulched.Film mulched and Lunongsu sprayed can increase potato yield obviously.Comparied with film mulched,Lunongsu sprayed and uncovered,film mulched and Lunongsu sprayed both can increase yield by 11 93%,17 25% and 27 89%,respectively. |
