- 摘要:
- 在冀西北旱坡地采用窄土垄沟、宽土垄沟、窄膜垄沟、宽膜垄沟4种不同沟垄处理形式，以常规平作为对照，研究不同的沟垄形式对南瓜生长和产量的影响。结果表明：不同沟垄处理方式对南瓜的出苗、成苗影响较大，覆膜垄沟2个处理较平作出苗率分别提高6.0%和7.4%，成苗率提高9.0%和10.8%；沟垄处理幼苗生长亦较平作旺盛，鲜重、干重、株高分别提高26.6%～89.9%、19.5%～68.3%、12.5%～58.0%，侧根数增加9.2%～52.3%。各处理组产量均高于对照，较对照增产4.23%～32.39%，增加经济效益176.2～1 210.4元/hm2，尤以宽膜垄沟产量增产效果最为显著。综合出苗、幼苗的生长发育及产量因素，宽膜垄沟>窄膜垄沟>宽土垄沟>窄土垄沟>常规平作。
- Abstract:
- Four ridge planting patterns including narrow earth ridge(NER),wide earth ridge(WER),narrow film covering ridge(NFR) and wide film covering ridge(WFR) were adopted，in the meantime conventional flat land planting as control(CK) to study their effects on growth and yield of pumpkin in northwest Hebei province sloping dryland.The results showed that the two film cowering ridge planting patterns could influence pumpkin emergence and sprout greatly，of which emergence rate raised 6.0% and 7.4%,respectively,as well as sprout rate increased by 9.0% and 10.8%,respectively.The growth of pumpkin seedlings under different ridges planting patterns were more vigorous than CK.The fresh weight,dry weight,height,lateral root numbers of pumpkin seedling had greatly raised for all of treatment groups，including fresh weight increased by 26.6 to 89.9%，dry weight increased by 19.5% to 68.3%，plant height raised 12.5% to 58.0%，lateral root number increased by 9.2% to 52.3%.The yield for all treatment groups had improved than CK，with yield increasing by 4.23% to 32.39% and economic benefits increasing by 176.2 to 1 210.4 yuan/hm2,especially，film covering wide ridge(WFR) planting was the most significant of all treatments.Considering the effect of the emergence，the growth of seedlings and the yield，different treatment groups had consistent results：wide film covering ridge (WFR)> narrow film covering ridge(NFR)>wide earth ridge(WER)>earth narrow ridge(NER)>flat land planting(CK).
