保护地黄瓜生产中覆膜对滴灌措施应用效果的影响

Influence of Film Mulching on Application Effect of Drip Irrigation Measures in Cucumber Production in Protected Field

[目的]探讨保护地黄瓜生产中滴灌和膜下滴灌措施的应用效果。[方法]选用"龙园绿春"旱黄瓜为供试品种,研究滴灌和膜下滴灌处理对黄瓜植株茎粗、株高、地上部分和地下根系生物量以及对黄瓜产量的影响。[结果]与滴灌处理相比,膜下滴灌处理明显增加了植株茎粗,除了定植期外,其他各个时期膜下滴灌处理的茎粗均显著高于滴灌处理(P<0.05);滴灌和膜下滴灌处理植株株高之间的差异并不显著(P>0.05)。覆膜对滴灌措施下的黄瓜地上植株和地下根系的生物量积累产生明显的促进作用,并且促进了黄瓜产量的提高。[结论]该研究为东北地区保护地发展节水滴灌技术提供了实践参考。

[Objective] The aim was to discuss the application effect of drip irrigation and drip irrigation under mulch in cucumber production in protected field. [Method] With dry land Longyuanlvchun cucumber as tested variety, the influence of the treatments of drip irrigation and drip irrigation under mulch on stem diameter, height, above-ground and under-ground root biomass of cucumber plants and cucumber yield were studied.[Result] Compared with drip irrigation treatment, the plant stem diameter was obvious increased by the treatment of drip irrigation under mulch. Except establishment stage, the stem diameter by the treatment of drip irrigation under mulch in each other stages was sig- nificantly higher than that by drip irrigation treatment （ P 〈 0.05 ）. The difference among height of plant treated by drip irrigation and drip irrigation under mulch was not significant （P 〉 0.05 ）. The film mulching had obvious promotion on above-ground and under-ground root biomass accumulation of cucumber under drip irrigation and promote the increment of cucumber yield. [ Conclusion ] The research provided the practical reference for developing drip irrigation technology of water saving in protected field of northeast area.
