冬闲地套种蔬菜及蔬菜废弃物还田对苎麻的影响

Effects of Ramie / Vegetable Intercropping and Vegetable Wastes Returning to Field on Ramie

对榨菜、莴苣和豌豆与苎麻套种后,不同套种模式及蔬菜废弃物还田对苎麻的主要农艺性状、纤维产量和品质的影响进行了研究。结果表明,套种蔬菜可以显著提高苎麻的纤维产量,但蔬菜废弃物还田对苎麻生长有影响,对苎麻的农艺性状和产量有降低作用。不同蔬菜套种对苎麻影响不同,产量表现为苎麻/豌豆>苎麻/莴苣>苎麻/榨菜。套种对不同季别的苎麻影响也不同,对头麻影响最大,二麻次之,三麻影响最小。套种和蔬菜废弃物还田对苎麻纤维断裂强力和纤维支数的影响较小。

The effects of different ramie/vegetable intercropping modes, Ramie/Tsatsai, Ramie/Lactuca sativa and Ram-ie/Pisum sativum, and vegetable wastes returning to field on the fiber yield, quality and agronomic traits of ramie were studied. The results showed that intercropping could increase the fiber yield significantly, while vegetable wastes returning to field had a negative effect on the growth of ramie and reduced the agronomic traits of ramie and fiber yield. Different vegetables had different effects on ramie, and the fiber yield showed the trend of Ramie/Pisum sativum mode〉 Ramie/Lactuca sativa mode 〉 Ramie/Tsatsai mode. Intercropping also had different effect on different season ramie crops, most on the first crop,while least on the third crop. Intercropping and vegetable wastes returning to field had no significant effect on fiber breaking strength and fiber fineness.
