不同间种绿豆方式对甘蔗产量和品质的影响研究

Effect on Yield and Quality of Sugarcane Intercropped with Mung Bean

以甘蔗品种新台糖22号（ROC22）和绿豆品种郑绿8号、品绿04108为试验材料,设计不同甘蔗行距和绿豆间种方式,研究甘蔗间种绿豆对甘蔗生长、产量及品质的影响.结果表明,甘蔗间种绿豆,甘蔗前期生长相对较慢,但不影响甘蔗的分蘖和成茎;绿豆压青可以促进甘蔗伸长前期的蔗茎伸长;甘蔗合理间种绿豆,可以促进甘蔗增产3.30％ ～ 7.66％;绿豆压青对提高甘蔗品质有一定促进作用,蔗汁重力纯度比对照提高0.80％ ～ 2.54％;甘蔗间种绿豆可以收获绿豆约434.85 ～470.55 kg/hm2,产值增加约4500元/hm2;综合效益最好的是甘蔗行距1.2m间种1行绿豆、收豆后进行压青处理方式.

The sugarcane variety ROC22 and mung bean variety ZhengLü8 and PinLü04108 were chosen for the experiment.Different row spacing of sugarcane planting and different intercropping manner of mung bean were designed to study their effects on growth,yield and quality of sugarcane.The results showed that intercropping mung bean,sugarcane growth rate was relatively low at the early growth stage,but tillering and stem forming were not affected.The stem elongation rate could be promoted by green manure dresing with mung bean.The sugarcane yield increased by 3.30％-7.66％ under rational mung bean intercropping manner.The sugarcane quality,to some degree,could be improved by green manure dressing.The sugarcane juice gravity purity was 0.80％-2.54％ higher than the control.434.85-470.55 kg per hectare mung bean could be harvested and gained an additional income of 4,500 RMB yuan when planting sugarcane intercropped with mung bean.Planting sugarcane with 1.2 meter row spacing and intercropped with mung bean alternately and after harvesting adopting green manure dressing immediately could get the best comprehensive benefits.
