蔗农乐微生态菌制剂在甘蔗上的应用初报

Application of micro-ecological bacterial agent Zhenongle on sugarcane

以新台糖22号为试材,探讨蔗农乐微生态菌制剂在甘蔗上的施用效果。结果表明:在生态菌制剂处理中,以菌液浸种(A)和浇种(B)两个处理的效果较好,其公顷产蔗量分别为133.34、129.74t,比CK(常规方法播种)增产17.49、13.89t/ha,增幅为15.1%、12.0%;扣除菌剂费及人工费投入,浸种处理每公顷可增收3940.0元,浇种处理每公顷增收2807.0元,分别比对照增长12.4%和8.8%。菌液浇根(C)处理每公顷产蔗量119.18t,比CK增产3.33t/ha,增幅为2.9%;扣除菌剂费和人工费投入,浇根处理的效益出现负值,略低于CK。可见,蔗农乐微生态菌制剂的施用方法以浸种和浇种为好。

An experiment has been conducted to study the effects of micro-ecological bacterial agent ＂Zhenongle＂ on sugarcane variety ROC 22. The bacterial solution was applied on seed canes and seedling according to following treatments： （A） soaking seed canes（16.0t/ha） in bacterial solution for 30-60 min, （B） spraying bacterial solution on seed canes（19.5 t/ha） during plantation in field and （C） spraying bacterial solution on seedling roots （19.5 t/ha）. In control treatment only water was used. As compared to the control, the treatments A and B showed better effects on some traits of sugarcane. The yield of sugarcane was found to be 133.34 and 129.74 t/ha with an increase of 17.49（15.1%） and 13.89 t/ ha （12.0%）, and the net increase in income was 3940 and 2807 yuan RMB/ha with an increase of 12.4% and 8.8%, on application of treatment A and B, respectively. Treatment C resulted in cane yield of 119.18t/ha with an increase of 3.33t/ ha （2.9%）, but the net income was lower compared to control. Therefore soaking the seed canes and spraying ＂Zhenongle＂ solution on seed canes during plantation in field might be recommended to improve the yield of sugarcane.
