根际秸秆生物反应堆技术在马铃薯上的应用

Application Effect of Rhizosphere Straw Bioreactor Landfill Technology on Potato

[目的]探讨根际秸秆生物反应堆技术在马铃薯上的应用效果。[方法]以薯引1号为供试材料,以不放反应堆为对照,研究根际秸秆生物反应堆技术对马铃薯物候期、田间性状及产量的影响。[结果]处理较对照出苗期提前2 d,现蕾期提前4 d,成熟期较对照提前4 d,且处理小区幼苗发育健壮,其晚疫病的发病率明显低于对照。处理小区茎杆粗壮,薯块膨大时间早,且单株薯块数增多,平均单株薯块数增加0.63个,且薯块整齐,薯皮鲜艳,大、中薯率高,平均增产12 159.7 kg/hm2,增产率40.43%。[结论]运用秸秆生物反应堆技术生产的薯块表皮光滑,色泽鲜艳,外观品质和综合质量明显提高。

[ Objective ] The aim was to discuss the application effect of rhizosphere straw bioreactor landfill technology on potato. [ Method] With Shuyin 1 as tested material and without reactor as control, the effect of rhizosphere straw hioreactor landfill technology on the phenophase, field characters and yield of potato were studied. [ Result ] Compared with control, the emergence stage of treatment advanced 2 d, squaring period advanced 4 d, mature stage advanced 4 d and the development of seedlings in the treatment area were robust. The incidence of late blight disease of the treatment was obvious lower than that of the control. The stem in the treatment area was strong, the enlargement time of potato tuber was early, the potato tuber number of individual plant was increased and the average potato tuber humor of individual plant was increased 0.63. rlhe potato tuber was trim, potato hull was brilliant, big and medium potato rate was high, the average increasing yield was 12 159.7 kg/hm^2 and increasing rate of yield was 40.43%. [ Conclusion] he coat of potato tuber produced by straw bioreactor landfill technology was smooth, the color was brilliant, its appearance quality and comprehensive quality were obvious increased.
