针对常规栽培中存在的生育期长、易感染枯萎病等问题,开展了粉蕉两年两造高效栽培及其枯萎病防控技术研究。结果显示,综合技术处理区第1造产量和净收益分别比常规栽培对照区提高了59.59%和94.05%,枯萎病病株率下降93.01%;综合技术处理区第2造产量、净收益和枯萎病病株率分别为20437.20kg/ha、46817.88元/ha和6.25%。说明通过种植大龄组培苗、施足基肥、增施钾肥、无伤根追肥、预防地下病虫害伤根传病、提早留芽、反复割苗留茎等综合技术措施,可实现粉蕉两年两造高产高效栽培及有效防控枯萎病为害,但对具体的追肥量、留芽方式、宿根栽培收果期等指标仍有待进一步探讨。
Aiming at the problems of long growth period and susceptible to blight in conventional cultivation, this paper studied the two-year cultivation of powder plantain and its prevention and control of fusarium wilt. The results showed that the first-crop yield and the net yield in the comprehensive technology treatment area increased by 59.59% and 94.05% respectively compared with the conventional cultivation control area, and the rate of the blight-causing strain decreased by 93.01%. The second-crop yield, net income and wilt The diseased plant strains were 20437.20kg / ha, 46817.88 yuan / ha and 6.25% respectively. This shows that through the cultivation of large-scale tissue culture, Shizujifei, increasing the application of potassium fertilizer, no wound top dressing, prevention of underground pests and diseases root injury, early bud retention, repeated seedlings remain stems and other comprehensive technical measures, Producing high yield and efficient cultivation and effective prevention and control of wilt disease, but the specific amount of fertilizer, stay buds, perennial cultivation of fruit and other indicators remains to be further explored.
