使君子规模化栽培关键技术研究

The Key Technology on Large-scale Cultivation of Quisqualis indica

为了优化使君子的栽培技术,研究了不同生长调节剂和扦插株行距对插穗成活率的影响以及大田栽植株行距对使君子果实产量的影响。结果表明,使用50mg/L的IBA(或NAA)浸泡12h后扦插或用500mg/L的IBA(或NAA)沾蘸后立即扦插,有利于提高扦插苗的成活率,插穗成活率为91%～94%,并促进提早生根;扦插株行距以10cm×10cm时成活率较高,同时苗床利用率高;茎扦插的根系比较发达,且成本相对比根扦插低。大田栽植时以200cm×200cm株行距为宜。

In order to develop large-scale filed cultivation of Quisqualis indica and enhance its application value,the key technologies,such as the effect of different growth regulator treatment on cutting survival rate in large-scale cultivation of Quisqualis indica,the effect of cutting density on the survival rate and cutting slips growth,and the effect of growing filed cultivation density on fruit yield of Quisqualis indica,have been studied.The results show that soaking in 50 mg/L IBA（NAA） for 12 h or cutting immediately after dipping 500 mg/L IBA（NAA） could improve the survival rate of the cuttings,and promote early rooting;the survival rate was 91%-94% with high utilization of seedbed when the cuttings density was 10 cm×10 cm.Also,the root of stem cutting was grew well with a lower cost,which makes it easy for large-area breeding.The plant line space was better to be 200 cm×200 cm.
