绿豇豆若干高效配套技术的研究

Preliminary Study on Some High Effective Techniques Applied in Green Asparagus Bean

根据绿豇豆生长习性和高效配套技术试验结果表明,在整枝方式上宜采用抹芽、摘心;采用质量分数为 2.5%敌杀死乳油 2500倍液和覆盖 25目防虫网纱防治豇豆荚螟,安全,有效; 667 m2施基肥 4 000 kg腐熟厩肥+25 kg复合肥,种子产量增加显著;将 200 kg种子用质量分数为 56%磷化铝 3.3 g在密闭容器中熏3 d,后晾种 4 d,防治绿豆象既省工、防效又好且种子发芽率高.1999～2001 年间对 5 种配套技术上进行试验研究,筛选出各自的高效配套技术.

Top-picking and bud picking are favorable to Green Asparagus Bean based on it’s living habit and our experimental research. In addition, it was both effective and safe when using a dilution (2500 times) of 2.5% Dishasi (commercial name) emulsion to spray and employing a 25-hole-net to cover green asparagus bean against Maruca testulalis Geyer. The yield of seeds will be remarkable high if using 4000 kg decayed manure and 25 kg compound manure per 667m2. The rate of seed germination was high and bruchidius was well controlled when seeds were treated by 3.3g of 56% aluminium phosphide(AP) in an airtight container following air-dried for 4 days.
