截杆处理对辣木树生长和产量的影响

Effect of Rod Cutting on the Growth and Yield of Moringa oleirero

以3年生缅甸野生辣木种为试验对象,在云南德宏进行比较试验,研究不同截杆处理对辣木生长和产量的影响。结果表明:辣木全年采收鲜叶4～6次,其中高产出现在6—7月份,产量占到全年的三分之一以上,因此,为了提高辣木产量,需要在4—5月做好辣木水肥管理和病虫害防治工作;截杆高度40和60 cm处理的辣木产量、分枝茎粗显著高于其他处理(P <0.05),综合考虑辣木树截杆高度为60 cm为宜。

A comparative experiment was conducted in Dehong,Yunnan Province to study the effects of different rod cutting treatments on the growth and yield of three-year-old wild Moringa oleirero in Myanmar.The results showed that fresh leaves were harvested 4 to 6 times a year,and the high yield now accounted for more than one third of the total yield in June to July.Therefore,in order to improve the yield of Moringa oleirero,it is necessary to do a good job in water and fertilizer management and pest control in April to May.The yield and branch stem diameter of 40 cm and 60 cm rod cutting treatments were significantly higher than those of other treatments(P<0.05).It was better to consider the rod cutting height of 60 cm comprehensively.
