不同种植密度和栽培管理对辣木农艺性状的影响

Effects of Planting Density and Cultivation Technology on Agronomic Characters of Moringa oleifera in Dry-hot Valley of Yuanmou

研究了元谋干热河谷果用辣木在不同种植密度、不同管理条件对其物候期、农艺性状的影响。结果表明,辣木株行距2.5m×2.5 m与2 m×2 m在物候方面相差小,但在辣木生长量、果实性状和结果性状方面有差异。不同施肥和灌溉管理条件下在物候、辣木生长量、果实性状和结果性状方面有差异。辣木株行距2.5 m×2.5 m和不同管理条件下促进辣木生长、增强辣木开花结果的功能,有利于提高辣木果实产量。研究结果表明,适当增加株行距,加强辣木幼苗管理等技术措施可提高辣木种子产量。

The phenological phase and agronomic traits were studied by the experience of planting density and cultivation techniques of Moringa oleifera in the dryand hot valley of Yuanmou.The results showed that the effect of different planting density （2.5 m × 2.5 m and 2 m ×2 m） on the phenological phase was not obvious,but the increment and the characters of fruits were affected by different planting density.There were difference about the phenological phase,the increment and the characters of fruits at the fertilizing and irrigation conditions.On the 2.5 m ×2.5 m planting density and management conditions,the growth and fertility of M.oleifera could be improved and the yield of fruit could be increased.The results indicated that the fruit production could be increased through decreasing the planting density and enhancing management moderately.
