不同种植模式对燕麦、麦蚜及天敌的影响
Effect of Different Cropping Patterns on Avena sativa,Wheat Aphids and Natural Enemies
摘要
Abstract
This study mainly adopts three planting patterns for oat cultivation(Avena sativa):intercropping,mixed cropping,and monocropping.The crops used for intercropping and mixed cropping are spring rapeseed,common vetch,and hairy vetch,oat monocropping is the control.This study investigates the effects of different cropping patterns on the growth periods,nutritional quality,fresh grass yield,grain yield,and the density of wheat aphid natural enemies,and compares their control effects against aphids.The following results are obtained:The three intercropping treatments have no significant effect on the growth periods of oat,while the three mixed cropping treatments delay the harvest period by 1-4 days.Mixed cropping with common vetch or hairy vetch in oat fields significantly increases the contents of crude protein(CP),acid detergent fiber(ADF),and neutral detergent fiber(NDF)in oat.None of the six treatments exerts a significant influence on oat grass and grain yield.During the oat booting stage,the aphid population density in oat fields mixed with spring rapeseed,common vetch,or hairy vetch is significantly lower than that in monocropped oat.The aphid population density in the three intercropping treatments shows no significant difference compared to the control.The natural enemy density is the highest in oat fields mixed with hairy vetch.The natural enemy densities in oat fields mixed with spring rapeseed or common vetch,as well as in rapeseed intercropped with oat,are all significantly higher than in the control.During the flowering stage,the aphid population densities of oat in all six treatments are lower than in the control,and the natural enemy density is the highest in oat intercropped with hairy vetch.During the filling stage,the wheat aphid population density of the three mixed cropping treatments is lower than that in the control,and these three patterns exhibit relatively high control effects against wheat aphids,reaching approximately 52.81%-62.23%.关键词
