摘要:

【目的】 研究播期对棉花苗蚜种群动态和棉花产量的影响。【方法】 于我国冀南棉区研究4月16日、4月26日和5月6日三个播期对棉花出苗、苗期蚜虫种群动态及棉花产量相关参数的影响。【结果】 随着播期的推迟,棉花出苗率呈增高趋势,4月26日和5月6日播种处理的棉花出苗率显著高于4月16日。4月16日和4月26日播种处理的棉田苗蚜均出现了明显的发生高峰和蚜量快速下降过程,而5月6日播种的处理,苗蚜始终未出现明显高峰。随着播期的推迟,棉花单行产量也从3.94 kg(4月16日)增至5.46 kg(5月6日),表现出明显增产。【结论】 适当推迟播期能起到保苗、减轻早期蚜害和保证产量的效果。

Abstract:

【Objective】 The population of cotton aphid migrating from overwintering host to cotton field and the environmental conditions in the Yellow River Basin are important factors for the damage caused by this aphid. The paper aims to clarify the effect of sowing date on the aphid population dynamics and cotton yield.【Methods】 Effects of the sowing date April 16, April 26 and May 6 on the aphid population dynamics and cotton yield parameters were studied in cotton field of southern Hebei Province. 【Results】 The results showed that the cotton emergence rate increased with the delay of sowing period, and the cotton emergence rates on April 26 and May 6 were significantly higher than that on April 16. There was an obvious peak of cotton aphids in spring occurrence and a rapid decrease of aphid quantity in the treatments of April 16 and April 26, while there was no obvious peak of Aphids in spring in the treatments of May 6. In terms of yield, cotton yield increased significantly from 3.94 kg (April 16) to 5.46 kg (May 6) with the delay of sowing period. 【Conclusion】 Postponing the sowing dates of cotton can play the role of protecting seedling, reducing early aphid damage and ensuring yield.
