Effects of meteorological factors in different ecoregions on yield-related traits of peanut production
摘要
Abstract
For well production layout and high-yield of peanut,meteorological effects were investigated.For exploring the correlation between cultivation habitat and peanut yield,9 peanuts(Arachis spp.)were planted in 7 dif-ferent ecological regions of Yunnan for 2 years.The effects of meteorological factors on peanut agronomic traits and yield were analyzed by ANOVA,correlation analysis and path analysis.Results showed that temperature and accu-mulated temperature,peanut number of fruiting,shelling percentage and yield from Dehong,Binchuan,Dongchuan,Lincang and Yanjin were higher,which could be desirable areas for planting peanuts.Variance analysis results showed that growth and yield were affected by genotype and environmental factors.Higher temperature and accumu-lated temperature were conducive to shortening the podding stage,and then shortening the whole growth period.The higher the temperature,the higher the aboveground part,the higher the number of fruits per plant and the number of full fruits,and at the same time increased 100-fruit weight and 100-kernel weight,thereby increased the yield.But the long light time and the large temperature difference between day and night were not conducive to the growth and shoot branching.关键词
