3个时期干旱对夏花生株型、农艺性状及荚果产量的影响
Effects of Drought in 3 Different Periods on Plant Type, Agronomic Characters and Pod Yield of Summer Peanut
摘要
Abstract
Through randomized block design and multi -point sampling methods, four treatments, drought in seedling stage,in late seedling to full flowering period,in flowering period and normal drip irriga-tion,were set up by artificial water control to study the relationship between the peanut plant development and yield traits with drought in 3 periods.It showed that drought in late seedling to full flowering period reduced the height of main stem and lateral branch length,which caused the plant type index was 1.02 at the 50th day after seedling.Under this treatment,flowering concentrated on 10~20 days after the initial flowering,the ef-fective needle rate was over 46%, the total branch number, single plant fruit number and single plant fruit weight were maintained in appropriate level, and the pod yield was not significantly different compared with normal drip irrigation.It also showed that drought in seedling stage promoted the total branch number, while drought in flowering period reduced the single plant fruit number and single plant fruit weight.Thus,drought in late seedling to full flowering period was the best treatment,which would help summer peanut create erect plant type and more suitable for machine harvest,and not decrease pod yield.关键词
