Effects of Sowing Date on Development,Dry Matter Accumulation and Yield of Shanghua 5
摘要
Abstract
The effects of 5 sowing dates on development,dry matter accumulation and yield of summer peanut variety Shanghua 5 were studied by random block design.The results showed that with the delay of sowing date,the growth period and emergence days were shortened,the underground dry matter accumulation decreased,the aboveground dry matter consumption increased at the later period,and the main traits of peanut gradually decreased.When the sowing date was on June 5,June 10 and June 15,the peanut yield was 6 027.81,5 558.36 and 5 027.80 kg/hm2 respectively,and all reached to a higher level with very significant difference.When the sowing date was on June 20 and June 25,the peanut yield was 3 994.46 and 3 838.91 kg/hm2 respectively,which still had some economic yield.Therefore,Shanghua 5 was a late sowing variety,and its optimum sowing date was from June 5 to June 15.关键词
