Effects of Sowing Date on Growth and Yield of Direct-seeding Rice in Chengdu Plain
摘要
Abstract
The effects of sowing date on growth and yield of direct-seeding rice was researched through pot experiment by using three-line hybrid rice Dexiang 4013 and Chuanzuo 6 you 177 in Chengdu plain. The results indicated that along with the delayed sowing date, the whole growth period was shortened, the number of leaves on main stem reduced, leaf emergence speed was accelerated. Under the condition of the same basic seedling number, along with the delayed sowing date, the maximum tiller number per plant, the earbering tiller percentage and the yield were decreased.关键词
