威优481是一个优质杂交稻品种,增产优势已为人们公认,但其生长发育规律研究甚少。为揭示威优组合在不同时期对不同养分的需求,达到生产上施肥合理,以提高作物产量,促进品质的改良,我们连续两年在院农场进行了威优481杂交稻需肥规律的研究。一、试验设计本项研究采用田间试验,设3个处理4次
Weiyou 481 is a high-quality hybrid rice variety, which has been recognized as an advantage of increasing yield, but little is known about its growth and development. In order to reveal the demand of different nutrients from Weiyou combination in different periods, and to achieve reasonable fertilization in production to improve crop yield and improve quality, we conducted the study on the rule of fertilizer requirement of Weiyou 481 hybrid rice for two consecutive years in hospital farms. First, the experimental design This study used field trials, set 3 to deal with 4 times
