摘要
2003年单季水稻发生高温热害。在N、P2O5、K2O施用量试验中的N80P120K160处理和开花期喷施NaB4O7.10H2O和KH2PO4混合溶液处理,表现出极显著抗高温热害能力,结实率和千粒重大幅度提高,减轻了灾害损失。为以后水稻遇高温热害提供了施肥抗灾的参考依据。
The single cropping of rice suffer hot disaster of high temperature in 2003.In applicated quantity of N, P2O5 and K2O fertilizers experement, dealt with N80P12O K160 (kg/hm^2) or in florescence sprayed solution mingled by NAB4O7·H2O and KH2PO4 it showed most notable capability against hot disaster and increace by a large range on fructification rate. The damage was reduced. This provides an reference basis for fertilization to rice against hot disdaster when it meets high temperature later.
