摘要
为探讨水稻种植中沼液合适的施用方法,研究不同沼液运筹方法对水稻产量等方面的影响。结果表明:沼液不同运筹方法对水稻营养生长的影响并不显著,但增加追施沼液量易促使中小分蘖发育成长,使小穗所占比例提高,同时也易导致贪青迟熟,从而使千粒重、结实率、穗粒数等发生下降趋势,不利于产量提高,也对稻米品质产生不良影响。在水稻种植中应提高基肥沼液比例,控制追施沼液用量,基肥与穗肥以3∶1的比例较为适宜。
To explore the appropriate application method of biogas slurry on rice,the paper studies the effects of different fertilization application methods of biogas slurry on yield of rice.The results showed that the effects of different biogas slurry management on rice vegetative growth was not significant,but with the increasing of biogas slurry topdressing amount,the development of middle and small tillers was promoted and the proportion of small spikes increased,while plant maturity was unfavorably delayed.As the result,1 000-grains weight,seed setting rate and grains per panicle showed a downtrend,and has adverse effects on yield and quality of rice.Therefore,during rice growth period,basal fertilizer should be applied more and the amount of biogas slurry at topdressing should be controlled.Basal and panicle fertilizer with a ratio of 3∶1 is more appropriate.
