加氧灌溉对超级稻农艺性状影响的研究
Study on Effect of Oxygen-adding Irrigation on Agronomic Traits of Super Rice
摘要
Abstract
The effect of different oxygen-adding irrigation treatments on the agronomic traits of super rice was studied through field experiment .The results showed that:as compared with the conventional control , both the treatment of mechanically adding oxy-gen and the treatment of chemically adding oxygen could promote the growth of super rice plants .Among different treatments , the treatment A4(conducting mechanical ventilation at 20:00 for 4 min, once a day) obtained most significantly promotive effects on the plant height and root fresh weight of rice seedlings;the treatment A6(conducting mechanical ventilation at 20:00 for 4 min, once ev-ery two days) had most obviously promotive effect on the elongation of root system of rice at various growth stages ;the treatments B1 and B2(adding 10~20 mL 0.03%hydrogen peroxide every time, once every 15 days) was the most advantageous to the increase in root-shoot ratio of rice at later growth stage .关键词
