Abstract: A study was carried out on different amount of polypeptide product mixed with nutrition soil on rice yield and physiology characteristics. The results showed that the rice seedling quality of polypeptide product mixed with nutrition soil had no significant difference with two comparisons, but the yields of which increased. The treatment of the highest yield was 1.5 kg/667 m2, it increased rice yields 4.57% and 10.21% compared to drug control and blank control. The polypeptide product is safe for rice, it is recommended to use in rice production.

Key words: polypeptide product, nutrition soil, yield, rice

摘要： 对不同用量“多肽保”拌营养土对水稻生理特性和产量的影响进行了试验。结果表明，每667 m2使用“多肽保” 1.0 kg、1.5 kg、2.0 kg拌营养土，秧苗素质与对照相比差异不大，但均比对照增产；表现最好的是1.5 kg/667 m2“多肽保”拌营养土处理，产量比药剂对照增产4.57%、比空白对照增产10.21%，且对水稻生长安全，建议在生产上推广使用。
