Abstract
[Objective]The effects of combined foliar fertilization of YZS and GZS on rice yield in different growth stages were studied by field experiment.[Method]Treatment ① was 750 g/hm2first of spraying YZS at tillering stage and 750 g/hm2of the GZS at booting stages.Treatment② was based on the treatment①,and the GZS was 750 g/hm2in the full heading stage.[Result]Ten days later after the rice tillering stage,the rice plant height were 86.5 and 86.3 cm respectively,while the contrast area was 88.3 cm, and the difference was significant.The root length was 12.1 and 12.3 cm respectively,the control area was 11.4 cm,the difference was significant,and the number of root systems in the treatment area was more than that of the control area.The results showed that there was no significant difference between the effective panicle number and the number of grains per spike in the two treatments.The seed setting rate was 82.72%and 83.96%respectively,and the control area was only 74.85 %,the difference was significant.The 1 000-grain weight of two treatments areas were 24.77 and 25.80 g respectively,and 24.13 g in the control area,which was significantly different.The theoretical yield of the two treatments were 11 471.85 kg/hm2and 10 531.35 kg/hm2respec-tively,and the control area was only 9 662.4 kg/hm2.The difference was very significant.[Conclusion]YZS had an inhibitory effect on the plant height, but had a significant effect on root growth.Both of the combined treatments significantly increased the yield of rice,and the effect of the spraying of the GZS in the full heading stage was significantly increased.关键词
