摘要[目的]研究新型葉面肥YZS和GZS在水稻不同生育時期組合噴施對水稻產量的影響。[方法]設置2個處理，處理①是先在分蘗期噴施YZS 750 g/hm2，然后在孕穗期噴施GZS 750 g/hm2；處理②是在處理①基礎上，在水稻齊穗期再噴施GZS 750 g/hm2， 研究 不同處理對水稻產量的影響。[結果]水稻分蘗期噴施GZS 10 d后觀察發現，2個處理水稻株高分別為86.5和86.3 cm，而對照株高為88.3 cm，差異極顯著；根長分別為12.1和12.3 cm，對照為11.4 cm，差異顯著，且處理根系數量多于對照。收獲前2 d測產結果表明， 2個處理有效穗數和穗粒數與對照無顯著差異；2個處理結實率分別為82.72%和83.96%，對照僅為74.85%，差異顯著；2個處理千粒重分別為24.77和25.80 g，對照為24.13 g，差異顯著；2個處理理論產量分別為11 471.85、10 531.35 kg/hm2，對照僅為9 662.4 kg/hm2，差異顯著。[結論]YZS對水稻株高有抑制作用，但對根系生長有明顯的促進作用；2種處理均顯著提高水稻產量，齊穗期噴施GZS可明顯增加千粒重，增產效果更明顯。

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/hm2 first of spraying YZS at tillering stage and 750 g/hm2 of the GZS at booting stages.Treatment ② was based on the treatment ①，and the GZS was 750 g/hm2 in 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 000grain 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/hm2 and 10 531.35 kg/hm2 respectively， 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.

葉面肥作為一種靈活的根外營養產品，使用便利，起效迅速，已廣泛應用于包括水稻在內的各種作物上，取得了良好的效果。目前市場上葉面肥種類眾多，普遍存在肥效期短、功能單一、效果不穩定等問題。研發生產多功能、長持效的新型復合葉面肥成為商業性研發的熱點。養分平衡供應是農產品優質高產的關鍵[1]，該試驗的新型葉面肥，富含多種元素，力求養分均衡，且采用新型螯合劑IDHA（亞氨基二琥珀酸），以提高微量元素的吸收和利用。……
