“天骄”液肥在水稻增产上的应用研究

Study on “Tianjiao” Liquid Fertilizer in Increasing Rice Vield

用不同浓度的“天骄”液肥作水稻浸种和孕穗期、灌浆期叶面喷雾。结果表明 :1∶80“天骄”液肥浸种可显著提高水稻秧苗素质 ,增加有效穗 ,增产 3 1 4 % ;喷雾处理的最佳浓度是 1∶30 0 ,最佳时期是孕穗期和灌浆期 。

Different concentration of “Tianjiao” amino acid liquid fertilizer are used to saturate rice seeds and spray rice foliage in period of filling and period of panicle development. The results are showed as follows: 1∶80“Tianjiao” liquid fertilizer is used to saturate rice seeds can increase notably seedling quality and number of effective panicle, it can increase rice yield 7 8% compared with the contrast. The best concentration of spray foliage is 1∶300, The best period of spray foliage is period of panicle development and period of filling, 1∶300 “Tianjiao” liquid fertilizer can increase notably the number of filled grains and the 1000 grains weight.
