木酢多元叶面肥对水稻产量及抗病性的影响

Effects of apyroligneous fertilizer on yield and disease resistance of rice

水稻喷施木酢多元叶面肥的小区、田间及大面积示范研究表明 ,它能有效地提高水稻产量 ,分别比对照增产2 1% ,14 .2 0和 8%。大田每株实粒数增加 4 .5粒、瘪粒数降低 3.5个、千粒重增加 1.30 g。同时 ,使稻瘟病发病率降低了 11.70 % 。

The result of rice plot and large area experiment with a apyroligneous fertilizer showed that it increased the yield of rice efficiently,and the increase rates were 21%,14 20%,8% The number full grains increased by 4.5 per ear,1 000-grains weight increased 1.3 g,and the number of empety-grain decreased 3.5 per ear.At the same time,it decreased rice blast significantly the decrease rate was about 11.70%.
