据试验，给农作物喷施米醋，方法简单，无毒害，成本低，对多种农作物具有明显的增产效果。在小麦孕穗期，用３００倍液米醋稀释液喷施，增产１２．３％～１５．６％；水稻分蘖期，喷施３００倍米醋稀释液、孕穗期喷施１００倍液的米醋，增产１８％；玉米生长期，喷施３００倍? According to the test, spraying vinegar to crops is simple, non-toxic, low in cost and has obvious yield increase effect on many kinds of crops. At the booting stage of wheat, the rice was sprayed with a 300-fold dilution of rice vinegar to increase the yield by 12.3% -15.6%. During the tillering stage of rice, rice vinegar was sprayed with 300 times of diluted vinegar and 100 times of rice vinegar at the booting stage, yielding 18 %; Corn growth period, spraying 300 times?
