黄瓜植株生长弱时,很容易感染细菌性斑点病,继而导致灰霉病和霜霉病的大发生,造成黄瓜严重减产。对于这三种病害,以往都用化学农药进行防治,但效果都不理想,甚至会发生中毒现象。为了解决这些问题,近年来,从黄瓜植株营养角度出发,研制出一种红糖发酵液,不仅能防治这三种病害,而且还能刺激黄瓜植株生长,延长黄瓜采收期,提高黄瓜的产量和品质。 红糖发酵液的制作:先将红糖3千克溶于5千 Cucumber plant growth is weak, it is easy to infect bacterial speckle disease, which in turn led to the occurrence of gray mold and downy mildew, resulting in serious cucumber yield. For these three kinds of diseases, chemical pesticides were used for prevention and treatment in the past, but the effects were not satisfactory and poisoning could even occur. In order to solve these problems, in recent years, from the perspective of cucumber plant nutrition, a brown sugar fermentation broth was developed to not only prevent these three diseases, but also stimulate the growth of cucumber plants, prolong the harvest period of cucumber and increase the yield of cucumber quality. Preparation of brown sugar fermentation broth: first dissolved 3 kg of brown sugar 5 thousand
