After the rain, due to soil compaction, lack of oxygen, and airtightness, the leafy vegetables are rotten and yellow leaves are dead, and the leaves are like boiling water. The radish tubers are difficult to inflate and rot are severe; the solanaceous vegetables are caused by no light, causing the fruit to fall into fruit and fruit, and the growth is hindered. Even the Chinese cabbage cultivated in the high ridge and small sorghum also has rooting phenomenon; the onion and garlic leeks appear Yellow leaf rotten leaves, downy mildew, gray mold disease occurs seriously; blue white cauliflower, flat cabbage, because of the large water, cracking phenomenon, but also led to a recent rise in vegetable prices!
