Vegetables rely on leaves for photosynthesis, conservation of leaves is a prerequisite for high yields of vegetables. Therefore, in vegetable production, vegetable farmers have noticed the conservation of plant leaves. However, most vegetable farmers have devoted their energy to the maintenance of new leaves on the upper part of the plant, while most of the older leaves have not paid enough attention to it. Recently, when the reporter interviewed Xiqing Village of Tianliu Township, Shouguang City, the village farmer Zhu Society discussed his views on this issue. He said: “The aging of plants begins with the lower leaves, and the onset of disease is very easy to start from the lower old leaves. Therefore, vegetable leaves should start from the lower leaves."
Think about it carefully, Zhu learned a lot about it. In general, the leaves are aged from the bottom upwards, and the old leaves in the lower part of the plant are also the most susceptible to disease infestation. However, vegetable growers usually focus on the middle and upper leaves of the plants, whether they are spraying fertilizers, growth regulators, or spraying fungicidal insecticides. However, for the lower old leaves, very few people are careful to spray them. . This is obviously wrong because the leaves in the lower part of the plant are useful as long as they are left. They are no longer useful. Therefore, all the leaves on the plant should be maintained well, and should not be favored by others.
So, how can the leaves of the plant be cured? According to the Zhu Institute, the old leaves in the lower part of the vegetables are most likely to be lacking in nutrients, so they must be sprayed with foliar fertilizer in time. In production, he discovered that 0.5% potassium dihydrogen phosphate and nutrient-rich aromatic leaf foliar fertilizers were found. Spraying effect is very good. Can also be used to love more and 120 large clouds sprayed, but can not be used frequently, because hormones used more likely to cause premature failure of vegetables. Usually prevent disease can be used chlorothalonil, thiophanate-methyl and other broad-spectrum fungicides spray, pay attention to spray carefully, positive and negative sides should be sprayed. "I stress again the importance of the lower blade, not that the lower blade is more important than the upper one. The purpose is to cause everyone to pay attention to the lower blade, so you don't need to open a special spot on the lower blade when spraying. Don't listen to me. After the words, then shift the focus of raising the leaves to the lower leaves, and ignore the upper leaves, then my guilt can be big." Zhu learned to say wittyly.
