1, leaf yellowing: at this time the plant can not normal synthesis of chlorophyll and growth factor, to maintain the green leaves, the leaves will become yellow. 2, plant short: plants lack of zinc when the growth rate will become slow, and ultimately the phenomenon of stopping the growth of the 3, remedies: want to let the plant to resume growth, it is necessary to make up for the application of zinc-containing fertilizers.

1, yellow leaves

After the zinc deficiency of plants, there will be yellow leaves, because at this time the plant can not normally synthesize chlorophyll, to maintain the green leaves, the leaves will appear on the yellow spot, and gradually expand, and ultimately lead to the yellowing of the leaves all the way to fall.

2, short plants

After the plant lacks zinc, the phenomenon of short growth will occur. After the lack of zinc in plants, not only can not synthesize chlorophyll, but also lead to a reduction in the content of growth hormone, thus slowing the phenomenon of growth, over time, will stop growing, resulting in a short plant, lower yield.

3, the solution

In order to solve the problem of zinc deficiency in plants, you can use zinc sulfate as a base fertilizer, applying fifty pounds of sulfuric acid per acre of land, so that the plant grows healthily, and in the sowing of seeds before the seeds to be mixed with zinc sulfate and water, seed mixing treatment, to supplement the zinc element.
