它还能促进光合作用，因为扩散到叶绿体中的碳酸需要以锌作活化剂的碳酸纤酶

It can also promote photosynthesis, because carbonic acid diffused into the chloroplast requires carbonic acid cellulase that uses zinc as an activator to promote the decomposition of carbon dioxide to participate in photosynthesis. The chlorophyll content decreases when zinc is deficient, causing albinism in the leaves. <br>There are 1707 soil samples in the study area. The effective zinc content ranges from 0.22 to 14.33 mg/kg, the average content is 2.67 mg/kg, the standard deviation is 1.44 mg/kg, and the coefficient of variation is 60%. High level

It also promotes photosynthesis, because carbonic acid enzymes that spread to chloroplasts require zinc as an activator to promote the breakdown of carbon dioxide to participate in photosynthesis, and the amount of chlorophyll in zinc deficiency decreases, resulting in albinoism in the leaves.<br>There were 1707 soil samples in the study area samples, with effective zinc content ranging from 0.22 to 14.33mg/kg, average content of 2.67mg/kg, standard deviation of 1.44mg/kg, 60% variation coefficient, class 2 standard, higher level

It can also promote photosynthesis, because carbonic acid diffused into chloroplast needs to be promoted by carbonic acid cellulase with zinc as activator to decompose carbon dioxide to participate in photosynthesis. When zinc deficiency occurs, chlorophyll content decreases, resulting in leaf albinism.<br>There are 1707 soil samples in the study area, the available zinc content ranges from 0.22 to 14.33 mg / kg, the average content is 2.67 mg / kg, the standard deviation is 1.44 mg / kg, and the coefficient of variation is 60%, which belongs to the second level standard and higher level<br>
