Although trace elements play an important role in the growth of plants, if more fertilizer is applied, it will also be detrimental to plant growth. Therefore, the micro fertilizer cannot be surplus, so what will happen if the micro fertilizer is used excessively in crops? Details are as follows:
1. Zinc excess Zinc excess will make the young leaves of the plant appear green and yellow, and the stem, petiole, and epidermis of the leaf appear reddish brown. Excess zinc in rice, weak seedling growth, and yellow leaves; excess zinc in wheat, brown spots appear on the tip of the leaves; excessive zinc in soybean, leaves appear purple especially at the base of the middle ribs, and leaves shrink.
2. Chlorine excess disease When chlorine is excessive, crops are prone to burn roots and dead seedlings. If it is applied to crops that avoid chlorine, such as sweet potatoes, tobacco, and fruit trees, it will cause the product quality to decline.
3. Copper excess. Copper excess will cause the leaves of the crop to turn yellow, the root elongation will be hindered, the coil will not spread, or the formation of divergent roots and claw roots. Rice copper poisoning, yellowing of rice seedlings, growth stagnation; excessive copper in wheat, the plant will become deeper, rigid, the lower leaves yellow, the roots curl. Due to the excess copper, it will obviously inhibit the absorption of iron. Therefore, sometimes the crop excess copper will also appear as iron deficiency.
4. Manganese excess disease is quite different due to different crops, but most of them show root browning, brown spots appear on the leaves, and there are yellowing or purple-red on the edge of the leaves, and tender leaves are rolled up. Excess manganese in apples can easily cause rough skin disease, excess manganese in rice, yellowing of leaves, high-noise tillering, and brown pollutants in the stem base. Excess manganese will also inhibit the absorption of molybdenum. Molybdenum deficiency in crops on acid soils may be caused by excess manganese.
5. Boron excess boron moves with the transpiration flow in the plant body, and the boron remains with the loss of transpiration. The blade tip and edge of the boron are easily surplus, so the excess of boron is mainly manifested in the periphery of the blade, mostly yellow or brown border, the blade yellow It becomes brown and scorched in severe cases, and there are so-called "Phnom Penh" on vegetable crops. Excess boron in rice, browning of leaf tips, dry roll; excess boron in barley, leaves will have a lot of brown spots scattered.
