In production, vegetable farmers often go into such a misunderstanding that the weaker the plants grow, the more they use fertilizer. Are the plants weaker and weaker? The answer is no, because there are many reasons for the weakness of the plant, and lack of fertilizer is only one aspect of it. If the vegetable grower does not analyze the reasons and blindly supplement the fertilizer, it will only cause the concentration of the fertilizer solution in the soil to become higher and higher. When the concentration of the soil solution exceeds 0.5%, the vegetables will burn roots, which will cause the trees to become weaker and weaker. Therefore, amaranth farmers must go out of the weaker sections of the tree and use more fertilizer. When it is found that the plants are too weak and they do not send trees, it is necessary to carefully analyze the reasons, and then symptomatic treatment is the best policy. So, in addition to the lack of fertilizer, what are the other reasons that cause the plants to grow weaker? Here we analyze: First, leaving too many fruits, weak trees caused by excessive load. In production, many vegetable farmers always want to keep fruit as much as possible. The result is often due to excess fruit, plant load is too large, resulting in weakened plant growth. In this case, proper supplementation is necessary, but it cannot solve the fundamental problem. Because the plant's ability to attract fertilizer is limited, it can't be absorbed without applying a lot of fertilizer. In other words, how much fertilizer is applied does not necessarily provide much fruit. Too much fertilizer will only cause waste or rooting. Obviously, in this case, it is sensible to reduce the burden of fruit thinning, in order to accelerate the vegetative growth of the plant, in order to achieve the purpose of turning from weak to strong. Second, excessive leaf sparing, weak photosynthetic nutrition supply caused by weak trees. When the leaf growers snoring, if the leaves are too sparse, the photosynthetic nutrition produced by the leaves will not satisfy the growth of the plants and fruits, and the plants will grow weaker. In this case, even if you make up for it, it does not help, because the plants do not have enough fat. Therefore, if we want to solve this problem, we should only provide reasonable photosynthetic nutrition to the plants. Third, the root system is injured, weak weak absorption capacity. When the roots of the plants are damaged by roots, roots, etc., the ability to absorb nutrients becomes weak and the trees become very weak. In this case, blindly compensating for fat can only be counterproductive. The correct solution should be timely healing of the root system. If the roots of lotus roots should be promptly drained and dehumidified, and the ground temperature should be raised; the earthworms should be plucked at a proper time; roots should be used, roots and roots, or bio-fertilizer should be used for irrigation. Burning root can reduce the concentration of fertilizer solution in the soil by appropriate irrigation, and use Iodian, Chitin, Genjia and other irrigation sources to promote its recovery as soon as possible.
