The role of trace element fertilizers

Trace elements refer to the growth of plants, but relatively small amounts of elements, mainly iron, copper, zinc, manganese, molybdenum, boron and so on. Although the content of trace elements in crops is small, they are often part of enzymes or coenzymes in plants and have strong specificity, which is indispensable and irreplaceable for crop growth and development. Therefore, when the crop lacks any trace elements, growth and development are inhibited, resulting in reduced yield and quality, serious or even unacceptable. On the other hand, if there are too many of these elements, poisoning will occur, affecting crop yield and quality, and causing some local diseases in humans and animals. The following is a brief introduction to the nutritional effects of six trace elements and the performance of crops in the absence of nutrients to increase the farmers' understanding of trace element fertilizers.
1. Nutritional effects of boron Boron is concentrated in the shoot tip, root tip, leaf and flower organs in plants. The content of dicotyledonous plants is often higher than that of monocotyledons. Boron can promote the crop and affect the normal development of the reproductive organs. An important symptom of boron deficiency is that it cannot develop normally or even form, which affects the harvest of crops. Boron promotes the synthesis and transportation of sugar in crops. In the absence of boron, chloroplasts degenerate, affecting photosynthesis. Boron can increase the nitrogen fixation activity of leguminous rhizobium and increase the nitrogen fixation. When boron is deficient, the roots remain underdeveloped and affect the nitrogen fixation. Boron also enhances crop stress resistance.
2. Nutrient action of molybdenum Molybdenum is a nitrogen-fixing microorganism, especially when rhizobium symbiotic with legumes fixes atmospheric nitrogen. At the same time, it can enhance the photosynthesis intensity of the leaves. In the absence of molybdenum, the plants are short, the leaves are chlorotic, the leaves are scorched, and they curl inward and become wilting.
3. Nutritional role of zinc Zinc can promote the photosynthesis of crops. It is a component of various enzymes. When zinc deficiency occurs, crop growth and development are stagnant.
4. Nutrient action of manganese The chloroplasts of plants contain fierce, manganese can promote seed germination and seedling growth, and the photosynthesis, respiration and nitrate accumulation in the body are affected by manganese deficiency. It is characterized by chlorotic chlorosis between leaves, with brown spots, and gradually spread over the whole leaves, making the leaves turn red-gray and the leaves shrink.
5, the nutritional role of iron Iron is indispensable for the formation of chlorophyll, it is difficult to transfer in the plant body, so the leaf "chlorosis" is the performance of plant iron deficiency, and this chlorosis is first manifested on young leaves. In addition, iron has an effect on photosynthesis and respiration of plants.
6, the nutritional role of copper participate in plant photosynthesis, respiration, nitrogen metabolism, enhance plant resistance. In the absence of copper, the plant grows thin, the new leaves are yellow, withered and dry, the tip of the leaf is curled white and has necrotic spots.
