Symptoms of manganese deficiency and iron deficiency are basically similar. There are chlorotic spots between the veins and gradually form stripes, but the veins are still green. Deficiency of boron leaves chlorosis, leaf hypertrophy shrinkage, curling up the edge of the leaves, roots are not developed, the top buds and radicles growth point of death, falling flowers and falling fruit. Calcium-deficient end buds are damaged and cause apical necrosis. The young leaves are chlorotic. The leaf margins are curled and coked. The tips of the leaves are usually hooked. The sulfur-deficient leaf color turns light green, and even becomes white. It spreads to new leaves, the leaves are small, the plants are short, the flowering is postponed, and the roots are obviously elongated. Zinc-deficient plants show marked atrophy and ossification between leaves, yellowing or decreasing leaves, yellow spots between veins, spread to new leaves, young leaves hard and small, and yellow and white. The lack of molybdenum young leaves yellow-green, leaf loss of green withered, resulting in necrosis. Copper leaves have white tips, young leaves are atrophic, and white leaf spots appear. The factors causing the deficiency of the factors are various, such as insufficient nutrition or disorders; the soil is too acidic and over-alkaline; the soil loses certain nutrient elements; the physical and chemical properties of the soil are poor, etc., and various kinds of deficiency syndromes are formed. . Control methods, to the right medicine, take the following measures: 1 outside dressing, according to the performance of symptoms, infer what elements are lacking, that is selected to prepare a certain concentration of the solution, spraying the foliage. 2 Increase the use of organic fertilizer, improve soil physical and chemical properties. 3 Use all-element compound fertilizer. 4 Implement winter plowing and drying soil, promote soil weathering, and exert the potential fertility of the soil.
