Zinc sulfate contains sulfur and zinc elements, which can provide nutrients needed for crop growth, enhance the vitality of crop roots, promote the growth of crop stems and leaves, improve the fruiting rate and fruit quality; it can also prevent and control corn white seedlings and defects. The grains are bald, the rice seedlings are stiff and the ears are uneven.
Effects of agricultural zinc sulfate
1. Zinc sulfate contains sulfur and zinc, which can provide nutrients during the growth of crops.
2. Zinc is a component of various enzymes and can promote the formation of chlorophyll, protein, and ribonucleic acid in crops; sulfur is a necessary raw material for crops to synthesize nutrients such as amino acids, proteins, and cellulose.
3. Zinc can promote the formation of auxin in crops, enhance the vitality of crop roots, promote the growth of crop stems and leaves, and improve the fruiting rate.
4. Zinc can promote the fixation of carbon dioxide during photosynthesis and facilitate the utilization of nitrogen and phosphorus by crops.
5. After using zinc sulfate, it can also effectively prevent and control white seedlings, missing kernels, and baldness of corn; stiff seedlings, uneven heading, and low seed setting rate of rice; yellowing and uneven ears of wheat; and small leaf diseases and cluster leaf diseases of fruit trees.
6. Applying zinc sulfate can increase yield, activate seedlings and inhibit viral diseases.
What are the specific symptoms of zinc deficiency in common crops?
1. Wheat is deficient in zinc: the stalk nodes become shorter, necrotic spots appear on the top growth points, the leaf veins wilt and turn yellow or there are strong white and green stripes on both sides of the veins, the heading and flowering period are delayed or even impossible, and the wheat ears become significantly smaller and The kernels become lighter.
2. Zinc deficiency in rice: stiff seedlings, yellow seedlings, shrunken seedlings, red seedlings or burned seedlings are prone to occur. The plants become short and uneven in height, with fewer or no tillers, and the tips of the leaves curl inward. The surrounding area turns orange, brown spots appear on the leaves in the middle and late stages, the leaf tips turn red, or the flowers are not solid, and the maturity period is delayed.
3. Zinc deficiency in corn: the plants are short, the stalk internodes are shortened, the leaf veins are chlorotic and turn yellowish white, with albino stripes, white seedling disease occurs in the early stage, striped mosaic disease occurs in the middle and late stages (after jointing), and fruit ear baldness occurs in the later stage. sharp phenomenon.
4. Zinc deficiency in rapeseed: the leaves turn yellow and white, the leaves curl upward, the leaf tips droop, and the rapeseed root system becomes thin and small.
5. Zinc deficiency in fruit trees: branch internodes become shorter, axillary buds are clustered, branches become thinner, and leaflets are clustered. When zinc deficiency is severe, new branches will die from top to bottom, leaves will fall early, fruits will become smaller, and the peel will become thicker. , the taste becomes worse.
6. Zinc deficiency in vegetables: The most intuitive manifestation is that the middle and upper leaves of the plant turn green and turn yellow, the new leaves turn irregular and have yellow spots, and the top leaves are clustered, which can easily induce viral diseases.
