As we all know, there are 16 kinds of nutrients necessary for the growth and development of general crops, namely: carbon (C), hydrogen (H), oxygen (O), nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulfur (S), iron (Fe), boron (B), manganese (Mn), copper (Gu), zinc (Zn), molybdenum (Mo), chlorine (Cl), all of which are indispensable. The role of various nutrients in the plant is equally important and irreplaceable, and the lack of any nutrient will affect the yield or quality of the crop.
Today we talk about the function of zinc (Zn) in the process of crop growth and development, and the symptoms and countermeasures of crop zinc deficiency (Zn):
1. Symptoms of zinc deficiency (Zn) in crops:
Zinc is the key factor in the synthesis of auxin in crops, so when plants are deficient in zinc, they will show: plants are short, leaf differentiation is hindered, and deformed growth; when many plant seedlings are deficient in zinc, "microlobar disease" occurs, sometimes in clusters, and the leaves are green and yellow, with brown spots, and gradually expand into tan necrotic spots.
Crops in the production process is inseparable from the supply of zinc elements, zinc elements play an important role in promoting the quality and yield of crops. The occurrence and prevention of physiological diseases caused by zinc deficiency have attracted more and more attention.
Zinc deficiency in rice: slow growth at the seedling stage, rigidity, local appearance of dead seedlings, leaf color is thick green, new leaves are short, the base is whitish, the whole leaf of the old leaf appears brown spots, sometimes connected into strips, the growth period is delayed, and the panicle extraction is delayed.
Zinc deficiency in maize: the middle and upper part of the leaf veins lose green, appear pale yellow and light green stripes or appear striped yellow patches, prone to "white seedling disease", delayed fertility, zinc excess is easy to poison, new leaves lose green and yellow, wrinkles and curls.
Zinc deficiency in leafy vegetables: the new leaves of vegetables are born abnormally, with irregular loss of green, and yellow spots.
tomato
chili pepper
Zinc deficiency in tomatoes and green peppers: it is a small leaf cluster, the new leaves have macula, the macula gradually expands to the whole leaf, and it is also susceptible to viral diseases. Tomato zinc deficiency growth is weak, first the leaf surface appears macula, the leaves are twisted, the macula gradually expands, the whole plant is yellow, the branches and leaves droop, and finally scorched, the fruit is small.
Eggplant zinc deficiency: The plant is shorter, the top leaves are thinner and longer, the sides are rolled upwards, and the lower leaves are largely green, or even completely green.
Cucumber zinc deficiency: poor growth, from the edge of the old leaf began to yellowing and zooming, gradually inward irregular expansion, the appearance of small yellow spots on the leaves, the fruit is short and thick, the skin forms a coarse green fine white stripes, lighter green.
Zinc deficiency in fruit trees: The specific symptom of zinc deficiency in fruit trees is "leaflet disease", there is less tryptophan when zinc deficiency, tryptophan is the raw material for synthesizing auxin indoleacetic acid, which leads to a decrease in auxin, affecting leaf growth, causing leaflet disease and cluster leaf disease, zinc is related to the synthesis and stability of chlorophyll, and leaves are yellowed when zinc is deficient. Zinc deficiency fruit trees are the most obvious!
Apple zinc deficiency: the most typical, which is characterized by abnormal growth of new shoots, extreme shortening, morphological distortion, axillary buds sprouting, the formation of a large number of thin and thin twigs, small and hard spotted leaves near the tip ends, densely formed into a fungus, so also known as "cluster leaf disease", the degree of cluster growth and the degree of zinc deficiency in the tree body is positively correlated. The fruit is often deformed and has little edible value.
Grape zinc deficiency: short between new shoots, small leaves, yellow flowers between leaf veins, dry and fall off in severe times, a large number of seedless small fruits are formed on the fruit spikes, and the yield is significantly reduced.
2. New method of crop zinc supplementation (Zn) - "fish + zinc":
Zinc (Zn) is an essential element for crop growth, zinc deficiency will cause immeasurable losses in crop yield and quality, so how can zinc be scientifically supplemented so that crops can obtain sufficient zinc?
Below, the author introduces a new scientific method of efficiently supplementing zinc for crops: that is, "fish + zinc"
Everyone must be curious? What exactly does fish have to do with zinc? First of all, let's first look at what kind of fish the author said about "fish"?
Fish has a high nutritional value and is also one of the favorite foods of human beings, because fish is rich in protein and unsaturated fatty acids, and eating more fish is good for health. What is more interesting is that they, the expert scientific research team of Xintianlong Special Fertilizer, use deep-sea fish as raw materials to obtain nutrients - fish protein through bioenzymatic degradation technology, and the application to crops reflects the advantages of high value.
Fish protein: Rich in free radicals and collagen nutrients, it also contains catalysts such as enzymes that catalyze plant cells and soil roots, activating soil roots, making crop roots developed and growing strongly.
Fish protein contains a large amount of unsaturated fatty acids, which are used on the plant body to form a fat protective layer, which can only freeze at lower temperatures.
Fish protein foliar spraying thickens the leaves so that bacteria and fungi cannot invade, which can effectively prevent and alleviate diseases such as powdery mildew, downy mildew, root and leaf diseases, and can also alleviate soil-borne diseases such as root-knot nematodes.
Fish protein has a special odor, and after spraying, it can make the surface of the plant shiny and shiny, because it can avoid pests such as aphids and whitefly.
Pests and diseases, fungal pests have always been a worry in the hearts of every farmer, the reduction of crop yields, crop harvest loss... Faced with these problems, how do we solve them?
Fungal infestations on vegetables
Fungal infestations on fruit trees
Bacterial infestation of melons and legumes
Prevent diseases and insect pests, increase crop yields, make crops harvest, crops indispensable zinc, indispensable fish protein. Xintianlong special fertilizer "new product" foliar fertilizer - fish propylene zinc, rich in fish protein, with fish protein as the carrier to improve the utilization rate of zinc, reduce the waste of foliar zinc supplementation, add deep-sea pollution-free fish to extract fish protein, after low temperature plus centrifugal chelation, four-stage temperature difference treatment, its fish protein extract ≥ 30%, zinc ≥ 10%, can improve crop yield seed germination, fruit preservation, strong flowers, improve fruit quality, stimulate root tip growth, improve crop marketability has a significant effect, but also improve crop oxidation resistance.
It is not only foliar fertilizer, but also a preventive fungicide, only the organic combination of fish protein zinc, in order to play a safer and more efficient role, to prevent crop zinc deficiency, the disease can better play a bactericidal effect, the real zinc tonic disease prevention is not wrong, so that your crops fully zinc and disease prevention. What's more, it is the only powder foliar fertilizer that can be used during the coloring period!
