Pictures and prevention methods of boron deficiency in grape

What is boron deficiency in grapes like? What causes boron deficiency in grapes? How to prevent boron deficiency in grapes? Netizens with experience in grape cultivation are also asked to introduce grapes as perennial lianas, which are generally cultivated in greenhouses or equipment scaffolding, resulting in the vineyard soil being unable to plough for a long time, resulting in the deposition or loss of elements in the soil. resulting in symptoms of element deficiency. Today, the farming network has sorted out the harm, causes and prevention methods of boron deficiency in grapes, which are listed in detail below for netizens' reference. The harm of boron deficiency in grape: when the grape is boron deficient, the grape plant is short, the accessory shoot growth is weak, the Internode becomes shorter, and the terminal bud is easy to die. When the grape was boron deficient, the young leaves at the top of the new shoots appeared yellowish spots, and the leaves became smaller, thickened, brittle, wrinkled and bent downward. When the grape is boron deficient, the leaf edge appears chlorotic macula, and then the edge becomes a piece, which makes the tissue between the leaf veins turn yellow, and finally turn brown and die. When the grape is boron deficient, the leaves near the inflorescence appear irregular light yellow spots, and gradually expand, and when the leaves fall off seriously. When the grape is boron deficient, the inflorescence is small, the buds are few, the Corolla often does not fall off during flowering or the florescence is serious, at the same time, the seedless small fruit in the grape ear increases. And when the grape is boron deficient, the root distribution is shallow, and the root is easy to die. The cause of boron deficiency in grape: boron belongs to trace elements, which is mainly involved in cell division, growth, tissue differentiation, cell wall formation, enzyme activity and carbohydrate transport. The occurrence of boron deficiency in grape is mainly related to soil structure and soil organic matter content. Boron deficiency is serious in barren soils lacking organic matter, arid areas, alkaline soils with pH as high as 7.5-835 and sandy soils that are easy to dry. At the same time, the shallow distribution of grape roots is damaged by nematodes, which leads to poor root absorptive capacity and boron deficiency. Click to see the methods for the determination of soil acidity and alkalinity, the harm of nematodes, the prevention and treatment of boron deficiency in grapes: method 1. Increase the application of high-quality organic fertilizer to the vineyard to improve soil structure and increase soil fertility. Method 2. Timely watering the grapes to increase the content of soluble boron in the soil and facilitate the absorption of grapes. Method 3. When applying basal fertilizer in the vineyard in autumn, each adult grape was topdressing with 50 grams of borax or boric acid to supplement the deficiency of grape boron. Click to view the "effect of boron fertilizer" method 4. Spray 0.1%-0.3% borax (boric acid can be replaced by boric acid) solution twice in a week before flowering and in full bloom.
