Molybdenum deficiency: first occurs in the front part of the leaf, the leaf color is green, and then on the whole leaf of the lower part of the heart leaf, small, yellow-white stains appear along the veins in parallel, and gradually become linear and flaky. Finally, the front part of the blade is dry and the whole whole leaf is dry.
This type of molybdenum deficiency occurs mostly in acidic soils, especially in wheat fields where sand or chemical nitrogen fertilizers are applied. After the onset, 0.05% ammonium molybdate solution can be used, and the leaves are sprayed 2~3 times, and the interval is about 10 days.
Manganese deficiency: Wheat is sensitive to manganese, and high-yield wheat fields are more likely to be lacking. Manganese deficiency is mainly caused by chlorosis in the upper part of the plant and white streaks between the veins, commonly known as "white strips". For remediation, use 0.05~0.1% manganese sulfate solution 50~75 kg per 667 square meters, and spray the leaves 1~2 times. Note that the concentration used should not be too high.
Boron deficiency: The wheat is deficient in manganese, the leaves of the plants become thicker, and the upper leaves are distorted. The leaves are brittle and fragile, and the roots of the roots become black. The apical meristem of the plant died and the top branching occurred. The filaments are stretched and the tillers are not normal, the pollination is blocked, and there is "no panicle".
Wheat deficiency of boron, usually in the soil with an effective boron content of less than 1 ug / ml, will occur. In the prevention and treatment of boron deficiency, in addition to 0.5~1 kg of borax per 667 square meters before planting (mixed evenly in superphosphate as base fertilizer), it can also use 0.02~0.025% boric acid in wheat tillering and jointing stage. , or 0.03~0.05% borax solution for foliar spraying, 509 kg per 667 square meters each time, can effectively prevent wheat "no panicle" and improve the seed setting rate of wheat.
Zinc deficiency: Zinc deficiency can inhibit the growth and development of wheat until it stops growing and causes certain diseases.
Zinc deficiency in wheat is prone to occur in zinc-neutral neutral, calcareous and leaching acidic sandy soils and in paddy fields that have just returned to drought due to long-term flooding. The control can be carried out by spraying 0.02~0.2% zinc sulphate solution during the growth of wheat, 25~50 kg per 667 square meters, and spraying 2~3 times. Note: Zinc sulphate cannot be mixed with phosphate fertilizer during spraying or topdressing.
During the growth and development of wheat, the nutrient metabolism inside the plant is often destroyed due to the lack of certain nutrients, and the symptoms of deficiency are manifested outside the plant.
