Phosphorus uptake by rape was the highest at the flowering stage, but it was the best for the use of phosphorus at the seedling stage for phosphorus utilization and yield increase. Since phosphorus can be used repeatedly in rapeseed, the earlier the absorption period, the greater the efficiency. The application of phosphate fertilizer can promote early growth period, the general seedling stage can be advanced 2-4 days, flowering stage 2-6 days, mature period 1-2 days. Phosphorus in rape can also increase the oil content by 0.5-2.4%. Therefore, there is a common name for "non-phosphorus-free oil." Phosphorus fertilizer consumption is generally 20-25 kilograms of superphosphate or calcium magnesium phosphate fertilizer per acre. Soils with severe phosphorus deficiency or soils with a large amount of nitrogen fertilizer should be applied in appropriate amounts. The root system of rapeseed has a special ability to absorb phosphorus. Generally, the phosphate fertilizer which is difficult to use in crops has a good fertilizer effect on rapeseed. Therefore, rapeseed can be applied to acidic soil and a type of delayed phosphate fertilizer can be applied.
When wheat is deficient in zinc, the plants are dwarfed and the leaf margins are distorted or shrunk. The veins turn from green to yellow on both sides of the veins, and yellow, white and green stripes appear on the edges. Zinc fertilizer is mostly applied with zinc sulfate. Zinc sulfate is white or light orange-red crystal, soluble in water, zinc content is 24%; while zinc chloride is white crystal and insoluble in water. Zinc sulphate is generally used as a seed dressing, soaking, dipping root or top dressing, but also for top dressing and basal dressing. From the perspective of economic benefits, spraying, dipping and dressing are effective. When zinc sulphate is sprayed or soaked, the general concentration is 0.02%-0.1%, and the seed dressing dosage is 2-6 grams of zinc fertilizer per kilogram of seed, which must be mixed with calcium, magnesium phosphate fertilizer and other fertilizers before sowing; as base fertilizer, The amount of 1-2.5 kg per 667 square meters is applied to the soil during site preparation. For top dressing, 1 kg of zinc sulfate per 667 square meters is used during the wheat seedling period, and 15-20 kg of dry soil or organic fertilizer is added. Between the lines. (laughing Liu)
Diabetes is a group of metabolic diseases characterized by high blood sugar. Hyperglycemia is due to insulin secretion defects or their biological effects of damage, or both caused. Hyperglycemia in long-term diabetes, leading to various tissues, especially the eyes, kidneys, heart, blood vessels, nerve chronic damage, dysfunction. The etiology of diabetes is roughly one is Genetic factors. Type 1 or type 2 diabetes had significant genetic heterogeneity. There is a family history of Diabetes Mellitus, 1/4 ~ 1/2 patients with family history of diabetes. Clinically at least 60 kinds of genetic syndromes may be associated with diabetes. Second, Environmental factors, eating too much, reduce physical activity caused by obesity is the most important environmental factors of type 2 diabetes, so that type 2 diabetes genetic susceptibility to individuals prone to disease. There is no cure for diabetes, but through a variety of treatment can control diabetes. Mainly includes five aspects: diabetes education, self-monitoring of blood sugar, diet therapy, exercise therapy and drug treatment. Antidiabetic drugs are needed in the patient after eating and exercise therapy and diabetes health education, blood sugar control can not be achieved when the target treatment. Most antidiabetic drugs have a greater side effect, so the patient must follow the doctor's instructions. With the succession of new antidiabetic drug patents,the patient is not only actually reducing the cost of treatment, but also increased the number of treatment options, Take greater hopes to patients with disease control.
