Wheat jointing and heading management measures

The application of "three fats" began to gain weight in front of the growth of wheat, low-density weak seedlings must be timely to recover from the body fat, generally 10 to 15 days before the joints to recover 7 kg of urea. Strong seedlings and Wang Miao do not apply fertilizer. The amount of fertilizer applied is related to the fertility of the varieties and the early growth of the plants. It has reached the standard of strong seedlings and can recover 3~5 kilograms of urea per mu. Wang Miao does not apply, weak seedlings appropriate increase. Where no panicle fertilizer is applied to the panicle fertilizer, when the panicle has a deficiency, the panicle fertilizer is to be applied. Generally, 2 to 3 kg of urea is recovered per mu. Drainage against waterlogging Wheat waterlogging is caused by surface water, shallow water and groundwater, among which shallow water hazards are the greatest. Therefore, it is necessary to reach a straight ditch at the end of the ditch, so that the ditch and ditch can communicate with each other, so that the rain will stay dry, the rain will be clear, the dark water will be drained, the groundwater will be reduced, and the conditions for soil ventilation will be improved. This will create a good soil environment for the growth of wheat under rainy conditions. Lodging of the lodging-prevented wheat mostly occurs after heading, but the cause of lodging is formed from the jointing stage to the booting stage. When the medium and high fertility and high-density plots begin to elongate between the first internodes of the base of wheat, each acre With 15% paclobutrazol WP 8 grams, sprayed with 75 kg of water, can play a dwarf effect, while promoting production. Prevention and control of pest diseases is mainly to prevent wheat scab, rust, powdery mildew, and armyworm, aphids and other hazards. In the flowering period of wheat, use 40% carbendazim gum suspension 75 ml and 15% triadimefon (triadimefon) powder 75 g/mu or so, and spray 40 to 50 kg of foliar spray for comprehensive prevention and treatment. When the disease is serious, spray it once every 7-10 days. Insect pest control methods Wheat aphids: When the ear of axillary panicles amount to 500 heads with 10% imidacloprid wettable powder 60 g / acre, watering 40 ~ 50 kg foliar spray, interval 10 ~ 15 days heavy spray 1 time . Acetamiprid and chrysanthemum pesticides can also be used for control. Wheat spiders: When the wheat field has a single row of 33 cm long wheat spiders up to 500 heads, use 20% chlorindone emulsifiable concentrate about 60 ml/mu, and dilute 40 to 50 kg of foliar spray. After top dressing, dressing fertilizer outside wheat roots can increase the seed setting rate and 1000-grain weight, accelerate the maturation process of wheat, shorten the growth period of 1 to 2 days, and generally spray potassium dihydrogen phosphate, superphosphate leachate, and ash leaching liquid before milk ripening stage. A small amount of nitrogen fertilizer can also be added. 0.2% potassium dihydrogen phosphate solution 1 ~ 2 times, once every 7 to 10 days.

[Composition]

The main component of this preparation is human immunoglobulin, which is prepared by cold ethanol fractionation of human plasma from healthy donors. The manufacturing process contains a step to remove anticomplementary activity and a dual viral inactivation process. It contains a suitable amount of glucose or maltose as stabilizer (see table below), but does not contain any antiseptic or antibiotic. The distribution of IgG subclasses is close to the serum level of normal subjects and maintains the bioactivity of Fc fragment of IgG.

[Indications]

1. Primary agammaglobulinemia, such as X-linked hypogammaglobulinemia, common variant immunodeficiency diseases, immunoglobulin G subclass deficiency, etc.

2. Secondary immunoglobulin deficiency diseases, such as severe infection, septicemia of newborn, etc

3. Autoimmune diseases, such as primary thrombocytopenic purpura, Kawasaki disease
