Jimai 22 is a new high-yield, multi-resistance, high-quality medium-gluten wheat variety developed by Shandong Academy of Agricultural Sciences. Peixian introduced the trials and demonstrations of this species in 2007. In the fall of 2009, Pei County Peasant Station stood out in the provincial-level 10,000-mu demonstration plot in Zhanglou Town, Yulou Village, and a 1,000-acre, high-yield demonstration project was established.
First, fertilize fertile land before the cultivation of high-quality soil fertilizer 5000 kg or high-quality decomposed chicken manure 1000 kg. In the fertility of fertilization, we still need to make up chemical fertilizers for the base fertilizer. Generally, the standard nitrogen fertilizer is 16 to 20 kilograms, superphosphate 50 to 60 kilograms or diammonium phosphate 25 to 30 kilograms, potassium sulfate or potassium chloride 15 to 20 grams. Kilograms can also be applied to three or more compound fertilizers (60 to 70 kg per mu).
Second, appropriate sowing, reasonable close planting prevention and control of earthworms, cockroaches, wireworms and other underground pests, can use 25% triadimefon WP 50 grams and 50% phoxim EC 50 ~ 100 ml of water 4 to 5 kg, with Sprayer mixed with wheat seed 50 kg; Prevention of soil-borne diseases, can be used 2% active ingredient Rikenxi wettable powder 150 grams of water to 5 to 6 kg, 100 kg of seed dressing. After the seed dressing, the seeding rate should be increased by 10% and broadcasted within 4 to 8 hours. It cannot be broadcast overnight. When planting, ensure that the relative water holding capacity of the soil in the soil is maintained at 70% to 80%. In dry years or when soil moisture is poor, sowing must be done. It is necessary to change the habit of shallow (spin) tillage year after year. Deep plowing should be conducted every other year and the depth of cultivation should be 20 to 25 centimeters. The best sowing date in the local area is from October 8 to 12; the seeding rate per acre is 6 to 7 kg and the basic seedlings are 130,000 to 16 Million. Using machine seeding, spacing 25 cm, sowing depth 3 to 4 cm.
Third, the rational operation of fertilizer Fertilizer operation ratio Basic fertilizer: Miaofei: Jointing and booting fertilizer to 6:1:3 is appropriate. We will vigorously promote the application of phased fertilization and nitrogen fertilizers. Generally in the middle of the jointing stage of wheat, the application of 8 to 10 kg of urea per acre around March 15 will effectively prevent the deterioration of spikelets and florets and promote fruiting. The best application period of foliar fertilizer was wheat heading and grain filling. The main types were Xingxin fertility factor and potassium dihydrogen phosphate. For a severe defertilizer field, 500 grams of urea should be added per acre. The manual spraying of mu water consumption is not less than 50 kg, and the motorized spray fog mu water consumption is not less than 20 kg.
Fourth, the scientific use of water in the autumn drought, the end of the lack of conditions, sowing seeds to ensure that all seedlings broadcast. Low temperature and drought in winter, winter irrigation and seedlings safe winter. In the spring drought, it is necessary to combine the application of joint fertilizers and irrigation of jointing and booting water. The drought at the end of childbearing should be completed within 15 days after flowering.
V. Comprehensive Prevention and Control of Diseases, Insect Pests and Weeds For the unprepared and underground pests, gravely mix the phoxim and fine soil and sprinkle them at the base of the wheat or irrigate the ridge with 1500 times of water to ensure the whole seedlings. Controlling and weeding were carried out before and after wheat was lifted to prevent late lodging of 20% of Zhuangfeng'an Emulsion with 30-40 ml of water and 30 kg of water, and 1 gram of superstars was mixed and sprayed. For the control of powdery mildew and scab, triadimefon (8 to 10 grams per acre active ingredient) plus carbendazim (50 grams per acre active ingredient) and its compounding agents such as daffrotone can be used; Fast killing spirit, imidacloprid, cyanocyanine, etc.; for the prevention of panicle blast and sedge fly, pyridoxone (5-7.5 g per acre active ingredient) can be used.
