Our center designed according to the pre-determined wheat and peanut two-year high yield protective cultivation technology system. In 2003, we introduced and selected a new high-yielding wheat variety “Gaoyou 03â€, and achieved stable wheat production for three consecutive years. Based on the earlier target of 500 kilograms per mu and 400 kilograms per mu of summer peanuts, in 2006, 6.4 mu of wheat yielded 591.3 kilograms, the highest point reached 669.8 kilograms, and the summer yield of peanuts reached 432 kilograms. In 2007, the wheat yield reached 567 kilograms and the highest point reached 652 kilograms. The growth and growth of summer peanuts were better than last year. Observations and examinations for five consecutive years have demonstrated that many characteristics of “Gaoyou 03†wheat have reached or exceeded the expected target: spring rate, especially spring tillering, has a high rate of spike formation; lodging resistance, especially the basement cavity is small, and the wall thickness is tough; It is resistant to cold; resistant to diseases, especially the "three rust" and sheath blight; drought-resistant, especially resistant to dry hot wind; early maturity of 5-7 days, etc., are better than the current other varieties. The variety is a hard grain high quality wheat.
I. Yield composition factors and dynamic indicators of fertility were sown on October 20 in both 2006 and 2007. There are 93,300 basic seedlings and 86,100 seedlings per acre (seedings of 4.5 kg and 7 kg), and the total number of stems before the winter (December 1st) is 506,000 and 467,000. On March 1st, there were 521,200 and 470,000. In the spring, the highest total number of stems was 1.026 million and 980,000, and the average mu was 39.7 million and 402,000, and the number of grains per ear was 39.43 and 40. Twenty-one grains, a thousand grain weight 39.21 grams and 38.46 grams; the highest point mu number of 416,000 and 408,700, 39.4 grains and 38.7 grains per spike, a thousand grain weight 40.86 grams and 39. 97 grams.
Second, sowing basis 1. Land preparation. After the harvest, the former crops were sown after deep harvesting and they were sown. 2. Fertilization. Mai Xi “in fetal rich†added base fertilizer is the basis of high yield in wheat, the center of our center for three consecutive years, wheat straw, wheat bran all direct return to the field (also can be applied 3000-4000 kg of organic fertilizer per acre), the former crops summer peanuts Combine 50 kg of ammonium bicarbonate and superphosphate with arable land in Mushi after harvest. Combine sowing with 15% of N, P, and K of Mushi and 40 kg of compound fertilizer with appropriate amount of trace elements in joint planting. Apply 20 kg of urea in jointing stage with watering. .
Third, sowing 1. Sowing period and sowing amount. The peninsula area October 1st to 15th, Luzhong and Luxi from October 10 to 25th. Our center has been around the 20th of October. The seeding rate is controlled at 5-8 kilograms per acre, ensuring 10-15 million basic seedlings. In order to prevent seed, soil, and fertilizer from spreading diseases, it is imperative to quickly emerge seedlings and seedlings to resist diseases, and emphasizes the use of “Weifu†seed dressings with a seed weight of 0.25% (ie, 25 ml per bag mixed with 10 kg of seeds). One kilogram per acre of “immortalized groundworms†was used to prevent the damage of underground pests, seedlings, leafhoppers and their spread. 2. sowing. With precision seeder, about 3 meters wide broadcast 16-18 lines. Emphasizing the planting of enough planting should be done with enough water and water, and the depth of sowing should be about 3 cm. Avoid sowing too deeply.
Fourth, the field management should be promptly after the sowing of rain or buckwheat buckwheat in the consolidation, four-leaf spray herbicide and foliar fertilizer. "Flying winter" to "little snow" spray a foliar fertilizer, pouring water before the winter. When the soil is thawed during the spring season, the top of the ridge is buckwheat or ploughed, and the surface is dried and then repressed. Get up and spray 1-2 times foliar fertilizer during jointing. At the beginning of jointing (Peninsula area before and after the Ching Ming Festival), pouring enough water and water, using watering to spread about 20 kg of urea and about 1 kg of “quick exterminator†medicine powder. After watering, the fertilizer grows and flourishes, and maggots and powdery mildew begin to be harmed. Therefore, it is necessary to spray and control insecticides and fungicides in time. After the panicles are all raised, the leaf area reaches the peak, the temperature rises, the light is sufficient, and the transpiration of the leaves increases. It is necessary to spray 1-2 times of systemic insecticides and protective fungicides to prevent locusts and rust, and reduce leaf surface area. Transpiration. The center sprayed "high-yield peanut film" and "great success" to effectively prevent late spring, dry hot wind and late-stage diseases, and increase grain solidity.
V. The harvest of “High-quality 03†wheat has good yellowing, and it is necessary to grasp the harvest during the waxing stage. It is not only for squashing peanuts but also for early detoxification, while maintaining high yield and good quality.
