What are the disadvantages of Rice E 11? When is planting? How to cultivate?
What are the disadvantages of Rice E 11? E No. 11 is a premature mutated single plant selected from the Xiaonan District Agricultural Bureau and the Xiaogan City Quality Agricultural Products Development Company from the Jiaxing Agricultural Science Research Institute of Zhejiang Province. The shortcomings of this variety are: easy to infect the disease, in the hot weather, sensitive to potassium deficiency, the leaves have red rust symptoms, but the symptoms will gradually fade after the temperature is lowered. I. Characteristics of rice E night 11 1. High yield: The rice variety E No. 11 variety participated in the provincial regional experiment, with an average yield of 444.27 kg per mu. Since the selection, the variety has been tested in the same area in Xiaonan District, with a weighted average yield of 442.3 kg per mu, which is 9.7% higher than that of Eyi 105. 2. Moderate growth period: The rice variety E late 11 is a late-maturing mid-maturing type, which can be planted for double nights. The whole growth period is 128-132 days, 2-4 days later than Eyi 105. 3, excellent quality: rice E night 11 varieties brown rice rate of 83.55%, the whole polished rice rate of 67.78%, aspect ratio of 1.9, amylose content of 16.43%, rice grain products good appearance, good food, reached the national standard high quality glutinous rice standard. 4, strong resistance: rice E 9 is a high resistance to rice blast, resistant to white leaves, sheath blight is light, suitable for medium and high fertility field planting. In the late stage of planting, it has good cold resistance, strong adaptability and good stability. 5. Compact plant type, grain-grain coordination: The leaves of rice variety E late 11 are narrow and thick, with dark green leaves, strong tillering power and high seed setting rate. For double nights, the plant height is 80-90 cm, the effective ear per acre is 25-260,000, the total grain of the ear is 80-85, and the seed setting rate is over 80%. Second, the cultivation techniques of rice E night 11 1. Sowing at the right time, cultivating the strong and sturdy: as a season, the late rice is planted in May, and the age is 30 days; the double-season late rice is planted on June 15-20, and transplanted on July 20-25, 35 days old. Seed treatment before sowing, soaking seeds with strong chlorine to prevent disease. Miao Honda uses 5-6 kg of seeds, and the seeding amount per mu is 0-35 kg, 1 leaf 1 heart spray paclobutrazol, promotes short and strong tillers. Putian should apply the base fertilizer, and timely chase the weaning fertilizer and promote the manure fertilizer to cultivate the belt. 2, the basic seedlings inserted: plant planting distance is 13.2 × 16.7 cm, planting 5-6 seedlings per hole, inserting more than 150,000 basic seedlings per acre. 3. Scientific management of fertilizer and water: The rice variety E E11 is suitable for field cultivation with high fertility. The medium fertility field should be applied with 11-12 kg of pure nitrogen. At the same time, it is necessary to increase the application of phosphorus and potassium fertilizer. The specific fertilization method is as follows: apply ternary compound fertilizer (N12, P5, K8) 50 kg per acre to add 20 kg of ammonium carbonate as the base fertilizer. After 4-5 days of transplanting, 5 kg of urea per acre is used to promote manure. After reclaiming water in the sun, 8 kg of potassium chloride is chased per acre to promote the stalks. Spray the potassium dihydrogen phosphate 1-2 times on the leaf surface after the heading to promote the fullness of the seeds. In the pipe water, the water is inserted into the green, the water is shallow, and the wet management is in the later stage. 4, prevention and control of pests and diseases: pay attention to the prevention and control of pests such as stem borer, stem borer, leafhopper, flyhopper, etc., spraying 1-2 times of Jinggangmycin against rice stalk and rice smut in the booting to heading stage.
