The fruit corn Huatian No. 1 has good cultivation efficiency in autumn
Xinshao County has introduced the super sweet corn combination hz5008 (now officially named Huatian No. 1) from Huazhong Agricultural University for spring maize and autumn corn cultivation. The performance is characterized by high uniformity of the ear, commodity rate above 95%, grain size. Yellow and white, neatly arranged, not bald, beautiful appearance; thin peel, crisp texture, high sweetness, is the sweetest type of sweet corn in Xinshao (combination); with creamy taste, no residue of food, Good flavor and taste, suitable for both raw and cooked food. In 2001, Hucheng Village, Yantang Town, Xinshao County, cultivated it in autumn, covering an area of ​​102 acres, and generally obtained better results. The rest of the growing period is only 65-70 days, and 500-600 kilograms of fresh sticks are produced per mu, which has been snapped up by units and fruit vendors. The price per kilogram is about 2.5 yuan, and the per mu output value is 1000-1500 yuan, 600-900 yuan more than the late rice. Now we will organize our cultivation experience as follows. Selection of land. Choose fertile, loose soil for planting. For the cultivation of autumn corn needs drought resistance, so the land must be planted near the water or have certain irrigation conditions. In order to preserve the quality and security, it is separated from other corn varieties by more than 200 meters. Time isolation can also be used, and the flowering pollination period differs by more than one week. Timely sowing. Sowing time depends on factors such as expected time to market and climate constraints. In Xinshao, they are usually planted from July 20 to August 15, broadcast in batches in stages, broadcast batches every 5 days, and staggered listings in a centralized manner to reduce sales pressure. Use 500-600 grams per acre. In order to increase the rate of seedling emergence and seedling emergence, soaking in cold water for 6-8 hours before sowing, filter out with gauze for 1 day and 2 nights, moisturize and germinate. During the period of time, you should pay attention to turning, and after the 1 day and 1 night of the package, you should eat water for 30 minutes. After eating the water, pack it again for 12 hours to see the buds. Live or seedling transplanting. Compared with the provincial government, live broadcasting: Daejeon applied enough base fertilizer to produce 3-4 meters in width and open a trench to facilitate irrigation and drought relief. According to the row spacing of 55 cm, planting spacing of 30 cm insertion; plastic floppy seedlings for easy centralized management, high seedling rate: select the water source for the seedbed, leveling the bottom, ready for nutrition, set the floppy disk, with 60 holes per acre plastic Floppy disk 65-70 sheets, before sowing, spray water through the bottom of the bed, according to the three vertical or two sideways plate, the plate and the plate close up or edge, without revealing the gap. Sowed in nutritious soil, the thickness accounts for 2/3 of the holes, sowing 2 seeds per hole, leaving 1 seedling. After sowing, sprinkle with a layer of nutritious soil cover, flush with the floppy disk, watering, cover with straw or straw, soil around the seedbed to suppress the edge of the pan to prevent exposure to the bottom. Due to drought and rain at the seedling stage, we should pay attention to watering, keep the soil moist, and ensure that the seedlings are neat and tidy. After the emergence, the cover was peeled off and watered once every morning and evening. When the seedling age was about 15 days and the leaf age was 2-3 leaves (based on the leaf age), the soil was transplanted with earthworm. Daejeon transplanted. Daejeong Shizu base fertilizer, per acre applied to compost pig cow pen manure 1000-1500 kg, cake fertilizer 40-50 kg, 30 kg of phosphate fertilizer, potash 10-15 kg or compound fertilizer 50 kg. In accordance with the width of 3-4 meters to deliver, after fine soil preparation, select sunny afternoon or cloudy transplanting. After the frost watering. Field management. After transplanting, it should be diligently watered, and after easing the seedlings, the seedlings should be re-applied in combination with cultivator, and 15 kg of urea per mu should be applied to the thin fertilizer. When rain and drought are raining, it is necessary to promptly remove the tillers during the seedling period. Jointing period, per acre with 15 kg of urea on the water application or acupuncture, seedlings with the enemy to kill the control of tigers, large bell-mouth period with the enemy to kill or bt insecticide solution heart to prevent corn borer. During the tasselling period, spraying with jinggangmycin to control sheath blight was applied twice. Huatian No. 1 only retains one commodity ear per plant, and should remove more than eight fruit spikes in the pollination period 15-20 days before harvest to avoid consumption of nutrients, but not to damage the leaves. Harvested in time. The grain development is about 55% moisture content during the milk period, which is the best harvest period, that is, 15-20 days after pollination, the suitable period is about one week, and premature or late harvest will affect the quality. In order to prevent the conversion of sugar, the harvested Qingsui is listed on the market in a timely manner, together with the harvested storage of the bales to extend the shelf life.
