Honey 236 super sweet corn is super sweet corn, hybrid, high quality, high yield, early maturity. Sowing in Yunnan, the plants are neat and dwarf, with short internodes and low panicles. They can receive green ears 65 to 85 days in the season. Standardized planting management, a good planting area in warm water and fertilizer, per mu 1200 to 1500 kilograms. Fresh grain yellowish, sweet and crisp, nutritious, cooked food: raw or frozen processing.
1. Soils with adequate light, soil thickness, lyrical and fertility are selected for suitable environments, and are isolated from other maize (400 meters apart or 30 days of wrong flowering period). The earliest sowing date can be started when the temperature smoothly passes 12°C, and the latest sowing date must ensure that the temperature during pollination and harvesting is above 18°C, and refers to the local sowing date of maize. The most suitable temperature is from the seedling stage to the jointing stage of 18°C ​​to 22°C, and the big bellmouth stage to the tasselling stage at 22°C to 26°C. Temperature above 35 °C or below 18 °C is not conducive to pollination.
Second, planting density 3500 per mu, ridge planting. (1) Wide and narrow row planting, big line 100 centimeters, small line 50 centimeters, plantlets per plant, spacing 25 centimeters. (2) Single row planting, spacing 75 centimeters, plantlets per plant, plant spacing 25 centimeters. If the planting density is too high, it will affect the yield and quality.
Third, nursery transplanting preparation of nutritious soil (with half of rotten manure and fine mature soil, 1% of urea and superphosphate, mixed with wet), nursed with nutrition ball (bag, block), soil with 3 leaves Planting and pouring enough water to ensure Miao Qi, Miao Zhuang. Directional planting (line north-south and leaf-to-east) is conducive to increased photosynthetic efficiency. Covered with plastic film or film side of the cultivation, can increase the temperature and protect the earthworms.
Fourth, the field management to use the base fertilizer: acres of farmyard manure 2000 to 3,000 kg, plus 50 kg of superphosphate, 15 kg of potassium sulfate, zinc sulfate 2 kg, mix well, pile up after maturity, deep ditch 10 cm, cover soil 5 cm, replanted or directly sowed. Timely top-dressing cultivator: 4 to 5 leaf-stage light-seeding seedlings, Mushi urea 5 kg, foliar spraying 0.2% potassium dihydrogen phosphate 2 times, shallow cultivator loose soil. 7 to 8 leaf joints to large bell-mouth heavy ear fertilizer, urea 25 kg of urea, deep cultivator soil. Protect the seedlings from flooding, prevent flooding during the seedling stage, keep the soil moist during the tassel filling stage (in case of drought, it must be re-watered), and timely weed control and pest control.
V. Harvesting and harvesting Generally, green ears can be harvested 20 to 25 days after pollination. At this time, the grain ripening period, the temporal green leaves, filaments brown, full grain, thin skin, high sweetness, is the best harvest period. The harvest period for off-season planting will generally extend for several days. The harvested green shoots should be placed in a cool and ventilated place and listed or processed in time. The tassels shall be bagged (framed) and ventilated at close quarters. The green tassels transported for a long distance shall be packed and iced to keep the green leaves and the seeds fresh and sweet.
6. Prevention and control of pests and diseases According to local conditions of diseases and insect pests, prevention and control will be conducted under the guidance of agricultural personnel. For diseases such as spot disease and corn borer, pay attention to early prevention and treatment. General use of carbendazim, Trichoderma special, leaf spot clear spray, can prevent spot disease, with phoxim granules in the big bell mouth irrigation, can control aphids. Pesticide control should ensure that the pesticide residue is lower than the national standard.
Seven, matters needing attention
1. The coating species cannot be eaten and fed, so it cannot be soaked or dressed. It should be cleaned promptly after sowing.
2. Must be planted in isolation from other corn, to avoid the influence of string powder on the taste and quality of the product.
3. For the lack of farmyard fertilizer, appropriate amount of compound fertilizer should be added as base fertilizer. When sowing, it is necessary to plant seedlings in shallow depth and cover fine soil 2 to 3 centimeters. Seeds must not be exposed to potash, otherwise it will reduce the emergence rate.
4. This product is not seedlings. For live film, seedlings should be promptly ruptured and filmed after emergence; for transplanting seedlings, filming must be carried out when the film is covered, and water and fertilizer management at the seedling stage must be strengthened, otherwise the seedlings will be burned or the production will be reduced.
5. The plants grow vigorously, and tillers and spikes are normal. However, tillers and multiple spikes should be removed promptly; only one or two spikes at the top of each plant can be preserved. If more leaves are kept, the yield and quality will be reduced. Pulled young ears can be made sweet corn shoots.
6. When the tasseling and flowering period is in the rainy season, artificial pollination should be selected at sunny hours from 9 to 10 o'clock in the morning to prevent and reduce the tip of baldness.
7. Grains grown from this variety cannot be used as seeds. (Kunming Xingnong Seedling Co., Ltd.)
