Scope

Scope: This standard specifies the selection of growing environments for double-season green corn, the choice of varieties, main agronomic measures, and product quality, etc. This standard applies to double-season green corn planting areas in Jiangsu Province and similar ecological regions. Main technical content: 5. Spring planting green corn cultivation techniques 5.1 Sowing 5.1.1 Sowing period: In the Yangtze River Delta region, film-covered cultivation is generally carried out from March 20 to 25. 5.1.2 Tillage and application of base fertilizer: After harvesting the previous crop, timely clear away straw and weeds. Apply 1,500 kg of composted organic fertilizer and 40 kg of high-concentration compound fertilizer per 667 m2. For plots with severe underground pests such as gold needleworms and grubs, apply 0.25 kg of 75% phoxim emulsion mixed with 20 kg of fine soil per 667 m2 and incorporate it into the soil during tillage. Tillage depth should be 20-25 cm, and fine leveling should be carried out to ensure that the fertilizer and soil are mixed evenly. 5.1.3 Variety selection: Select high-yielding, high-quality, and suitable maturity varieties such as Nanong Ziyumu 1 and Shumu 3. 5.1.4 Sowing method: Sow when the soil is suitable for planting. The row spacing is 1.33 m, and the sowing grooves are 5 cm deep. The depth of the sowing grooves should be consistent. If the soil moisture content is insufficient, water the seeds during sowing. Use a single row with two plants per hole, with a planting distance of 20-25 cm per hole and three seeds per hole. After covering the soil, spray Golden Dew insecticide at a dosage of 70 ml per 667 m2 mixed with 40 kg of water and cover the soil with film. Open drainage ditches in time after sowing to ensure that the three ditches are compatible and can drain and irrigate. 5.2 Field management 5.2.1 Breaking the film and transplanting seedlings: Transplant seedlings promptly after they emerge, generally before 9 am and after 4 pm.
