Characteristics: Transgenic insect-resistant genetic hybrids, the spring sowing period of the spring in the cotton region of the Yellow River Basin is 120 days, the emergence is late, the seedling growth is weak, the growth is strong in the middle period, the growth in the latter period is weak, and the leaf function is general. Plant type compact, plant height 100 cm, medium leaf size, dark green, first fruit branch position 7.5 knots, 17.6 bolls per plant, bolls oval, boll opening smooth, boll weight 6.0 g, clothing fraction 41.6%, The child refers to 10.1 grams, and the pre-frost rate is 96.5%. Resistance to Fusarium wilt, resistance to Verticillium wilt, resistance to Helicoverpa armigera; average length of the upper half of HVICC fiber 30.4 mm, fracture specific strength 31.2 centi-Nx/Tex, micronaire value 4.5, elongation at break 6.3%, reflectance 74.6% The yellow depth is 7.2, the uniformity index is 85.4%, and the spinning uniformity index is 155.
Cultivation techniques: 1. Covering with plastic film or transplanting seedlings. When the soil temperature of 5 cm stabilizes at 15 °C, the live cotton field will be planted in mid-late April. Seedlings will be transplanted and planted in early April. 2. General ground cotton planting density of 2000 acres per acre. 3. Apply base fertilizer adequately, reapply flower and bell fertilizer, and spray foliar fertilizer at the discretion of the later stage; base fertilizer is mainly organic manure, apply nitrogen fertilizer stably, apply appropriate phosphorus and potassium fertilizer, apply micronutrients as appropriate, and implement balanced fertilization. 4. According to the growing appearance of cotton, grasp the principle of a few times, timely control. 5. The second-generation H. armigera in general years does not need to be controlled, and the third and fourth generations of H. armigera should be controlled as appropriate when they meet the control standards; other pests should be prevented and treated in time. 6. Under adverse climatic conditions, comprehensive prevention of wilt and Verticillium wilt should be strengthened.
Validation opinion: This species has obtained the safety certificate for production and application of agricultural genetically modified organisms (name of genetically modified organism sGKz32 (Xinqiu No. 2)), which meets the national cotton variety certification standards and has passed the validation. It is suitable to be planted in spring in the Yellow River Basin in the north of the Huaihe River in southern Hebei, central and southern regions, Shandong, Henan, northern and central regions, Jiangsu Province and Anhui Province. It should be strictly in accordance with the safety certificate for agricultural genetically modified organisms. Range promotion.
