Characteristics: the growth period of spring sowing in the Yellow River valley was 120 days, the seedling emergence was late, the seedling growth was weak, the growth was strong in the middle stage, the growth became weak in the later stage, and the leaf function was general. The plant type is compact, the plant height is 100 cm, the leaf is medium size and dark green, the first fruit branch is 7.5 nodes, there are 17.6 bolls per plant, the bolls are oval, the bolls are smooth, the single boll weight is 6.0 grams, the lint percentage is 41.6%, the seed finger is 10.1 grams, and the flowering rate before frost is 96.5%. Resistant to Fusarium wilt, Verticillium wilt, cotton bollworm; the average length of the upper half of HVICC fiber is 30.4mm, the breaking specific strength is 31.2 N / Tex, the micronaire value is 4.5, the elongation at break is 6.3%, the reflectivity is 74.6%, the yellow depth is 7.2, the evenness index is 85.4%, and the spinning evenness index is 155.
Key points of cultivation techniques: 1. Plastic film mulching or seedling transplanting, when the ground temperature of 5 cm stably passed 15 ℃, the direct seeding cotton field was sown in the middle and last ten days of April, and the seedlings were planted in early April. two。 The planting density of general fertility cotton field is 2000 plants per mu. 3. Sufficient application of base fertilizer, heavy application of flower and boll fertilizer, spraying foliar fertilizer in the later stage; base fertilizer is mainly organic fertilizer, stable application of nitrogen fertilizer, appropriate application of phosphorus and potassium fertilizer, micro-fertilizer, balanced fertilization. 4. According to the growth and appearance of cotton, we should master the principle of a small number of times and carry out chemical control at the right time. 5. In general years, the second generation cotton bollworm does not need to be controlled, the third and fourth generation cotton bollworm reaches the control target, and other pests are controlled in time. 6. Under adverse climatic conditions, the comprehensive control of Fusarium wilt and Verticillium wilt should be strengthened.
Approval opinion: this variety has obtained the safety certificate for the production and application of agricultural genetically modified organisms (the name of genetically modified organisms is sGKz32 (Xinqiu No. 2)), which meets the national cotton variety approval standard and has been approved. It belongs to the first generation of mid-mature hybrid with insect-resistant gene, which is suitable for spring sowing in the cotton areas of the Yellow River valley in southern and central Hebei, Shandong, northern and central Henan, Jiangsu and Anhui to the north of the Huaihe River. it should be promoted strictly in accordance with the scope allowed by the safety certificate of agricultural genetically modified organisms.
