Fiber quality: According to the test results of the Cotton Quality Supervision, Inspection and Testing Center of the Ministry of Agriculture in 2004, the average upper half mean length was 28.9mm, the uniformity index was 84.9, the specific strength was 30.3cN/tex, the elongation rate was 6.9%, the micronaire value was 4.6, the reflectance was 74.5, the yellowness was 8.1, and the spinning consistency index was 142. Yield performance: According to the regional trial results of the spring-sown conventional cotton group in Hebei Province from 2003 to 2004, the average lint yield per mu was 96.1kg and 94.3kg respectively, and the pre-frost lint yield was 9

Yield performance: According to the regional trial results of the spring-sown conventional cotton group in Hebei Province from 2003 to 2004, the average lint yield per mu was 96.1kg and 94.3kg respectively, and the pre-frost lint yield was 91.6kg and 86.1kg respectively. According to the production trial results of the same group in 2004, the average lint yield per mu was 87.4kg, and the pre-frost lint yield per mu was 80.8kg.

Key points of cultivation techniques: Sowing time: April 15-25 for plastic-film mulched cotton fields, and April 25-30 for bare fields. Planting density: 1500-2300 plants/mu for high water and fertility plots, 2300-3300 plants/mu for medium fertility plots, and about 4000 plants/mu for dry and barren land. Apply sufficient base fertilizer, increase potassium fertilizer, topdress and irrigate in time before the initial flowering stage, apply heavy flower and boll fertilizer, irrigate sufficiently at the full flowering stage, and appropriately topdress with a topping fertilizer. Control cotton field pests in time.
