Educator Wang Qinglian Selection Unit Henan Institute of Science and Technology (formerly Henan Vocational and Technical Teachers College) Variety Source Zhongmian 30 Selection Line (Xian) 792 (Xian) Offspring Oriented Breeding Characteristic Characteristics Baimian No. 2 is a high-yield, high-quality, An early-maturity cotton variety suitable for summer sowing and planting disease and insect resistance. The reproductive period is 107~112d. This type of plant is barrel-shaped, moderately elastic, with slightly purple stalks, hairy leaves, moderate leaf size, light green leaves, and strong bell-toting, 9.2 bolls per plant, boll-and-circle, 5.12g bolls, and thin shells. Concentrate on boll opening, with an average of 40.8%. Precociousness, high yield and high yield stability. The pre-frost rate was 88.41%, the average plant height was 76.72cm, the first fruit branch position was 5.47, the average number of fruit branches was 9.95, the finger was 10.16g, and the infertility rate was 7.49%. Fiber quality: 2.5% span length average 27.73 mm, specific strength average 29.27 cN/tex, micronaire average 4.39, spinning uniformity index 131.86. The quality of cotton fiber tested by the Cotton Quality Supervision, Inspection and Testing Center of the Ministry of Agriculture has reached the National Tenth Five-year Breeding Index, which was tested by the Institute of Cotton Research of the Chinese Academy of Agricultural Sciences against disease and insects: Fusarium wilt disease refers to 2.57 and Verticillium wilt disease refers to 37.42. Anti-cotton bollworm. The variety showed early maturation, long-lasting, high-quality, high-yield, strong anti-adversity, good resistance to pests and diseases, and high resistance to Fusarium wilt resistance to Verticillium wilt. It is a good new species with development value. Yield performance is high. Based on the average of 22 sub-regional and production tests for two years, Baimian No. 2 lint and pre-frost lint increased by 25.96% and 31.84%, respectively, compared with the control Zhongmian 30, and the yield increased to a very significant level. In 2002, a regional trial of short-season cotton varieties was conducted in Henan Province. Yields of seed cotton, pre-frost seed cotton, lint cotton, and pre-frost lint were respectively 220.20 kg, 194.89 kg, 91.44 kg, and 81.46 kg, which were higher than the control variety Zhongmian 30 by 24.15. %, 28.9%, 31.38%, and 36.86%; in 2003, the per mu yields of seed cotton, lint, and prefrost lint were 132.40 kg, 51.31 kg, and 38.53 kg, respectively, which increased by 20.65% and 27.99% respectively than the control variety Zhongmian 30. %, 36.64%; The yield per mu of the two-year average seed cotton, lint, and pre-frost lint was 176.30 kg, 71.38 kg, and 60 kg, respectively, which was 22.4%, 29.69%, and 36.75% higher than the control variety Zhongmian 30; In the experiment, the per-mu yields of seed cotton, lint, and pre-frost lint increased by 10.9%, 16.6%, and 18.8%, respectively, compared with the control variety Zhongmian 30, which were 127.6 kg, 50.0 kg, and 43.9 kg, respectively. Cultivation Techniques Points 1 Seeding Period and Density: Two or three types of wheat ridges should be planted in combination with irrigated wheat yellow water, and they should be planted in the wheat ridge between May 20 and around. Wheat can also be harvested before transplanting and wheat transplanted after harvest. Density per acre: 5500-6000 strains of medium fertility cotton field, which can increase or decrease as the soil fertility changes. 2 Fertilization: On the basis of sufficient base fertilizer for the former loquat wheat, apply 5 kg/mu urea at the seedling stage, reapply 15 kg/mu of urea with flower bell fertilizer, and apply potassium dihydrogen phosphate two times at the late stage to prevent premature aging. 3 appropriate control, in order to maintain a steady growth. The review results of the variety review will be reviewed. Baimian No. 2 is in line with the certification criteria for cotton varieties in Henan Province, so it is recommended to participate in the variety review.
