Xinhai No. 42 (the original code tower 07-152) is Xinjiang Tahe seed industry R & D center using high resistance to Fusarium wilt resistant source material as female parent, and has strong boll, quality of lines as male parent and disease resistance, early maturity, high yield cotton new lines. 2013 approved by the the Xinjiang Uygur Autonomous Region crop variety Approval Committee named.
First, the characteristics of the characteristics
The growth period of this species is about 140 days, plant type tube type, more compact, height of 120 cm, stem thick, corolla yellow; zero branches. Cotyledon kidney type, light leaf color, leaf split 5 pieces, a deep, leaf size, leaf color dark green leaves, less hair. In the bell type, there was a clear oil gland point on the bell surface, the bell mouth was pointed, and the bell room was more than 3. Single boll weight 3.40 G. The smooth and concentrated, good picking flowers, color white floc. The strong adaptability, not premature aging, resistance to leaf disease, high resistance to Fusarium wilt, Verticillium wilt resistance. On the early flowering boll, boll, boll opening, Chang Yi picking flowers, good harvest.
Two, production performance
Average results in test in years 2010 and 2011 District: seed cotton and lint, before the frost lint yield respectively for 372.62 kg / mu, mu 122.85kg/, 1.1818 kg / mu, respectively, for control of Xinhai 28 107.64%, 113.11%, 112.66%. Flower before frost was 96.25%, 3.40g 33.02% single boll weight, lint percentage.
Three, fiber quality:
In 2010 and 2011 area test and production test in 2012 in fiber quality average results: HVICC fiber on average half the length 37.3mm fracture than the strength 48.76cN/tex, micronaire value 4.10, elongation at break 4.31%, neat index 88.86%.
Identification of disease resistance by the autonomous region: the disease resistance of the autonomous region in 2012: the disease index of 0.5, high resistance to wilt disease. Verticillium wilt disease index 43.5, resistant to Verticillium wilt.
Four, cultivation techniques:
1 sowing date and sowing density: in mid April, 13000 - 15000 plastic mulching cultivation, seedling plants / mu.
2. The fertilization and irrigation: base fertilizer oil check 80 - 100kg/mu, urea 20kg/mu, three material phosphorus 15kg/mu, under furrow irrigation and fertilization twice, first head of urea 8kg/mu, diammonium 7kg/mu, second second water before urea 10kg/mu. Irrigation 4 times, 8 months late without water, fertilizer, drought and prevent late. Under the condition of drip irrigation, dripping about 10 times, each content in the 20-30 square, topdressing available special fertilizer for drip irrigation, or urea, amount of potassium dihydrogen phosphate, fertilizer with with water application, drip application 6 times, respectively in the early late October, 7 June and mid July and late July, early August, mid August.
3: according to the cotton growth, light adjustment, height control in 110-120cm.
