Detailed Product Description

High yield hybrid Cotton seeds

Characteristics
This varity as the mature, insect-resistant hybrid cotton varieties, cotton for the Yangtze River Valley cotton planting in spring, about 130 days growth period. Strong growth potential, early growth and stability, rapid growth during the blooming period, drought and strong, enough stamina. Plant was the tower type, height 120 cm, hard stems, the number of fruit branches per plant is about 18 units. Leaves of medium size, level of clear air and light, good boll is strong, bell large (more than 6 grams boll weight), boll opening smooth, about 40% of lint percentage, fiber quality, cotton lint, good color, with silk. The average length of 30.3 mm fiber HVICC, strength 34.3 cm / Turks, 4.6 micronaire, uniformity index of 85.2%, 7.1% elongation, 77% reflectance, yellowness 8.1, spinning evenness index 158, appropriate 60 high-quality cotton yarn spinning. Resistance to Fusarium wilt, Verticillium wilt resistance and high resistance to bollworm and pink bollworm, comprehensive quality traits, high yield performance, generally 600 pounds or so of seed cotton per mu, high terraces up to 800 pounds or more.
Third, the cultivation techniques
1, the proper sowing. SSowing Water the seedbed to dry seed sowing a bowl of grain, mulch 1 ~ 1.5cm,full stand ventilation time after the lower humidity, weed control, disease prevention, nurturing seedlings.
2, rational close planting. Suza 3, strong growth potential, appropriate Sparse, create a good high-yield group. Plain spaced 1.1 ~ 1.2m, planting density is generally in the 1200 ~ 1400 / mu, up to over 1500; hilly area of about 1.0m spacing, density control in the 1500 ~ 1600 / mu, not more than 1,800 / mu.
3, scientific fertilization. Requirements of basal feet, Miaofei light, steady fat bud, flowering and boll weight applied fertilizer, cover top of applied fertilizer. Medium fertility plots, basal urea 20kg, P 30 ~ 40kg, potassium chloride 7.5kg / mu, with water after transplanting urea Mushi 10kg, Lei fertilizer in June 15 ~ 20, applied potassium chloride 15kg / mus, fertilizer boll of cotton in mid-July on the base Results from 1 to 2 large bell to live when the urea 30kg / mu, potassium chloride 10kg / mu, usually in the beginning of autumn roof after fertilizer urea 10kg / mu.
4, moderate chemical control. Master before the light, the comfortable, after heavy, a small amount, the use of the principles, general bud each DPC amount of 2 g / mu, early flowering 3 g / mu, flowering after topping a week or 4 g / mu the specific amount should be based on cotton growing and the climate was established, growth vigor, rain should be an appropriate dosage, growth, dry weather, when not busy or reduction may be appropriate to create a better plant type.

6, the timely pest control. Seedling bud stage focus aphids, red spider bugs Xiang and control, spider mite do a good job in the late primary, prevention and treatment of Spodoptera litura; third and fourth generation cotton bollworm, pink bollworm, such as base, to achieve control targets, also drug prevention.
In short the use of cultivation practices with the local organic cultivation techniques and habits combine the sky, look at the growth of the seedlings flexibility. The general principle is to promote nurturing seedlings seedlings to early onset; bud stage, the early flowering stage hold on long, setting up the yield shelves; Potassium fertilizer flowering more than enough bolls, late Paul stability against premature aging.
