Growing Techniques 0 views
Characteristics: The growth period is 129 days, belonging to a medium-early maturing upland cotton variety. Plant height is 90.7 cm, the fruit branch node position is around 6.4, the plant is tower-shaped with good light penetration, strong boll-setting ability, relatively abundant stem and leaf trichomes, medium-sized leaves with relatively deep notches, lighter green leaf color, oval bolls, smooth and concentrated boll opening, single boll weight 5.7 g, seed index 10.8 g. Cultivation techniques: Increase basal fertilizer application, apply flower and boll fertilizer early and heavily, and supplement with top-dressing fertilizer. Flower and boll fertilizer should be applied heavily ahead of schedule at the early flowering stage, generally top-dressing 15-20 kg of urea per mu in early July. Around July 25

Cultivation techniques: Increase basal fertilizer application, apply flower and boll fertilizer early and heavily, and supplement with top-dressing fertilizer. Flower and boll fertilizer should be applied heavily ahead of schedule at the early flowering stage, generally top-dressing 15-20 kg of urea per mu in early July. Around July 25, supplement with top-dressing fertilizer, applying 5-7.5 kg of urea per mu. During the entire growth period, irrigate promptly when drought occurs, until mid-September. In the later stage, spray foliar fertilizer; generally starting in early August, spray 2% urea solution on cotton fields showing nutrient deficiency, spraying once every 7-10 days for three consecutive sprays.

Pest and disease control: Promptly control non-lepidopteran pests such as cotton aphids and mirid bugs.
