Cotton plants enter the phase of both vegetative and reproductive growth during the bud stage, though vegetative growth still dominates. At this point, the photosynthetic products are mainly directed towards the main stem and fruit branches, which are actively growing, while the buds receive minimal resources. As temperatures rise, the development of roots, stems, leaves, fruit branches, and flower buds accelerates. The plant's metabolism becomes more active, physiological functions are enhanced, and photosynthesis is at its peak. Root growth reaches its most vigorous stage during this time. Effective management during this period focuses on maintaining strong and stable growth, ensuring a solid foundation for future yield.
During the normal budding period, cotton should be "strong but not overgrown, stable but not declining." This means that after developing strong seedlings early on, the plants should grow robustly and remain steady, with strong root systems and healthy buds. The stems should be thick and compact, with red stems making up about 60% of the plant. The plant width should be greater than its height, the top heart should be plump and upright, the leaves should be medium-sized and dark green, and the fruit branches should be strong with many buds. On average, three fruit branches develop every three days. The main stem grows from 0.3 cm per day at the start of budding to 1–1.5 cm, eventually reaching 2–2.5 cm by the end of the bud stage. The height of the first flower cluster is around 50–55 cm, with about 10 fruit branches and over 20 buds.
Proper fertilization and irrigation are essential during this stage. First, steady fertilization is important. The nutrient requirements during the bud stage are higher than in the seedling stage. Fertilizer application should be adjusted based on plant growth, soil fertility, and weather conditions. In fields with rich soil and sufficient base fertilizer, additional nitrogen should be avoided; instead, cake and potash can be applied. Apply 25–30 kg of cake fertilizer and 10–15 kg of potassium fertilizer per acre. For medium-quality fields with good seedlings, 10–15 kg of compound fertilizer containing nitrogen, phosphorus, and potassium per acre is recommended. In poor soil conditions with insufficient base fertilizer and weak seedlings, apply 5–7.5 kg of urea per acre. It’s best to apply fertilizer 30 cm away from the plant to ensure deep placement and coverage, maximizing fertilizer efficiency and avoiding burn damage.
Second, proper watering is crucial. During the bud stage, the soil moisture should be maintained at 10–30 cm depth, with field capacity between 60–70%. When it drops below 50%, immediate watering is necessary to prevent drought stress. To maintain strong and stable growth, avoid flooding and use alternate furrow irrigation, applying 30 cubic meters of water per acre. After watering, cultivate the soil promptly to break up compaction, encourage root development, and improve drought resistance for later stages.
