抗病洞庭棉在射洪的气候土壤条件下,苗、蕾期生长势较旺,与洞庭一号比,出苗提前1—2天,真叶期提前2—3天,苗子比其它品种高一寸左右。若遇前期雨水充足,施肥偏重,极易造成徒长。盛花阶段若遇干旱,施肥不足,也易早衰。根据这些特点,在栽培技术上要特别注意掌握“稳”和“促”两个技术关键。“稳”就是现蕾至初花阶段,棉株生长发育最旺盛,易徒长,要控制棉株的自然生长发育速度,抓住棉株既要早发,又要稳长,才能培植成矮壮株型,为中、后期开花结铃创造良好条件;“促”,就是棉株在盛花阶段,需水需肥量大,要大水大肥,勤施饱灌,猛攻三桃,做到带桃入伏,伏桃满腰,秋
Resistance to disease cave cotton in the flood conditions and soil conditions, seedling, bud growth vigorously, with the Dongting No. 1, 1-2 days in advance of emergence, true leaf stage 2-3 days earlier, the seedling is about one inch higher than other varieties . In case of pre-adequate rainfall, fertilizer emphasis, can easily result in leggy. Blooming stage in case of drought, inadequate fertilization, but also prone to premature aging. According to these characteristics, special attention should be paid in cultivation techniques to master the “steady” and “promote” the two key technologies. “Stable” is the stage from budding to early flowering. Cotton plants have the strongest growth and development and are easy to grow. To control the natural growth and development of cotton plants, it is necessary to seize the cotton plants to grow early, Plant type, for the middle and late flowering bell to create good conditions; “promote” that cotton plant is in the flowering stage, water needs large amount of fertilizer, water and fat, Qin Shi three irrigation, Meng attack three peaches, so with Peach into volts, volleyball full waist, autumn
