一、生育特点:棉花进入吐絮期后,营养生长和生殖生长都逐渐减退,根系吸收能力减弱,干物质积累减少。吐絮初期,伏桃逐渐成熟,秋桃正在长大。此期较高的温度、充足的日照和较低的湿度可以加速碳水化合物的转化,促使脂肪和纤维素形成,并加速铃壳开裂和吐絮。此期管理对提高产量和品质仍十分重要。二、田间诊断:高产棉田吐絮的长势长相:从个体发育情况看,顶部果枝平伸,果枝
First, the reproductive characteristics: cotton boll flowering period, the vegetative and reproductive growth are gradually diminished, the weakened absorption capacity of the roots, dry matter accumulation decreased. Noctilucent early vubaura gradually mature, autumn peach is growing up. Higher temperatures, adequate sunshine and lower humidity during this period can accelerate the conversion of carbohydrates, promote the formation of fats and cellulose, and accelerate the cracking and bolting of bell peppers. The management of this period is still very important for improving production and quality. Second, the field diagnosis: high-yielding cotton boll floc growth looks: from the individual development situation, the top of the fruiting branches flat, fruiting branches
