棉花花铃期是形成产量的关键时期,由营养生长和生殖生长并进逐渐转向以生殖生长为主,是这一时期棉花生育的主要特点。因此,协调营养生长和生殖生长的矛盾,防止早发棉田早衰,促使迟发棉田早熟,力争在当地最佳生态条件下,使不同生长型的棉花着结较多的优质棉铃,是该阶段田间管理的重心。可见,花铃期管理的成败,对棉花产量的高低和纤维品质的优劣影响极大。现就花铃期管理,择要概述如下。
Cotton flower boll stage is the key period for the formation of yield, from vegetative and reproductive growth and gradually turned to reproductive growth-based, is the main characteristics of the cotton during this period. Therefore, to coordinate the contradiction between vegetative and reproductive growth, to prevent premature aging in early cotton fields and to promote early maturity in late cotton fields, and to strive to bring more cotton bolls with different growth types under the best local ecological conditions, The center of management. Can be seen that the success or failure of flower and boll management, the level of cotton production and fiber quality has a great influence on the merits. Now spend the bell management, choose to be summarized as follows.
