棉苗出土后,棉田管理的中心任务应该是保证全苗、培养壮苗和促进幼苗的生长发育。棉田不缺苗,是棉花丰产的一个基本条件。培养壮苗,提早幼苗的生长发育期,可以使棉花整个生育期提早,增加霜前花,提高棉花品质,增加单位面积的总产量。在棉花的棉期管理上,过去一般是缺株现象普遍;间苗定苗不适时;早期中耕不够;正枝去油条工作拖迟:以及对肥、水的供应不当等,因此,棉花丰产潜力尚未充分发挥。为了争取1959年更大丰收。完成全
After the emergence of cotton seedlings, the central task of cotton field management should be to ensure that the whole seedlings, seedlings and training to promote the growth and development of seedlings. Cotton field no shortage of seedlings, is a basic condition of cotton yield. Cultivate strong seedlings, early seedling growth and development period, you can make the cotton earlier growth period, increase frost before the flower, improve cotton quality, increase the total yield per unit area. In the management of cotton in cotton, the past is generally a phenomenon of lack of strains; the lack of seedlings Miao Miao; early cultivation is not enough; Zhengzhi to the fritters delay: and the improper supply of fertilizer, water, etc. Therefore, the cotton yield potential has not yet fully demonstrated . In 1959 for greater harvest. Complete the whole
