抓紧抓好棉田的冬季深耕翻土,是套作棉区夺取棉花高产的基本环节之一,稻茬棉田尤为重要。套作棉区,一般复种指数较高。稻茬麦套种棉田,经长期浸水,土壤粘湿僵硬,地温低,通透性差,养分分解慢,种麦前虽经耕翻,但因“三秋”季节紧迫,特别是去年“三秋”多雨、地湿,耕作往往较浅,泥块较粗,甚至还残留一些有害物质;棉花麦套种棉田,则无机会翻耕,土壤结构也较差。这些,都
Pay close attention to the winter cotton plowing, is set for the cotton area to seize the high yield of cotton one of the basic aspects of the rice crop is particularly important cotton fields. Set cotton area, the general multiple crop index higher. Due to long time flooding, the soil is sticky and wet, the ground temperature is low, the permeability is poor, and the nutrients are decomposed slowly. Although the wheat is plowed through the tillage, the season of “Sanqiu” is pressing, especially last year, Moist, tillage tends to be shallow, coarse mud, and even some harmful substances remain; cotton wheat intercropping cotton fields, there is no opportunity to plow, the soil structure is also poor. These, all
