棉花是我市主要经济作物,90年以前,由于耕作粗放,管理水平低下,亩产皮棉在80公斤左右徘徊,且品质也较差。近年来我们围绕生产中存在的问题,积极开展了棉花高产栽培技术研究,总结出了一套适合我市目前土肥条件下,亩产皮棉100公斤高产栽培技术。 一、精细整地,蓄水保墒棉花是深根作物,需要土层深厚,质地疏松,透水性好的肥沃土壤,安根水后适时整平土地,翻透四埂四角,拾净前作茬,糖,耙压各三次,达到上虚下实,这样既可提墒保墒、又有利于一播全苗。 二、选用良种,化学除草 Cotton is the main cash crop in our city. 90 years ago, due to extensive farming and poor management level, cotton lint per mu hovered around 80 kg and its quality was also poor. In recent years, we focus on the problems in production, and actively carry out the study of high-yielding cotton cultivation techniques, summed up a set of suitable for the current city of soil and fertilizer conditions, 100 kg per mu lint yield cultivation techniques. First, the fine preparation of land, water and moisture Cotton is a deep root crop, need deep soil, loose texture, good permeability of the fertile soil, root water after leveling the land at a suitable time, through the four corners of the square, picking up the crop before the crop, sugar , Rake pressure three times, to achieve the virtual reality, so that moisture can be added moisture, but also conducive to a broadcast seedlings. Second, the selection of seeds, chemical weeding
