棉花是我区的主要经济作物。为了提高棉花产量,1973年我们进行了用硼砂溶液处理棉种的试验,以探讨硼元素对棉花生长发育和产量的影响。 一、试验方法 试验在盆栽条件下进行,设硼砂溶液浸种和白水浸种两个处理,重复6次,供试品种为鄂光棉。播种前将种子分别放在0.01%硼砂溶液中和白水中浸种24小时,然后催芽播种。每盆播3粒,齐苗后定苗留一株,行距50厘米,株距35厘米。管理上除不进行整枝打顶外,治虫、施肥、灌水等项措施,均严格按照等量一致的要求进行。 二、试验结果
Cotton is the main cash crop in our district. In order to improve the cotton yield, we carried out the experiment of treating the cotton seed with borax solution in 1973 to study the influence of boron on the cotton growth and yield. First, the test method The experiment was carried out under potted conditions, set bismuth solution soaking and white water soaking two treatments, repeated 6 times for the test varieties E cotton. Seed before sowing in 0.01% borax solution and soaking in white water for 24 hours, then germination sowing. Each pot sowing 3, Qi Miao after Dingmiao stay a line spacing of 50 cm, spacing 35 cm. In addition to the management of pruning topping, the worm, fertilization, irrigation and other measures are in strict accordance with the same amount of consistent requirements. Second, the test results
