一、大田条件下5904—И及胜利一号经济性状的一般表现农一师塔里木河灌区各农场自1959年开始大面积种植细绒棉以来,历年面积、总产量及单位面积产量都是稳定提高,说明目前所采用的品种和栽培技术措施基本上是适当的.但最近生产的原棉质量有退化变劣趋势,不能满足特纺工业的要求,售价也有所降低,影响农场经济收入.为了摸清情况探索原因,提供选择品种、制定栽培技术措施,以解决早熟、丰产、优质问题,我们于1961年对该区推广的细绒棉品种5904—И和胜利一号,进行了在大田条件
I. General Performance of 5904-И and Victory-1 Economic Performances under Field Conditions Since the farm of Tarim River Irrigation District of Nongyi Division started planting large-area fine cottons in large area since 1959, the annual output, total output and yield per unit area have steadily increased , Indicating that currently used varieties and cultivation techniques are basically appropriate measures.But the recent production of raw cotton quality degradation trend, can not meet the requirements of special spinning industry, the price has also decreased, affecting the farm economic income.In order to touch Qing conditions to explore the reasons for providing choice of species, cultivation techniques to develop measures to solve the problem of early maturity, high yield, high quality, we in 1961 to promote the area of fine cotton varieties 5904-И and Victory No. 1, carried out in the field conditions
