为了搞好棉花良种提纯复壮,就必须根据棉花品种的特征、特性进行单株选种,做好标记,单株分收,室内考种。根据上述要求,为了得到充分的选择,选择数量常达千株以上,如用布口袋包装,常由于需要量大,很难满足要求。几年来,我们大队农校和农科队利用旧报纸代替种子袋进行单株分收,经过几年的实践证明,对种子的质量、发芽没有影响。具体做法是:在采摘时,一个单株用一张十六开的旧报纸把摘下的棉花放在纸的一头包卷起来,两头再把纸叠好,呈园筒状。回来后再编号、晒干、考种。考种后的种子仍放在原纸内 In order to do a good job of purifying and rejuvenating cotton varieties, it is necessary to select single plants according to the characteristics and characteristics of the cotton varieties, and mark them well. According to the above requirements, in order to be fully selected, the number of choices often reach more than a thousand, such as the use of cloth bags, often due to the large amount of demand, it is difficult to meet the requirements. In recent years, our brigade schools and agricultural teams used old newspapers instead of seed bags for single-crop distribution. After years of practice, it has shown no effect on the quality and germination of the seeds. The specific approach is: In picking, a single plant with a 16 open old newspaper off the cotton on one end of the paper wrapped up, the two ends of the paper stack well, was cylindrical. Back again after the number, dried, test species. Seed after test seed is still placed in the base paper
