正确检测判断包衣棉花种子的发芽率,能为种子企业、经营者以及农民提供有力的数据,对农业生产起着积极的指导作用。但由于棉花种子种皮坚硬,其胚又含油性,因此,在做室内发芽试验时,需要打破常规,处理。特别是较敏感的含水量,加水量多少如何准确加水等等笔者通过多年摸索,认为以下处理方法能较准确地反应棉花种子的发芽率。以供同行参考、指导、探讨,共同进步。一、实验材料1.试验用种实验采用同一品种的包衣棉花种子
Correctly detecting and judging the germination rate of the coated cotton seeds can provide strong data for seed enterprises, managers and farmers, and play a positive guiding role in agricultural production. However, due to the hard seed coat of cotton, its embryo is oily, therefore, to do indoor germination test, you need to break the conventional treatment. Especially the more sensitive water content, the amount of water how to add water, etc. How to accurately add water, etc. The author through years of exploration, that the following treatment methods can more accurately reflect the germination rate of cotton seeds. For peer reference, guidance, discussion, and common progress. First, the experimental material 1. Experiment with the kind of experiment using the same variety of coated cotton seeds
