推广棉花优良品种或在棉花播种前,推行棉籽发芽试验,是提高种籽纯度、确定播种量、保证全苗的主要关键之一。兹将发芽试验中应注意事项及进行程序略谈如下:一、发芽试验中注意事项:(一)试验室温度的控制:试验室温度的高低、关系着发芽率和发芽势都很大。据我们的经验,发芽试验室的温度,最好从开始试验时就保持在摄氏30—35度之间,这样能集中发芽,并节省时间和煤火。但要注 Cotton varieties to promote good or cotton sowing before the implementation of cottonseed sprouting test is to improve the purity of the seed to determine the sowing rate, one of the key to ensure the whole seedlings. Will germination test considerations and procedures are as follows: First, the germination test Notes: (A) control of laboratory temperature: the level of laboratory temperature, the relationship between the germination rate and germination potential are great. In our experience, germination laboratory temperature, the best from the beginning of the test to maintain at between 30-35 degrees Celsius, which can focus on germination and save time and coal fire. But to note
