春季是多种牧草播种的主要季节,如果播种了发芽力较低的种子,必然是出苗不齐,田间缺苗,尤其是多年生牧草,一旦田间出苗率低,对第一年青草产量影响很大。因此,在播种之前,必须做好发芽试验。这是决定种子品质好坏,能否播种和决定播种量的重要依据。一、牧草种子发芽需要哪些外界条件种子发芽必须的条件是水分、温度、氧气和光线。做发芽试验,首先要满足这些条件,给它创造适当的发芽环境,才能得到准确的试验结果。 Spring is the main season for planting a variety of herbage. If sowing seeds with low germination power, it will inevitably be sprouting, field lack of seedlings, especially perennial herbage. Once the rate of emergence in the field is low, it will have a great impact on the first year’s grass yield . Therefore, germination tests must be done before sowing. This is an important basis for determining the quality of the seeds, sowing and determining the sowing rate. First, the forage seed germination which external conditions need to germinate germination must be the conditions of moisture, temperature, oxygen and light. Do germination tests, first of all to meet these conditions, give it to create a suitable germination environment, in order to get accurate test results.
