种子发芽试验是农林、园艺和科研生产中极为重要的判断种子质量的一项指标。准确的试验结果,对确定适宜的播种量和保证全苗,有重要的现实意义,亦是目前我们国家种质库衡量各类作物入库种子质量的主要指标之一。要得到准确的发芽试验结果,就要满足种子发芽的基本条件:水、气、温。在温度能满足的条件下,发芽床是关键,发芽床把水、气于一体。《国际种子检验规程》中规定的发芽床有纸床:纸上(TP),纸间(BP),褶裥纸(PP);砂床:砂上(TS),砂中(S)。我们种质库每年要做成上千万份种子的发芽试验,包括各种作物,各种粒型的种子,任务大,操作人员多。在大批量做大粒型种子发芽时,使用砂床操作很不方便,我们曾用纸上、纸间、蛭石发芽床,各有利弊。据资料介绍,用塑料泡膜做发芽床,泡膜吸水多,可以重复
Seed germination test is an important indicator of seed quality in agriculture, forestry, horticulture and scientific research. Accurate test results have important realistic meanings for determining proper sowing volume and ensuring whole seedlings, and are also one of the main indicators for measuring the quality of seeds deposited by various types of crops in our national germplasm bank. To get accurate germination test results, it is necessary to meet the basic conditions of seed germination: water, gas and temperature. Under the conditions of temperature can be satisfied, germination bed is the key, germination bed water, gas in one. The germination bed provided for in the International Seed Testing Code has paper beds: paper (TP), paper (PP), pleat paper (PP); sand bed: sand (TS), sand (S). Our germplasm bank produces tens of millions of seed germination tests every year, including all kinds of crops and all kinds of grain seeds. The tasks are large and there are many operators. In large quantities of grain seed germination, the use of sand bed operation is very inconvenient, we have used paper, paper, vermiculite germination bed, each has its own advantages and disadvantages. According to the introduction of the material, the germination bed made of plastic bubble film, the bubble film absorbs much water and can be repeated
