库尔干农学院作物栽培教研室研究了播种材料质量鉴定的各种方法,这些方法能预测种子的田间发芽率。试验既用了标准指标(发芽势、实验室发芽率),也采用了现代化指标。为了测定幼芽的穿透能力,在持水量达60%的湿润沙土的种子发芽器内,播种春小麦品种“洛伐斯布尔史卡亚67”Новосибрская 67)的种子,并在上面盖上每层厚度为1厘米的聚氨脂纤维10层。把盛着种子的8个种子发芽器构成一组,摆放在恒温器内。在20℃的温度下,到第十天统计每层聚氨脂纤维上的幼芽数量,根据幼芽数来确定出种子出苗率的指标,这个指标要适合于种子盖土的一定深度。质量不同的种子,受到不同物理因素的影响,
The Department of Crop Cultivation at Kurgan Agricultural College has studied various methods of quality identification of sowing materials and these methods can predict the germination rate of seeds in the field. The test used both standard indicators (germination potential, laboratory germination rate), but also the use of modern indicators. In order to determine the penetration ability of sprouts, the seeds of a spring wheat cultivar “Schalkar 67” “Новосибрская 67” were seeded and covered on top in a germinator of moist soil with a water holding capacity of 60% 10 layers of polyurethane fiber each 1 cm thick. A group of 8 seed germinated seeds are placed in the thermostat. At the temperature of 20 ℃, the number of sprouts on each layer of polyurethane fiber was counted on the tenth day. According to the number of sprouts, the index of seed germination rate was determined. This index should be suitable for the depth of seed cover soil. Different quality seeds, subject to different physical factors,
