高温胁迫下不同黑麦草产量和品质的差异研究(9500字)
摘 要: 本试验大量引进各地的优势黑麦草品种,在大田中进行试验,用统计黑麦草鲜重、风干重的方法能很直观的筛选出产量高的牧用型黑麦草品种,在黑麦草耐热品质的方面,测定其生理生化指标,筛选出对高温抗性优良的草坪型黑麦草品种。 结果表明在试验组的12个黑麦草品种中:沃土、俄勒冈四倍体、抗锈王、麦迪的产量比较高,是我们筛选出的产量高的牧用型品种;首相在各方面的耐热性比其它品种明显要强,是我们筛选出的抗性强的草坪型品种。

The study of the production and quality of different ryegrass under high temperature stress
Abstract: In this study a large number of advantages over the introduction of ryegrass varieties in the field in the experiment. In this study, a statistical ryegrass fresh weight, dry weight method can filter out very intuitive to use, animal husbandry, high yield type ryegrass varieties, the quality of the heat-resistant ryegrass, the determination of the physiological and biochemical indexes were selected for resistance to high temperature Excellent varieties of turf-type ryegrass. The results showed that the experimental group of 12 ryegrass varieties: fertile, tetraploid Oregon, anti-rust Wang, Tracy McGrady of the relatively high yield, we screened the pastoral use of high yield varieties; Prime Minister in all aspects of the resistance heat significantly stronger than the other varieties, we selected a strong resistance to turf-type varieties.
