十六个紫花苜蓿品种在新疆巴里坤县越冬性研究
|
摘要
通过2016-2017年在新疆巴里坤县对国内外16个紫花苜蓿品种进行比较试验,结果表明:种植第一年均能完成从出苗到分支的生育过程,由于品种的差异导致各个生育期时间有所不同;在冬季常规的自然环境条件下(冬灌覆雪和不冬灌覆雪),标靶、冰驰、和田大叶和阿尔冈金等四个紫花苜蓿品种越冬率89.65%~98.53%,是最适宜当地气候的紫花苜蓿品种,在有冬灌条件的地方,岩石(97.65%)、DS310FY(98.45%)和勇士(98.96%)也可作为候选补充品种;在第一年冬季进行科学田间管理(冬灌和覆雪)可有效地保护和提高紫花苜蓿越冬率。
A comparative experiment of 16 alfalfa varieties was carried out in Barkol County in 2016-2017.The results showed that the growth process from emerging to branching could be completed in the first yea. As a result of different varieties, each growth period is different from each others. Under the normal natural environment conditions in winter(with or without winter irrigation and snow covering), the winter overwinterring rate of four species of Medicago sativa, such as Target, Ice Chi, Hetian Large Leaf and Algonquin, is 89.65%~98.53%, which are the most suitable alfalfa varieties for local climate. Where there are winter irrigation conditions, the Rock(97.65%) DS310 FYN(98.45%) and Warrior(98.96%) could also be selected as the candidates. The survive rate of Medicago sativa could be protected and improved by field management(winter irrigation and snow covering) in the first winter.
