温室种植不同苜蓿品种比较试验

Comparative Test on Different Alfalfa Cultivars Planted in Greenhouse

为了了解温室种植苜蓿的生产性能,对6个苜蓿品种进行了比较试验。结果表明,6个苜蓿品种中,WL323苜蓿的干草总产量最高,为18 758.33 kg/hm2;阿尔冈金苜蓿的平均生长速度明显高于其他品种,可达1.44 cm/d;阿尔冈金苜蓿在留茬高度为5 cm时的茎叶比最高,为0.873 2;抗蓟马苜蓿在留茬高度为5 cm时的鲜干比最高,为12.846 5;苜蓿王的粗蛋白含量最高,为21.98%。

In order to understand the production performance of alfalfa cultivars planted in greenhouse, the comparative test on six alfalfa cultivars was made . The results showed that the total hay yield of WL323 alfalfa cultivar was the highest , reaching 18 758.33 kg/hm2. The average regeneration speed of Algonquin alfalfa cultivar was 1.44 cm/d, which was obviously higher than other cultivars. The stem-leaf ratio of cultivar Algonquin with the stubble height of 5 cm was the highest, reaching 0.873 2. The fresh grass-hay ratio of Anti-thrips alfalfa with the stubble height of 5 cm was the highest, reaching 12.846 5. The crude protein content in Alfaking was the highest, being 21.98%.
