新疆喀什地区抗旱耐盐碱紫花苜蓿新品种引种试验

新疆喀什地区属于干旱地区,土壤盐碱化严重,约占现有耕地面积的47%,且饲草料的短缺成为制约畜牧业发展的重要因素。近年来,喀什地区进一步加大了饲草料种植力度,特别是优质饲草紫花苜蓿的种植,每年约7 790 hm2。因各品种适应性不同,产量差异较大,为了选出抗旱耐盐碱的优质高产紫花苜蓿品种,专门从国外引进了根蘖型、3010、阿尔冈金、金皇后、巨人和驯鹿六个抗旱耐盐碱的苜蓿品种,进行引种试验。通过两年的种植管理和观测记录分析,结果表明根蘖型、3010、阿尔冈金、金皇后苜蓿能够适合我区平原区p H值在6.5~9.0之间,可溶性盐分在0.6%以下(中度及以下)的土壤种植推广。

Experiment on Introduction of New Varieties of Salt- and Drought-resistant Alfalfa in Kashi

Kashi is an arid region, and the soil salinization is serious, which take up about 47% of the existing arable land, moreover,, the shortage of forage has become a key factor restricting the development of animal husbandry. In recent years, Kashi further increases the cultivation of forage, especially alfalfa with high quality that is cultivated about 7 790 hm2 per year. However, the yield of various varieties differs greatly due to their different adaptation. To identify the salt-and drought-resistant Alfalfa with high quality and high yield, we introduced six varieties from abroad to test, including Medicago Varia, 3010, Algonquin, Golden Queen, Giants and Reindeer. With the cultivation, observation, record and analysis for two years, it is indicated that Medicago Varia, 3010, Algonquin and Golden Queen could adapt to the soil in plain region in Kashi (the soil pH value is 6.5~9.0, and soluble salt is lower than 0.6%) .
