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。
The Kashgar region of Xinjiang belongs to the arid region, with serious soil salinization, accounting for about 47% of the existing cultivated land area. The shortage of forage material has become an important factor restricting the development of animal husbandry. In recent years, Kashgar region has further increased forage planting efforts, especially the cultivation of high-quality forage alfalfa, about 7 790 hm2 per year. Due to the different adaptability of different varieties, the yields are quite different. In order to select the high-quality and high-yield alfalfa varieties with drought and salinity resistance, six drought-resistant cultivars including root tiller type, 3010, Algonquin, Golden Queen, Giant and Reindeer Salt-tolerant alfalfa varieties, the introduction of the test. Through two years of plantation management and observation record analysis, the results showed that root and shoot type, 3010, Algonquin, Golden Queen alfalfa can be suitable for my district p H value of 6.5 to 9.0, soluble salt below 0.6% Degree and below) to promote soil cultivation.
