紫花苜蓿为豆科作物苜蓿属,多年生草本植物。它的根系发达入土深,抗寒、抗旱能力强,喜中性或微碱性土壤生长。紫花苜蓿含营养丰富,含蛋白质高,适口性好,被称为各类家畜喜食的“饲草之王”,在当地大面积种植成本低、用水少,产量高,效益好。苜蓿一年刈割2—3次,亩收鲜草高达万斤以上,折合干草1500公斤以上。为解决苜蓿当年种植收入少的问题,我们实行套种,这样既利于来年高产,又有当年的好收成,现将栽培技术介绍如下: Alfalfa is a leguminous crop of Medicago, a perennial herbaceous plant. Its roots developed deep into the soil, cold, drought ability, like neutral or slightly alkaline soil growth. Alfalfa contains nutrient-rich, high protein, palatability, known as the “forage king” of all kinds of livestock, large-scale planting in the local low cost, less water, high yield, good efficiency. Mowing alfalfa 2-3 times a year, acres of fresh grass up to ten thousand pounds, equivalent to more than 1,500 kg hay. In order to solve the problem of less planting income of alfalfa in the current year, we implemented intercropping so as to benefit both the high yield in the coming year and the good harvest in that year. Now we introduce the cultivation techniques as follows:
