红豆草是一种抗旱、耐寒的优良牧草。近几年在科研、生产上再度引起重视,在我国北方种植面积日益扩大,对干旱、半干旱地区的农业生产起了良好的作用。但目前关于红豆草的栽培技术对其越冬影响的报导尚少。而红豆草能否越冬则是草,籽产量的关键。为使红豆草安全越冬,1985年春对大田和试区的红豆草进行了田间试验和调查。 Soybean is a good drought resistance, hardy forage. In recent years, scientific research and production have drawn great attention once again. The growing area in northern China has played a good role in agricultural production in arid and semi-arid areas. However, there are few reports on the effect of cultivation of sainfoin on the overwintering. The overwinter of sainfoin grass, seed production is the key. In order to ensure safe winter overwintering, field experiments and investigations were conducted on the field and field sainfoin in the spring of 1985.
