1973年我盟引进一年生白花草木樨种子约1斤,经连年多点繁育试种,现已在全盟推广,去年种植面积约2,000多亩。各地种植证明,这种绿肥作物,枝叶繁茂,适应性强,具有抗旱、抗寒、耐盐、耐瘠薄等优点,是一种速生高产、改土肥田的优良绿肥,也是牲畜的优良牧草。在农牧区推广种植,对于解决地缺肥、畜缺草有很大的现实意义。一、生物学特性根据河北农业大学系醒东教授的研究,认为一年生白花草木樨(Melilotus alba var.annuaCoe.)是由二年生白花草木樨演变而来,为一年生豆科草本植物,属于草木樨属(Melilatus)。在植物学形态特征上近似于二年生白花草木樨,根系发达,生有很多根瘤。茎直立,高150—230厘米。叶为
In 1973, our union introduced about one kilogram of annual white clover seed, and after several years of breeding, it has been popularized in the League. Last year, the planting area was about 2,000 mu. It is proved that this green manure crop has many advantages such as drought-resistant, cold-resistant, salt-tolerant and barren-resistant. It is an excellent green manure with high yield and soil rejuvenation and good forage for livestock. Promote planting in farming and pastoral areas, to solve the problem of lack of fat, livestock shortage of grass has great practical significance. First, the biological characteristics According to the Department of Wake Professor of Hebei Agricultural University, the study, that annual perennial plants (Melilotus alba var.annuaCoe.) Is a biennial white Herbarium evolved from the annual leguminous herbs, belonging to the genus Apricot Melilatus. In the botanical morphology is similar to biennial white flowers clogs, root system developed, there are many nodules. Stem erect, height 150-230 cm. Leaves for
