红豆草和紫花苜蓿在同仁县生产性状的初步比较结果

RESULT ON PRODUCE PREPERTIES OF PRIMARY COMPARE WITH SAINFOIN AND ALFALFA IN TONGREN AREA

试验结果表明 ,在同仁县的隆务河谷地区有灌溉的条件下 ,红豆草在种植前两年的生长速度和产草、产籽量均明显高于紫花苜蓿。红豆草在种植当年就可以收到部分成熟种子 ,如果收草用 ,当年可刈割两茬 ,但越冬率较苜蓿差 ,第 2年可刈割三茬 ,每公顷产鲜草 962 82kg/hm2 ,产种子 1 1 35.5kg/hm2 。紫花苜蓿产鲜草 731 97kg/hm2 ,产种子 1 99.5kg/hm2 。红豆草较紫花苜蓿更适合于隆务河谷较阴湿的荒山荒坡 ,房前屋后及田埂地头上种植 。

Test result indicated that sainfoin compare with alfalfa. Sainfoin have clear superiority in grow speed, produce yield of grass or seed in planting two years, which have irrigation on river valley of Tongren, Longwu area. Sainfoin could gain some mature seeds in the planting year and cut grass twice in the year, twice in the next year. Its grass yield was 6418.8kg/ha, seed yield was 75.7kg/ha. Alfalfa yield was 4879.8kg/ha, seed yield was 75.7kg/ha; alfalfa yield was 4879.8kg/ha, seed yield was 13.3kg/ha, planting sainfoin was fitter than alfalfa in wasteland and ridge.
