福建省典型双季稻区适宜紫云英品种比较试验

在福建闽北山丘盆地（浦城县）、闽西低山丘陵（连城县）、闽东滨海平原（福鼎市）3个典型双季稻区开展适宜紫云英品种比较试验。结果表明，不同稻作区闽紫5号和余江大叶生育期均表现较皖江大叶青和弋江种长。同一试验点紫云英品种鲜草产量存在差异，在浦城以闽紫5号最高，达41.68t/hm2；连城以余江大叶最高，达28.82t/hm2；福鼎以皖江大叶青最高，达29.85t/hm2；同试验点紫云英品种植株养分含量存在差异。综合考虑紫云英生长性状、鲜草产量及植株养分含量等因素，闽北山丘盆地、闽西低山丘陵双季稻区适宜的紫云英品种为闽紫5号和余江大叶，闽东滨海平原双季稻区适宜的紫云英品种为闽紫5号和皖江大叶青。

Comparison Experiment of Astragalus Sinicus Varieties in Typical Cropping Area of Fujian Prov-ince

The comparison experiment of suiting for Chinese milk vetch（Astragalus sinicus）were tested that basin in northern of Fujian Province hill（Pucheng County）,western of low hills（Liancheng County）,the east-ern of coastal plain of（Fuding County）three typical cropping area.The results showed that in different rice regions Minzi No.5 and Yujiangdaye were superior to Wanjiangdayeqing and Yijiang in growth period.In the same test point Chinese milk vetch（Astragalus sinicus）varieties were different between in grass yield, Minzi No.5 in Pucheng County was highest,up to 41.68t/hm2;Yujiangdaye in Liancheng County was highest, upto 28.82t/hm2;Wanjiangdayeqing in Fuding County was highest,up to 29.85t/hm2;In the same test point with Chinese milk vetch（Astragalus sinicus）varieties were different between plant nutrient content.Consider-ing Chinese milk vetch（Astragalus sinicus）growth characteristics,grass yield and plant nutrient content and other factors,basin in northern of Fujian Province hill,western of of Fujian Province low hills cropping ar-ea suitable for Chinese milk vetch（Astragalus sinicus）varieties with Minzi No.5 and Yujiangdaye,the east-ern of coastal of Fujian Provinc plain cropping area suitable for Chinese milk vetch（Astragalus sinicus）vari-eties with Minzi No.5 and Wanjiangdayeqing.
