摘　　要：上杭县果树种植面积6666.67 hm^(2)以上,且以丘陵山地为主,土壤普遍瘠薄,培肥果园地力对提高果品产量和品质尤为重要。为丰富山地果园绿肥品种,特进行紫花苕子引种试验。结果表明:紫花苕子在上杭县山地种植表现为生长适应性较强,综合生物学性状良好,具有较强的耐寒性、耐瘠性;11月至次年1月均可播种,播种量以60.0 kg/hm^(2)为宜,果园春季至7月底均无需除草,抑草保墒效果好;盛花期鲜草产量在27 t/hm^(2)以上,培肥地力效果较好。The planting area of fruit trees in Shanghang County is over 6666.67 hm^(2),mainly in hilly and mountainous areas.The soil is generally barren,and fertilizing the orchard soil is particularly important for improving fruit yield and quality.In order to enrich the variety of green manure in mountain orchards,a introduction experiment of Vicia sativa subsp.nigra was conducted.The results showed that Vicia sativa subsp.nigra showed strong growth adaptability,good comprehensive biological characteristics and strong cold and barren resistance when it was planted in the mountainous areas of Shanghang County.Seeding could be carried out from November to January of next year,the appropriate sowing rate was 60.0 kg/hm^(2),which could maintain the orchard without the need for weed control from spring to the end of July.The effect of grass suppression and soil moisture preservation was good.During the peak flowering period,the fresh grass yield was above 27 t/hm^(2),and the effect of fertilizing soil was good.
