幼龄荔枝园间作热带豆科牧草试验初报

通过在荔枝Litchi chinensis园中间作8个不同豆科牧草品种的3年试验,结果表明:82号柱花草Stylosanthes guianensis cv.GC1480间作鲜草平均产量居最高,达到15 400 kg/hm2;平托落花生Arachis pintol对荔枝的茎围增长促进作用最强,达到11.0 cm,82号柱花草达到了10.7 cm,这些豆科牧草间作对荔枝茎围影响差别不显著;对荔枝冠幅的影响存在显著性差异,有钩柱花草S.hamata cv.Verano冠幅达到5.866 7 m2,其次为爪哇葛藤Pueraria phaseoloides,达到5.733 3 m2;对荔枝花梢影响与55号柱花草S.guianensiscv.CIAT1044呈极显著差异,82号柱花草达到34.6簇,其次是爪哇葛藤,达到30.5簇,均优于55号柱花草.

A Study of Leguminous forage Intercropped in young Litchi orchard

Eight species of leguminous forage were tested intercropped in young Litchi orchard about 3 years in this trial,the result showed that fresh forage yield of Stylosanthes guianensis cv.GC1480 was the highest reaching 15 400 kg/hm~2;There was no significant differences among these legumemous,Arachis pintoil was the best benefit to addition of L.stem reaching 11.0 cm and S.guianensis cv.GC1480 was the second best reaching 10.7 cm;There lied prominent different impact on crown of Litchi tree,S.hamata cv.verano was the biggest to 5.866 7 m~2 and Pueraria phaseoloides was 5.733 3 m~2;There was most prominent difference in quantity of Litchi flower among these leguminous treatments,the quantity of S.guianensis cv.GC1480 flower were about 34.6 bundles and Pueraria phaseoloides were about 30.5 bundles,both were better than S.guianensis cv.CIAT1044.
