摘要
为促进当地生态观光农业的可持续发展及贵州观赏绿肥的研究提供参考,采用田间对比试验研究箭筈豌豆不同播种量(T 12 kg/667m^2,T 23 kg/667m^2,T 34 kg/667m^2)对梨园景观化利用效果及其养分积累的影响。结果表明:在盛花期,T 3株高最高,为138.00 cm,T 2根长最长,为18.50 cm,3个处理的株高与根长差异均不显著;T 3的花朵数、花面积及整株鲜草产量最多(高),分别为1525朵/m^2、3001 cm^2/m^2和7022.0 g/m^2,花朵长和宽分别为1.50 cm和1.67 cm;地上部分对N、P和K的积累量分别为473.35 kg/hm^2、31.96 kg/hm^2和272.90 kg/hm^2,均显著高于其余处理;T 2的C积累量为5781.73 kg/hm^2,显著高于T 1,与T 3差异不明显;T 3地下部分对N、P、K及C的积累量分别为17.93 kg/hm^2、1.23 kg/hm^2、12.91 kg/hm^2和3447.94 kg/hm^2,均比其余处理高,差异不显著。箭筈豌豆最佳播种量为4 kg/667m^2时,其在果园绿肥景观化利用中的观赏和利用效果最佳。
In order to provide references for promoting the sustainable development of local ecological sightseeing agriculture and the study of ornamental green manure in Guizhou,a field comparative experiment was conducted to explore the effects of different sowing rates(T 1:2 kg/667m^2,T 2:3 kg/667m^2,T 3:4 kg/667m^2)on landscaping utilization effect in pear orchard and nutrients accumulation of Vicia sativa.Results:In the flowering period,the plant height of T 3 treatment was the greatest,138.00 cm,and the root length of T 2 treatment was the greatest,18.50 cm.The plant height and root length of the three treatments were not significantly different;The number of flowers per square meter,the flower area,and the yield of the whole fresh grass of T 3 treatment were the greatest,which were 1525 individuals/m^2,3001 cm^2/m^2,7022 g/m^2,and the length and width of flower were 1.50 cm and 1.67 cm,respectively.The accumulation of N,P,and K in the aerial part was the highest in T 3 treatment,which was 473.35 kg/hm^2,31.96 kg/hm^2,and 272.90 kg/hm^2,respectively.The accumulation of C of T 2 was 5781.73 kg/hm^2,which was significantly higher than that of T 1 treatment,and was not significantly different from T 3 treatment;The treatment had the highest accumulation of N,P,K,and C in the underground part,which were 17.93 kg/hm^2,1.23 kg/hm^2,12.91 kg/hm^2,3447.94 kg/hm^2,and the amount of carbon sequestration in T 3 treatment,which were all higher than other treatments,the difference was not significant.In the landscape utilization of green manure in orchards,the best sowing amount of V.sativa is 4 kg/667m^2,and the effect of viewing and utilization is the best.
