平欧杂种榛林下套种牧草对坚果产量和品质的影响

Effect of Interplanting Forage under Corylus heterophylla×C.avellana Plantation on Production and Quality of Nuts

以章古台地区沙地栽培的平欧杂种榛达维、辽榛3号和辽榛7号3个品种(系)为研究对象,进行榛树行间套种豆科牧草试验,研究平欧杂种榛林下套种牧草对坚果产量和品质的影响。结果表明:平欧杂种榛株产主要受果苞数的影响,两者之间呈极显著的正相关(P<0.01),相关系数为0.992;平欧杂种榛林下套种牧草后,可以显著提高果苞数,不同品种间提高程度不同,辽榛7号提高程度最大,提高了96.71%;平欧杂种榛林下套种牧草后,坚果的蛋白质、总糖、淀粉和脂肪含量均得到了显著提高,明显改善了坚果的内在品质。

Taking Corylus heterophylla×C.avellana‘Dawei’,Corylus heterophylla×C.avellana‘Liaozhen 3’and Corylus heterophylla×corylus avellana‘Liaozhen 7’in the sandy land of Zhanggutai area as research objects,Corylus heterophylla×corylus avellana inbred lines with grazing experiments were conducted.The effect of interplanting forage under Corylus heterophylla×C.avellana plantation on production and quality of nuts were studied.Result shows that the yield of Corylus heterophylla×corylus avellana was mainly affected by the number of fruit buds,there is a very significant positive correlation between the two(P<0.01),and the correlation coefficient is 0.992;in order to increase the number of fruit buds,the degree of improvement is different among different varieties.Corylus heterophylla×corylus avellana‘Liaozhen 7’improve the most,increasing by 96.71%after interplanting with forage under Corylus heterophylla×corylus avellana plantation.The content of protein,total sugar,starch&fat in nuts has been significantly improved after interplanting with forage under Corylus heterophylla×corylus avellana plantation.
