在甘肃中部半干旱条件下,采用种子处理方法研究了萘乙酸与元素混合营养液在豌豆上的增产效益及其机理.试验结累表明,在旱地豌豆上应用萘乙酸+硼、萘乙酸+钼和萘乙酸+磷等系列混合液浸种,能促进豌豆根系发育,延长根系发育期,提高抗旱性;延长根瘤存活期,增加单株有效根瘤重;促使幼苗早发,扩大叶面积,提高群体光合能力,增加植株干物质积累量和向生殖器官的分配比率,从而改善了豌豆主要经济性状的发育,尤其能显著增加双荚株率、有效分枝率、单株结荚数和粒重,最终使豌豆单位面积产量明显增加.由此结论,在旱地豌豆生产中应用该项技术是一项经济有效的增产途径.
In the semi-arid condition in the central part of Gansu, seed treatment methods were used to study the effects of naphthalene-acetic acid and elemental mixed nutrient solution on pea production efficiency and its mechanism.The results showed that the application of naphthalene acetic acid + boron, naphthaleneacetic acid + molybdenum And naphthalene acetic acid + phosphorus and other series of mixed liquid soaking, can promote pea root development, extend the root growth period and improve drought resistance; extend the survival of the nodule, increase the effective root nodule weight per plant; promote seedling early, expand the leaf area and increase photosynthesis Ability to increase plant dry matter accumulation and distribution ratio to reproductive organs, thereby improving the main economic traits pea development, in particular, can significantly increase the rate of bing pod, effective branching rate, pod number and grain weight per plant, and ultimately So pea yield per unit area increased significantly.Thus concluded that the application of dry-pea in the production of this technology is a cost-effective way to increase production.
