Abstract

This paper discusses growth rules of Hedysarum polybotrys Hand-Mazz. With playgoskite being added, a set of production technologies is established for Hedysarun polybotrys Hand-Mazz. The single factor randomized block is designed in the experiment to study the growth development and yield of Hedysarum polybotrys Hand-Mazz, under 5 types of treatments with playgoskite of 0, 750, 1500, 2250 and 3000kg/hm2. The results show that playgoskite can enhance the stilbazolium height, main root length, root diameter, dry material accumulation quantity in ground and root and the yield of Hedysarum polybotrys Hand-Mazz, when it is used in the range of 750~3000kg/hm2. And the yield is the highest, when it is used in 1500kg/hm2, with an increase of 23.44%(P＜0.01) compared to the control group, and with optimum overall characteristics. The next comes with 1500kg/hm2. This study provides an important scientific basis for reasonably using N, P and K fertilizers and playgoskite in the cultivation of Hedysarum polybotrys Hand-Mazz.
