以重阳木为供试对象,将腐熟的稻谷壳粉、草炭土及未经处理的锯木屑等基质按一定的比例混合组成5种配方,进行重阳木生长情况研究试验,结果显示,各基质间重阳木苗高、地径、根长、根幅、侧根数、地上及地下干重及干质量比等指标变化明显,240d处理后,基质中添加30%的草炭或30%的稻壳粉能最大促进重阳木的生长,满足重阳木生长需要,基质A(30%的草炭)和基质C(30%的稻壳粉)对重阳木地上部生长明显好于其它基质,其中重阳木株高以基质A最高,但基质A和基质C差异不大,地径以基质C最大,且稻壳粉取材方便,可重复利用,价格低廉,可以作为重阳木基质大规模推广应用。
Taking Chongyang wood as the test object, five kinds of formulations such as decomposed rice hull flour, peat soil and unprocessed sawdust were mixed to form five kinds of prescriptions, and the growth and development of the plants were studied. The results showed that among the substrates The seedling height, root diameter, root length, root number, lateral root number, dry weight and dry weight ratio of ground and underground obviously changed obviously. After 240 days of treatment, 30% of peat or 30% Which can promote the growth of Chongyang wood greatly and meet the growth needs of Chongyang wood. The growth of shoots of Chongyang wood was significantly better than that of other substrates, with substrate A (30% of peat) and substrate C (30% of rice husk powder) Matrix A is the highest, but matrix A and matrix C are not significantly different. The diameter of matrix A is the largest in matrix C, and the husk rice powder is easy to be drawn, recyclable, inexpensive and can be used as a large-scale popularization and application of wood matrix in Chongyang.
