混合改良剂改善园林废弃物堆肥基质品质提高育苗效果
为改善堆肥基质品质，促进园林废弃物资源化利用，针对堆肥产品高盐碱性质，以竹酢液、麦饭石2种物质为混合改良剂配施于园林废弃物堆肥基质中，以种子萌发、幼苗生长以及改良后基质pH值、电导率为评价指标，以期筛选出适宜园林废弃物堆肥基质的最优改良配比。结果表明，添加竹酢液、麦饭石混合改良剂的处理对降低基质pH值、电导率有显著作用，下降幅度分别为pH值：1.15～1.20、电导率：1839～2076μS/cm；施加改良剂可有效提高种子发芽率、发芽势、发芽指数、活力指数；改良剂的施用促进幼苗根的生长发育，使植株叶片叶绿素含量升高，从而导致根质量、根长、株高的增高；将改良后基质之间各指标进行比较，基质施加稀释...

| Abstract_FL | Large amount micromolecule organic matters and saline ions was produced during the composting from green wastes, leading to low pH value and high electrical conductivity (EC), and so on. These problems will hurt the seedling in the course of cultivation.In order to increase the effective use of green waste and improve the quality of growing substrate, 2 kinds of ameliorants, including bamboo vinegar (the dilution ratio of 500 or 1 000, the addition content of 500 mL/g ) and medical stone (the addition content of 20, 40, 80 g/kg), were applied into green waste composting. Seed germination parameters, seedling growth, substrate pH value and EC, were measured as screening indexes to screen out their proportioning for effectively ameliorating growing substrate. The results showed that the addition of bamboo vinegar and medical stone decreased pH value and EC of green waste compost substrates effectively. Compared with the control, bamboo vinegar and medical stone addition decreased pH value by 1.15-1.20 and EC by 1 839-2 076μS/cm in growing substrate. The addition of bamboo vinegar and medical stone had very significant effect on seed germination, and largely increased germination percentage, germination potential, germination index and vigor index. Compared with the control, germination percentage, germination potential, germination index and vigor index of the treatment E (1 000 times 500 mL/kg dilution bamboo vinegar + 40 g/kg medical stone) were higher by 41.66%, 44.99%, 9.70, 99.75. The treatments with the addition of bamboo vinegar and medical stone promoted seedling growth, and also increased chlorophyll contents, which accordingly increased the root weight, root length and seedling weight. The root length, chlorophyll content, plant height and seedling weight were high than the control by 4.01 cm, 0.3375 mg/kg, 0.139 g and 1.380 cm, respectively. Therefore, the treatments of applying 500 mL/kg 1 000 times dilution bamboo vinegar + 40 g/kg medical stone to the green waste compost substrates has the best effect. The results of the study will promote green waste compost waste used as substrate utilization. |
