Abstract: In order to eliminate the stink, live earthworm, eggs, which were harmful to the sale of wormcast on network, the wormcast was made into pelletization and the hydroponic experiment of Pennywort and Tradescantia zebrine were conducted. The effect of wormcast particle on ornamental plant, the way of wormcast in indoor plant cultivation was studied and the feasibility of wormcast pelletization and the sale of wormcast particle on network were assessed. The results showed that pelletization could eliminate the stink, live earthworm, eggs of the wormcast and the wormcast particle could enhance the growth of Pennywort and Tradescantia zebrina. The network market prospect of wormcast pelletization was well.
Key words: wormcast; plant; Pennywort; Tradescantia zebrina; growth; pelletization of wormcast
蚯蚓糞營養(yǎng)豐富,富含有機酸、蛋白質、氮、磷、鉀及微生物,適合所有植物,素有“肥中之王”的美譽。蚯蚓糞能夠有效改善土壤肥力,提高作物產量及品質,在農田、果園、有機蔬菜種植基地應用廣泛。隨著現代生活有機種植理念的不斷深入,蚯蚓糞等有機肥料不斷進入到家庭花卉、蔬菜的種植當中。關于蚯蚓糞作為土壤有機肥的應用和研究比較多,但作為水肥的研究比較少,而家庭種植的花卉植物,有一大部分就是水培方式。現代生活網購平臺方便快捷,使得人們越來越習慣于從網上購買有機肥、營養(yǎng)土,而蚯蚓糞便是其中最熱銷的有機肥品種之一。目前,網絡市場上銷售的蚯蚓糞基本上只經過簡單的風干過篩處理就裝袋銷售,這樣的蚯蚓糞水分含量差異大,簡單的過篩處理并不能處理掉生產過程帶入的雜菌。……
