Effects Of Slag Fertilizer On Foliar Nutrition Dynamics Of Phyllostachys Nidularia Munro F.Nidularia

With the growing application of white Phyllostachys nidularia munro f. nidularia usage, traditional fertilization cannot meet the need of high and steady yield. Slag fertilizer as the specific and new bamboo fertilizer is developing into a significant fertilizer application direction in the21st century, due to the special capsule structure and ability to satisfy the requirement of sustainability.Nevertheless, more research is needed for its efficacy and production because of the inadequacy of application cases.Phyllostachys nidularia munro f. nidularia is one of the most important dual-use bamboo plant in the province of Sichuan and even in the whole southwest areas, which is widely used in the producing and greening of gardens.This paper is focusing on Phyllostachys nidularia munro f. nidularia, researching into the dynamic nutrition efficacy of specific slag fertilizer in Shangli, Ya’an,analyzing the effect difference between common and slag fertilizer through the comparison of the two groups with equal efficacious nutrition, and analyzing the effect difference between fertilizer with diversified nutrition proportion by comparing NPK and slag fertilizer mixed at different mixing ratio.Considering the experiment objects above, this paper mainly analyzed4index including total N, total P, total K and N/P via ANOVA and multiple comparisons. The result is as follows:(1)Fertilization significantly enhances the nutrition portion of1-year-old Phyllostachys nidularia munro f. nidularia(2)The usage of NPK fertilizer has a greater effect on1-year-old Phyllostachys nidularia munro f. nidularia while the effect on many-year-old is not significantly different by two fertilizers. A comprehensive analysis of N, P and K leads to the conclusion that for1-year-old bamboo, NPK fertilizer is more efficacious and can satisfy the need of large amount of nutrition. The situation is different in the case of many-year-old bamboo, in which there is no difference between two types of fertilizer. Therefore, it is applicable to use NPK fertilizer for new grown bamboo and change to slag fertilizer after maturation, or appropriately increase the amount of slag fertilizer in new grown stage; (3)The effect varies from one mixing ratio of fertilizer to another. Choosing NPK1for NPK and KZF2for slag brings about expected efficacy. In1-year-old bamboo, there is significantly efficacious result for the rest3of4indexes chosen except total K in NPK1and NPK2within the group of NPK, whereas within the group of slag, the difference is significant in total N, total K and N/P except foliar total N, for which KZF2is less efficacious. For many-year-old bamboo, KZF2and NPK1work better compared to their counterparts within each group separately. Hence, choosing NPK1for NPK fertilizer with using lesser K fertilizer and KZF2for slag fertilizer with using more total fertilizer.Based on the results above, the analysis of foliar nutrition in Phyllostachys nidularia munro f. nidularia fertilized by slag and NPK helps to draw the conclusion that there is no significant difference between the effects on the dynamic foliar nutrition content. To integrate the considerations of economic input, labor costs, environment assessment and policy conditions, there are broad prospects in the usage of specific slag fertilizer for bamboo culturing despite further study is needed.
