Nutrient Accumulation And Distribution Of The Bamboos Of Bambusa Multiplex In Different Plants Arrangement

In garden application, there are 2 kinds of planting patterns, including the mass planting and the linear planting. The different planting methods will have an effect on the nutrient accumulation and soil nutrient. In this study, establishing standard sample land in bamboo forest of Zhejiang Agricultural and Forest University.From July 2014 to June 2015, based on the investigation of sample plots, respectively,to collect different age standard plant leaves, branches, straw and forest soil. Analyzing of the dynamic and soil nutrient content of 2 different allocation and distribution, can provide scientific basis for the design of the filial Bambusa multiplex. the main results showed:(1) In terms of the soil physical and chemical properties of Bambusa multiplex foerst the, mass planting is superior to the linear planting on the whole. Due to the mass planting were disturbed by human less activitives and, had a good ecological cycle system, supplying sufficient nutrient.(2) The contents of N, P, K, N, P were higher from July to September, while the content of N, P and K in different organs was lower from March to December. The contents of N, P, N, K, P and N in the leaves of the mass planting were higher than those of the linear planting. The contents of P, K and N in the leaves of the leaves decreased with age.(3) Different distribution of plant species had a significant effect on the biomass and nutrient storage of Bambusa multiplex’s leaf, branches, and stalk, but did not change the distribution of the different organs. The total biomass of Bambusa multiplex in the upper part showed that the mass planting 23.4 t·hm-2 greater than the linear planting(8.69 t hm-2).The biomass of the mass planting was2.7times of the linear planting. And the biomass of the different organs is in order of culms leaves branches, The biomass of bamboo stalk occupied about 77% of the upper biomass.The total phosphorus, potassium nutrient and total reserves of Bambusa multiplex were 314 kg hm-2in the mass planting and, 94 kg hm-2 in the linear planting. And the nutrient reserves of total N, P, K was in order of stem > leaf > branch(4) There was no significant correlation between soil nutrients and plant nutrient elements, and the correlation between K and N existed in different organs, and there was a strong correlation between different physical and chemical properties of soil.
