Camellia Ecological Cultivation Patterns And Dynamic Study. Undergrowth Nutrient

Oil-Tea belongs to Camellial.L.of Theaceae which is a unique and important edible woody oil plant in southern China .It is one of the four famous oil plants in the world.This article through the undergrowth pygmy camellia bean, peanut, green beans, green beans, cover grass, artificial fertilization and other ecological cultivation mode, To the same soil elements of camellia forest, the results showed that the dynamic research ,different ecological cultivation patterns for the undergrowth different camellia ,the influence of soil nutrient element each are not identical, different period of the same soil element changes also different. Experimental forest soil nutrient good overall camellia, but some effective element content is low, be soil utilization rate is low.(1)The content of soil elements shows downward trend by the increases of liquefaction-treatment , soil is obvious under lower in 20cm. State of the cultivation mode undergrowth different soil element influence camellia each are not identical, in 0-10cm soil,Mung bean plant can effectively enhance the woodlands of organic matter, total nitrogen, hydrolysis of nitrogen content ,Peanut planting improve organic matter, total phosphorus; At 0 to 20cm soil layer, planting mung beans can greatly improve the nitrogen, hydrolysis and organic content of nitrogen. Peanut planting improve organic matter, total phosphorus, rapidly-available potassium content. 20-40cm soil layer, peanut planting can greatly improve the soil total nitrogen, total phosphorus, rapidly-available potassium content, mung bean plant can greatly improve the hydrolysis and organic content of nitrogen, pygmy soybean planting can greatly improve the effective phosphorus, total potassium, and rapidly-available potassium content. 7 ways camellia forest, the most appropriate treatment is mung bean plant, followed by peanut planting. .(2)Ecological cultivation mode camellia different time dynamic change woodland element each are not identical, mung bean plant increase soil total phosphorus, artificial fertilization in a relatively short period of time could increase soil total potassium content. Various processing pattern P element change relatively gentle, green beans and green beans organic matter content increases obviously somehow. In the whole experiment cycle, 6 - October forests nutrient increase are relatively obvious, the November and December decline each number agreement.(3)in 10-20cm soil ,ecological cultivation mode that undergrowth in surface soils in camellia lifer were the maximum impact, P element . 10-20cm, 7 planting modes for the most obvious influence total potassium content, followed by total phosphorus and total nitrogen. 20-40cm soil ecological cultivation mode on the total phosphorus polarization. This study take seven kinds of ecological cultivation mode of forest soil large elements, produce a significant influence, the influence of soil total P is most obvious, nitrogen content of potassium were significantly.7 kinds of ecological cultivation patterns under the influence of N, P, K element whole content tree body than the soil, various processing mode, the comprehensive factors for camellia, mung bean plant nutrients undergrowth soil and trees promotes elements have total nitrogen, peanut cultivation to the increase of the content of artificial fertilizers are obviously promote, can increase total potassium content. Different ecological cultivation mode of woodland soil and trees body camellia presented significant positive correlation N elements, correlation coefficient were R> 0.928**inside with the contents of the elements N, the content of soil N elements increases. Soil total P content and tree body full P is related to soil total potassium content and content of tree reached significant correlation, correlation coefficient were R >0.899*.
