The Study On Fertility Status Of Soil Reclaimed From Hilly Land For Young Camellia And Effect Of Interplanting Green Manure Crops And Young Camellia Oleifera

Camellia oleifera is a peculiar xylophyta edible oil-bearing tree in the South of China, widely planted in southern China hilly slope land. Due to the barren and acidic soil of the new young Camellia base, Camellia grow slowly,and the economic efficiency is low,with the addition of the destruction of topsoil, natural vegetation is damaged, and the surface coverage is poor, causing serious soil erosion. Therefore, how to speed up the rapid growth of young Camellia, and prevention of soil erosion of young Camellia Forest, is a key technical problem to solve for China’s Camellia production. Aim to provide a scientific basis for the soil fertility and rapid growth and high yield of young Camellia oleifera base.The Soil fertility status under different intercropping pattern of young camellia and Purple sandstone and Conglomerate Hilly regions of Liuyang in Hunan Province were researched through the field investigation, field experiment and laboratory analysis. The results showed as follows:(1) Among different slope positions of hilly land for young Camellia oleifera base Soil acidification is very serious, soil protecting fertilizer ability is poor.The soil organic matter, total N, hydrolysable N, available P, available K content lack, total P,total K content is appropriate. The soil available Ca, Mg content is rich. The content of soil available Fe, B was rich,while available Zn was medium and available Mn, Cu were lack.(2) The pH value of every processing soil under the intercropping mode of hilly land for young Camellia and different green manure crops were not significant and were from3.8to4.7, and the area of soil acidifycation has been extremely serious; The content of soil organic matter and the soil fertility and the growth of the young forest can be significantly improved in Hilly Land for young Camellia interplanting green manure crops. (3) The difference among every processing camellia plant height, crown breadth under the intercropping mode of hilly land for young Camellia and different green manure crops was not significant. Hilly Land for young Camellia interplanting green manure crops with application of N, P, K fertilizer at the same time, can significantly promote the growth of camellia. From the perspective of the green manure production of nearly two years, deal with fertilizer and interplanting winter green manure Lolium multiflorum Lam production is much higher than other processing. This shows in Hilly Land for young Camellia interplanting green manure crops, winter green manure Lolium multiflorum Lam can gain higher yield of green manure, can improve the high yield and high efficiency production of camellia.
