Abstract:
Intensive management of C. oleifera has produced many pure C. oleifera plantations. The transmission of C. oleifera plantation will potentially affect soil C, N, and P pools as well as their stoichiometric characteristics both in top soil layer and vertical soil profile due to the intensive management. To understand changes in vertical pools and stoichiometric characteristics of soil C, N, and P as affected by intensive management of C. oleifera plantations, both mixed and pure C. oleifera plantations were studied. We conducted studies in five locations in Jiangxi, China with both pure and mixed C. oleifera plantations, to compare changes in vertical pools and stoichiometry of C, N, and P. Both C and N pools were significantly different between mixed and pure plantation types of C. oleifera. However, the ratio of C:N, C:P, and N:P was consistently higher in mixed plantations with C:P and N:P altered but C:N ratio did not change with soil depth. The intensive management significantly impact both C and N pools and the stoichiometry of C, N, and P. Intensive management of C. oleifera plantations decreased both C and N pools, especially at the depth of 30–50 cm soil layer. C. oleifera plantation alteration from mixed to pure should be considered in future forest management practice considering the substantial effects on soil element cycling and distribution along vertical soil profile.Keywords:

Fertilization is one of important measures to promote plant growth.According to three different fertilizer types and different ratios of N,P,K,with 9 treatments and a comparison group,by adopting the LSD multiple comparion research method on three-year-old Camellia oleifera,this paper analyzes different formula fertilization'effects on Camellia oleifera growth and psysiological characteristics.The results show that the different ratable fertilizer can stimulate the growth of young C.oleifera.Ⅴ,Ⅸ,Ⅲ and Ⅱ four treatments have the influence for diameter,height,crown and young branch in 9 treatments.They are the biggest differences in the content of chlorophyll of Camellia oleifera leaf and NO3-reductase activity simultaneously in Ⅵ、Ⅷ treatments.

The distribution of resources of Camellia Oleifera seed is described, and yield and fatty acid components and health functions of Camellia Oleifera seed are summarized. The concept of the first pressing Camellia Oleifera seed oil is offered, and extracting methods and processing technology of Camellia Oleifera seed are proposed by experiments. By improving quality of Camellia Oleifera seed oil, it will be more easy to export to international market and to promote industrialization of because nutrition and commercial value of Camellia Oleifera seed are as good as those of Olive oil.

Based on the survey data of farmers in Fujian,the paper analyzes the impacts of farmers' supply behavior of Camellia oleifera Abel using binary logistic regression model,and analyzes the main causes of the behavior.The study demonstrates the low enthusiasm of farmers' to expand the Camellia oleifera Abel supply and low motivation to plant Camellia oleifera Abel in the allocation of resources for farmers.The age of the head of household interviewed had a negative effect on the expansion of planting Camellia oleifera Abel and the education level,the existing acreage of Camellia oleifera Abel and the development state of local industrial development of Camellia oleifera Abel had a positive impact on the expansion of Camellia oleifera Abel planting.

The experiment of spraying different concentration of B9 on the new leaves surfaces of Camellia oleifera′s shoots were carried out,the results showed that:spraying B9 on the leaves surfaces would intensely inhibit the shoots growth, shorten the internode length and increase the number of short shoot;the chlorophyll content,the photosynthesis rate and the protein content of leaves would be increased respectiveTherefore,the leaf′s metabolism of Camellia oleifera willbe promoted

This paper expounds that the toxic action of gleditsis sinensis of Camellia oleifera on Colletotrichum Camalliae Massee is larger than that of any other secondary component of Camellia oleifera. Gleditsis sinensis element of Camellia oleifera is the principal material for inhibiting anthracnose of Camellia oleifera. The external experiment shows that gleditsis sinensis of Camellia oleifera transforms into gleditsis sinensis element of Camellia oleifera under the action of β-glycosidase. Also infers that β-glycosidase in plants conducts the enzymic reaction to produce gleditsis sinensis element, which will play an important part in the anthracnose-resistant mechanism.

Adulteration of Camellia oleifera Abel. oil with other cheaper oil has been a long-term problem in Taiwan because the price of Camellia oleifera Abel. oil is much higher than that of other edible oils due to its distinguished physiological properties. To develop an efficient method for determining the authenticity of Camellia oleifera Abel. oil is of great importance. In previous study (Appl. Spectrosc. 2003, 57, 413), we showed that the Raman intensity ratio of ν1656/ν1439 was capable of reflecting precisely the degree of unsaturation in edible oils. Accordingly, we further present this Raman method to determine the authenticity of Camellia oleifera Abel. oil. It showed that the intensity ratio (Iν1656/ν1439) changed concomitantly with the magnitude of double bonds in the binary mixtures of Camellia oleifera Abel. oil blended with other edible oil. A linear relationship with a high correlation coefficient (R2 = 0.9938) between the Raman intensity ratio of ν1656/ν1439 and the percentage of Camellia oleifera Abel. oil was obtained, which could be used to determine the authenticity of Camellia oleifera Abel. oils collected from various markets. It shows that FT-Raman spectroscopy provides a direct, simple, rapid, and non-invasive method to probe the authenticity of Camellia oleifera Abel. oil.
