Predicting Potential Distribution and Evaluating Suitable Soil Condition of Oil Tea Camellia in China

Abstract

Oil tea Camellia, as a major cash and oil crop, has a high status in the forestry cultivation systems in China. To meet the current market demand for oil tea Camellia, its potential distribution and suitable soil condition was researched, to instruct its cultivation and popularization. The potential distribution of oil tea Camellia in China was predicted by the maximum entropy model, using global environmental and soil databases. Then, we collected 10-year literature data about oil tea Camellia soil and applied multiple imputation and factor modeling for an in-depth analysis of soil suitability for growing of oil tea Camellia. The prediction indicated that oil tea Camellia was mainly distributed in Hunan, Jiangxi, Zhejiang, Hainan, East Hubei, Southwest Anhui and most of Guangdong. Climatic factors were more influential than soil factors. The minimum temperature of the coldest month, mean temperature of the coldest quarter and annual precipitation were the most significant contributors to the habitat suitability distribution. In the cultivated area of oil tea Camellia, soil fertility was poor, organic matter was the most significant factor for the soil conditions. Based on climatic and soil factor analyses, our data suggest there is a great potential to spread the oil tea Camellia cultivation industry.

Soil C-N-P pools and stoichiometry as affected by intensive management of camellia oleifera plantations

“…The main distribution area of C. oleifera is red soil area in subtropical China, especially Jiangxi and Hunan province [12,14]. Plantations of C. oleifera could be managed in hilly areas with lower nutrients that are not suitable for development of agricultural farmland [14,15]. The development of C. oleifera plantation could thereby increase land use efficiency and provide edible oil, increasing both living standard and income of local citizens [15].…”

Cultivation of C. oleifera has been strongly supported and encouraged by the government in the past twenty years, increasing the distribution area of C. oleifera up to three million ha [15].…”

The intensive management of C. oleifera, especially fertilization, will impact soil C, N, and P balance by alterations in soil elements input [1,3].…”

Biochar Is Comparable to Dicyandiamide in the Mitigation of Nitrous Oxide Emissions from Camellia oleifera Abel. Fields

“…is one of the world's four main woody edible oil crops, with a long cultivation history and wide cultivation area in subtropical China [17] due to the beneficial effects of its oil on human health [18]. C. oleifera is mainly cultivated in Typic Hapludult Ultisols (red soil) with lower soil fertility [17,19]. Therefore, intensive N input has been used to increase the yield of C. oleifera oil.…”

Different Nitrate and Ammonium Ratios Affect Growth and Physiological Characteristics of Camellia oleifera Abel. Seedlings

“…With the increasing demand for self-sufficiency in cooking oil [3], the production of C. oleifera has significantly increased over the last 20 years. The current cultivated area for C. oleifera is more than three million ha in China [6,7].…”
