- W2368223839 abstract "The area of red soil in southern China is 2.112×10~6 km~2, accounting for 22% of the total area of China. Because of rich light, heat and water resources, this region is a major grain production base in China, and its potential for agricultural development is very great. However, the amount of water loss and soil erosion in this region is more than half of the total in China. Moreover, due to the unreasonable exploitation of mountainous resources as well as the relative concentration of rain seasons, the area and intensity of water loss and soil erosion in this region is increasingly enlarged. How to effectively conserve water and soil has become a major issue of concern to government at all levels. Nowadays, water loss and soil erosion is harnessed and conserved mainly by biological and engineering project measures such as tree and grass planting and transformation of slope into terrace, etc. It is difficult to achieve a harmonious development between ecological and economic benefit by adopting some conventional measures. Eulaliopsis binata belongs to Gramineae family, Eulaliopsis genus, and it is a perennial grass family fiber plant. Eulaliopsis binata possesses the characteristics of drought- and infertility-resistance and can easily be grown in almost every corner. Because of well-developed root system, quickly-established grass layer (the plant height of Eulaliopsis binata is commonly 1.5~2.0 m) and high covering degree of Eulaliopsis binata, its capacity to hold water and soil is very excellent. From the economic value viewpoint, Eulaliopsis binata is also a type of excellent raw material for many hand-weaving crafts and good raw material for superior quality paper, staple rayon and artificial silk. In particular as the raw material for paper manufacturing, its fiber content and quality are excellent among the herb fiber raw materials, and also better than poplar, birch, bamboo, etc. The mechanism and the benefits of soil and water conservation, the economic benefits, the biological characteristics and the main points of cultivation technique of Eulaliopsis binata have been studied in previous studies. In the present study, to investigate the influence of Eulaliopsis binata on soil quality is our major task. The maintenance and/or increase of soil quality is a fundamental premise for sustainable development of agriculture and is also consistent with the utilization of sustainable land use systems, which is widely accepted as one of the major word-wide concerns of today's society.The experimental site was situated at the experimental farm of Hunan Agricultural University, Hunan Province, South China, and located at N 28°15′latitude and E 113°02′longitude at an altitude of about 35m above mean sea level. This region has a humid mid-subtropical monsoon climate with a mean annual precipitation of about 1200~1700 mm, most of the rain falling between April and August, and a mean temperature of 16~18℃ with a minimum of 4.6℃ in January and a maximum of 29.7℃ in July. The soil of the experimental field is red soil that develops from Quarternary red clay. Three treatments were selected for this study: (1) EB (Eulaliopsis binata), planted in 1991. Fertilizers were applied in May (According to the standard of N 70 kg, P 14 kg, K 35 kg per hectare). Eulaliopsis binata (aboveground part) was harvested in November; (2) NG (natural grassland) consisting primarily of Cynodon dactylon, Vitex negundo, Festuca ovina, Setara viridis. No fertilizer was applied to the natural grassland; and (3) OG (Citrus), 10 years old. Hunan Province is a major orange production base, and citrus orange is also a dominant land utilization model in the red soil region of southern China. Residues from annual pruning were removed, while weeds were buried by harrowing. Fertilizers were applied at rates recommended for optimal production (the ratio of N, P and K is approximately 1∶0.6∶0.8). A randomized complete block design with three replications was adopted and plots size was 2 m×10 m.The effects of 10-year-old Eulaliopsis binata (EB) on soil" @default.
