In view of the prospects for developing a unique hot spring agriculture in Guanziling to utilize the geothermal resources effectively, we carried out this research with the mixture of hot spring mud and loam in different proportions to cultivate several plants. The experiment was designed to figure out the suitable plants to be cultivated in Guanziling; moreover, to determine the adequate application rate of hot spring mud. The experimental group consists of five hot spring mud ratios: 25%, 20%, 15%, 10% and 5% mixed with loam, compared with 0% for the control group (without any hot spring mud but loam). The plants grown for the study are soybeans, sunflowers, water spinaches, mustards, Mino melons and tomatoes. Each plant with different proportioned mixture of hot spring mud and loam had three pots marked with A, B and C respectively for the experimental group, as well as one pot without hot spring mud for the control group. The plant growth including the height of the plant, the leaf length and width in each experimental and control group was measured, recorded and photographed. At the end, according to the averaged measurements, a chart analysis was conducted to investigate the influence factors. In the experiment, different plants and different proportioned mixtures of hot spring mud and loam were used as the mutagenic factors under the fixed condition of light source, location, and irrigation with proper amounts of tape water. The experimental results about the growth conditions of each plant indicated as follows: 1. soybeans: the 5% experimental group is better than the control group; 2. sunflowers: the 10% experimental group is better than the control group; 3. water spinaches: all the control groups are better than the experimental groups; of the experimental groups, 5% is the best; 4. mustards: all the control groups are slightly better than the experimental groups; of the experimental groups, 15% is the best. There was no significant difference between the experimental and control groups. 5. Mino melons: all the control groups are slightly better than the experimental groups; of the experimental groups, 5%is the best. There was no significant difference between the experimental and control groups. 6. tomatoes: all the experimental groups are better than the control groups; 15% is the best of them. The best mixed proportions of hot spring mud and loam are suggested as the following for planting in Guanziling: 1. 5% mixture of hot spring and loam for soybeans; 2. 10% mixture of hot spring and loam for sunflowers; 3. 5% mixture of hot spring and loam for water spinaches; 4. 15% mixture of hot spring and loam for mustards; 5. 5% mixture of hot spring and loam for Mino melons; 6. 15% mixture of hot spring and loam for tomatoes. The followings are better than the control groups. 1. 10% mixture of hot spring mud and loam for sunflowers; 2. 5%、10%、15%、20%、25% mixture of hot spring mud and loam for tomatoes; Keywords: Guanziling, hot spring mud, spa agriculture
