苏丹草是禾本科高梁属一年生优良牧草,原产地非洲北部苏丹,具有耐高温干旱的特性,素有“耐旱王”之称。赣江流域强度水土流失区土壤瘠薄,伏天地表温度可高达70℃左右,许多植物因难以抗御如此劣境而被淘汰。本试验希望通过对苏丹草适应能力的考验决定其取弃。考虑到试验成果今后在面上推广的实用价值,在试验地的改良方面(例如水土保持工程措施、加客土、施用化肥等)按实际合理确定治理标准,以利于被广大农户所接受。试验期内,苏丹草在整个生育阶段不到
Sudan grass is a grass sorghum biennial fine forage, origin of Sudan in northern Africa, with high temperature and drought characteristics, known as “drought-resistant king,” said. Soil erosion in the area of strength and soil erosion in the Ganjiang River basin is infertile. The surface temperature of volcanic days can reach as high as about 70 ℃. Many plants are eliminated due to the difficulty of fighting such adverse conditions. This experiment hopes to pass the Sudan grass adaptability test decided to abandon it. Considering the practical value of the promotion of experimental results on the surface in the future, the improvement of experimental sites (such as soil and water conservation engineering measures, plus guest land, fertilizers, etc.) should be based on the actual and reasonable treatment standards so as to be acceptable to the majority of farmers. During the trial period, sudangrass was not found throughout the reproductive period
