摘  要:
用土壤的农业水文学特征 ,如土壤质地、土壤容量、最低田间含水量和萎蔫下的土壤含水量对作物灌溉的规范化进行了研究。结果发现 ,如果考虑作物的灌溉制度 ,由有效贮水量决定的土层中的灌溉前含水量为一常数 ,即在有效植物生长期之前 ,土层中的灌溉前含水量为 50 % ,而有有效植物生长期则为 70 %。土层有效贮水量为决定不同土壤灌溉前含水量的一个概略性指标

摘  要:
Standardization of crop irrigation using the agrohydrological characteristics, such as texture,bulk density, soil moisture under the lowest water capacity and wilting moisture is investigated . It is found out that pre irrigating moisture of the soil horizon determined by the available moisture savings of the soil horizon is constant if irrigating crops regimes are considered. Pre irrigating moisture of available moisture savings is 50% before active vegetation phase and 70% during the active vegetation phase. Available moisture savings is a summarizing indicator for all soil differences determining pre irrigating soil moisture.
