摘　　要：对旱地小麦/玉米带田集雨限量补灌条件下小麦带0～90cm土层土壤水分时空动态及其生长发育进行了分析,建立了0～30cm、30～60cm、60～90cm及0～90cm土层土壤含水量随时间变化的数学模型,并就旱地发展小麦/玉米带田提出了建议。This paper analyzed the spatio-temporal dynamic distribute of soil moisture in 0-90cm depth and growth of wheat under limited complementary irrigation with collected rainwater in zonal glebe with mixed planting wheat and maize. The mathematical model of soil moisture change in 0-30cm,30-60cn, 60-90cm, and 0-90cm depth along with time was set up in this paper. The author also gave some proposal for the development of zonal farmland with mixed planting wheat and maize in glebe.
