Establishment and Verification of Soil Moisture Model for Cotton Cultivation with Drip Irrigation under Mulch
LIU Hao, MA Fuyu, CUI Jing, SUN Huijian
Field experiment was conducted to investigate spatial and temporal variation of soil moisture and its yield under irrigation frequency and amount of different treatments during flowering-bolling stage of hybrid cotton.Thus efficient irrigation strategy may be provided and soil moisture model under this irrigation strategy could be established for hybrid cotton in Northern Xinjiang.The result showed that 5d30mm irrigation mode was recommended for hybrid cotton growth in Northern Xinjiang, 75% of relative soil water content could be recognized as the critical value of soil moisture.Moreover, the soil moisture model was established as followed:y=-1.321x2+2.855x-0.6178(R2=0.945), which can precisely simulate soil
spatial and temporal variation
