秸秆覆盖条件下土壤水分运动的数值模拟

MATHEMATICAL SIMULATION OF MOVEMENT OF WATER IN SOIL UNDER THE COVERING CONDITION WITH STRAW

本文以等温模型为基础，给出了秸秆全覆盖条件下冬小麦田间层状土壤水分运动的数学模型，并与实测数据进行了比较，数值模拟结果和农田实测值吻合良好，因而本模型可有效地用于秸秆覆盖条件下土壤墒情的预报工作。

This paper,based on the model of high temperturs,given the mathematical model of water movement in soil layer of the field of winter wheat under the condition of covering straw,compared with the data of practical determination,the result of mathematical simulation coincided with the data of practical determination,therefore the model can be used in forecast of water in soil under the condition of coy.ering with straw.
