Based on the water and fertilizer coupling experiment in corn field,one-dimensional soil moisture content model containing the water uptake corn roots is used in this paper to simulate the evapotranspiration and the water uptake of corn roots and the change of soil pondage and soil moisture budget under the different water and fertilizer coupling conditions in corn field.
结果表明:在玉米生长初期以棵间蒸发为主,其后则是以植株蒸腾为主;玉米在30~40 cm土层吸水速率达到最大值;玉米灌水量为田间持水量的70%与85%对土壤0~80 cm土层贮水量的贡献是相等的,并且高肥力在一定程度上可增强根系的吸水能力,高灌水可增强玉米根系对养分的吸收利用,但对于提高水肥利用率来说,理想的处理为中肥中水。

This essay analyzes the method and procedure of ice-making recorded in Huai Nan Wan Bi Shu, and creatively proposes that the principle of "ice-making in summer" is refrigeration through the quick evaporation of water to absorb heat under low pressure, and that ice is made on the fine silk at the mouth of an urn, but not inside the urn at its bottom as it was conventionally thought. The essay points out three necessary conditions which should be fulfilled in order to realize "making ice in summer": low relative humidity (less than 26%), large volume of the urn (about 100 L) and proper air temperature (about 20℃).
