对棕红壤（9701）、黄棕壤（9702）和灰潮土（9703）在25℃和40℃条件下，硼吸附一解吸特性，土壤硼吸附热以及温度对土壤础滞后解吸的影响进行了研究。结果表明，9701、9702和9703号土壤用的吸附热分别为－15．4、－15．6和－22．6kJ／mol，处于化学吸附热的范围，从热力学上证明了棚在土壤上专性吸附的存在。与25℃相比，40℃时土壤硼滞后解吸得到加强。与此相应，施入土壤中的外源硼，夏季与春季相比，其解吸率分别下降了38％、19％和7％。这些结果可以解释在夏季，土壤缺硼并不在于硼在土壤上的吸附减弱，而是土壤用滞后解吸在高温下得到加强的缘故。
The effects of boron adsorption-desorption, adsorption heat of soil boron and temperature on the lagged desorption of soil were studied under the conditions of 25 ℃ and 40 ℃ for brown red soil (9701), yellow brown soil (9702) and gray soil (9703) the study. The results showed that the adsorption heats of soil in 9701, 9702 and 9703 were -15.4, -15.6 and -22.6 kJ / mol, respectively, which were in the range of chemical adsorption heat. Thermodynamically, The existence of sexual adsorption. Compared with 25 ℃, 40 ℃ soil boron delayed desorption strengthened. Correspondingly, the desorption rate of exogenous boron applied to soil decreased 38%, 19% and 7% respectively in summer and spring. These results can explain that in summer, boron deficiency in soil is not due to the decrease of adsorption of boron on soil, but rather the enhancement of soil under high temperature by lagging desorption.
