| 2. | Field capacity field moisture capacity 田间持水量 |
| 3. | Normal moisture capacity 正常持水量 |
| 4. | Sometime the matrix potential of soil water , moisture capacity and the total content of salt capacity in the soil have the same trends of change with depth 在包气带剖面中,在某时刻水土势、含水量、含盐量随深度变化的趋势相同。 |
| 5. | After yearly burning , soil moisture content , porosity , separate coefficient , capillary and field moisture capacity increased , however , soil saturated water retaining capacity and unit weight decreased 连年火烧使土壤含水率、孔隙度、分散系数、毛管持水量和田间持水量升高,而使土壤饱和持水量、容重下降。 |
| 6. | According to " forestland steady moisture capacity " , water deficiency in the former is only in surface and recovers timely after rain season . but in artificial forestland , there is an apparent shortage especially in deep layer , so it affects growth and development of vegetation 以“林地稳定持水量”为依据,天然林地水分亏缺不严重,只在浅层形成了轻度亏缺,并在雨季后能得到及时的恢复;同时这种亏缺并没有影响到了天然植被的发育与演替。 |
| 7. | The variation curves of yield and grain protein content with soil water content ( or nitrogen ) were convex in high fertility ( or soil water content were 70 % and 80 % of field maximum moisture capacity ) , and the soil water content ( or nitrogen levels ) before maximum protein content ( or maximum yield ) were the soil water content ( or nitrogen levels ) of coordinated variation of yield and grain protein content . [ conclusion ] coordinated variation of yield and grain protein content was possible in suitable condition 在高肥和土壤水分含量为田间最大持水量的70 %和80 %条件下,产量和蛋白质含量曲线均为凸型,蛋白质含量达到最大值之前对应的土壤水分含量为高肥条件下产量和蛋白质含量协同变化区间;产量达到最大值之前对应的施氮量为土壤水分含量为田间最大持水量的70 %和80 %条件下产量和蛋白质含量协同变化区间。 |
| 8. | 2 the comparisons between soil water deficiency in natural and artificial forest land show that : ( 1 ) the concept of " forestland steady moisture capacity " is presented and defined as the lowest soil water content that can not affect the forest regular growth primarily and cause inverse succession in community 2天然林地和人工林地土壤水分亏缺状况对比: ( 1 )提出了“林地土壤稳定持水量”的概念,初步定义为“不会影响到林分正常生长、发育,不会导致群落产生逆向演替所需的最低土壤含水量” 。 |
| 9. | The correlation coefficients between soil moisture regime and soil n2o emission rate were positive in the lower soil moisture regime ( 8 to 58 percent wfps ) , and soil n2o emission rate turned weaker and weaker when above the field moisture capacity ( 106 percent wfps ) . the highest n2o emission rate occurred in the field moisture capacity . soil n2o emission rate was higher in 30 than in 10 in the lower soil moisture regime ( 8 to 58 percent wfps ) , however , the trend was reverse when above the field moisture capacity ( 106 percent wfps ) 5水分含量低时( 8 58 wfps ) ,土壤中n20释放速率与土壤湿度呈正相关,并且随着温度升高释放速率增大;土壤湿度接近田间持水量( 58 wfps )时,释放速率最大;超过田间持水量( 106 wfps )时, n _ 2o释放速率显著降低,且30时的释放速率小于10时的速率。 |
