查询词典 moisture content

In the Mu Us desert, either vertical distributions of soil moisture isogram before irrigation or vertical distributions of soil moisture isogram after irrigation shows obviously vertical-layered character. When the irrigation is finished 24 hours later, there is little correlation between vertical distributions of soil moisture isogram before irrigation and vertical distributions of soil moisture isogram after irrigation. All of probability distribution of soil water content before irrigation are left-skewed distribution, but some of probability distribution of soil water content after irrigation is left-skewed distribution, some is right-skewed distribution or normal distribution. The distributed pattern shows different between the probability distribution of water depth of rain gauge and that of soil moisture in horizontal section of different depth. There is close correlation between the distribution of water depth of rain gauge and that of soil moisture in horizontal section, but the correlation debases as the horizontal section turns deeper. Also after irrigation close correlation occurs between the distribution of soil moisture of layers bordering upon each other, but which reduces with space of different layers being larger.

2Soil column leachate experiment shows, soil texture and soil section form are the main factors affecting the nitrate leaching; in soil organic fertilizer produce a nitrate leaching process, during five-month experiment, nitrate content has be increasing in leakage solution, organic fertilizer applying decrease the pH and increase the electric conduction of leakage solution, there is positive action between nitrate content in leakage solution and electric conduction, which shows that nitrate-N accumulation during organic fertilizer applying is one of the main factors for soil salification; for decrease the leaching of the nitrate-N in soil, in sandy moisture soil the best amount of organic fertilizer should be 7.5～ 15 t·hm~(-2), in Loamy moisture

在小麦-玉米轮作体系上投入化肥氮300kg·hm~(-2)N和有机肥22.3t·hm~(-2)折N261.2kg·hm~(-2，能使农田氮素收支达到平衡，在兼顾环境效益的基础上获得了较高的产量效益。并通过肥料效应函数和硝态氮累积效应函数进一步预测最佳施肥组合，即化肥氮施用量为N226.5kg·hm~(-2)，有机肥用量为39.9t·hm~(-2)折N466.8kg·hm~(-2，其中小麦季施化肥氮105.85kg·hm~(-2)N、有机肥30t·hm~(-2)折N351kg·hm~(-2，玉米季施化肥氮120kg·hm~(-2)N，有机肥9.9t·hm~(-2)折N115.8kg·hm~(-2。同时，磷素平衡分析表明，在施用有机肥的基础之上，化学磷肥的施用量应适量的减少或不施。

Temporal and spatialcorrelation of Soil moisture under vertical direction was affected by some factor such asmeteorology, land use and fertilization measures. All siol moisture in different layers hastemporal and spatial correlation when soil moisture fluctuates of surface layer becausestability, but influence ability of each factor is not the same. For example, meteorologyhas most strong impact on temporal and spatial correlation of soil water content.

在气象条件较稳定的情况下，不同植被覆盖和不同施肥措施下各土层含水量之间都具有较强的时空相关性，随着气象条件波动加剧，各土层土壤含水量的时间相关性和空间相关性都降低；植被因素相对气象条件对各土层含水量的时间自相关性影响较小，而对各土层土壤含水量之间的空间相关性影响较大，裸地和农田各土层土壤含水量之间的空间相关性相对林地和草地较弱；不同的施肥水平都削弱了土壤各土层含水量的时空相关性。

Over a 20-year period there was no increase in soil water content in the grazed grassland at depths of 2～9.9 m. There was a small increase(0.5～3.7 mm/a) in soil water content in the protected grassland, however the slow rate of increase suggests that at least 150 years would be needed for ungrazed grassland soils to regain water content similar to that present prior to planting trees. Recharge of deep soil moisture was faster in cropland(15 mm/a), but at this rate it would still take about 40 years to restore cropland soil water content to pre-plantation conditions.

结果表明，人工林死后的放牧荒坡在20a的时间里，其土壤水分没有补偿；人工林死后的保护草地土壤水分有微弱恢复迹象，但年恢复速度在0.5～3.7 mm之间，以这样的速度恢复到持续放牧荒坡的土壤含水量，至少需要150a以上；林后农地土壤含水量有恢复趋势，年平均恢复速度为15 mm左右，其土壤含水量要恢复到持续农地当前的水平，大约需要40a的时间。

This article through to the small leaf oak branch moisture contentdetermination and the analysis, take the small leaf oak's bough highlyas an independent variable, take the corresponding high branchmoisture content as the dependent variable,Uses the linear theory to construct the bough moisture contentestimation mathematical model, studies the small leaf oak boughmoisture content the distributed rule.

7 Percent of rain water was kept in plant after 7 days. The change of plant water δD indicated the water use efficiency of plant was effected by micrometeorology factors. The rising of soil temperature prevented plant root absorbing soil water, and soil moisture content facilitated plant root absorbing soil water.

大雨（65.3mm）降水后，雨水能够更快地渗入植物的根系层，对干旱区植物的补水作用较强，植物能够及时利用大雨，而且雨水在植物体内保持的时间较长，7天后植物体内保持雨水的41.8-53.7％。
