Effects of different measurements on soil salinity dynamics under cropping 生物型煤粉煤灰對堿土水溶性離子含量和透水性的影響
Soil salinity is one of the most significant abiotic stress for plant agriculture 土壤鹽漬是影響植物生長的重要脅迫條件,嚴(yán)重制約著農(nóng)業(yè)生產(chǎn)和土地利用。
This indicates that soil salinity will transport to middle and deep layer from superficial layer 拓寬了ann的應(yīng)用領(lǐng)域,具有一定的創(chuàng)新特色和學(xué)科融合的優(yōu)勢。
The inferred water quality , soil salinity and hydrogeologic units are quite consistent with what is said in the hydrogeologic reconnaissance report 所推斷的水質(zhì)和土壤含鹽量與大的水文地質(zhì)單元和1 : 20萬水文地質(zhì)普查報告都吻合得很好,且細(xì)節(jié)更為清楚。
The results of correlation comprehensive array analysis indicated that the water seepage from canal systems was the main cause resulting in the uprising of underground water table and the increase of soil salinity in qyrid 同時通過關(guān)聯(lián)度綜合排序分析,確定出渠系滲漏是造成灌區(qū)地下水位高、土壤鹽漬化的主要原因。
The purpose of this web site is to share my experiences with workers in any country on water logging in agricultural lands , irrigation induced soil salinity , subsurface drainage for agriculture ( horizontal and vertical ) , reuse of groundwater , ground - water hydraulics , ( geo ) hydrology , rainfall and surface runoff relations , reclamation and improvement of water logged saline , salty , sodic alkaline , and acid sulphate soils , plant growth , crop production and responses as well as statistical analysis consisting of segmented linear regression and cumulative frequency distributions 描述:探討農(nóng)業(yè)耕地的水澇問題;灌溉導(dǎo)致的土壤鹽堿化;地表灌溉;地下水的再利用;地下水水力學(xué);雨水與水流失的關(guān)系;淺地表排水;土壤開墾及水澇,酸性,堿性土壤的改良;片段線形回歸和累積頻數(shù)分布的統(tǒng)計分析等。
百科解釋
Soil salinity is the salt content in the soil; the process of increasing the salt content is known as salination. from "Soil salinity" in WaterWiki, the on-line Knowledge and Collaboration Tool of the Community of Practice (CoP) on Water- and UNDP-related activities in Central and South-Eastern Europe, Caucasus and Central Asia.
