edaphic formation

In the present study , a compartment cultivation system and histochemical staining were used to investigate the influence of soil available p level , plant p status and soil organic p on the growth and metabolic activity of am fungi . differences in metabolic activity among am fungal isolates and the relationship between metabolic activity and mycorrhizal effectiveness were al so investigated . in addition , am fungi from a wide range of environmental conditions ( originally isolated from north , central and south china ) were used to study the ecological adaptability of am fungi and the influence of edaphic conditions on am fungal growth and metabolic activity 本研究采用分室根箱、組織化學等手段研究了土壤施磷水平、植物磷營養狀況、土壤有機磷對am真菌生長和代謝活性的影響;不同am真菌的代謝活性及其與菌根效應之間的關系,并對我國華北、華中和華南地區篩選出的高效菌株進行了生態適應性的比較,以期在理論上闡述宿主植物生長狀況及土壤條件對菌根真菌生長和代謝活性的調控機制,篩選出具有廣泛生態適應性的am菌株。

It does not need much area , not any pollution , not consuming much electricity power , not need much cost . gshp combined floor radiation air - conditioning system possess high seasonal average cop value and great capacity of edaphic depositing heat energy , can ease up supplied water temperature fluctuating with the change of the outdoor air temperature 地源熱泵技術聯合地板輻射對房間進行冷暖聯供的形式,具有地源熱泵季節性平均性能系數高、土壤蓄熱能力強、能緩解空氣源熱泵存在的供冷供熱能力隨環境溫度波動大的矛盾等優點。

The rate of contribution of various edaphic physical parameters is different from parameter of soil water infiltration model in different soil texture and husbandry condition , so independent variable factor and priority are different in regression models . the predicted results are satisfactory in correlation husbandry condition 在不同的土壤質地和不同的耕作條件下,土壤的各種物理參數對土壤的水分入滲模型參數影響程度不同,因此引入到回歸模型中的自變量因子不同,引入的先后次序不同。

According to relevant data , all sorts of heavy metal are differred as a result of migratory ability , great majority gathers in the earth ' s surface decompose , the edaphic heavy metal that 50 years accumulative total value is less than a country to set is restricted 根據相關資料,各種重金屬由于遷移能力差,大多數在地表聚集分解, 50年累計值小于國家規定的土壤重金屬限制。

Head push experiment of mulberry of british the name of a river in shaanxi and henan provinces to stand , have edaphic sample of near 200 years , make the important material that studies climate change and soil now 首推英國洛桑實驗站,有將近兩百年的土壤樣品,現在成為研究氣候變化和土壤的重要資料。

Edaphic factors the physical , chemical , and biological characteristics of the soil that together form an important component of the habitat because of their influence on plant distribution 土壤因子:包括土壤的物理、化學和生物特征,因其對植物分布的影響,共同構成了棲息地的重要成分。

A reservoir is built in housetop , have structure of wall of edaphic lay aside , some of alga , fish is put inside , form small - sized ecosystem with assuring water quality fresh 在屋頂建設一個蓄水池,有土壤貯壁結構,里面放些藻類、魚類,形成小型生態系統以保證水質的新鮮。
