鎘比率 的英文怎麼說
中文拼音 [gébǐlǜ]
鎘比率
英文
cadmium ratio-
The results showed that under copper and cadmium stresses sulfur and organic fertilizer fertilization increased the amounts of re - transported storage matter and nitrogen and the rate of transported storage matter and nitrogen in the leaves, leaf sheaths, glumes and spike stalks of wheat and the total amounts of re - transported storage matter and nitrogen and the total rates of transported storage matter and nitrogen in winter wheat before flowering compared with their own controls and the fertilizations with high sulfur and organic fertilizer rates did not presented a remarkable regular effect
結果表明，與各自對照相比，銅、鎘脅迫下低施硫和有機肥的處理增加了小麥葉片、莖鞘、穎殼穗軸等營養器官花前貯藏物質、氮素的再運轉量和運轉率以及營養器官花前貯藏物質、氮素的總再運轉量和總運轉率，高施硫和有機肥的銅、鎘處理則規律性不明顯。When the concentration is low, 0 - 6 mg / kg, the content of cadmium in the root of alfalfa is lower than in the stern and leaf, but two times higher than the forage hugiene standard of our country. when the concentration is higher than 10mg / kg, the content of cadmium in the root is 20 times higher than the standard, but the content of cadmium in the soil decreased obviously, so alfalfa of this condition is the best alternative for renovating polluted soil. when 200mg / kg znic is added, the poison of cadmium is decreased dramatically with the grow time increasing, the cadmium effect on living number decreased
盆栽試驗中鎘對紫花苜蓿的出苗率、根、莖的生物量的影響與種子的萌發呈現同一規律；鎘在紫花苜蓿體內的含量也與土壤中鎘濃度有關：低濃度0 ? 6mg kg時，紫花苜蓿根部的鎘含量低於莖、葉中的鎘含量，但己超出我國飼料衛生標準2倍，濃度大於10mg / kg時，根部的鎘含量比飼料衛生標準高出20倍，而土壤中鎘含量大大降低，所以此時的紫花苜蓿是修復鎘污染土壤的較好的植物；當加200mg kg鋅后，鎘的毒害作用明顯減小，隨著生長時間的增長，生物量受鎘的影響也在減小，同時紫花苜蓿體內的鎘含量大幅度降低，有些己降到飼料標準以下。
