茶树根系吸收矿质元素茶树根系吸收矿质元素absorption of mineral elements by the root system of tea plant茶树根系吸收矿质元素、absorption()fmineral elements by the root systemof tea Plant)茶树根系从土壤和水中吸收离子状态元素的过程。根系对矿质元素的吸收是一个生理过程.受到内外因素的形响。茶树根系是吸收矿质元素的主要器官。茶树根系吸收矿质元素以根尖为多，离幼根尖端2一3匣米处礴的移动l为最大。根毛部是根尖吸收矿质离子最活跃的区城。根系吸收矿质离子有被动吸收和主动吸收(或主动运拍)。被动吸收不需要代谢供能，包括扩散、离子交换吸附，杜南(Donnan)平衡:主动吸收是靠细胞代谢供能而递浓度差吸收矿质离子。矿质离子从根部表面进入木质部有两条途径:一是经共质体的主动运愉;二是经质外体从内皮层进入共质体到中柱。一般说来，主动吸收是根系吸收矿质的主要形式。茶树根系对矿质的吸收受年龄、生育期、代谢强弱、修剪等的形晌。成龄茶树的吸收利用率.氮是50%，确是22.5%，钾是45%。幼龄茶树分别为25%、4%、7.5%。在全年中，氮和钾的吸收主要集中在4一11月:礴则集中在4一6月和9月，各占总吸收最的均%和38%。茶树修剪后一个月左右，根系对氮、碑、钾的吸收还在减少，氮和钾的吸收恢复较快，恢复后，以对氮的吸收为最迅速。土坡条件影响茶树根系对矿质的吸收。①土坡水分和氧气:土坡通气良好，氧气充足，CO:浓度减少，呼吸增强，促进根系生长和对水、肥的吸收;土坡水分过多，氧气缺乏，CO:浓度增高，抑制有筑呼吸，降低根系对矿质的吸收。土城水分不足，限制矿质盐类的溶解;燕腾速率降低，亦阻碍矿质离子向上运愉。因此.土坡水分常控制或促进茶树对矿质元素的吸收、利用。②上城溶液浓度:在一定范围内，根系吸收矿质元素的数量随施肥t的增加而提高，但超过一定量时，离子载体与矿质离子结合达到饱和，根系吸收矿质离子不再增加。祁门茶叶研究所多年研究表明:梅5()0克氮可收获鲜叶25千克左右.亩产鲜叶一吨左右.年施氮以20一30千克为宜.超过30千克，虽能提高产量.但利用率不高。③土城沮度:根系吸收矿质随土沮升高而加快，以25一30℃为宜。沮度过高或过低都抑制根系对矿质元素的吸收。④土坡pH:宜茶的土城pH为4.5一6.5，以pHS.2一5.6最好。一般说来，阳离子的吸收随上坡pH上升而增加，阴离子的吸收随pH的上升而降低。
