富钾绿肥植物的筛选及应用

The Screening and Applixation of Green Manure Plant of Rich Potassium

通过对 5种富钾植物盆栽试验 ,探索土壤中钾素含量、土壤肥力及难溶性钾矿物与这些富钾植物体含钾量的关系 ,并从中选择富钾植物青厢进行大田试验 ,为合理利用生物钾肥。

Through the pot experiments of five kinds of plants of rich potassium,the authors investigated the potassium in the soil,the soil fertility and the relationship between the hard dissolved potassium mineral and the potassium content of the mentioned rich potassium plants By this way the rich potassium plant,feather cockscomb,was chosen for field experiment Thus a new way of the reasonable utilization of bio-potassium fertilizer and the raising up of land fertility was brought forward
