摘 要:通过两年的盆栽试验,考察了8种风砂土营养调理剂对白菜生长的影响.结果表明,与单施无机化肥相比,同时施用无机化肥与泥炭或腐泥或其混合物或腐植酸液体肥,白菜的生长高度、最大叶宽、鲜重和干重都得到了提高;单施无机化肥或共同施用无机化肥和腐植酸液体肥对当年白菜生长效果显著,第二年白菜生长明显下降;用泥炭、腐泥或其混合物改良风砂土后,再施用无机化肥,不仅当年作物生长好于单施无机化肥的,而且具有后效性.由此可见,有机物料泥炭、腐泥与无机化肥等制成的有机无机复合型土壤营养调理剂,具有改良土壤结构、提供营养,兼有长效与短效双重功能,是风砂土改良的最佳选择.8 kinds of soil ameliorants were applied into aeolian sandy soil in the western Jilin,Chinese cabbage was sowed in the pot filled with the treated aeolian sandy soil and the height,length of root or width of leaves,fresh weight and dry weight of Chinese cabbage in the pot were investigated.The results show that the status of Chinese cabbage in the aeolian sandy soil treated with inorganic fertilizer and liquid humic acid or peat or sapropel is better than that in the aeolian sandy soil only inorganic fertilizer was added.The Chinese cabbage grows well in first growing season and decreases in second growing season in the aeolian soils which only inorganic fertilizer or inorganic fertilizer and liquid humic acid were added into,but keep in good condition in second growing season in the aeolian soils that were treated with inorganic fertilizer and peat or sapropel or the mixture of peat-sapropel.So organic-inorganic composite ameliorants made from inorganic fertilizer and organic materials,such as peat,sapropel,or the mixture of peat-sapropel have double function of quick-acting and long lasting effects.
