初步研究了营养土理化条件及肥料 3要素的比例对香蕉组培袋苗 (以下简称袋苗 )生长的影响。试验结果表明 :袋苗需要较为湿润的土壤条件 ,最适宜的土壤含水量为其田间持水量的 60 %～ 80 % ;土壤质地对袋苗生长有极显著的影响 ,袋苗生长最适宜的土壤质地为中壤至重壤 ;最宜袋苗生长的土壤 pH为 6 .5左右 ,袋苗在pH 6.5～ 7.0范围内生长良好 ,pH <5.5或 pH >7.5时 ,其生长均受抑制 ;N、P素对袋苗生长的影响极显著 ,最宜的N、P、K比例为N∶P2 O5 ∶K2 O =1∶0 .2∶0 .6～1 .1。
The effects of the physical and chemical conditions of nutritive soil and the ratio of 3 fertilizers on the growth of banana seedling bags (hereinafter referred to as bags) were studied. The results showed that: the bags need more humid soil conditions, the most suitable soil moisture content of 60% to 80% of its field capacity; soil texture has a very significant impact on the growth of bags, bagging the most suitable soil The soil texture was mid-soil to heavy-paddy soil. The optimum pH of the bag-growing soil was about 6.5, the growth of the bag was good in the range of pH 6.5-7.0. The growth of the bag was inhibited when pH <5.5 or pH 7.5. , The effect of P on the growth of bagged seedlings was very significant. The optimum proportion of N, P and K was N: P2 O5: K2O = 1: 0.2: 0.6: 1.
