仙客来属球根花卉,对土壤要求较严。为此我们做了仙客来培养土的对比试验。选用10月播种的仙客来苗150株,11月中旬开始根外追肥(尿素0.5‰,磷酸二氢钾1‰),每周一次。来年2月上盆时,将其分成三组,分别栽于三种不同的培养土中:①炉渣:蛭石:腐叶土=1:1:2②腐叶土:细沙:马粪=2:2:1 Cyclamen is a flower bulbs, more stringent requirements on the soil. To this end, we made a cyclamen to cultivate soil contrast test. 150 plants of cyclamen were planted in October, and topdressing fertilizer (0.5 ‰ of urea and 1 ‰ of potassium dihydrogen phosphate) from the middle of November once a week. In February next year on the pot, it is divided into three groups, were planted in three different culture soil: ① slag: vermiculite: rotting soil = 1: 1: 2 ② leaf mold soil: fine sand: horse manure = 2 : 2: 1
