育苗基质不同施肥量对茄果类蔬菜幼苗生长的影响

运用正交试验设计 ,在以草炭、蛭石、珍珠岩为原料的育苗基层中 ,加入不同浓度的氮、磷、钾肥料 ,对番茄、茄子和甜椒幼苗生长的影响进行了研究。结果表明 ,不同肥料品种与施肥量对茄果类蔬菜幼苗生长的影响具有显著差异 ,特别是增施磷肥可使幼苗株高和干物重增加 ,其相关性达到显著或极显著水平 ,是培育优质壮苗的重要营养元素 ;同时 ,要注意氮、磷、钾肥料配合使用 ,以提高壮苗水平。供试育苗基质的最佳N、P2 O5、K2 O施肥量分别为 :番茄 0 .2kg/m3、0 .4kg/m3、0 .2kg/m3,茄子 0 .8kg/m3、0 .4kg/m3、0 .2kg/m3,甜椒 0 .4kg/m3、0 .4kg/m3、0 .4kg/m3。

Effects of Different Amount of Fertilizer Applied in Nursing Media on the Growth of Solanaceous Fruits Seedlings

Study the effect of applying different concentration nitrogen?phosphorus?potassium fertilizers to nursing media consisted of turf?vermiculite and perlite on the seedlings growth of Solanaceous fruits such as tomato?eggplant and sweet pepper,by using orthogonal design.The results showed that the effect of different fertilizer variety and different application amount on the growth of Solanaceous fruits seedlings is significant,especially increasing phosphorus fertilizer application can increase the seedling height and the dry matter weight ,the correlation if significant or more significant,so the phosphorus is the important nutrient element in raising sturdy seedlings;Simultaneously to increase the sturdy seedlings standard,the nitrogen?phosphourus?potassium fertilizers application should be formulated.In this experiment,the best N?P 2O 5?K 2O application amount for the nursing media was tomato 0.2 kg/m 3?0.4kg/m 3?0.2kg/m 3,eggplant 0.8kg/m 3? 0.4kg/m 3 ?0.2kg/m 3,sweet pepper 0.4kg/m 3?0.4kg/m 3?0.4kg/m 3.
