以中药渣堆肥为肥源对黄瓜基质育苗的影响

Effect of Compost from Chinese Medicine Residue as Fertilizer Resource on Cucumber Seedling with Substrate

以中药渣堆肥、椰糠、蛭石、珍珠岩作为基质材料,以黄瓜出苗率,以市售商品基质作为对照(CK),以及播后35d的植株株高、茎粗、叶片数、叶面积、植株生物量(鲜重、干重)和壮苗指数作为参数,初步研究了黄瓜育苗基质中加入中药渣堆肥后的供肥效果以及对黄瓜幼苗生长情况的影响。结果表明:添加少量中药渣堆肥(T3处理)不会对黄瓜出苗率产生不利影响,但是中药渣堆肥添加量过多会对黄瓜的出苗率产生了抑制作用;从农学指标来看,与不添加中药渣的处理相比中药渣添加量为70%(V/V)(T4处理)可显著地促进黄瓜幼苗各项参数的提高,与CK相比,T4处理能够很好的满足黄瓜的生长且对黄瓜的叶片数和生物量(干重)有所提高;从壮苗指数看,加入中药渣堆肥可以很好地提高黄瓜幼苗的壮苗指数。

Using the compost made from Chinese Medicine Residue（CCMR）,coir dust,vermiculite and pearlite as substrate materials,taking the commercial substrate as control,with germination rate of cucumber,plant height,stem diameter,leaf number,leaf area,plant fresh weight,dry weight,seedling index after sowing in 35 days as parameter,the effect of CCMR on fertilizer efficiency and growth of cucumber seedling were studied.The results showed that add a few CCMR to the substrate（T3treatment）had not affect the emergence of cucumber,but the excess CCMR（T4treatment）had an adverse effect on the emergence of cucumber.In the aspect of agronomy parameter,compared with the treat without CCMR,T4 treatment with the additive amount of CCMR was 70%（V/V）could improve the parameters significantly,compared with the control,T4 treatment could meet the growth of the cucumber very well and increase the leaf number and dry weigh.In addition,the CCMR could improve the seedling index.
