【摘要】：本试验以炉渣资源化利用技术研发为目的,分析了炉渣、草炭、羊粪容重、总孔隙度、pH值、EC值、速效氮、速效磷、速效钾等理化性质,以炉渣、草炭、羊粪为原料基质,按不同体积比组成复合基质,配成基质中按每300mL配成基质中加4g撒可富复合肥,以内蒙古蒙肥生物科技有限公司商品育苗基质为对照,进行了黄瓜育苗试验,其试验结果如下:T1、T2、T3、T4、T5、T6、T7、CK的理化性质均在蔬菜育苗基质所要求的适宜范围内。T1、T2、T3、T4配比基质由于炉渣的比例较大,导致其容重、孔隙度等物理性质较差,保水保肥能力较差。T5的物理性质次于CK,养分含量方面高于CK,一叶一心、三叶一心时期的形态和生理指标优于CK。T6的容重与CK无显著性差异,总孔隙度低于CK,养分含量方面高于CK,一叶一心、三叶一心时期的各项形态和生理指标都优于CK。T7的物理性质次于CK,养分含量方面高于CK,一叶一心、三叶一心时期的形的各项指标部分高于CK,部分低于CK。综合来看配成基质T5(炉:羊:草=1:1:1)、T6(炉:羊:草=1:1.5:1)表现最好,尤其是T6不仅可以有效地提高黄瓜秧苗质量、培育壮苗,还可以减少草炭的用量,从而替代草炭进行黄瓜穴盘育苗,降低育苗成本,提高黄瓜穴盘育苗的经济效益。
[Abstract]:The purpose of this experiment was to research and develop the technology for the utilization of slag. The physical and chemical properties of slag, peat, sheep manure bulk density, total porosity, pH value, EC value, available nitrogen, available phosphorus and potassium were analyzed. The raw materials were slag, peat and sheep dung. The experiment of cucumber seedling breeding was carried out, which was composed of composite substrate with different volume ratio, and mixed with 4 g sack-rich compound fertilizer per 300mL. The commercial seedling raising substrate of Inner Mongolia Mongolian Fertilizer Biotechnology Co., Ltd was used as the control. The results are as follows: the physicochemical properties of T1OT2T2T3OT4T5T6T6T7 CK are within the suitable range required by vegetable seedling substrate. The physical properties such as bulk density, porosity and other physical properties of T1T2T2T3T4 matrix are poor due to the large proportion of slag. The physical properties of T5 were higher than that of CK, in nutrient content, and the morphological and physiological indexes of three leaves were better than that of CK.T6 and CK. The total porosity of CK, was higher than that of CK, in nutrient content, and the physical properties of CK.T7 were superior to those of CK, and the physical properties of trifoliate were higher than that of CK,. The indexes of trilobes were higher than CK, and lower than CK.. On the whole, T5 (furnace: sheep: grass = 1:1:1) and T6 (oven: sheep: grass = 1: 1.5: 1) performed best, especially T6 can not only effectively improve the quality of cucumber seedlings, cultivate strong seedlings, but also reduce the amount of peat, so as to replace peat for cucumber seedlings. To reduce the cost of seedling raising and to improve the economic benefit of seedling raising of cucumber.
