系统研究了几种合成有机土壤的理化性质及其对茄子生长发育和产量的影响。结果表明:人工合成有机土壤A组合,生活垃圾、羊粪、玉米秸、菜籽饼、粉煤灰及肥沃土壤容积比为0.20∶0.20∶0.10∶0.03∶0.07∶0.40,加入茄子专用肥发酵处理后,配制成人工合成有机土壤有利于茄子的生长发育。与对照(土壤栽培)比较,容重降低0.31g cm-3,总孔度、毛管孔度、空气孔度分别增加11.71%、4.80%和6.91%;自然含水量、蓄水量分别增加104.67g kg-1和94.93m3hm-2;有机质、速效N、P、K、CEC分别增加14.00 g kg-1、24.73mg kg-1、11.83 mg kg-1、42.91 mg kg-1和5.68 cmol kg-1;重金属离子Hg、Cd、Cr、Pb分别降低0.02 mg kg-1、0.03 mg kg-1、0.32 mg kg-1、0.54 mg kg-1;茄子株高、茎粗、单果重、单株果重、产量、产值、利润分别增加19.57 cm、0.34 cm、74.58g、0.55kg、19.01 t hm-2、1.63万元hm-2和1.05万元hm-2。不同处理间的差异显著性经LSR检验达到显著和极显著水平。
The physicochemical properties of several synthetic organic soils and their effects on the growth and yield of eggplant were studied systematically. The results showed that: A combination of synthetic organic soil, domestic waste, sheep manure, corn stalks, rapeseed cake, fly ash and fertile soil volume ratio of 0.20:0.20:0.10:0.03:0.07:0.40, adding eggplant special fertilizer fermentation After the preparation of artificial synthetic organic soil is conducive to the growth and development of eggplant. Compared with the control (soil culture), the bulk density decreased by 0.31g cm-3, and the total porosity, capillary porosity and air porosity increased by 11.71%, 4.80% and 6.91% respectively. The natural water content and water storage capacity increased by 104.67g kg -1 and 94.93m3hm-2 respectively. The contents of organic matter, available N, P, K and CEC increased 14.00 g kg-1, 24.73 mg kg-1, 11.83 mg kg-1 and 42.91 mg kg-1 and 5.68 cmol kg- The contents of Hg, Cd, Cr and Pb in heavy metals decreased by 0.02 mg kg-1, 0.03 mg kg-1, 0.32 mg kg-1 and 0.54 mg kg-1, respectively. Output, output value and profit increased by 19.57 cm, 0.34 cm, 74.58g, 0.55kg, 19.01 t hm-2, 16,300 yuan hm-2 and 10,500 yuan hm-2 respectively. Significant differences between the different treatments by the LSR test to reach significant and extremely significant level.
