摘要
试验研究几种人工合成土壤理化性质及其对番茄生长发育和产量的影响结果表明,生活垃圾、羊粪、玉米秸秆、糠醛渣、肥沃土壤按容积比0.20∶0.15∶0.15∶0.10∶0.40,并加入酵素菌速腐剂、番茄专用肥发酵处理后配制成人工合成土壤有利于番茄生长发育。与传统土壤栽培(对照)相比,其土壤容重降低0.31g/cm3,总孔隙度、毛管孔隙度、空气孔隙度分别增加11.71%、6.12%和5.59%;自然含水量、容积含水量、水层厚度、蓄水量分别增加106.93g/kg、6.12%、12.24mm和122.46m3/hm2;有机质、速效氮、速效磷、速效钾、阳离子交换量分别增加16.70g/kg、29.97mg/kg、11.37mg/kg、35.25mg/kg及5.73cmol/kg;番茄株高、茎粗、单果重、单株果重、产量、产值、利润分别增加36.16cm、0.50cm、33.30g、0.97kg/株、36.30t/hm2、2.18万元/hm2和1.07万元/hm2,并有明显减缓重金属元素Hg、Cd、Cr和Pb富集趋势。
The physical and chemical characters of some kinds of artificial synthetic soil and their influence on the growth and output of tomato were studied. The results show that the volume ratio of rubbish lives, sheep dung, corn straw,chaff quan dregs and rich soil is 0.20：0.15：0.15：0.10：0.40 ,joining quickly stale dose of ferment bacterium and the tomato fertilizer for special purpose, ferment to handle the rear artificial synthetic soil of compounding. It is helpful for tomato growth. Comparing with traditional soil culture（CK）,soil bulk density reduces 0.31g/cm^3, total porosity, woollen pipe porosity and air porosity increase 11.71%, 6.12 % and 5.59 % respectively; naturally water content, volume water content, water layer thickness and reservoir storage increase 106.93g/kg, 6.12 %, 12.24ram and 122.46m3/hm^2 ; organic matter, available N, available P, available K and cation exchange capacity increase 16.70g/kg, 29.97mg/kg, 11.37mg/kg, 35.25mg/kg and 5.73cmol/kg; the height,diameter, one fruit weight, fruit weight per plant,output,output value and profit of tomato in crease 36.16cm, 0.50cm, 33.30g, 0.97kg/plant, 36.30t/hm^2, 21.8 thousand yuan/hm^2, 10.7thousand yuan/hm^2. And for the element Hg, Cd,Cr and Pb of heavy metal,the enrichments have obvious slow down tendency.
