全营养混合基质理化性质及其对人参果生长发育和产量的影响

研究了几种全营养混合基质的理化性质及其对人参果生长发育和产量的影响,结果表明:生活垃圾、羊粪、玉米秸杆、糠醛渣、肥沃土壤,容积比为0.20∶0.15:0.15:0.10:0.40,加入酵素菌速腐剂、人参果专用肥,发酵处理后配制成全营养混合基质有利于人参果的生长发育,与对照(传统土壤栽培)比较,容重降低0.31gcm-3,总孔度、毛管孔度、空气孔度分别增加11.71%、6.12%、5.59%;自然含水量、蓄水量分别增加106.93g kg-1、122.46m3hm-2;有机质、速效N、P、K、阳离子交换量分别增加16.70 g kg-1、29.97mg kg-1、11.37 mg kg-1、35.25 mg kg-1、5.73 cmol kg-1;人参果株高、茎粗、单果重、单株果重、产量、产值、利润分别增加21.70 cm、0.55 cm、43.29g、0.59kg/株、21.78 t hm-2、4.36万元hm-2、3.25万元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 Nature of the Whole Xlatrition Matrix and its Influence on Ginseng Growth and Output

We studied the nature of some kinds of whole nutrition matrix and their influence on ginseng growth and output.The results showed that the whole nutrition matrix,which includes life rubbish,sheep dung,corn straw,furfural residue and fertile soil with the ratioof 0.20: 0.15: 0.15: 0.10: 0.40,addition of accelerant of ferment bacteria and special fertilizer for ginseng,helped the growth of ginseng.Compared with the control,except the bulk density decreased 0.31g cm~(-3),all the other parameters tested increased.The detaliled data as follows:whole porosity 11.71%,capillary pore 6.12%,air-space porosity 5.59%,natural water content 106.93g kg~(-1),water storage content 122.46m~3 ha~(-1),organic matter 16.70g kg~(-1),available N 29.97mg kg~(-1),available P 11.37mg kg~(-1),available K 35.25mg kg~(-1),CEC 5.73cmol kg~(1),the height of plant 21.70cm,diameter of stem 0.55cm,single fruit weight 43.29g,single plant fruit weight 0.59g per plant,output 21.78t hm~(-2),production value 43.6 thousand yuan hm~(-2),prolfit 32.5 thousand yuan hm~-2.The difference between the different treatments was significant or very significant.
