Research On Making Liquid Organic Fertilizer And Physical And Chemical Properties And Effects Of Growing Seedlings By Retting Tomato Straw

Through a comprehensive analysis of the tomato stalks anaerobic fermentation and aerobic fermentation retting pHysical,chemical properties of liquid organic fertilizer and tomato seedling, tomato straw retting liquid organic fertilizer to evaluate the effect of tomato stalks reasonable method retting liquid organic fertilizer quest. In this experiment, tomato straw as materials, anaerobic fermentation group(T1 group, tomato straw: water = 1g: 5mL), aerobic fermentation group(T2 group, tomato straw: water = 1g: 2mL) was treated, water for the control group(CK group), for a period of 90 days of fermentation test. Determination of fat in the preparation of organic nutrients content in each group and seedling growth of tomato seedlings morpHological and pHysiological indicators index, using Excel and DPS software for data processing, tomato straw retting liquid organic fertilizer effect a comprehensive assessment. Tests showed that the tomato stalks anaerobic fermentation liquid organic fertilizer retting total nitrogen, total pHospHorus, available nitrogen and potassium were higher than other treatments, showing a very significant difference, total potassium tomato stalks aerobic fermentation liquid organic fertilizer retting, available pHospHorus, organic matter, EC value than other treatments; tomato stalks anaerobic fermentation retting liquid organic fertilizer processing tomato seedling height, stem diameter, leaf area, shoot / lower fresh weight, ground / lower dry weight, shoot ratio, seedling index were higher than the other two groups handle. Tomato straw anaerobic fermentation retting liquid organic fertilizer is one of the better ways to tomato stalks efficient resource processing and nutrient recycling.
