Effects Of Organic Fertilizer Made By Tobacco Waste On Soil Fertility And Grain Yield And Quality Of Maize,Red Bayberry And Vegetables

In recent years,due to the heavy use of chemical fertilizer,unscientific farming practices and serious shortage of organic fertilizer application resulted in unbalanced soil nutrient.The decrease of water,fertilizer and air permeability aggravated the deterioration of soil physical properties.As a result,the quality of farmland was decreased and the yield and quality of crops were greatly reduced.Chinese tobacco production has top priority in the world's and the cultivation of tobacco and its products play an important role in the development of national economy.Tobacco planting produces large amounts of waste tobacco powder which itself contains a lot of organic matter and trace elements.because of the low cost,it is very suitable for high quality organic fertilizer.It is waste of resources that untreated tobacco waste was abandoned in the field,and it was also polluted the agricultural ecological environment.So,it is necessary to treat harmlessly and utilize these wastes as an organic source.In this experiment,the organic fertilizer was produced by the waste tobacco.It was made by tobacco companies.Set up 4 kinds of fertilization treatment to study the effect of fertilization treatments(Blank control,CK treatment;chemical fertilizer treatment,CF treatment;organic manure treatment,TOF treatment;chemical fertilizer and organic manure,CF+TOF treatment).The aim was to study the effect of organic fertilizer on soil nutrients,microbial biomass,soil enzyme activity and yield and quality of maize,red bayberry,cauliflower and pepper.The main results are as follows:1.The effect of tobacco organic fertilizer and chemical fertilizer was similar to ordinary commercial organic fertilizer and chemical fertilizer.The results showed that soil available nitrogen,phosphorus,and potassium were highest in jointing,booting,and maturing stages of red bayberry?pepper?cauliflower and corn,which synchronized with the plant nutrient requirement.2.Compared to CK and CF,soil microbial biomass carbon and nitrogen were increased by both CF+TOF and TOF,indicating the stimulation of TOF on the growth and reproduction of microbes that led to the increment of microbial numbers.So as to accelerate the process of soil carbon and nitrogen cycling and the mineralization process of soil minerals.3.In CF+TOF and TOF treatment,enzyme activities in soil including sucrose,urease,phosphatase,and catalase were increased.And it is being beneficial to organic matter recycle,nitrogen and phosphorus transformation,and active oxygen elimination.As cauliflower curd growth period prolonged and soil enzyme activities increased,which might result from the increment of microbial numbers and microbial activity.4.CF+TOF treatment increased corn yield by 10.11%,crude protein by 13.94%,and starch by 13.75%.And increased cauliflower yield by 15.57%,crude protein by 24.55%,and starch by 23.51%.And CF+TOF treatment increased pepper yield by 14.04%,vitamin C by 38.36%,nitrates by 13.76%,also increased red bayberry yield by 5.45%,vitamin C by 4.77%,compared to CF.In general,because the tobacco organic fertilizer has high efficiency,high utilization rate,easy to collection and low cost,it can be a good organic fertilizer.Application of TOF in combination with CF could improve soil nutrient supplies,promote soil microbial growth and reproduction,stimulate soil enzyme activities,and increase corn?red bayberry?cauliflower and pepper yield and quality.Because our country implements the policy of green sustainable farmland,high standard farmland and tobacco control,tobacco organic fertilizer can be widely popularized and applied.
