Organic Fertilizer On Tomato Yield, Quality And Soil Fertility Effects Study

Organic manure is effective, people ask for high-quality and safe vegetable at present. On this situation, this dissertation has a research about the effect of organic manure on tomato output in a greenhouse through quadratic rotational combination design. There are three factors, such as chicken manure, pig manure and deer manure. At last, The best product model of yield tomato using organic manure is found. This dissertation also analyses the influence of organic manure for growth and quality of tomato, soil nutrient and microbe in potted plant experiment, in order to provide theoretical and realistic basis for producing safe and high-quality vegetables.Analyzing the optimized model, I draw on a conclusion in the condition of the experiment. The result shows that the highest output of tomato is 12372kg/1000m2. In this level, the scheme of using manure is that chicken manure is 2218.28 kg/1000m2,pig manure is 5959.54 kg/1000m2, deer manure is 1910.08 kg/1000m2. Adopting single manure, their output has obvious difference. Their output from high to low is: chicken manure >deer manure >pig manure. The proper quantity of chicken manure is 3063.54 kg/1000m2. That of deer manure is 2880.91 kg/1000m2. And thatof pig manure is 6235.77 kg/1000m2 . If the chicken manure and deer manure were superfluous, the output would be restrained. But as for pig manure, the output couldn't be restrained though it is superfluous.It is also found that applying organic manure in the soil can promote the growth of tomato in potted plant. The growth is preferable when the percent of chicken manure is 1.2%, pig manure is 1.2%, deer manure is 1.2% and corn stalk is 0.8%.Organic manure can promote soluble sugar content of tomato. The soluble sugar content of tomato is preferable when the percent of chicken feces is 1.2%, pig manure is 1.2%, deer manure is 1.2% and corn stalk is 0.8%. Their soluble sugar content is respective 3.27%, 3.13%, 3.05% and 2.92%,, Soluble sugar content from high to low is: corn stalk>chicken manure >pig manure >deer manure.Organic manure can promote tomato vitamin c content. The vitamin c content is preferable when the percent of chicken manure is 1.2%; pig manure is 1.2%, deer manure is 1.2% and corn stalk is 0.8%. Their vitamin c content is respective11.83mg/100g, 11.52mg/100g, 11.42 mg/100g and 10.71 mg/100g. Vitamin c content is: corn stalk> chicken manure > pig manure > deer manure.Organic manure can reduce nitrate content of tomato. Nitrate content of the treatment that the percent of manure is 1.2% is lower in the same organic manure. Nitrate content of 1.2% corn stalk, chicken manure, pig manure and deer manure is respective 80.22mg/kg, 89.16mg/kg, 100.81mg/kg and 75.19mg/kg. Nitrate content from low to high is: deer manure 1.2% pig manure=1.2% corn stalk>l .2% deer manure. The amount of bacteria in the soil from high to low is: 1.2% corn stall>1.2% chicken manure >1.2% pig manure >1.2% deer manure. The amount of fungi in the soil from high to low is: 1.2% corn stalk>1.2% chicken manure >1.2% pig manure >1.2% deer manure. The amount of ammonifying bacteria in the soil from high to low is: 1.2% corn stall>1.2% chicken manure >1.2% pig manure >1.2% deer manure.Organic manure has an important role in the production of vegetables.
