The Effect Of Manure On Greenhouse Tomato

The change of c organic manure compost and the effect of organic manure on physical character, chemical character and biological character in soil were studied,and analysised the effect of organic manure on tomato yield and quality .The main results is as follows:1. The organic manure joined with corn straw during composting decreased the decrement of N , increase N, P, K content of compost. after decomposting , the organic matter increase too. The chicken manure joined with 6% corn straw during decomposting is preferable , the nutrient of compost is the highest .Applying organic manure in soil can better physical character, chemical character in soil. The chicken manure , pig manure and corn straw can increase organic matter in soil, decrease volume weight of soil, improve total porosity . Chicken manure joined with0.8% fresh corn straw is the best treatment. The organic manure can bring down the content of EC and PH in soil, and restrain soil salinization and acidation .Chicken manure joined with 6% rotted corn straw is the best treatment.Applying organic manure in soil can increase the amount of bacteria , actinemyces, fungi and ammonifying bacteria. It also can increase B/P in soil , improve the resistivity germ of soil. The result showed chicken manure joined with 9% rotted corn straw and 0.8% fresh corn straw are better treatments.The highest yield of 14359.48 kg1000m-2 is the treatment of chicken manure joined with 6% rotted corn straw. The chicken manure joined with 0.8% fresh corn straw is 13076.37 kg/1000 m-2. Yield of applying chicken manure joined with rotted corn straw treatments are higher than chicken manure joined with fresh corn straw.Organic manure can promote the content soluble sugar and organic acid of tomato , increase T/S of tomato .It also can increase vitamin C of tomato and decrease nitrate content of tomato. Chicken manure joined with 9% rotted corn straw is the best treatment towards improving the quality of tomato.All in all, organic manure played an important role in the production of vegetables.
