Effect of Different Fertilizer Combinations on Yield and Quality of Tomato in Greenhouse

Taking‘Fentailang'tomato as material and no fertilizer as control,the micro area test was adopted,and the effect of manuring late to tomato on the volume of production and quality were studied,which takes chicken manure(M) as basic fertilizer and combines with straw(R),potassium(K)and calcium(Ca)in different ways.The results showed that the combination of chicken manure and potassium sulfate(MK)led to the highest production,single fruit weight,fruit diameter,vitamin C content and organic acid content,what's more,vitamin C content,soluble sugar,organic acid and soluble solid content,which increased by 28.83%,8.80%,47.22% and 8.05% respectively compared with chicken manure(M).The soluble sugar,soluble solid content reached the highest,the content of vitamin C,soluble sugar,organic acid and soluble solid content increased by 18.66%,8.09%,22.22%,and 17.24% when processed by chicken manure and calcium hydroxide combination(MCa)compared with chicken manure(M).The combination of chicken manure and straw(MR)led to the lowest organic acid,it was significantly.It was thus clear that the combination of chicken manure,straw,calcium hydroxide and potassium fertilizer treatment improved the quality but didn't have significant positive effects.Hence,both yield and quality benefits could be satisfied by MK.
