Abstract:

It was used to improved soil for culture of the old grapes more than 10 years in plastic greenhouses with the tea dregs organic and inorganic fertilizer including activity microbe (simple name Tea dregs Fertilizer, TF, the same below). The results showed that the grape color up as early as 1-2 days than general fertilizer methods (as Check) with TF. There was a trends of reduce in diseases and pests, and improving in the appearance quality of grapes. The soluble solid of greenhouse grape was positively correlated with TF content and pulp hardness, viscosity was almost parabola correlated with TF contents. It can increase weight of grape ear and grains , and thus increase yields and income under the premise of ear number in grapes. It is the best amount of fertilizer using 2250kg/hm2 according to the production traits, quality traits and economic factors of the greenhouse grape.
