The Value of Ci of leaf in Rain cultivation is less than in Open-air cultivation.The content of chlorophyl a and b of Rosario Bianco leaf in Rain cultivation is higher than in Open-air cultivation and the chlorophyl content of the 5th leaf is maximal in Rain cultivation. Stem diameter of Rosario Bianco were increased 8.68%~10.74% during the stage of rain growth in Rain cultivation. The study shows the leaf area of Rosario Bianco in greenhouse is lager than unsheltered and the environment of greenhouse is suit for grape leaf growing.

In this paper, 1554 strains of bacteria were isolated from the soybean rhizophere in the different continuous systems. Those biocontrol bacteria were screened in vitro and in vivo. 6 strains of them had the better control efficacy. They exhibited the different antagonism to the pathogens of soybean root in vitro. The strains 18BR2-2 and 18BR9-1 showed a wide range of antagonism against Fusarium oxysporum, F. avenaoeum, F. solani and Rhizoctonia solani in vitro. The 6 strains exhibited different control efficacy to soybean root rot in greenhouse and in field. In greenhouse, they could decrease the degree of soybean disease significantly, and the control efficacy of 18BR2-2 was the best and can reach 45.90%. In theory, soybean treated by 18BR2-2 may postpone the days of outbreaking of disease for 6 days. The strain 18BR2-2 also promoted the growth of soybean seedling and, raising the soybean height for 11.24%, increasing dry weight for 40.91% and fresh weight for 35.27%.
