Effects of Biogas Slurry Compound Biofertilizer on Tomato Growth and Soil Fertility in Greenhouse
摘要
Abstract
[Objective] In order to improve soil fertility and agriculture yield in greenhouse.[Method] A field experiment was conducted to investigate the plant height, stem diameter, leaf number of tomato and soil fertility by applying different type of fertilizers ( BF-biogas slurry compound biofertilizer, NF-full nutrition fertilizers and CF-conventional fertilization) in Helan area of Yinchuan City.[Result] Biogas slurry compound biofertilizer significantly enhanced plant height, stem diameter and leaf number by 32.2％ ～50.7％ in tomato blooming stage, while increased by 23.3％ ～46.1％ in tomato early fruit stage compared with the control treatment.Soil organic matter was increased by 56.9％ compared with the control.Total N and total P increased stably.Compared with BF treatment,since soil available phosphorus and available potassium contents excess increased by 203.0％ and 50.0％ in conventional fertilization treatment, CF might increase nutrient leaching of the soil.Using biogas slurry compound biofertilizer, tomato growth indexes were significantly correlated with soil alkali-hydrolyzale nitrogen and organic matter contents (P<0.01), while no significant correlation was found between tomato growth indexes and soil nutrient contents in the conventional fertilization treatment.[Conclusion] Biogas slurry compound biofertilizer was more efficient in tomato growth and soil fertility improvement than other fertilizers in greenhouse.关键词
