Abstract
t [Objective] The aim was to explore the effects of biogas fertilizer on occurrence rates of disease and pest damages,yield and sweetness of watermelon in seedling period.[Method] A single-factor design of experiment was conducted,involving three treatments and three repetitions.In addition,every experimental plot is 20 m2 and both of base fertilizer and top dressing were fixed.Hence,the occurrence rates of disease and pest damages,yield and sweetness of watermelon can be measured during seedling period,accordingly.[Result] The occurrence rates of diseases,such as anthracnose and epidemic disease,and pest damages,such as aphid and Aulacophora femoralis were 1.01％ and 1.41％,2.30％ and 5.72％,and 3.15％ and 10.38％ after biogas manure,cake fertilizer and chemical fertilizer were applied during seedling period.The yields were 41 925.00,37 250.25 and 36 500.25 ky per hectare,and sweetnesses were 11.15％,11.05％ and 10.40％ of watermelon applied by biogas manure,cake fertilizer and chemical fertilizer.[Conclusion] The application of biogas fertilizer would reduce occurrence rates of disease and pest damages,and improve yield and sweetness of watermelon,accordingly.关键词
