A Trial of Effect of Application of Combination of Soil - Testing Composition Fertilizer with Bio - Organic Fertilizer of Luyuan Brand on Watermelon Production

The bio-organic fertilizer of Luyuan brand is a new type of pollutionfree fertilizer.The proportion of N:P_2O_5:K_2O is 10:5:5.The favorable bacteria are 20 million/g and the content of organic substance takes up 25%.A plot trial and simple comparison trial of application of combination of soil-testing composition fertilizer with bio-organic fertilizer of Luyuan brand and with application of the conventional fertilizer was conducted.The trail result showed that the application of combination of soil-testing composition fertilizer with bio-organic fertilizer of Luyuan brand achieved obvious impact on yields and quality of watermelon.Of which the yield of watermelon from the plot trial increased 2505kg/hm~2 and 2023kg/hm~2 with an income increasing 979.5 yuan/hm2.At the same time,the trial also showed that the application of combination soil-testing composition fertilizer with bio-organic fertilizer of Luyuan brand had effect on improvement of soil fertility.
