西瓜是受人喜爱的夏令水果,它不仅汁多味甜,清香爽口,而且能消热解渴,是一种很好的防暑佳品。近年来上海郊区西瓜种植面积不断扩大,1985年达20万亩。随着西瓜种植面积的扩大,农村经济结构变化后农业劳动力的减少,以及饼肥、猪厩肥等优质有机肥数量的不足,广大瓜农急切地盼望研制出一种适于西瓜生长发育所需的专用复合肥料。我组自1984年起,对西瓜专用复合肥料进行了研究。西瓜专用复合肥料配方是以植物营养为基础,土壤为校正因子,其中含有西瓜生长所必需的氮磷钾和微量元素。1985年在青浦重固、沈巷、蒸淀等乡进行了田间肥效对比试验。现将初试结果总结如下。
Watermelon is a favorite summer fruit, it is not only sweet and juicy, fragrant and refreshing, but also to quench thirst heat, is a good summer sushi. In recent years, suburban areas in Shanghai continue to expand watermelon cultivation in 1985 reached 200,000 mu. With the expansion of watermelon planting area, the reduction of agricultural labor force after the change of rural economic structure, and the shortage of high-quality organic fertilizer such as cake and pig manure, the majority of melon farmers are eager to develop a special composite for watermelon growth and development fertilizer. My group since 1984, the watermelon dedicated compound fertilizer was studied. Watermelon compound fertilizer formula is based on plant nutrition, soil as a correction factor, which contains the necessary watermelon growth of nitrogen, phosphorus and potassium and trace elements. In 1985 Qingpu solid, Shen Lane, steamed and other township field fertilizer efficiency comparison test. Now the first test results are summarized below.
