本试验在1988年试验研究和调查的基础上,1989年在武清、宝坻,利用组合技术进行了多点试验示范,总面积为345亩。其中重茬瓜地和隔年瓜地280亩,占总面积的81％。通过试验示范,以求验证组合技术的防病增产效果;调查研究不同西瓜品种及各项栽培技术克服连作障碍的有效性,为综合治理提供依据。一、试验材料和方法 1.组合技术试验示范,采用杀菌剂、土壤改良剂、营养和微量元素组合的配方。试验设2次重复,以多菌灵和不施药者(清水)为对照。示范地未设重复和对照,仅供
Based on the experimental studies and surveys conducted in 1988, this experiment was conducted in Wuqing and Baodi in 1989 with a total of 345 mu of land using a combination of technologies. One heavy melon and another melon to 280 acres, 81% of the total area. Through experiments and demonstration, in order to verify the combinatorial technology of disease prevention and increase yield; investigation of different watermelon varieties and cultivation techniques to overcome the succession obstacle effectiveness, provide the basis for comprehensive management. First, the test materials and methods 1. Combination of technology test demonstration, the use of fungicides, soil amendments, nutrition and trace elements combination of formulations. The experiment was repeated 2 times to carbendazim and non-applicants (water) as a control. No duplicates and controls are provided for demonstration purposes only
