笔者经多年试验摸索出一整套春马铃薯与西瓜间套复种新技术,取得了显著成效。1994年,在长荡、黄尖等乡镇示范推广的13hm~2复种田,每667m~2产值逾3000元(春马铃薯2000kg×0.60元/kg、西瓜3600kg×0.52元/kg),已成为当今调优种植结构、发展高效农业的一种较为理想的推广模式。1注重选种育苗 春马铃薯选用株型紧凑、生育期短的“东农303”、“克新四号”等早熟高产良种。播前一个月再选
After years of testing, the author worked out a set of new technologies for multiple cropping between spring potatoes and watermelons and achieved remarkable results. In 1994, 13hm ~ 2 re-farming in villages and towns such as Cheongang and Huangjian showed that the output value per mu of 667m ~ 2 was more than 3000 yuan (2000kg × 0.60 yuan / kg for spring potato and 3600kg × 0.52 yuan / kg for watermelon) Adjust the planting structure, the development of efficient agriculture is a more ideal mode of promotion. 1 pay attention to the selection of seedling spring potato selection plant compact, short growth period “Dongnong 303”, “g new No. 4” and other early maturing high yielding varieties.
