为使地处北纬47°34′～48°18′,东经126°01′～126°41′,年无霜在105～115天的地带,创出一条种植业高效益渠道,引入南瓜进行栽培。我们面对当前南瓜籽生产上存在的品种混杂,管理粗放,病虫害日趋严重的问题,利用北寒带适合南瓜栽培的物候特点和土壤条件,在提高南瓜籽产量上,经过实践,探讨出了以下技术措施。1 选地、选茬、整地施肥南瓜忌重茬,与瓜类蔬菜实行两年轮作,前茬最好是谷子、糜子,其次是豆茬。要选择排水良好的平
In order to make it located at a latitude of 47 ° 34 ’~ 48 ° 18’ and an interval of 126 ° 01 ’~ 126 ° 41’ east longitude and with no frost in the region of 105 ~ 115 days, it will create a high-efficient cultivation channel and introduce pumpkin for cultivation . We face the current production of pumpkin seeds exist in the variety of mixed, extensive management, pests and diseases are increasingly serious problem, the use of the North boreal suitable for pumpkin cultivation of phenological characteristics and soil conditions, to improve pumpkin seed production, through practice, to explore the following technologies Measures. 1 election, cropping, land preparation and fertilization pumpkin bogey crop, and melon vegetables two years of rotation, the best is the millet before the stubble, millet, followed by the stubble. To choose a good drainage flat
