1990年滑县县委、县政府组织22个乡镇,对30万亩夏玉米进行高产开发,经县高产开发指挥部验收,平均亩产566公斤。有165块高产田,面积1007.3亩,平均亩产650公斤以上。枣村乡西莹村唐福吾种植的一亩掖单13,亩产达906公斤。在开发方的带动下,全县53.6万亩夏玉米平均亩产370公斤。高产开发田普遍实行麦垄套种,主要抓了四项关键技术措施。一、扩大种植良种,改平展叶型为竖叶型玉米品种。开发方种植竖叶型玉米品种面积占70%以上,竖叶型品种上部叶片上冲,叶相直立,夹角较小,有利于光的投射,植株冠层形成了良好的透光层,提
In 1990, Huaxian county party committee and county government organized 22 towns and villages to carry out high-yield development on 300,000 mu of summer maize. The county passed the high-yield development headquarters inspection and acceptance, with an average yield of 566 kg per mu. There are 165 high-yield fields with an area of 1007.3 mu and an average yield of 650 kg per mu. Jujube village Xi Yingcun Tang Fu Wu planted a Yedian 13, 906 kilograms per mu. Driven by the development side, the county 536,000 mu of summer maize average yield 370 kilograms. Wheat cultivation is widely practiced in high-yield fields, mainly focusing on four key technical measures. First, expand the planting of seeds, flattening leaves for vertical leaf corn varieties. The planting area occupied more than 70% of the cultivars with vertical leaves, and the upper leaves of the vertical leaves had the shape of upright leaves and the leaves were upright and the included angle was small, which was in favor of light projection. The plant canopies formed a good light transmission layer
