玉米是本省夏秋季栽培的主要粮食作物之一。在本省山区及半山区的旱地和丘陵河谷地带等秋季水利条件较差、不宜于种植水稻的水田,栽培玉米可以获得较为稳定的产量。历年来,本省不少地区更出现了较大面积的丰产事例,如1960年淳安县6万余亩秋玉米,虽遇夏秋雨涝,平均亩产仍达到231斤;1961年东阳县27万余亩玉米,虽遇严重夏秋长期干旱,平均亩产也达到280斤以上。栽培有经验的东阳县安文区道士岙大队,1961年192亩秋玉米,平均亩产达到480斤;其中1.66亩丰产田,平均亩产高达791斤。因此,认真总结几年来各地玉米增产的技术经验,提供生产上参考采用,对提高玉米单位面积产量,具有重要的意义。
Corn is one of the main food crops cultivated in summer and autumn in this province. In the mountainous and semi-mountainous areas of dry land and hilly valleys and other autumn water conditions are poor, not suitable for planting paddy fields, cultivation of corn can get more stable output. In recent years, many areas in our province have even seen examples of large-area high yield. For example, in 1960, more than 60,000 mu of autumn corn were used in Chun’an County. Although the average yield per mu of summer corn dropped to 231 kg in summer and autumn, 270,000 in Dongyang County in 1961 The remaining acres of corn, although a serious summer drought, the average yield has reached more than 280 pounds. Cultivation of Dongyang County, Anwen District Taoist 岙 brigade, 1961 acres of autumn corn, the average yield reached 480 pounds; of which 1.66 acres of high yielding fields, the average yield of up to 791 pounds. Therefore, it is of great significance to conscientiously summarize the technical experience of increasing corn production over the past few years, and to provide a reference to the production for use in improving yield per unit area of corn.
