我区历年秋玉米是利用畬地来种植,为了避免秋旱的影响,一般是在大暑前后、立秋前播种。而立秋后八月下旬利用有灌溉条件的畬地和稻田来种秋玉米(以下简称晚田玉米)很少见,笔者根据玉米比水稻耐寒,和我区秋后气候温凉、光照充足的特点,设想种植晚秋田玉米,在水肥管理较好的情况下,可能获得较好的收成,因此,从1977年至1981年连续进行了五年晚秋田玉米的栽培试验观察,取得了初步的结果。这对于改革耕作制度,充分利用气候资源,提高粮食产量是有意义的。 一、试验情况 对于晚秋田玉米的试验观察,1977—1979年是在本站进行小面积的试验,发现每
Autumn is the use of corn in my region to plant the use of She, in order to avoid the impact of autumn drought, generally before and after the summer, sown before autumn. However, it is very rare to use the irrigated She and paddy fields to plant autumn corn (hereinafter referred to as “Yandian” corn) in late August after autumn. According to the fact that corn is more tolerant to cold than rice, It is envisaged that the cultivation of late-autumn corn can achieve better harvest under the condition of better water and fertilizer management. Therefore, from 1977 to 1981, the cultivation experiment of late autumn Akita corn was carried out continuously and the preliminary results were obtained. This is meaningful for reforming the farming system, making full use of climate resources and increasing food production. First, the test conditions Late autumn Akita corn experimental observations, 1977-1979 is a small area of the site test and found that each
