盆周高山区是我省玉米主产区的一个重要组成部分,但由于热量资源不足,春秋冷害频繁,技术上没有相应的措施适应上述特点,杂交玉米的利用受到限制,玉米产量低而不稳,常年实际亩产不足200斤。针对上述问题,近年来我们把“盖膜增温”和“育苗移栽”技术应用到山区玉米栽培上取得了良好的效果。今年在巫山县海拔1,300—1,700米的
Because of insufficient heat resources and frequent cold chilling in spring and autumn, there is no corresponding technical measures to meet the above-mentioned characteristics, the utilization of hybrid maize is limited, the yield of maize is low and unsteady Annual perennial actual production of less than 200 pounds. In response to the above problems, we have achieved good results by applying the technology of “covering membrane warming” and “seedling transplanting” to the cultivation of corn in the mountains in recent years. This year in Wushan County 1,300-1,700 meters above sea level
