地瓜是我区的主要粮食作物之一。为了夺取地瓜高产,我们自1973年开始对春地瓜的高产规律与栽培措施进行研究,至1977年本所与基点、协作点共试验82处次,其中高产的有52处次,共计116.3亩,亩产7078—9064斤,並在小面积上突破万斤。通过研究看出,改良土壤、增强土壤通气性,增施肥料、合理施肥,选用良种、壮苗,合理密植,及时排涝、防旱等措施,能够促进前期早发,控制中期徒长,防止后期早衰而获得
Sweet potatoes are one of the main food crops in our district. In order to seize the high yield of sweet potatoes, we began to study the law of high yield and cultivation measures of spring sweet potatoes since 1973. By 1977, our institute had conducted 82 times of cooperation with the basic points and cooperation points, of which 52 were high-yielding with a total of 116.3 mu, 7078-9064 kg per mu, and in a small area exceeded million pounds. Through the research, it can be seen that improving the soil, enhancing soil aeration, increasing fertilizers, fertilizing rationally, selecting good seedlings, strong seedlings, reasonably planting densely, timely draining water and preventing drought can promote the early onset of early onset, And get
