余干县华林岗乡潘家墩村,1984年栽培早稻149.3亩,1985年栽培早稻152.8亩,两年都获得了丰收。全村早稻总产量,1984年为129918斤,1985年达133029斤,两年亩产平均保持在870斤,比1983年总产分别增37618斤和40729斤。他们主要采取了下列高产栽培技术。 一、选择高产良种,实行合理轮种 过去潘家墩村一直把6044作为主栽品种,因多年种植,致使该品种原有的丰产性和抗逆性减退,早稻不能获得高产。针对这一情况,该村连续两年对早稻品种作了较大变动。1984年改种浙辐802和广陆矮四号共132亩,占早稻面积的80％以上;1985年又调种73—07品种70亩,其余面积均为浙辐802,在品种间轮作,即在同一田块内不连续两年种植同一品种。
Yugan Village, Panjiaodun Village, Yugan County, 149.3 mu of early rice cultivated in 1984 and 152.8 mu of early morning rice in 1985, both of which have achieved good harvest in the past two years. The total output of early rice in the village was 122,918 kg in 1984 and 133,029 kg in 1985, maintaining an average of 870 kg per mu in two years, 37,618 kg and 40,729 kg more than the total output in 1983 respectively. They mainly adopt the following high-yielding cultivation techniques. First, the choice of high-yielding seeds, the implementation of a reasonable rotation In the past Panjiaodun 6044 as the main varieties have been cultivated for many years, resulting in the original varieties of high yield and resistance decline, early rice can not get high yield. In response to this situation, the village for two consecutive years made a big change in early rice varieties. In 1984, a total of 132 hectares of Zhefu 802 and Guanglu Dwarf were rebuilt, accounting for more than 80% of the area of early rice. In 1985, another 70 hectares of 73-07 were planted, with the remaining area being Zhefu 802, That is not the same field within two consecutive years of planting the same species.
