涿鹿县郭庄乡把轮作当作建设稳产高产田的一项常规技术常抓不懈。在8000亩中低产田上实行水稻与玉米、小麦一年一轮作或两年一轮作。不要什么投入,就收到了显著的增产效果。1991年栽植4000亩水稻平均亩产500公斤,总产221万公斤。4000亩玉米、小麦套种田亩产800公斤,总产320万公斤。我乡地处官厅湖上游,有耕地18288亩。由于地势低洼,官厅湖水的浸没,渍涝盐碱地占总耕地的近一半。成为建设吨粮田的拉腿田。我们继承和发展了传统的水旱轮作技术。统一调整种植结构,使轮作面积扩大到1万亩,中产田实行两年一轮作,低产田实
Zhuolu County, Zhuo Township, the rotation as a steady production of high-yielding fields of a conventional technology often perseverance. In 8,000 acres of low-yielding fields on the implementation of rice and corn, wheat a year or two for a round. Do not invest anything, they received a significant increase in production. In 1991, the average mu yield of 4000 mu rice was 500 kg, with a total output of 2.21 million kg. 4000 mu of corn, 800 mu of wheat and 800 mu of farm produce with a total output of 3.2 million kilograms. Township is located in the upper reaches of Guanting Lake, 18288 acres of arable land. Due to the low-lying, Guanting Lake immersion, waterlogging saline land accounted for nearly half of the total arable land. As the construction of tons of grain leg fields. We inherit and develop the traditional water and drought rotation technology. Unified adjustment of planting structure, so that the rotation area expanded to 1 million mu, middle-yield field for two years for a round, low-yield field
