红薯间作玉米(简称薯玉间作)可利用薯、玉株型一高一矮,需光一强一弱,根系一深一浅,生育期一长一短和需肥种类不同等生育特点,而充分利用土地、光能、空间和时间,地上和地下,是一种提高单位面积产量,力争多种、高产、多收的间作方式。 1985年以来,我局分别在襄北岗地区的石桥、黄渠、双沟等乡镇进行了春红薯间作春玉米亩产吨粮高产攻关试验和相应栽培技术的试验、研究,取得了显著成效。三年来试验田平均亩产玉米达到460.05—544.98公斤,红薯干490—583.3公斤,每亩年产粮食达到964.3-1128.28公斤。1987年在黄渠乡二房村科技户彭顺道承包的冷白土低产地上
Sweet potato intercropping corn (hereinafter referred to as intercropping potato) can be used potato, jade plant a tall and a short, a light one strong and one weak, the root of a deep one shallow, one long and one short growth period and fertility needs different types of reproductive characteristics, and full The use of land, light energy, space and time, above and below ground, is an intercropping method to increase yield per unit area and to strive for multiple, high-yield and high yield. Since 1985, our bureau conducted the experiment and research on high-yielding tons of high yield per ton of spring maize and corresponding cultivation techniques of spring sweet potato in Shiqiao, Huangqu and Shuanggou in Xiangbeigang area, respectively, and achieved remarkable results . In the past three years, the average yield per mu of corn reached 460.05-544.98 kg and that of sweet potato was 490-583.3 kg. The annual output of grain per mu reached 964.3-1128.28 kg. In 1987, Huangqu Township, two houses in the village of science and technology Pang Shun Road contracted cold clay low yield land
