1995～1998年,结合“双千五田”立体栽培理论体系研究,概括了2种基本类型,实施了“8法”技术体系,取得了极显著的经济效益。4年来,累计试验、示范、推广“双千五田”立体栽培面积269.21hm~2。据在基点村的测产和分析,比对照田(等行距单作玉米)增粮38.5%,增值100.4%,增效117.1%,增加投入产出比25.4%。
From 1995 to 1998, combined with the study of “Shuangqianwu” three-dimensional cultivation theory system, two basic types were summarized, and the “Eight Method” technical system was implemented, and remarkable economic benefits were obtained. Over the past 4 years, a total of 269.21hm ~ 2 of cultivated area has been tested, demonstrated and popularized. According to the survey and production in Jiading Village, 38.5% of the grain is increased compared with that of the control field (single crop of corn from one row to another) with a gain of 100.4%, a gain of 117.1% and an increase of the input-output ratio of 25.4%.
