１９８６—１９９１年，经过调查、试验、示范，筛选出对主作红麻生长影响小，经济、生态效益明显提高的麻田种植新组合：“麦／矮杆四季豆／红麻──秋菜”、“麦／红麻──晚稻”等。１９９０—１９９１年，“麦／矮杆四季豆／红麻──秋菜”组合省内多点示范１２０亩，亩产原麻４８０．７４公斤，全年合计亩产值１２１６元，比对照“麦／红麻──秋菜”组合增产值４０．４％。“麦／红麻──晚稻”组合示范４１．４３亩，亩产原麻３８４．４２公斤，全年亩产值合计８７５．０２元。获得了较好的经济效益，并且增产淡季蔬菜、优质粮食，提高了土壤肥力，生态效益明显提高。同时，研究了配套栽培技术。
From 1986 to 1991, after the investigation, experiment and demonstration, we screened the new combination of planting field of maize which has little influence on the main growth of kenaf and major economic and ecological benefits: “wheat / dwarf green beans / kenaf - autumn vegetables” “Wheat / kenaf - late rice” and so on. 1990-1991, “wheat / diced green beans / kenaf - autumn vegetables” combination of multi-point demonstration province of 120 acres, 480.74 kilograms per mu of raw linen, the annual total output value of 1216 yuan per mu, compared with the control “wheat / Kenaf ─ ─ autumn vegetables ”portfolio output value of 40.4%. The combination of “wheat / kenaf - late rice” demonstrated 41.43 mu, 384.42 kg of mu per mu, and the annual output value of mu totaled 875.02 yuan. Obtained a better economic efficiency, and increased production of off-season vegetables, high-quality food, improve soil fertility, significantly improved ecological benefits. At the same time, the study of supporting cultivation techniques.
