湖南湘潭县射埠区农民在晚稻专用秧田里,春季种植早熟黄瓜,黄瓜收获后水播晚稻秧,拔完秧苗插晚稻,群众称为瓜—秧—稻耕作制。1986年全区示范面积158.3亩,平均亩产黄瓜1560公斤,亩收入为300—400元。农民彭德平利用三分五厘晚稻专用秧田栽“早丰一号”良种黄瓜387蔸,收入144.5元。通过两年来的实践,总结这种轮作制有如下好处:一是改良土壤结构。通过冬春二季干田早作,有利于土壤通透性增加,有毒物质减少,改善了土壤理化性状,改变了稻田的生态环境,是挖潜治本的有效措施。二是能促进微生物的活动,提高地力,增加肥效,有利培育壮秧,提高晚稻产量。三是提高复种指数,增加农民收入。
Xiangtan County, Hunan farmers in late rice paddies dedicated seedling field, early spring cucumber cucumber planting, cucumber harvest late rice seedlings planted water, pull out the late rice paddy seedlings, the masses known as the melon - seedlings - rice farming system. In 1986 the demonstration area of 158.3 acres of the region, the average mu produce 1560 kilograms of cucumber, mu income 300-400 yuan. Pei-ping Pei farmers use three minutes and five nights late special rice planted “ZF No. 1” cucumber 387 良, income 144.5 yuan. After two years of practice, this round of crop production has the following advantages: First, improve the soil structure. Through the early winter and spring dry season as early as Gan Tian, is conducive to increased permeability of the soil, reduce toxic substances, improve the physical and chemical properties of the soil, changing the ecological environment in paddy fields, is an effective measure to tap the potential. Second, it can promote the activities of microorganisms, improve soil fertility, increase fertilizer efficiency, favorable nurturing strong seedling, improve late rice yield. Third, raise the multiple cropping index and increase the peasants’ income.
