川南浅丘双季稻定位试验是“川南浅丘稻田基本耕作制度定位评价研究”的部分内容,为研究双季稻在川东南浅丘区恢复和发展,现结合试验取得的结果谈谈以下看法。一、九年定位试验较为真实客观地反映了川南浅丘稻田各主要种植方式的产量潜力及生态稳定性,为回答生产提出的问题提供了较为可靠的试验依据。试验从1980—1988年经历了不同气侯生态年;小区面积0.125亩,重复二次,试验以三年为一周期,各季作物供试品种均为当时生产上的主栽品种:各季作物播期、栽期、育秧方法年度是均大体一致;每年各季水稻的施肥量相等;均去除边三行收
The study on the location of double cropping rice in shallow hill mound in southern Sichuan is part of “the research on the orientation evaluation of basic farming system in shallow hill milled rice in southern Sichuan”. In order to study the recovery and development of double cropping rice in the shallow hill area of southeast Sichuan, the following observations are given. The first and the nine-year experiments have more objectively and objectively reflected the yield potential and ecological stability of the main planting methods in shallow hillside rice fields in southern Sichuan Province, and provided a reliable experimental basis for answering the questions raised in the production. The experiment experienced different climatic ecological years from 1980 to 1988. The plot area was 0.125 mu and was repeated twice. The experiment was conducted in three years as one cycle. The cultivars tested in each season were the main cultivars at that time: the crops of all seasons Sowing date, planted, seedling methods are generally the same year; the amount of rice in each quarter of the same amount of fertilizer;
