Abstract
臺灣近年稻田紅米混雜情形日漸普遍，已知紅米混雜率上升會造成產量下降及降低商品價值，又期作間農民多數採取翻耕促進田間雜草分解，但一、二期作間隔時間短，翻耕易使土表紅米落粒稻種翻入深層土壤，危害後續期作。為提高農民防除積性並建立有效防除法，本研究於2018年起至2020年為止收集美濃契作、慣行區與杉林慣行區分層取樣共4,031個種子批。 In Taiwan, the prevalence of weedy rice (WR) contamination in Taiwan paddy field has experienced a significant increase. This weed contamination leads to a reduction in the yield and commodity value of cultivated rice. To combat this, many farmers use tillage to promote weed decomposition in gap between seasons. However, this practice can increase the density of soil seedbank, leading to harm in subsequent crops. To address this issue and establish effective weed control methods, we conducted a study the collected 4,031 seed lots through stratified sampling from the Meinong contract farming area.
