我国的红小豆在国际市场上久负盛名,近几年大量出口日本、韩国,货源供不应求。所以,各地种植红小豆的面积逐年增加。为使红小豆种植取得高产、优质、高效,种植中要抓好以下几项措施: 一、选好地红小豆的生长对土壤要求不严格,各类土壤都可种植,尤其在沙壤土地种植红小豆可提早成熟。红小豆不宜重茬,因为重茬可使病虫害加重,杂草丛生,根系发育不良,根瘤减少,降低产量和品质。所以,种红小豆的地块一般需要隔3～4年才能再种。
China’s adzuki beans are prestigious in the international market, in recent years a large number of exports to Japan, South Korea, supply in short supply. Therefore, the area planted with red beans increased year by year. In order to obtain high yield, high quality and high efficiency of red bean cultivation, the following measures should be taken in the cultivation: First, the growth of the selected red bean is not strict with the soil, and all kinds of soil can be planted, especially in sandy soil Adzuki beans can be premature. Red bean is not stubble, because the stubble crop pests and diseases can be increased, overgrown, poor root growth, reduced nodules, reduce yield and quality. Therefore, the kind of red beans generally need to block every 3 to 4 years to re-species.
