采收

      薺(qi)(qi)菜(cai)(cai)是分(fen)次采(cai)(cai)(cai)(cai)收(shou)(shou)，每次采(cai)(cai)(cai)(cai)收(shou)(shou)應采(cai)(cai)(cai)(cai)大留(liu)小，留(liu)植株要均(jun)勻適(shi)當。早秋播(bo)種(zhong)(zhong)薺(qi)(qi)菜(cai)(cai)，真葉10～13片采(cai)(cai)(cai)(cai)收(shou)(shou)，播(bo)種(zhong)(zhong)后(hou)30～35天采(cai)(cai)(cai)(cai)收(shou)(shou)，以(yi)后(hou)分(fen)期收(shou)(shou)獲(huo)4～5次，至翌年3月(yue)下旬結束，畝(mu)總產量(liang)2500～3000公(gong)斤(jin)。10月(yue)上旬播(bo)種(zhong)(zhong)的秋薺(qi)(qi)菜(cai)(cai)，需45～60天，才能(neng)開始(shi)采(cai)(cai)(cai)(cai)收(shou)(shou)。2月(yue)下旬播(bo)種(zhong)(zhong)的薺(qi)(qi)菜(cai)(cai)，4月(yue)上旬采(cai)(cai)(cai)(cai)收(shou)(shou)上市。春播(bo)一(yi)般(ban)采(cai)(cai)(cai)(cai)收(shou)(shou)1～2次，畝(mu)產量(liang)達1000公(gong)斤(jin)左右。

      留種(zhong)

      栽培薺菜需單獨建立留種田，留種田要選擇地勢高燥、排水良好、肥力適中的地塊。留種田一般在9 月下旬～10月初播，用種量1公斤左右，撒播稀勻。2月中旬進行一次株選，拔除細弱、劣株和不符本品種特征的雜株，保持12厘米見方的株行距，并追肥一次。3月下旬抽苔現蕾，4月下旬開花，5月初采收種子。適時(shi)采收是薺(qi)菜留種(zhong)(zhong)的關鍵。當種(zhong)(zhong)莢由青(qing)轉黃七、八成熟時(shi)，為采收適宜時(shi)期，晴(qing)天上午10時(shi)前(qian)收割，就地曬(shai)(shai)1小(xiao)時(shi)，再用薄(bo)膜或被單鋪在田間，搓(cuo)出種(zhong)(zhong)子，揚凈涼干，切忌曝曬(shai)(shai)，每畝收種(zhong)(zhong)子50公斤左右。種(zhong)(zhong)子橘紅色(se)，色(se)澤艷麗，使用年(nian)限2～3年(nian)。
