菠菜栽培“三部曲”

發(fā)布時(shí)間：2014-08-06 08:31:58 來(lái)源：農(nóng)民日?qǐng)?bào) 作者：佚名責(zé)任編輯：羅伯特

　　播種菠菜以撒播為主，也可條播。在高溫條件下因發(fā)芽緩慢，故早秋播種的宜浸種催芽，即將種子浸12小時(shí)后，放在4℃低溫的冰箱中處理24小時(shí)，然后在15℃～25℃條件下催芽數(shù)日，待大部分發(fā)芽后即可撒播。每畝播種量10公斤左右，播后蓋淺土或澆糞水及覆蓋稻草、瓜藤等，以降低地溫和保持土壤濕潤(rùn)。9月上旬以后播種不必催芽，播種量可減少到每畝5～7.5公斤。

　　田間管理以肥水為主。播種前應(yīng)施基肥，一般澆施人糞尿，追肥可結(jié)合灌溉進(jìn)行，幼苗小時(shí)宜施稀薄的人糞尿。植株較大及氣溫下降后，濃度可適當(dāng)提高。通常菠菜是分次間拔收獲，每次收獲后都要追肥。早期要注意及時(shí)拔草，并注意防治蚜蟲(chóng)為害。

　　收獲秋播菠菜葉長(zhǎng)15厘米以上，植株間較擁擠時(shí)開(kāi)始間拔收獲，每隔20天左右收一次。周榮忠
