菠菜種子的處(chu)理小技(ji)巧
菠菜種子巧處理,才能高收獲。
1、溶液(ye)(ye)配制:將過(guo)氧化氫(qing)溶液(ye)(ye)按1∶4比例對水(shui),經充分攪拌配制成20%~25%的過(guo)氧化氫(qing)水(shui)溶液(ye)(ye)。
2、浸種(zhong):浸種(zhong)時(shi)間將配制(zhi)好的(de)過氧(yang)化氫(qing)水溶液盛于容器中,倒(dao)入種(zhong)子時(shi)應邊倒(dao)邊用木棒攪拌,使種(zhong)子都能(neng)均勻(yun)吸水。當氣(qi)(qi)溫(wen)(wen)低于20℃時(shi),浸種(zhong)時(shi)間需100~120分鐘;氣(qi)(qi)溫(wen)(wen)高于20℃、低于30℃時(shi),浸種(zhong)時(shi)間60~90分鐘;氣(qi)(qi)溫(wen)(wen)高于30℃以上時(shi),浸種(zhong)時(shi)間30~50分鐘即可。
3、種(zhong)子(zi)催芽(ya):浸種(zhong)后(hou)將種(zhong)子(zi)從過氧化氫水(shui)(shui)溶液中(zhong)撈出,隨即(ji)用清水(shui)(shui)沖(chong)(chong)洗(xi)3~4次(邊沖(chong)(chong)邊濾水(shui)(shui)),濾水(shui)(shui)后(hou)盛于容器(qi)中(zhong)用濕布巾(jin)覆蓋(gai)催芽(ya)。若種(zhong)子(zi)成熟適(shi)度(du)且飽(bao)滿,一般(ban)5~6天就有(you)85%以上的種(zhong)子(zi)發芽(ya),播(bo)種(zhong)后(hou)2~3天即(ji)可齊苗,比常規播(bo)種(zhong)提(ti)前6~8天出苗。
4、注意事項:
(1)用過氧化氫水溶(rong)液浸種(zhong)(zhong)處(chu)理前,應把自留的或購(gou)買(mai)的菠菜(cai)種(zhong)(zhong)子選擇晴(qing)天(tian)太陽下曬4~6小時,并(bing)剔除雜物和不(bu)飽滿的種(zhong)(zhong)子;
(2)要用百菌清水溶液對(dui)已(yi)經浸種(zhong)催芽處理(li)的種(zhong)子進行滅菌處理(li);
(3)浸種(zhong)催芽滅菌處理后的種(zhong)子(zi)應及時(shi)播種(zhong),大(da)田(tian)(大(da)棚)土壤要求濕潤;
(4)播種后覆(fu)土1~1.5厘米并加(jia)壓,使土壤(rang)與種子吻合,再(zai)用稻草簾覆(fu)蓋,待有10%~15%的幼苗(miao)出(chu)土時(shi)將草簾掀(xian)開。
