菠菜種(zhong)子的處理小技巧
菠菜種子巧處理,才能高收獲。
1、溶(rong)液(ye)配制:將過(guo)(guo)氧化氫溶(rong)液(ye)按(an)1∶4比例對水,經充(chong)分攪拌配制成20%~25%的過(guo)(guo)氧化氫水溶(rong)液(ye)。
2、浸(jin)(jin)種(zhong):浸(jin)(jin)種(zhong)時(shi)(shi)間(jian)將配(pei)制好的過氧化氫水溶液盛于容(rong)器中,倒(dao)入(ru)種(zhong)子時(shi)(shi)應邊(bian)(bian)倒(dao)邊(bian)(bian)用木棒攪(jiao)拌,使種(zhong)子都能均(jun)勻吸水。當氣(qi)(qi)溫低于20℃時(shi)(shi),浸(jin)(jin)種(zhong)時(shi)(shi)間(jian)需100~120分(fen)鐘(zhong);氣(qi)(qi)溫高于20℃、低于30℃時(shi)(shi),浸(jin)(jin)種(zhong)時(shi)(shi)間(jian)60~90分(fen)鐘(zhong);氣(qi)(qi)溫高于30℃以上時(shi)(shi),浸(jin)(jin)種(zhong)時(shi)(shi)間(jian)30~50分(fen)鐘(zhong)即可(ke)。
3、種子(zi)催芽:浸種后(hou)將種子(zi)從過氧化氫水(shui)溶液中撈出,隨即用(yong)清水(shui)沖(chong)洗3~4次(邊沖(chong)邊濾(lv)水(shui)),濾(lv)水(shui)后(hou)盛于容器中用(yong)濕布巾覆蓋催芽。若種子(zi)成熟適度且飽滿,一般5~6天就有85%以上的(de)種子(zi)發芽,播種后(hou)2~3天即可齊(qi)苗(miao),比常規播種提前6~8天出苗(miao)。
4、注意事項:
(1)用過氧化氫水溶液浸(jin)種(zhong)(zhong)處理前,應把自留的或購(gou)買的菠菜種(zhong)(zhong)子選擇晴天太(tai)陽(yang)下(xia)曬4~6小時,并剔除雜(za)物和不飽(bao)滿的種(zhong)(zhong)子;
(2)要(yao)用(yong)百菌清(qing)水溶液對已經浸種(zhong)催芽處理(li)(li)的種(zhong)子進(jin)行(xing)滅菌處理(li)(li);
(3)浸種(zhong)催芽滅菌處理后的種(zhong)子應及時(shi)播種(zhong),大(da)田(tian)(大(da)棚(peng))土壤要求濕潤(run);
(4)播種后(hou)覆(fu)土(tu)1~1.5厘米(mi)并加壓,使(shi)土(tu)壤與種子吻(wen)合(he),再用稻草簾覆(fu)蓋,待(dai)有10%~15%的(de)幼苗出土(tu)時將(jiang)草簾掀開。
