馬(ma)鈴(ling)薯(shu)高產施肥方法

在種(zhong)植馬鈴(ling)薯(shu)(shu)時(shi)，用生物(wu)菌肥(fei)拌種(zhong)、作基(ji)肥(fei)和進(jin)行追肥(fei)，能使馬鈴(ling)薯(shu)(shu)發(fa)芽(ya)快，發(fa)芽(ya)率(lv)高，發(fa)芽(ya)整齊，芽(ya)苗健壯，莖壯葉綠(lv)，不受根結線蟲(chong)、疫病(bing)、軟(ruan)腐病(bing)、枯萎病(bing)為害(hai)，結薯(shu)(shu)早而(er)多，幼(you)薯(shu)(shu)發(fa)育好，不畸形，薯(shu)(shu)型端正，膨大迅速，淀(dian)粉(fen)積累(lei)多，薯(shu)(shu)大，植株(zhu)不早衰，產量和品質都(dou)明顯提高。具體施(shi)肥(fei)方法如下(xia)：

拌種

將馬(ma)(ma)(ma)鈴薯(shu)(shu)(shu)(shu)的種(zhong)薯(shu)(shu)(shu)(shu)縱向切開后(hou)，用(yong)馬(ma)(ma)(ma)鈴薯(shu)(shu)(shu)(shu)種(zhong)薯(shu)(shu)(shu)(shu)的傷口(kou)切面去(qu)蘸(zhan)(zhan)生(sheng)(sheng)(sheng)物(wu)菌(jun)(jun)肥(fei)(fei)，使(shi)傷口(kou)沾滿(man)生(sheng)(sheng)(sheng)物(wu)菌(jun)(jun)肥(fei)(fei)后(hou)再(zai)種(zhong)植。或將馬(ma)(ma)(ma)鈴薯(shu)(shu)(shu)(shu)的種(zhong)薯(shu)(shu)(shu)(shu)放入(ru)清(qing)水中浸泡1～2分鐘，使(shi)馬(ma)(ma)(ma)鈴薯(shu)(shu)(shu)(shu)種(zhong)薯(shu)(shu)(shu)(shu)濕(shi)潤后(hou)撈起，再(zai)去(qu)蘸(zhan)(zhan)生(sheng)(sheng)(sheng)物(wu)菌(jun)(jun)肥(fei)(fei)，使(shi)馬(ma)(ma)(ma)鈴薯(shu)(shu)(shu)(shu)種(zhong)薯(shu)(shu)(shu)(shu)沾滿(man)生(sheng)(sheng)(sheng)物(wu)菌(jun)(jun)肥(fei)(fei)后(hou)再(zai)種(zhong)植。也可以(yi)在生(sheng)(sheng)(sheng)物(wu)菌(jun)(jun)肥(fei)(fei)中加入(ru)少(shao)量的清(qing)水，充(chong)分攪拌使(shi)其濕(shi)潤后(hou)，再(zai)用(yong)馬(ma)(ma)(ma)鈴薯(shu)(shu)(shu)(shu)種(zhong)薯(shu)(shu)(shu)(shu)去(qu)蘸(zhan)(zhan)生(sheng)(sheng)(sheng)物(wu)菌(jun)(jun)肥(fei)(fei)，使(shi)馬(ma)(ma)(ma)鈴薯(shu)(shu)(shu)(shu)種(zhong)薯(shu)(shu)(shu)(shu)表面沾滿(man)生(sheng)(sheng)(sheng)物(wu)菌(jun)(jun)肥(fei)(fei)后(hou)再(zai)種(zhong)植。

做基肥

在(zai)種(zhong)(zhong)(zhong)植馬(ma)鈴薯時，每畝用生物(wu)菌肥80～100公斤做(zuo)基肥。先挖好種(zhong)(zhong)(zhong)植穴，種(zhong)(zhong)(zhong)下(xia)種(zhong)(zhong)(zhong)薯，再在(zai)種(zhong)(zhong)(zhong)薯旁邊(bian)均勻撒施(shi)生物(wu)菌肥，然后蓋(gai)上一(yi)層厚8～10厘米(mi)的泥土(tu)，將種(zhong)(zhong)(zhong)薯和生物(wu)菌肥全部覆(fu)蓋(gai)住。

追肥

在馬鈴薯生(sheng)長發(fa)育過程(cheng)中，分別在植株(zhu)(zhu)高(gao)25～30厘米時(shi)、幼薯開始(shi)膨大(da)時(shi)和(he)幼薯迅(xun)速膨大(da)時(shi)，各追施一次生(sheng)物菌肥(fei)，每(mei)次每(mei)畝(mu)施150～200公斤。結合(he)培土，將(jiang)生(sheng)物菌肥(fei)均勻(yun)撒施在馬鈴薯植株(zhu)(zhu)根部周(zhou)圍的(de)土壤中后，培上(shang)一層厚8～10厘米左右(you)的(de)泥土即可。
