在種(zhong)植馬鈴(ling)薯(shu)時(shi)，用(yong)生物菌肥(fei)拌種(zhong)、作基肥(fei)和進行追(zhui)肥(fei)，能使馬鈴(ling)薯(shu)發(fa)芽(ya)快(kuai)，發(fa)芽(ya)率高，發(fa)芽(ya)整齊，芽(ya)苗健壯，莖壯葉綠，不(bu)受根結(jie)線蟲、疫病(bing)、軟腐(fu)病(bing)、枯(ku)萎病(bing)為害，結(jie)薯(shu)早而多，幼薯(shu)發(fa)育(yu)好，不(bu)畸形(xing)，薯(shu)型(xing)端(duan)正，膨(peng)大迅(xun)速，淀粉積累多，薯(shu)大，植株(zhu)不(bu)早衰，產(chan)量和品質都明顯提高。具(ju)體施肥(fei)方法如下：

　　拌(ban)種(zhong)(zhong)。將(jiang)馬(ma)(ma)鈴薯(shu)(shu)(shu)(shu)的(de)種(zhong)(zhong)薯(shu)(shu)(shu)(shu)縱(zong)向切(qie)開后(hou)(hou)(hou)，用(yong)馬(ma)(ma)鈴薯(shu)(shu)(shu)(shu)種(zhong)(zhong)薯(shu)(shu)(shu)(shu)的(de)傷口(kou)(kou)切(qie)面去(qu)蘸(zhan)(zhan)生(sheng)物(wu)(wu)菌(jun)肥(fei)，使(shi)傷口(kou)(kou)沾滿(man)生(sheng)物(wu)(wu)菌(jun)肥(fei)后(hou)(hou)(hou)再(zai)(zai)(zai)種(zhong)(zhong)植(zhi)。或(huo)將(jiang)馬(ma)(ma)鈴薯(shu)(shu)(shu)(shu)的(de)種(zhong)(zhong)薯(shu)(shu)(shu)(shu)放入(ru)清(qing)水(shui)(shui)中浸(jin)泡1～2分(fen)鐘，使(shi)馬(ma)(ma)鈴薯(shu)(shu)(shu)(shu)種(zhong)(zhong)薯(shu)(shu)(shu)(shu)濕潤后(hou)(hou)(hou)撈起，再(zai)(zai)(zai)去(qu)蘸(zhan)(zhan)生(sheng)物(wu)(wu)菌(jun)肥(fei)，使(shi)馬(ma)(ma)鈴薯(shu)(shu)(shu)(shu)種(zhong)(zhong)薯(shu)(shu)(shu)(shu)沾滿(man)生(sheng)物(wu)(wu)菌(jun)肥(fei)后(hou)(hou)(hou)再(zai)(zai)(zai)種(zhong)(zhong)植(zhi)。也可以在生(sheng)物(wu)(wu)菌(jun)肥(fei)中加入(ru)少量的(de)清(qing)水(shui)(shui)，充分(fen)攪拌(ban)使(shi)其濕潤后(hou)(hou)(hou)，再(zai)(zai)(zai)用(yong)馬(ma)(ma)鈴薯(shu)(shu)(shu)(shu)種(zhong)(zhong)薯(shu)(shu)(shu)(shu)去(qu)蘸(zhan)(zhan)生(sheng)物(wu)(wu)菌(jun)肥(fei)，使(shi)馬(ma)(ma)鈴薯(shu)(shu)(shu)(shu)種(zhong)(zhong)薯(shu)(shu)(shu)(shu)表面沾滿(man)生(sheng)物(wu)(wu)菌(jun)肥(fei)后(hou)(hou)(hou)再(zai)(zai)(zai)種(zhong)(zhong)植(zhi)。

　　做基肥。在種(zhong)(zhong)(zhong)植(zhi)馬(ma)鈴薯(shu)時，每畝用生(sheng)物(wu)(wu)(wu)菌(jun)肥80～100公斤做基肥。先挖好(hao)種(zhong)(zhong)(zhong)植(zhi)穴，種(zhong)(zhong)(zhong)下種(zhong)(zhong)(zhong)薯(shu)，再在種(zhong)(zhong)(zhong)薯(shu)旁(pang)邊均(jun)勻撒施生(sheng)物(wu)(wu)(wu)菌(jun)肥，然后蓋(gai)上一層厚8～10厘米的泥土，將種(zhong)(zhong)(zhong)薯(shu)和生(sheng)物(wu)(wu)(wu)菌(jun)肥全部覆蓋(gai)住。

　　追肥。在(zai)(zai)馬(ma)鈴薯生長(chang)發育過程中，分(fen)別在(zai)(zai)植(zhi)株高25～30厘(li)米時(shi)(shi)、幼薯開(kai)始(shi)膨大時(shi)(shi)和(he)幼薯迅速膨大時(shi)(shi)，各追施一次生物菌(jun)肥，每(mei)次每(mei)畝施150～200公斤。結合培土，將(jiang)生物菌(jun)肥均勻撒施在(zai)(zai)馬(ma)鈴薯植(zhi)株根部周圍(wei)的(de)土壤中后，培上一層厚8～10厘(li)米左右的(de)泥土即(ji)可。
