馬鈴薯高產施肥方法

在(zai)種(zhong)植馬鈴薯時(shi)，用生物(wu)菌肥(fei)拌種(zhong)、作基肥(fei)和(he)進行追肥(fei)，能使馬鈴薯發(fa)芽(ya)(ya)快，發(fa)芽(ya)(ya)率(lv)高(gao)，發(fa)芽(ya)(ya)整(zheng)齊，芽(ya)(ya)苗健(jian)壯，莖壯葉綠，不(bu)受根(gen)結線蟲(chong)、疫病、軟腐(fu)病、枯萎病為害(hai)，結薯早(zao)而多(duo)，幼薯發(fa)育好，不(bu)畸(ji)形，薯型端正，膨(peng)大迅速，淀粉積累(lei)多(duo)，薯大，植株不(bu)早(zao)衰，產量和(he)品質都明顯(xian)提高(gao)。具體(ti)施肥(fei)方法(fa)如下：

拌種

將馬(ma)(ma)(ma)(ma)鈴薯(shu)(shu)(shu)(shu)的(de)(de)(de)種(zhong)(zhong)(zhong)(zhong)(zhong)薯(shu)(shu)(shu)(shu)縱向切開(kai)后，用(yong)馬(ma)(ma)(ma)(ma)鈴薯(shu)(shu)(shu)(shu)種(zhong)(zhong)(zhong)(zhong)(zhong)薯(shu)(shu)(shu)(shu)的(de)(de)(de)傷口切面(mian)去(qu)(qu)蘸(zhan)生(sheng)物菌肥(fei)，使(shi)(shi)傷口沾(zhan)滿生(sheng)物菌肥(fei)后再(zai)種(zhong)(zhong)(zhong)(zhong)(zhong)植。或將馬(ma)(ma)(ma)(ma)鈴薯(shu)(shu)(shu)(shu)的(de)(de)(de)種(zhong)(zhong)(zhong)(zhong)(zhong)薯(shu)(shu)(shu)(shu)放入清(qing)水(shui)中浸泡(pao)1～2分(fen)鐘，使(shi)(shi)馬(ma)(ma)(ma)(ma)鈴薯(shu)(shu)(shu)(shu)種(zhong)(zhong)(zhong)(zhong)(zhong)薯(shu)(shu)(shu)(shu)濕潤(run)后撈起，再(zai)去(qu)(qu)蘸(zhan)生(sheng)物菌肥(fei)，使(shi)(shi)馬(ma)(ma)(ma)(ma)鈴薯(shu)(shu)(shu)(shu)種(zhong)(zhong)(zhong)(zhong)(zhong)薯(shu)(shu)(shu)(shu)沾(zhan)滿生(sheng)物菌肥(fei)后再(zai)種(zhong)(zhong)(zhong)(zhong)(zhong)植。也可以在生(sheng)物菌肥(fei)中加入少量的(de)(de)(de)清(qing)水(shui)，充分(fen)攪拌使(shi)(shi)其濕潤(run)后，再(zai)用(yong)馬(ma)(ma)(ma)(ma)鈴薯(shu)(shu)(shu)(shu)種(zhong)(zhong)(zhong)(zhong)(zhong)薯(shu)(shu)(shu)(shu)去(qu)(qu)蘸(zhan)生(sheng)物菌肥(fei)，使(shi)(shi)馬(ma)(ma)(ma)(ma)鈴薯(shu)(shu)(shu)(shu)種(zhong)(zhong)(zhong)(zhong)(zhong)薯(shu)(shu)(shu)(shu)表面(mian)沾(zhan)滿生(sheng)物菌肥(fei)后再(zai)種(zhong)(zhong)(zhong)(zhong)(zhong)植。

做基肥

在(zai)(zai)種植馬(ma)鈴薯(shu)(shu)(shu)時，每畝用生物菌肥80～100公斤做基肥。先挖(wa)好(hao)種植穴，種下種薯(shu)(shu)(shu)，再在(zai)(zai)種薯(shu)(shu)(shu)旁邊均(jun)勻撒施生物菌肥，然后蓋(gai)(gai)上(shang)一層厚8～10厘(li)米的泥土(tu)，將(jiang)種薯(shu)(shu)(shu)和生物菌肥全(quan)部覆蓋(gai)(gai)住。

追肥

在(zai)馬鈴(ling)薯生(sheng)長發育過(guo)程(cheng)中，分別在(zai)植株高25～30厘(li)(li)米時、幼薯開始膨(peng)大時和幼薯迅速(su)膨(peng)大時，各追施一次生(sheng)物菌(jun)肥，每(mei)次每(mei)畝施150～200公(gong)斤。結合培土(tu)，將生(sheng)物菌(jun)肥均勻撒施在(zai)馬鈴(ling)薯植株根部周圍的(de)土(tu)壤中后(hou)，培上(shang)一層厚(hou)8～10厘(li)(li)米左右的(de)泥土(tu)即可。
