馬鈴薯高產施肥方法

在種植馬鈴(ling)薯(shu)(shu)(shu)時(shi)，用生物菌(jun)肥(fei)拌種、作基肥(fei)和進行追肥(fei)，能使馬鈴(ling)薯(shu)(shu)(shu)發(fa)芽(ya)快，發(fa)芽(ya)率高，發(fa)芽(ya)整齊，芽(ya)苗健(jian)壯(zhuang)，莖壯(zhuang)葉(xie)綠，不(bu)(bu)受根結線(xian)蟲、疫病(bing)(bing)、軟腐病(bing)(bing)、枯萎病(bing)(bing)為(wei)害，結薯(shu)(shu)(shu)早而多，幼(you)薯(shu)(shu)(shu)發(fa)育好，不(bu)(bu)畸(ji)形，薯(shu)(shu)(shu)型端正，膨(peng)大(da)迅速(su)，淀粉積累多，薯(shu)(shu)(shu)大(da)，植株不(bu)(bu)早衰，產量和品質(zhi)都(dou)明顯提高。具(ju)體施肥(fei)方法(fa)如下：

拌種

將馬(ma)(ma)鈴薯的(de)種(zhong)(zhong)(zhong)(zhong)(zhong)薯縱向切(qie)開后(hou)(hou)，用(yong)馬(ma)(ma)鈴薯種(zhong)(zhong)(zhong)(zhong)(zhong)薯的(de)傷(shang)(shang)口切(qie)面(mian)去蘸生物(wu)菌(jun)肥，使(shi)傷(shang)(shang)口沾(zhan)滿生物(wu)菌(jun)肥后(hou)(hou)再種(zhong)(zhong)(zhong)(zhong)(zhong)植。或將馬(ma)(ma)鈴薯的(de)種(zhong)(zhong)(zhong)(zhong)(zhong)薯放入清(qing)水(shui)中(zhong)浸泡1～2分(fen)鐘，使(shi)馬(ma)(ma)鈴薯種(zhong)(zhong)(zhong)(zhong)(zhong)薯濕潤后(hou)(hou)撈起，再去蘸生物(wu)菌(jun)肥，使(shi)馬(ma)(ma)鈴薯種(zhong)(zhong)(zhong)(zhong)(zhong)薯沾(zhan)滿生物(wu)菌(jun)肥后(hou)(hou)再種(zhong)(zhong)(zhong)(zhong)(zhong)植。也(ye)可(ke)以(yi)在生物(wu)菌(jun)肥中(zhong)加(jia)入少量(liang)的(de)清(qing)水(shui)，充分(fen)攪拌使(shi)其濕潤后(hou)(hou)，再用(yong)馬(ma)(ma)鈴薯種(zhong)(zhong)(zhong)(zhong)(zhong)薯去蘸生物(wu)菌(jun)肥，使(shi)馬(ma)(ma)鈴薯種(zhong)(zhong)(zhong)(zhong)(zhong)薯表面(mian)沾(zhan)滿生物(wu)菌(jun)肥后(hou)(hou)再種(zhong)(zhong)(zhong)(zhong)(zhong)植。

做基肥

在(zai)(zai)種(zhong)(zhong)植(zhi)馬(ma)鈴薯時，每畝用生(sheng)物菌肥(fei)80～100公斤做基(ji)肥(fei)。先挖好種(zhong)(zhong)植(zhi)穴，種(zhong)(zhong)下種(zhong)(zhong)薯，再(zai)在(zai)(zai)種(zhong)(zhong)薯旁邊(bian)均勻(yun)撒施生(sheng)物菌肥(fei)，然后(hou)蓋(gai)(gai)上一層厚8～10厘(li)米(mi)的泥土，將種(zhong)(zhong)薯和生(sheng)物菌肥(fei)全部覆蓋(gai)(gai)住。

追肥

在馬鈴(ling)薯生長發育過程(cheng)中(zhong)，分別(bie)在植株(zhu)高(gao)25～30厘米時(shi)、幼(you)薯開始膨大時(shi)和幼(you)薯迅速膨大時(shi)，各追施一(yi)次生物菌肥(fei)，每次每畝施150～200公斤(jin)。結合(he)培土(tu)，將生物菌肥(fei)均(jun)勻撒施在馬鈴(ling)薯植株(zhu)根部周圍的土(tu)壤中(zhong)后(hou)，培上一(yi)層厚(hou)8～10厘米左右的泥土(tu)即可。
