馬(ma)鈴(ling)薯高產施(shi)肥方法

在種(zhong)植馬鈴(ling)薯(shu)時，用生(sheng)物菌肥拌種(zhong)、作基肥和進行追肥，能(neng)使馬鈴(ling)薯(shu)發芽(ya)快，發芽(ya)率(lv)高(gao)，發芽(ya)整齊，芽(ya)苗健壯，莖壯葉綠，不受根結線蟲、疫病(bing)、軟腐病(bing)、枯(ku)萎病(bing)為害(hai)，結薯(shu)早而多(duo)，幼薯(shu)發育好，不畸(ji)形，薯(shu)型(xing)端正，膨大迅速，淀粉積累多(duo)，薯(shu)大，植株不早衰(shuai)，產量和品(pin)質都明顯提高(gao)。具體(ti)施肥方法如(ru)下：

拌種

將(jiang)馬(ma)(ma)鈴(ling)(ling)(ling)薯(shu)(shu)(shu)(shu)的種(zhong)(zhong)薯(shu)(shu)(shu)(shu)縱向切開(kai)后(hou)，用(yong)馬(ma)(ma)鈴(ling)(ling)(ling)薯(shu)(shu)(shu)(shu)種(zhong)(zhong)薯(shu)(shu)(shu)(shu)的傷口(kou)(kou)切面去蘸(zhan)生(sheng)物(wu)菌(jun)(jun)肥(fei)(fei)(fei)，使(shi)傷口(kou)(kou)沾(zhan)滿生(sheng)物(wu)菌(jun)(jun)肥(fei)(fei)(fei)后(hou)再(zai)種(zhong)(zhong)植。或(huo)將(jiang)馬(ma)(ma)鈴(ling)(ling)(ling)薯(shu)(shu)(shu)(shu)的種(zhong)(zhong)薯(shu)(shu)(shu)(shu)放入清水中浸泡1～2分鐘，使(shi)馬(ma)(ma)鈴(ling)(ling)(ling)薯(shu)(shu)(shu)(shu)種(zhong)(zhong)薯(shu)(shu)(shu)(shu)濕(shi)潤后(hou)撈起，再(zai)去蘸(zhan)生(sheng)物(wu)菌(jun)(jun)肥(fei)(fei)(fei)，使(shi)馬(ma)(ma)鈴(ling)(ling)(ling)薯(shu)(shu)(shu)(shu)種(zhong)(zhong)薯(shu)(shu)(shu)(shu)沾(zhan)滿生(sheng)物(wu)菌(jun)(jun)肥(fei)(fei)(fei)后(hou)再(zai)種(zhong)(zhong)植。也可以(yi)在生(sheng)物(wu)菌(jun)(jun)肥(fei)(fei)(fei)中加入少(shao)量的清水，充分攪(jiao)拌(ban)使(shi)其(qi)濕(shi)潤后(hou)，再(zai)用(yong)馬(ma)(ma)鈴(ling)(ling)(ling)薯(shu)(shu)(shu)(shu)種(zhong)(zhong)薯(shu)(shu)(shu)(shu)去蘸(zhan)生(sheng)物(wu)菌(jun)(jun)肥(fei)(fei)(fei)，使(shi)馬(ma)(ma)鈴(ling)(ling)(ling)薯(shu)(shu)(shu)(shu)種(zhong)(zhong)薯(shu)(shu)(shu)(shu)表面沾(zhan)滿生(sheng)物(wu)菌(jun)(jun)肥(fei)(fei)(fei)后(hou)再(zai)種(zhong)(zhong)植。

做基肥

在種(zhong)(zhong)植馬鈴薯(shu)(shu)時，每畝(mu)用生(sheng)(sheng)物菌肥80～100公斤做基(ji)肥。先挖(wa)好種(zhong)(zhong)植穴，種(zhong)(zhong)下種(zhong)(zhong)薯(shu)(shu)，再(zai)在種(zhong)(zhong)薯(shu)(shu)旁邊均(jun)勻撒施生(sheng)(sheng)物菌肥，然后蓋上一層(ceng)厚8～10厘米的泥(ni)土，將種(zhong)(zhong)薯(shu)(shu)和生(sheng)(sheng)物菌肥全(quan)部覆蓋住(zhu)。

追肥

在(zai)馬鈴(ling)薯(shu)生長發(fa)育過程中，分(fen)別(bie)在(zai)植(zhi)株高25～30厘米時、幼薯(shu)開始膨(peng)大(da)時和幼薯(shu)迅速膨(peng)大(da)時，各追施(shi)(shi)一(yi)次(ci)生物(wu)菌(jun)肥，每次(ci)每畝施(shi)(shi)150～200公斤。結合(he)培土，將生物(wu)菌(jun)肥均勻撒施(shi)(shi)在(zai)馬鈴(ling)薯(shu)植(zhi)株根部周圍的土壤中后，培上一(yi)層厚8～10厘米左右(you)的泥土即可(ke)。
