馬鈴薯高產施肥方法

在種植馬鈴(ling)(ling)薯時，用生物菌(jun)肥(fei)拌種、作基肥(fei)和進(jin)行追肥(fei)，能(neng)使(shi)馬鈴(ling)(ling)薯發(fa)芽(ya)(ya)快，發(fa)芽(ya)(ya)率高，發(fa)芽(ya)(ya)整齊，芽(ya)(ya)苗(miao)健(jian)壯(zhuang)，莖(jing)壯(zhuang)葉綠，不受根結線蟲、疫病(bing)、軟(ruan)腐病(bing)、枯(ku)萎(wei)病(bing)為害(hai)，結薯早(zao)而多，幼薯發(fa)育(yu)好(hao)，不畸(ji)形，薯型端正，膨大迅速，淀粉(fen)積累多，薯大，植株不早(zao)衰，產量和品質都(dou)明顯提高。具(ju)體施肥(fei)方法如下：

拌種

將馬(ma)鈴(ling)(ling)(ling)薯(shu)(shu)的(de)種(zhong)(zhong)薯(shu)(shu)縱向切開后(hou)，用馬(ma)鈴(ling)(ling)(ling)薯(shu)(shu)種(zhong)(zhong)薯(shu)(shu)的(de)傷(shang)口切面去蘸生(sheng)物(wu)(wu)(wu)(wu)(wu)菌(jun)(jun)肥，使(shi)(shi)傷(shang)口沾(zhan)滿(man)生(sheng)物(wu)(wu)(wu)(wu)(wu)菌(jun)(jun)肥后(hou)再(zai)(zai)種(zhong)(zhong)植。或(huo)將馬(ma)鈴(ling)(ling)(ling)薯(shu)(shu)的(de)種(zhong)(zhong)薯(shu)(shu)放入清(qing)水(shui)(shui)中浸泡1～2分(fen)鐘，使(shi)(shi)馬(ma)鈴(ling)(ling)(ling)薯(shu)(shu)種(zhong)(zhong)薯(shu)(shu)濕潤后(hou)撈起，再(zai)(zai)去蘸生(sheng)物(wu)(wu)(wu)(wu)(wu)菌(jun)(jun)肥，使(shi)(shi)馬(ma)鈴(ling)(ling)(ling)薯(shu)(shu)種(zhong)(zhong)薯(shu)(shu)沾(zhan)滿(man)生(sheng)物(wu)(wu)(wu)(wu)(wu)菌(jun)(jun)肥后(hou)再(zai)(zai)種(zhong)(zhong)植。也(ye)可(ke)以在生(sheng)物(wu)(wu)(wu)(wu)(wu)菌(jun)(jun)肥中加入少量的(de)清(qing)水(shui)(shui)，充(chong)分(fen)攪拌使(shi)(shi)其(qi)濕潤后(hou)，再(zai)(zai)用馬(ma)鈴(ling)(ling)(ling)薯(shu)(shu)種(zhong)(zhong)薯(shu)(shu)去蘸生(sheng)物(wu)(wu)(wu)(wu)(wu)菌(jun)(jun)肥，使(shi)(shi)馬(ma)鈴(ling)(ling)(ling)薯(shu)(shu)種(zhong)(zhong)薯(shu)(shu)表面沾(zhan)滿(man)生(sheng)物(wu)(wu)(wu)(wu)(wu)菌(jun)(jun)肥后(hou)再(zai)(zai)種(zhong)(zhong)植。

做基肥

在(zai)種(zhong)(zhong)植馬鈴薯時(shi)，每畝用生(sheng)物(wu)(wu)菌(jun)肥80～100公斤做基肥。先挖好種(zhong)(zhong)植穴，種(zhong)(zhong)下種(zhong)(zhong)薯，再在(zai)種(zhong)(zhong)薯旁邊均勻撒施生(sheng)物(wu)(wu)菌(jun)肥，然后蓋(gai)上(shang)一層厚8～10厘米的(de)泥土(tu)，將種(zhong)(zhong)薯和生(sheng)物(wu)(wu)菌(jun)肥全部覆蓋(gai)住。

追肥

在(zai)(zai)馬鈴薯生長發育(yu)過(guo)程中，分別(bie)在(zai)(zai)植株高25～30厘米時(shi)、幼(you)薯開(kai)始膨大時(shi)和(he)幼(you)薯迅速膨大時(shi)，各追施一(yi)次(ci)生物(wu)菌肥，每次(ci)每畝(mu)施150～200公斤。結(jie)合培土(tu)(tu)，將生物(wu)菌肥均勻撒施在(zai)(zai)馬鈴薯植株根部(bu)周(zhou)圍(wei)的(de)土(tu)(tu)壤中后，培上一(yi)層厚8～10厘米左(zuo)右(you)的(de)泥(ni)土(tu)(tu)即可。
