高产麦田在耧播和群体较少,即每亩基本苗3—6万,成穗30—40万的条件下,要求亩产1200斤,究竟应该怎样经济合理施肥呢?目前有不少争论,有的认为高产麦田地力肥,只要基肥多施农家肥作基肥,还应多施氮素化肥才能创高产;也有的主张既要施用氮素化肥,又要重施磷肥。为了明确这些问题,我们在黄庄大队和冯西大队的科技队进行了试验和调查,结果简报如下:
High-yielding wheat fields in the broadcast and less groups, that is, basic seedlings per acre 3-6 million, into the conditions of 30-40 million, requiring 1200 kg per mu, what should be economical and rational fertilization? There are many controversies, Some think high-yield wheatfield fertility, as long as the base fertilizer more man-made fertilizer for basal fertilizer, nitrogen fertilizer should be more in order to create high yield; Some advocates both the application of nitrogen fertilizer, but also re-phosphate. In order to clarify these problems, we carried out experiments and investigations in the scientific and technological team of Huangzhuang Brigade and Fengxi Brigade. The result briefing is as follows:
