地处渭河北岸的广大旱塬地区,为我国著名的小麦产区,重要的商品粮基地。但在农业生产上存在两个主要问题,一是干旱缺水,二是土壤瘠薄。本文从旱塬土壤缺水的实际情况出发,研究了有机肥和磷肥对降低小麦生产消耗,提高土壤水分生产效率和抗旱增产等方面的作用。 It is located in the vast dry land of the north bank of the Weihe River and is a well-known wheat producing area in China. It is an important commodity grain base. However, there are two major problems in agricultural production: one is drought and the other is water shortage; the other is soil infertility. Based on the actual situation of soil water shortage in the highland, this paper studied the role of organic and phosphate fertilizers in reducing wheat production and consumption, improving soil water productivity and increasing drought-resistant yield.
