在现阶段农家肥料缺乏的情况下,如何将已有的农肥对当季作物发挥最大的效果,是一个很有意义的研究课题。为此,须从两方面入手,一方面是研究如何减少农肥的肥分损失,另一方面是研究经济施用方法。本文仅研究农肥经济施用的一种方法——粪耬施肥,现将其调查研究结果简报如下。 一、粪耧施肥的基本情况 粪耧施肥是一种经济有效的集中施肥法,是一种能大面积应用的种子与农肥同时均匀的播入播种沟内的施肥法。豫东于城、夏邑、永城等县青砂土区(轻壤—中壤质浅色草甸土)历史上就有这种施肥习惯。过去
In the current situation of lack of farm manure, it is a very significant research topic how to maximize the effect of existing agricultural fertilizer on the crop. To this end, we must start from two aspects, on the one hand is to study how to reduce the loss of fertilizer fertilizer, on the other hand is to study the economic application method. This paper only studies the economic application of agricultural fertilizer, a method - manure fertilization, now its research findings are summarized below. First, the basic situation of manure fertilization Manure fertilization is a cost-effective method of concentrated fertilization, is a large area can be applied to the seeds and fertilizers evenly sowing ditch within the fertilization method. Yudong in the city, Xiayi, Yongcheng County blue sand area (light soil - medium loamy meadow soil) has this kind of fertilization history. past
