我国许多省市区大面积推广运用叶面施肥,将肥料溶解于水,喷洒在作物叶片上,通过叶片气孔吸收养分。其优点是肥料用量小、成本低、效益高。随着我县农业生产不断发展,如何经济、合理施用肥料,使肥料发挥更大增产作用,已成为我县农业生产中急待解决的问题。为了寻找一条施肥新途径,去年我们对叶面施肥进行初步探讨,现将试验结果简结如下。
Many provinces and cities in China popularize the use of large areas of foliar fertilization, the fertilizer dissolved in water, sprayed on crop leaves, leaf stomatal absorption of nutrients. The advantage is a small amount of fertilizer, low cost, high efficiency. With the continuous development of agricultural production in our county, how to use fertilizers economically and rationally to make fertilizers play a greater role in increasing yield has become an urgent problem in agricultural production in our county. In order to find a new way to fertilize, last year we conducted a preliminary study of foliar fertilization, the test results are summarized as follows.
