小麦是需要氮、磷、钾较多的作物,其吸收三要素量可作为确定施肥量的重要依据;为了摸索其规律性,我们观察了几个小麦品种对氮、磷、钾三要素吸收和土壤供应情况。本文是不同小麦品种对三要素吸收特点部分的初报。一、试验地土壤基础和试验方法试验于1982—1983年在县试验场和城关乡的原庄、东仲许、西仲许村进行。土壤为褐土化两合土,耕层有机质含量1.08—1.18%;全N0.063—0.079%;速效N20.1—22.8ppm;碱解N56
Wheat is a crop that needs more nitrogen, phosphorus and potassium, and the three elements of its absorption can be used as an important basis to determine the amount of fertilizer. In order to explore its regularity, we observed the absorption and accumulation of nitrogen, phosphorus and potassium in several wheat cultivars Soil supply. This article is the first report on the absorption characteristics of the three elements of different wheat varieties. First, the experimental soil foundation and test methods Test in 1982-1983 in the county test site and Chengguan Township, the original village, East Zhong Xu, Xixian Xu village. The soil is composed of two parts of cinnamon soil, tillage organic matter content of 1.08-1.18%; all N0.063-0.079%; available N20.1-22.8ppm; alkali hydrolysis N56
