为了探讨花生不同叶龄施氮肥对花生的增产效应,摸索氮肥的施用适期和施用量,我们于1983年秋——1984年秋进行了本试验,现将试验结果总结如下。 一、材料与方法 试验在本校教学农场进行,试验地土质为壤土。肥力状况:碱解氮120PP_m、速效钾75PP_m、有效磷7PP_m、有机质含量2.2％,前作玉米,供试品种为粤油551—116。
In order to explore the peanut different leaf age of peanut on the peanut yield-increasing effect, to explore the application of nitrogen fertilizer and the application rate, we conducted in the autumn of 1983 - the fall of 1984 this test, the test results are summarized below. First, the material and method test in our school teaching farm, soil test for the loam. Fertility status: 120PP_set nitrogen, available potassium 75PP_m, available phosphorus 7PP_m, organic matter content of 2.2%, before the corn, the test varieties Yueyou 551-116.
