小麦冬苫是我省关中历史上形成的一种施肥习惯,据说能使小麦“吃”饱“穿”暖、安全越冬。76年我们在长安县纪扬公社调查中发现,事实并非如此。为了验证这一认识,1977—78年我们和郊区水流公社东阳试验站协作,进行了小麦冬苫及其后效试验。现将试验结果分述如下:一、试验方法采用田间小区试验法。试验地设在东阳试验站,土壤系黑垆土,播前土壤养分见表1,前茬玉米,小区面积0.01亩,重复四次,随机排列。指示作物为郑引一号小麦。后效试验指示作物为陕单7号玉米。试验处理见表2。
Winter wheat is a province of Guanzhong in the history of the formation of a fertilization practices, is said to make wheat “eat” full “wear” warm, safe and wintering. In the 76 years we found in Chang’an County Ji Yang Commune Survey, this is not the case. In order to verify this understanding, in 1977-78, we collaborated with Dongyang Experimental Station of Suburban Water Commune to conduct a trial of winter mulberry and its after-effects. Now the test results are as follows: First, the test method field test method. Experimental site located in Dongyang Experimental Station, the soil black loam soil, soil nutrient before sowing in Table 1, before the crop of corn, plot area of 0.01 acres, repeated four times randomly arranged. Indicate the crop as Zheng cited number one wheat. After-effects test indicates that the Shan Shan No. 7 corn. Test treatment in Table 2.
