近年来,随着化肥品种的增多,施用量不断增加,但农民因施用不当而造成缺苗和毁种减产的现象在生产上屡有发生,在我省干旱缺水的中部地区尤其常见。本研究从生产实践出发对当前生产上常用的化肥品种对旱地春小麦出苗成穗及产量的影响进行了田间试验,通过试验,基本上明确了不同化肥品种在当地条件下的合理用量及施肥方式,现简报如下: 一、试验方法: 试验设在定西唐家堡试验区进行。试验地土壤为川地麻土。供试化肥品种有硝铵、尿素、
In recent years, with the increase of fertilizer varieties and the increasing application rates, the phenomenon of lack of seedlings and the loss of seed production due to improper application of peasants has frequently occurred in production, especially in the drought-stricken central region of our province. In this study, field experiments were carried out on the effects of fertilizer varieties commonly used in production on sprouting and yield of spring wheat in dryland. Experiments were conducted to basically confirm the reasonable dosage and fertilization mode of different fertilizer varieties under local conditions, Now briefing as follows: First, the test method: The test is located in Dingxi Tang Jiabao pilot area. Soil test for the Kawabata Ma soil. Test fertilizer varieties are ammonium nitrate, urea,
