小麦的分蘖成穗规律,在豫西的丘陵旱薄地已有资料,而在旱肥地则缺乏研究,为了探索豫西丘陵旱肥地小麦分蘖成穗规律,给制定旱作小麦的栽培管理措施提供依据,我们利用适合在旱肥地种植的小麦品种洛阳29A,于1984～1985年度,在渑池县农科所进行了该项研究。一、研究方法试验地为红粘土,肥力较高,没有灌溉条件,前茬小麦,亩产225公斤。据化验,土壤有机质为0.9827％,全氮0.1394％,碱解氮为74.22PPm,速效磷14.23PPm,速效钾171.4PPm。播种前,每亩施厩肥2500公斤,碳酸氢铵25公斤,钙镁磷肥25公斤,耕地三次。播种时土壤墒情良好,
In order to explore the law of tillering and tillering of wheat in dry land in the west of Henan province, the cultivation and management of dry-land wheat was put forward To provide the basis, we use the suitable Luoyang 29A wheat variety planted in dry land, in 1984 to 1985, the Mianchi County Agricultural Research conducted. First, the research methods to test the red clay, high fertility, no irrigation conditions, the former crop of wheat, 225 kg per mu. According to the test, soil organic matter was 0.9827%, total nitrogen 0.1394%, alkali hydrolysis nitrogen was 74.22PPm, available phosphorus 14.23PPm, available potassium 171.4PPm. Before sowing, per mu of manure 2500 kg, ammonium bicarbonate 25 kg, 25 kg of calcium magnesium phosphate, cultivated three times. Soil moisture when sowing is good,
