春谷的生长发育是由不同阶段组成的动态过程。研究不同阶段的生长特点,对探讨谷子生长发育规律,正确采取栽培措施,有重要的意义。现将我们的研究结果报告如下。一、方法试验是在两种不同栽培条件下进行的:①行距1.2尺,浇水2次(孕穗、抽穗),追肥2次(拔节时每亩施硝铵20斤、过磷酸钙30斤,抽穗前每亩施硝铵15斤),中耕4次(间苗、拔节、孕穗、抽穗),②行距1尺,
Spring Valley growth is composed of different stages of the dynamic process. Study of the growth characteristics of different stages of the development of millet to explore the law, the correct adoption of cultivation measures, of great significance. Now report our findings as follows. First, the method test is carried out in two different cultivation conditions: ① row spacing 1.2 feet, watering 2 times (booting, heading), top dressing 2 times (20 kg of ammonium nitrate per acre on jointing, 30 kg of superphosphate, Before heading 15 acres of ammonium nitrate per acre), cultivating 4 times (Miao, jointing, booting, heading), ② line spacing 1 foot,
