叶面宝是一种新型广谱性植物生长调节剂,其对水稻、小麦、瓜果、蔬菜等作物的增产效果已经得到肯定,但对夏玉米的喷施效果研究较少。本研究旨在明确夏玉米喷施叶面宝的最佳时期和最佳剂量,并对其增产原因加以探讨。一、材料与方法试验于1989年在河南省黄泛区农场农科所进行,土质沙壤,土壤肥力中等偏上,底施复合肥(11—15—15S)22.5公斤,尿素
Foliar Po is a new broad-spectrum plant growth regulators, and its yield-increasing effect on crops such as rice, wheat, fruits and vegetables has been affirmed, but the spraying effect on summer maize is less studied. The purpose of this study was to determine the best time and the best dose of foliar application of summer maize and to discuss the reason of increasing yield. First, the material and method test in 1989 in Henan Province, the Pan-Nong District Farm Agronomy, soil sandy soil, soil fertility moderate upper, bottom compound fertilizer (11-15-15S) 22.5 kg, urea

水稻(Oryza sativa L.)是世界上最重要的粮食作物之一。颖壳作为水稻重要的花器官,主要由内稃和外稃构成,它们位于小花结构的外层,提供种子发育所需营养,保护内部器官避免病虫的侵入,更重要的是颖壳的大小或完整性将直接影响水稻产量和品质。因此在水稻中开展颖壳的形态建成及调控机理的研究,具有重要的理论价值和实际的应用前景。前期实验室通过正向遗传学手段筛选到一个温度敏感型水稻突变体,命名为osr
