籼型杂交水稻几个抗倒伏性状表现
|
摘要
调查了品比试验中35个晚籼杂交水稻品种(组合)的株高、地上部伸长节间长、茎秆干物重及密度、分蘖进程、穴穗数及成穗率、稻穗大小等性状,按倒伏和未倒伏分为两组,并对性状进行对比分析。结果表明,抗倒伏品种(组合)具有植株稍矮、第三伸长节间短、茎秆干物质密度大、分蘖发生早、穴有效穗多、成穗率高等特点。水稻生产中,可通过适宜的栽培措施,充实茎秆质量,促进早生快发,减少外因致倒,增强根基支撑力度,从而防止倒伏发生,避免因倒伏而减产。
35 late indica hybrid rice varieties(combinations) were selected to compare the character including the plant height, the elongation intermode length of aboveground, the stem substance weigh and density, the tillering process, the number of hole ears and head rate and grain size. These varieties(combinations) were divided into two groups according to lodging and lodging resistance, and the characters of these two groups were contrasted. The results showed that, compared with the lodging varieties(combinations), the varieties(combinations) with the resistance to lodging exhibited slightly shorter plant height, the shorter length of the third elongation internode, larger stem substance weigh and density, the earlier tillering, more effective ears and higher head rate, and so on. In rice production, it can avoid the crop failure because of lodging through proper cultivation measures to enrich the stem quality, promote early and quickly tillering, reduce the lodging from external cause and strengthen the foundation support.
