- 摘要:
- 根据2003 、2004 年两年的气温观测和水稻各生育内的重量数据, 通过气温对水稻生育模型的影响研究, 初步试验结果表明:积温的不同直接影响水稻干重S 型曲线的拐点, 拐点时间主要在 7 月中旬到8 月中旬, 此时的作物干物质增长速度最快;抽穗、开花、灌浆期温度的变化对水稻的影响大;积温的变化与源(叶)的变化呈正相关, 与库(穗)的变化呈负相关;随着积温的减少, 育苗播种和插秧均推迟, 而穗分化、抽穗和成熟提前。
- Abstract:
- According to the weight data of the rice within the every grow th time and the air temperature o bse rv ation betw een 2003 and 2004 year , through the re search that the air temperature af fect the grow th modle of rice , The primary test resul t has indicated :the accumulated temperature dif fe rence af fect directly S curve inf lexion w hich is dry w eight of rice. The inf lexion t ime most ly appear betw een the middle of sev enth month and the middle o f eig hth mo nth. In thi s time , dry substance of crop the most rapidly increase. The temperature chang e will be able to affect g reatly that the rice tassel and blossom and g rout. The accumulated temperature and source (leaf) chang e i s posi tive inte rf ix. The accumulated temperature and storeroom (tassel) change i s negat ive interf ix. According as the accumulated temperature decrease , i t w ill be postpone to seed and to rear y oung plant and to t ransplant , it w ill be advanced that the tassel of rice is po larization and the rice tassel and the rice i s g row n up.
