Abstract
水稻是本省最重要的糧食作物，如何有效地提高其單位面積產量及防止減產損失，實在是一個非常重要的問題。一般來說，增加水稻單位面積產量的方法，不外乎是利用育種方法，育出高產、耐肥、抗倒伏、抗病蟲害等優良品種，推廣給農民種植；另方面，可由改良耕作方法，例如密植，多施化學肥料等方法著手。本省近年來乃積極提倡水稻之『重肥密植』栽培法，以期在有限之耕地面積上，更進一步來提高稻作之單位面積產量。
This research was designed to study the effect of CCC (2-chloroethyltrimethylammonium chloride) on the growth, development, lodging and yield of rice plant. A pot experiment involving two levels of nitrogen (0 and 180 kg/ha) and two levels of CCC (0 and 4 kg/ha a. i.) was carried out under control temperature condition. CCC was sprayed three weeks after transplanting. Effect of CCC on germination was also experimented under control temperature condition before pot experiment was conducted. Additional experiment, which was carried out in field condition, contained four levels of CCC (0, 2, 4, and 6 kg/ha a. i.) three levels of nitrogen (0, 90, and 180 kg/ha) and two application times of CCC (sprayed at 3 and 6 weeks after transplanting). Each treatment replicated 4 times. Factorial randomized complete block design was used in this field experiment.
