红花草在我县种植时间长,面积大,单产也较高。但是,由于用法不当,肥效来得慢,使早稻迟发,遇上阴雨低温的年份,还容易导致赤枯病的发生。因此,早稻产量往往不高。 为了充分发挥红花草的肥效,花桥区花桥大队农科所坚持实践第一的观点,1974年采取不同的翻压方法,进行对比试验。他们在一块肥力一致的长形田块里安排了四个不同的处理:一是干整,即在翻压红花草时不灌水,犁后晒两天耙细,再过两天灌水整第二次;二是晒蔫水整,即把红花草割起撒开 Red flowers planted in my county a long time, area, yield is higher. However, due to improper use, fertilizer efficiency is slow, delayed early rice, rainy, rainy days, but also easily lead to the emergence of the disease. Therefore, the yield of early rice is often not high. In order to give full play to the effectiveness of Honghua Cao, Huaqiao Huanqiao Brigade agricultural practice adhere to the first point of view, in 1974 to take a different method of turning pressure, the comparative test. They arranged four different treatments in a field of consistent fertility: first, they were dry, that is, they did not irrigate the red flowers when they were turned over, they were sun dried for two days after the plow, and then poured the whole second for two days Times; second, drying the whole water, that is cut from the flowers bloom
