黃振增

摘  要

「秧田半作」,因是秧田雜草之防除,也是水稻栽培上重要之一項工作,掃丹-M、馬上除及草霸王三種藥劑,經65、66年之試驗結果,推荐如下之秧田雜草防除使用方法:床畦做好後,蓋平床面前,每公頃施用30公斤之掃丹-M或馬上除,以木鏝蓋平床面後播種,並繼續保持濕潤狀態3∼5日。或者,秧苗移植前第一期作10天,第二期作5天,每公頃噴施草霸王200倍稀釋液3公升(稗草多時,應於秧苗本葉一葉時排乾床面積水噴施35%思登F-34乳劑2.5公升),均可獲得良好之殺草效果。


A Test on the Nursery Herbicides

T. T. Huang

Summary

        This study had been carried out from 1976 to 1977 in Chia-yi Branch Station of the Tainan District Agricultural Improvement Station.  Three kinds of herbicides were tested, they are: (1) 13% Saturn-M granule. (2) 5% Machete granule and (3) 44.1% Basagram L.  In view of the results obtained in this study, some suggestions could be proposed as follows:

1. Seed bed must be prepared properly before the application of the herbicides.  Ti is required to scatter Saturn-M or Machete granule 30 kg/ha uniformly on the bed.  It is better to smooth the surface of bed before sowing rice seeds and it should keep the soil in moist condition at least 3 to 5 days.

2. It is recommended to spray 200 times diluted solution of Basagram 3 liters per hectare on nursery at the 10th day and the 5th day before transplanting the rice seedlings for the first crop season and the second crop season, respectively.

3. All of those herbicides tested in these experiments gave satisfactory results for weeds control in nursery.
