- 摘要:
- 为了选择马铃薯田间除草剂最适施用量，2014年进行一年生杂草药剂防治试验，选用25%砜嘧磺隆水分散粒剂为试验药剂，设置4个浓度梯度及3组对照处理，采用马铃薯苗后茎叶喷雾方法进行试验。结果表明：适宜施药剂量是25%砜嘧磺隆水分散粒剂有效成分15.0～22.5 g`hm-2。施药后30 d，对一年生禾本科杂草稗草的株数防效分别为78.4%～89.7%，鲜重防效分别为82.3%～93.4%；对一年生阔叶杂草的株数防效分别为91.7%～97.5%，鲜重防效分别为95.1%～98.9%，鲜重防效略高于株数防效。对阔叶杂草的防效好于禾本科杂草。建议在禾本科杂草基数较大的田块应采用高剂量或与禾本科除草剂混用。
- Abstract:
- In order to select the most appropriate application amount of herbicide in potato field,control annual weed on potato field test in 2014,taking 25% rimsulfuron water granule as material product by Hanlin biological technology Co.,LTD by Qingdao in Sandong province.In the test,four gradient concentration and three sets of control processing were set up,using potato seedling stem leaf spray after test.Test results showed that the suitable for applying herbicide dosage was 25% sulfone its cycling water dispersible granule effective ingredients 15.0~22.5 grams.hm-2.30 days after applying pesticide,number of annual gramineous weeds control effect was 78.4%~89.7%,fresh weight control effect was 82.3%~93.4%;the number of annual broadleaf weeds control effect was 91.7%~97.5%,fresh weight control effect was 95.1%~98.9%,fresh weight control effect slightly higher than the number of control effect.The broadleaf weed control effect was better than gramineous weeds.Suggestions on the base of gramineous weeds larger field should be used in high doses or with herbicides mixture of cereals.
