１９９３～１９９４年，在渭北黄土高原刺槐改造更新幼林地，用４种化学除草剂对刺槐伐桩萌芽和林地杂草防除进行了研究。结果表明：刺槐伐桩萌条防除应在萌条未木质化阶段用低容量喷雾法施药、或在伐桩未萌芽阶段用涂抹法施药，但前者除萌效果最好。节约投资４０．４％～６７．９％，提高工效２．５～４．０倍。喷雾法最适药剂种类及有效剂量为：目的伐桩用１．４ｋｇ／万丛的革甘膦或０．３～０．５ｋｇ／万丛的森革净；非目的伐桩用１．２～３．０ｋｇ／万丛的２，４－Ｄ丁酯或２．１ｋｇ／万丛的革甘群。萌生刺槐分别与油松、华山松、落叶松、杜仲混交幼林地化学除草，应在４月底用有效剂量０．５ｋｇ／ｈｍ２的森草净或２．０ｋｇ／ｈｍ２的２，４－ＤＴ酯，或用０．８ｋｇ／ｈｍ２的革甘膦（杜仲除外）低容量喷雾。除草率达８３．２％～８７．６％，提高工效６０倍，节约投资３８．９％～６０．０％。
From 1993 to 1994, the young locust was reformed in Robinia pseudoacacia on the Loess Plateau of Weibei, and four kinds of chemical herbicides were used to study the sprout of locust cutting and the weed control in the forest. The results showed that the seed germination of Robinia pseudoacacia should be sprayed with low volume spray in the non-lignification stage of sprout, or with the smear method in the stage of non-sprout stump. Saving investment 40.4% ~ 67.9%, improve work efficiency 2.5 ~ 4.0 times. Spray method of the most suitable types of agents and effective doses: purpose of cutting pile with 1.4kg / Wan Cong of or the 0.3 ~ 0.5kg / Wan Sen Senge net; non-purpose cutting pile with 1.2 ~ 3.0kg / Wan Cong 2,4-D butyl ester or 2.1kg / Wan Cong Gu Gan group. Black locust and pine, Huashan pine, Larix gmelinii, Eucommia birch mixed chemical young weeding should be the end of April with an effective dose of 0.5kg / hm2 Sen grass net or 2.0kg / hm2 of 2,4-DT ester, Or with 0.8kg / hm2 of glufosinate (excluding Eucommia) low volume spray. Weeding rate of 83.2% ~ 87.6%, improve work efficiency 60 times, saving investment 38.9% ~ 60.0%.
