Embodiment 1

[0049] 1) Test location: Longquan Town, Yiling District, Yichang City, Hubei Province

[0050] 2) Experimental variety: Mishima Bupleurum, which is an annual Bupleurum variety

[0051] 3) Sowing time: October 20, 2019

[0052] 4) Seeding density: 2kg per 667㎡.

[0053] 5) Weed control: In this implementation, multiple weed control programs are designed, see Table 1 for details. The contents of pendimethalin, trifluralin, prometon, oxyfluorfen, and high-efficiency haloxyfop applied in the test group were 33%, 48%, 40%, 21%, and 10.8%, respectively. The dosage of pendimethalin per 667㎡ in 1~5 was 100ml, and the dosage of pendimethalin and trifluralin per 667㎡ in test group 6 were 50ml and 80ml respectively. In the test group, the application dose was 30g per 667㎡, and in the test groups 3-6, the application doses of oxyfluorfen and haloxyfop-methyl were both 40ml and 40ml.

Abstract

The invention discloses a comprehensive weed control method in radix bupleuri planting. The method comprises the following steps: before planting and sowing radix bupleuri, ploughing soil by using a rotary cultivator, conducting weeding through ploughing, and after planting and sowing of radix bupleuri, spraying a sealing agent; after the sealing agent is sprayed on the radix bupleuri, covering the compartment surface; before radix bupleuri seeds germinate and when weeds exist in the field, spraying prometryn wettable powder once with the application amount of 8-20 g per 667 m<2>; after the radix bupleuri completely emerges, observing the field weeds: when a large scale of monocotyledonous weeds appear, applying 2-8 ml of haloxyfop-R-methyl emulsifiable concentrate per 667 m<2>; and when mixed monocotyledonous and dicotyledonous weeds appear and when the radix bupleuri grows to a four-leaf stage or the plant height is greater than or equal to 8 cm, firstly spraying 4-15 ml of oxyfluorfen emulsifiable concentrate and then spraying 3-10 ml of efficient haloxyfop-R-methyl emulsifiable concentrate per 667 m<2>. The weed control effect reaches 90%, the yield of the radix bupleuri can be increased by 20%, and only two working hours are needed.
