Comprehensive weed control method in radix bupleuri planting

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.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for comprehensive weed control in Bupleurum bupleuri planting. Background technique [0002] Bupleurum bupleurum is one of the bulk varieties of Chinese medicinal materials in my country. The medicinal part is the dried root of Bupleurum bupleuri or Bupleurum angustifolia. The main component is saikosaponin, followed by phytosterols, calendula alcohol, and a small amount Volatile oil and polysaccharide have analgesic, antipyretic, antitussive, anti-inflammatory, anti-pathogen, anti-ulcer effects. Bupleurum is found in most parts of my country, with Henan, Hebei, Shaanxi, Shanxi, Gansu, Inner Mongolia, Qinghai, Xinjiang and other places as the main distribution areas. . [0003] In 2020, relevant market data show that the demand for Bupleurum bupleurum will rise to 10,000 tons, with an annual planting area of ​​800,000 mu and a total output of 8,000 tons. Th...

AI Technical Summary

Problems solved by technology

However, the current planting area of ​​Bupleurum bupleurum in Hubei is only over 10,000 mu, which is far from market expectations. One of the core factors leading to low planting activity is the difficulty of weed control

In Hubei, Bupleurum bupleurum has a long germination cycle and slow growth at the seedling stage, which leads to the growth of weeds in the field, which leads to increased labor input and reduced yield benefits, which restricts the widespread promotion of Bupleurum bupleurum planting
