Embodiment 1

[0030] (a) Selection of spraying period: select the late stage of plant stubble;

[0031] (b) Herbicide selection: the effective ingredient ratio of sethenoxydim and quizalofop-p-ethyl is 112.5:31.6g / hm 2 Configured as a mixed solution;

[0032] (c) Selection of environmental conditions: choose spraying in the evening to ensure that there is no strong wind or strong light during spraying, and there is no precipitation for 12 hours before and after spraying.

[0033] (d) Pesticide application: use the stem and leaf spray method, according to the amount of water 30kg / 667m 2 The standard preparation liquid medicine, carries out the uniform spray of stem and leaf with 2L quantitative sprayer.

[0034] On the basis of the above scheme, the traditional 30-day fresh weight control effect was used to evaluate the control effect. The effects of the present invention can be further reflected by the data in Table 1.

Embodiment 2

[0038] (a) Selection of spraying period: select the late stage of plant stubble;

[0039] (b) Herbicide selection: the effective ingredient ratio of sethenoxydim and quizalofop-p-ethyl is 56.25:31.6g / hm 2 Configured as a mixed solution;

[0040] (c) Selection of environmental conditions: choose spraying in the evening to ensure that there is no strong wind or strong light during spraying, and there is no precipitation for 12 hours before and after spraying.

[0041] (d) Pesticide application: use the stem and leaf spray method, according to the amount of water 30kg / 667m 2 The standard preparation liquid medicine, carries out the uniform spray of stem and leaf with 2L quantitative sprayer.

[0042] On the basis of the above scheme, the traditional 30-day fresh weight control effect was used to evaluate the control effect. The effects of the present invention can be further reflected by the data in Table 1.

[0043] From the above data, it can be seen that by the method of t...

Abstract

The invention discloses a method for controlling the spread of achnatherum splendens T.. The chemical prevention and removal method is safe and efficient and can be used for preventing and removing achnatherum splendens T.. According to the method, the sensitivity difference of different grassland plants to sethoxydim and quizalofop-p-ethyl is utilized in cooperation with pesticide application inthe green returning period or the late plant formation and stumping period, and correspondingly the spraying concentration and the compatibility ratio which have an obvious prevention effect on achnatherum splendens T. but have little influence on the growth and development of other gramineous grassland plants around achnatherum splendens T. are screened out. It is discovered by the method that byspraying sethoxydim and quizalofop-p-ethyl according to the effective component ratio of 112.5:31.6 (g / hm<2>), an obvious prevention and removal effect is achieved on achnatherum splendens T., and the prevention effect on achnatherum splendens T. with certain fresh weight in 30 days reaches 97.97%.

Description

technical field [0001] The invention relates to the field of harmful plant control, in particular to a method for controlling the spread of Achnatherum splendens. Background technique [0002] Achnatherum splendens T. is a perennial grass, which is widely distributed in Inner Mongolia, Xinjiang, Qinghai-Tibet Plateau and Hebei in my country. Achnatherum splendens is a good forage grass for livestock when it is young; after many years of growth, the stems and leaves are rough and tough, the quality is not high, and it is difficult for livestock to feed. Therefore, the old Achnatherum splendens beach has become an important area for natural grassland improvement. At present, the occurrence area of ​​Achnatherum splendens is still expanding, seriously endangering the ecological balance of the grassland. [0003] Achnatherum splendens has the characteristics of high seed yield, high reproduction coefficient, tall plants, strong root system and continuous distribution, so manua...
