The invention relates to a cultivation method of plateau plants, in particular to a bionic cultivation method of gentiana straminea maxim. The method comprises the following steps of: (1) selecting a gentiana straminea maxim planting base; (2) selecting land and treating soil; (3) preparing seeds; (4) planting; (5) building a meshy fence around the planting base when planting the gentiana straminea maxim in pastoral regions at a higher altitude; suppressing weeds as well as preventing and controlling rodents; and overwintering; and (6), harvesting and primarily processing medicinal herbs. Compared with the traditional gentiana planting method, the bionic cultivation method of the gentiana straminea maxim has the advantages that: 1. the incidence rate of annual weeds in the soil with the depth of less than 10cm can be reduced without ploughing (non-tillage) and stirring the soil when planting, thereby saving the cost; 2. the weeding control is carried out before planting by utilizing biopesticide herbicides with short residue longevity so as to suppress perennial weeds, the gentiana is easy to germinate under the overshading and water-retention of withered and yellow weeds, and the germination speed of the germinate is faster than that of the conventional method at cold areas; and 3. the mechanical cutting is adopted for weeding without pollution, thereby saving the weeding cost.

The invention relates to a weeding composition containing florasulam and triazines. The weeding composition containing florasulam and triazines is characterized by containing 1 to 60 percent of active ingredient A florasulam, 1 to 60 percent of active ingredient B, aids and other excipients, wherein the active ingredient B is one of triazines weedicides such as metribuzin, terbutryn and atrazine; and the weeding composition can be prepared into wettable powder, water dispersible granules, a suspending agent, microemulsion and water emulsion. The weeding composition is used for preventing and controlling annual weed in the wheatland.

The invention provides a herbicide, which relates to the field of production technology of pesticides. Active components of the herbicide comprise benzothiazole oxadiazon and atrazine, and a suspending agent or a wettable power serves as a product dosage form. The herbicide comprises, by weight, 1-25% of benzothiazole oxadiazon, 1-40% of atrazine, 2-25% of an auxiliary agent and 10-96% of a filling material. The herbicide has the advantages of high-efficiency and broad-spectrum weeding performance, is mainly applied to annual weed control in corn fields and exerts no harmful effect on crops.

The invention discloses a weeding composition containing penoxsulam and pyribenzoxim. The active ingredients of the weeding composition are penoxsulam, pyribenzoxim, and the other parts of the weeding composition are pesticide auxiliaries, wherein the weight part ratio between penoxsulam and pyribenzoxim in the weeding composition ranges form (1:20) to (20: 1). The weeding composition disclosed by the invention can be prepared into a suspending agent, an oil suspended agent, wettable powder, or water dispersible granules according to application requirements, and can be used for preventing and eliminating annual weed in a paddy field. The weeding composition has the advantages that the paddy field weed preventing and eliminating effect is remarkably higher than that of each single agent; the dosage can be reduced effectively; the drug resistance of weed can be delayed.

The invention discloses an herbicidal composition which comprises the following active components: cyhalofop-butyl, fluroxypyr-mepthyl and clomazone. Weight ratio of cyhalofop-butyl to fluroxypyr-mepthyl to clomazone is (15-35): (4-8): (6-12). Content of cyhalofop-butyl, fluroxypyr-mepthyl and clomazone in the composition is 5-45%. The herbicidal composition has good synergistic effects on resistant biotypes alkalibarnyard grass. In comparison with the above three single components or a composition of the any two components, the herbicidal composition has advantages as follows: weeding performance is enhanced, dosage of pesticide is reduced, environmental pollution is minimized, and weed resistance is delayed. In addition, the herbicidal composition has good rice security and is a novel pharmaceutical composition for controlling annual weed in paddy field.

The invention relates to a herbicide prepared by binary complex formulation of pendimetalin and oxyfluorfen, and the herbicide is composed of the following ingredients by weight: 33% of the pendimethalin, 5% of the oxyfluorfen, 12% of a synergistic agent, 15% of an emulsifier and 35% of a solvent. The herbicide solves the problems that herbicides in the prior art are not wide in used crops and less in weed killing species, is a high efficient, high-speed contact-killing broad-spectrum herbicide, can control annual weeds, can completely achieve effective control of harm of weed communities in fields by one time of herbicide application, can realize no weed in the whole growth period of crops, is safe to the crops, and has no adverse effects on afterreap crops, the application amount of the herbicide in each mu of field is 24-36g, and the cost of application is reduced by 55 to 42% compared with single use of the pendimethalin and oxyfluorfen.
