Herbicide fertilizer granules and method for preparing same

The invention discloses herbicide fertilizer granules and a method for preparing the same. The granules mainly comprise the following components in percentage by weight: 0.1 to 0.3 percent of butachlor, 0.01 to 3 percent of bensulfuron, 5 to 20 percent of coating agent, 6 to 15 percent of adhesives and 59 to 88 percent of NPK compound fertilizer, wherein the active ingredients of the NPK compoundfertilizer accounts for 25 to 52.8 percent of total weight of the fertilizer granules, and the coating agent is soft clay or low-grade celatom. The method for preparing the granules comprises the following steps of: mixing the adhesives with the NPK compound fertilizer and granulating the mixtures with a granulator; dissolving the butachlor and the bensulfuron in organic solvents and diluting thesolution; spraying the diluted solution onto the surface of the granules; coating the granules with the coating agent; and screening the granules to prepare the granules with a grain diameter between1.0 and 4.75mm. The granules have the advantages of low production cost, no pollution, harm or smell, strong adsorption capacity, excellent release effect, no environmental pollution, double functions of weeding and improving utilization rate of fertilizer efficiency, and capacity of controlling annual weed growth in seedlings-throwing fields of paddy rice.

Bionic cultivation method of gentiana straminea maxim

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.

Topramezone, nicosulfuron and atrazine compounded dispersible oil-based suspension agent and preparation method thereof

Relating to the technical field of corn field annual weed control, the invention provides a topramezone, nicosulfuron and atrazine compounded dispersible oil-based suspension agent and a preparation method thereof. The compounded dispersible oil-based suspension agent is prepared from 1.5 parts of topramezone, 4.5 parts of nicosulfuron, 22 parts of atrazine, 3 parts of fatty alcohol polyoxyethylene ether, 5 parts of styrylphenol polyoxyethylene ether, 0.5 part of xanthan gum, 0.3 part of sodium benzoate, 0.5 part of a defoaming agent and 62.7 parts of deionized water. The preparation method includes: pumping the raw materials into a preparation kettle to conduct mixing, then performing primary grinding by a colloid mill, and conducting fine grinding by a sand mill, carrying out sampling analysis, and when the sample is qualified, conducting filtering, metering, packaging and warehousing. According to the invention, the topramezone, nicosulfuron and atrazine compounded dispersible oil-based suspension agent can achieve an obvious synergistic action range when topramezone, nicosulfuron and atrazine are compounded in a ratio of 1.5:4.5:22 to a concentration of 28%, while preparations formed by mixing in other ratios cannot achieve the obvious synergistic action range.
