Problems solved by technology

At present, the methods of weed removal mainly include ① manual removal: the disadvantage is time-consuming and labor-intensive, which promotes the development of weed seeds after loosening the soil, and will damage the newly grown lawn grass; ② chemical control: although the effect is better, However, if the application area is too large, it will affect the growth of turfgrass, and the drug effect will last for a long time, which will affect the use of soil in the future; ③Biological control: it is a method to reduce weeds by using natural enemies, microorganisms or other plants, although the control cost is relatively low It is labor-saving, but it may lead to excessive reproduction of biological control agents, which cannot be controlled

Embodiment 1

[0034] The grass species for testing is Qingdao Zoysia seeds, provided by Shandong Qingdao Haiyuan Lawn Co., Ltd., harvested in the summer of 2018, after soaking seeds in 30wt.% NaOH aqueous solution for 10 minutes to break dormancy, according to the standard germination method ("GB / T2930.4- 2017 Grass Seed Inspection Regulations "Germination Test") to determine the germination rate, the basic information is shown in Table 1.

[0035] Table 1 Basic conditions of Zoysia seed samples tested

[0036]

[0037] Coating material is: binder is sodium carboxymethyl cellulose aqueous solution (mass fraction of sodium carboxymethyl cellulose is divided into 1wt.%, 1.5wt.%); Inert substance is talcum powder and bentonite; Dyeing agent is seed The colors are liquid red and liquid green; the active substance is Shafeng.

[0038] Taking 5g of Qingdao Zoysia seeds as an example, set the working parameter speed of the coating machine to 450rpm-600rpm, and use the above coating formula to ...

Embodiment 2-6

[0045] Embodiment 2-6 is all identical with embodiment 1 for testing herb species, and the difference of coating formula and embodiment 1 is that active substance and consumption thereof are different, specifically as shown in table 2, and according to embodiment 1 The tested grass species were pelletized by the method described above.

Embodiment 1-6、 comparative example 1

[0057] Embodiment 1-6, comparative example 1, comparative example 2 Verification of the effect of pelletized seeds on weed control:

[0058] (1) Soil bed sterilization treatment: add water to the water level before using the autoclave; seal the nutrient soil that needs to be sterilized with a plastic bag, put it into the sterilizer, and close the lid; turn on the power, extinguish The sterilizer starts to work, when the pressure rises to 0.15MPa (121°C), start counting for 30 minutes; when the specified sterilization time is reached, turn off the power, open the vent valve to deflate slowly; when the pressure pointer drops to 0.00MPa, When there is no steam to be discharged from the air release valve, the lid of the pot can be opened to take out the sterilized nutritious soil.

[0059] (2) Cultivate the seeds treated in Examples 1-6, Comparative Example 1, and Comparative Example 2 according to the following method: Mix the nutritious soil and vermiculite obtained in step (1) ...

Abstract

The invention discloses a weed-resistant zoysia seed pellet coating material and a coating method thereof, which belong to the technical field of seed processing. The coating material of the present invention includes a binder, an inert substance and an active substance, and the active substance is one or more of sulfasulfuron-methyl, quinclorac, xiubaigong or zalufeng. The germination rate of the pelletized formula provided by the invention is the same as that of the naked seed, and the growth vigor is better than that of the naked seed. The obtained zoysia seeds have weed resistance, and can efficiently save manpower and material resources in terms of weed control costs.

Description

technical field [0001] The invention belongs to the technical field of seed processing, and in particular relates to a weed-resistant zoysia seed pellet coating material and a coating method thereof. Background technique [0002] Weeds are one of the major factors in lawn establishment and degradation. At present, the methods of weed removal mainly include ① manual removal: the disadvantage is time-consuming and labor-intensive, which promotes the development of weed seeds after loosening the soil, and will damage the newly grown lawn grass; ② chemical control: although the effect is better, However, if the application area is too large, it will affect the growth of turfgrass, and the drug effect will last for a long time, which will affect the use of soil in the future; ③Biological control: it is a method to reduce weeds by using natural enemies, microorganisms or other plants, although the control cost is relatively low It is labor-saving, but it may cause the overgrowth ...
