Description

Technical Field

[0001] The invention relates to the technical field of agriculture, and in particular to a granulated formula of Isatis indigotica seeds capable of resisting root diseases and promoting root growth. Background Art

[0002] Isatis tinctoria L. is a perennial herb belonging to the genus Isatis of the family Cruciferae. Its root, called Radix Isatidis, is an important Chinese medicinal material with the effects of clearing away heat and detoxifying, cooling blood and relieving sore throat, and is widely used in the production of Chinese patent medicines and folk treatments. In recent years, with the increasing demand for health and natural medicines, the planting area of ​​Isatis has gradually expanded, but some problems faced in the planting process have also become increasingly prominent. Among them, root disease (diseases caused by fungi) is one of the main obstacles to Isatis cultivation, which seriously affects the growth and development of Isatis and the final yield. In addition, the rooting ability of Isatis seeds is weak and the emergence rate is low, which also leads to an increase in planting costs and unstable yields.

[0003] Root disease is a plant disease caused by a variety of fungi, including common pathogens such as Phytophthora, Fusarium and Rhizoctonia. These fungi are widely present in the soil and can be spread through soil, rainwater, irrigation water, etc., infecting the roots of plants and causing root rot. Root disease not only directly affects the root development of Isatis indigotica, but also causes slow plant growth, yellowing of leaves, and eventually even death. Especially in rainy seasons and low-lying and poorly drained plots, the incidence of root disease is higher, which has a greater impact on planting results.

[0004] Another significant problem of Isatis indigotica seeds is their weak rooting ability. Seed germination and rooting are important stages of plant growth, and the strength of rooting ability directly affects the survival rate of seedlings and the robustness of plants. If the rooting rate of seeds is low, it will not only lead to a decrease in germination rate, but also increase the cost of replanting. In actual planting, improving the rooting ability of Isatis indigotica seeds is the key to improving yield and quality.

[0005] At present, the common methods for treating woad seeds on the market mainly include soaking seeds with chemical agents and mixing seeds with biological agents, but these methods have some limitations. Although chemical agents can effectively kill fungi, they have potential harm to the environment and soil ecosystems. Long-term use can lead to soil compaction and microbial imbalance. Although biological agents are more environmentally friendly, their effects are unstable, greatly affected by environmental factors, and have high costs. Summary of the invention

[0006] The invention provides a root disease-resistant and root growth-promoting Isatis indigotica seed pellet formula, which significantly improves the disease resistance and rooting rate of the seeds by optimizing the formula components and the preparation process.

[0007] The technical scheme adopted by the present invention is: a granulated formula of Isatis indigotica seeds for resisting root diseases and promoting root growth, comprising the following components in parts by weight: 50-60 parts of Isatis indigotica seeds, 5-10 parts of antifungal agents, 3-7 parts of rooting promoters, 8-12 parts of moisturizers, 10-15 parts of nutritional additives, and 5-8 parts of adhesives;

[0008] The pelletized formulation is prepared by the following steps:

[0010] Step 2: Add the rooting promoter and continue stirring to make the rooting promoter evenly adhere to the surface of the seeds;

[0011] Step 3: Add moisturizer and mix thoroughly to ensure that the moisturizer forms a protective film around the seeds;

[0012] Step 4: Add nutritional additives and mix evenly with the seeds;

[0013] Step 5: Add the binder and continue stirring to make all ingredients adhere tightly to the surface of the seeds;

[0014] Step 6: The mixture is sent to a granulator for granulation to form seed pellets with a diameter of 3-5 mm;

[0015] Step 7: Dry the prepared seed pellets and package them after quality inspection.

[0016] As a further improvement of the present invention, the antifungal agent is one or more of carbendazim, thiophanate-methyl and thiram.

[0017] As a further improvement of the present invention, the rooting promoter is one or more of naphthylacetic acid and indolebutyric acid.

[0018] As a further improvement of the present invention, the moisturizing agent is one or more of polyacrylamide, sodium carboxymethyl cellulose, and sodium alginate.

[0019] As a further improvement of the present invention, the nutrient additives include nitrogen, phosphorus, potassium compound fertilizers and trace elements, wherein the weight ratio of nitrogen, phosphorus and potassium is 2:1:2.

[0020] As a further improvement of the present invention, the trace elements include iron, zinc, manganese, copper and boron, and the total weight of the trace elements accounts for 5-10% of the nutritional additive.

[0021] As a further improvement of the present invention, the adhesive is one or more of polyvinyl alcohol, gum arabic, and gelatin.

[0022] As a further improvement of the present invention, the granulator is a rotary granulator, the rotation speed of the granulator is 30-50 rpm, and the granulation time is 10-15 minutes.

[0023] As a further improvement of the present invention, the temperature of the drying treatment is controlled at 40-50° C., and the time is controlled at 2-4 hours.

[0024] The beneficial effects of the present invention are as follows: (1) The granulated formula of the isatis indigotica seeds for resisting root diseases and promoting root growth significantly improves the disease resistance and rooting rate of the isatis indigotica seeds by scientifically proportioning antifungal agents and rooting promoters, and effectively solves the problems of root disease hazards and weak rooting ability faced in the planting process of isatis indigotica.

[0025] (2) The pelletized formula of the present invention uses environmentally friendly materials, is environmentally friendly, will not cause damage to the soil ecosystem, and meets the requirements of sustainable development of modern agriculture; at the same time, the preparation process of the formula is simple and easy, suitable for large-scale production, which is conducive to reducing planting costs and improving economic benefits.
