Insect-resistant root dipping agent for gingko and preparation method thereof

Abstract

The invention discloses an insect-resistant root dipping agent for gingko and belongs to the technical field of seedling root dipping agents. The insect-resistant root dipping agent contains the following components in parts by weight: 10-20 parts of an organophosphorus insecticide, 10-15 parts of a benzimidazole fungicide, 1-2 parts of a GGR6# rooting agent, 20-30 parts of a super absorbent resin, 100-200 parts of sodium carboxymethylcellulose and 500-1000 parts of talcum powder. According to the insect-resistant root dipping agent for gingko, disclosed by the invention, on one hand, a mud layer formed on the surface of the seedling root can protect the root system, and an effect of moisturizing the roots is achieved; on the other hand, hazards of soil insects such as grubs, mole cricketsand wireworms can be prevented and alleviated, and root system growth is facilitated, so that the transplanting survival rate and retention rate of gingko seedlings are improved. Due to the organic combination of seedling mud dipping and control of plant diseases and insect pests, the transplanting survival rate of the gingko seedlings is improved.

Description

technical field [0001] The invention belongs to the technical field of dipping agent for seedling root system, and in particular relates to a seedling anti-insect root dipping agent and a preparation method thereof, which is used for seedling planting, moisturizing seedling root system during transportation and preventing underground pests after transplanting. Background technique [0002] Ginkgo biloba (Ginkgo biloba) is a deciduous tree and is a unique hereditary plant in my country. It contains a large number of chemical substances with pharmacological effects in its body, especially the diterpenoids ginkgolide and flavonoids contained in the leaves, which can improve organ health. Its function of dilating, promoting blood circulation and preventing vascular aging has attracted the attention of the world. Since the 1980s, many countries have successively established special leaf picking gardens for ginkgo. At present, ginkgo leaf-picking gardens are generally established ...

AI Technical Summary

Problems solved by technology

At present, ginkgo leaf-picking gardens are generally established by transplanting and planting 1-2-year-old seedlings in autumn or spring. However, due to the weak growth potential of ginkgo for a period of time after planting, the roots and rhizome junctions are easily affected by grubs, mole crickets, and day lilies. The harm of underground pests will cause damage to the roots of seedlings, the survival rate of seedlings is low, even less than 60%, and the preservation rate is even lower. The uniformity of the ginkgo leaf-picking orchard is poor and the management is inconvenient

[0003] The root system of seedlings dipped in mud can improve the survival rate of seedlings transplanted to a certain extent. In production, it is often used to stir the pastoral soil and water into mud and dip the roots to form a mud layer on the surface of the root system to reduce the evaporation of root water, which has the effect of moisturizing the root system. Low preservation rate due to damage by pests and diseases has no effect
