Problems solved by technology

The problem of pests and diseases in the seedling stage of Coral grass has been rarely reported. During the many years of seedling cultivation, there have been different degrees of pests and diseases occurring almost every year. In the early summer in southern my country, the temperature is high and the humidity is high, Coral grass is easy to induce fungal black mold; In the early winter season, the temperature is low and the humidity is high, and the grass coral is easy to induce anthracnose, which will endanger the growth of the grass coral seedlings. In severe cases, the grass coral seedlings will die, the seedling rate of the grass coral seedlings is low, and the economic benefits are low.

Embodiment 1

[0012] A method for preventing and controlling diseases and insect pests of grass coral seedlings. Seedlings are grown in a sunshade greenhouse. During the seedling raising process, the nursery ground is inspected every day. When the surface soil of the nursery ground is dry and whitish, it is watered to keep the soil around the root system of the seedlings moist and there is no water accumulation on the surface of the seedbed. ;

[0013] In the early stage of black mold disease, use 46% copper hydroxide water-dispersible granules and 50% chlorobromoisocyanuric acid soluble powder to mix at a weight ratio of 1:1.5, add water to dilute to 1000 times, and spray every 6 days Once, spray 2 times in a row.

[0014] In the early stage of anthrax, mix 20ml of 25% prochloraz EC with every 15g of 50% chlorobromoisocyanuric acid soluble powder, add water to dilute to 800 times of liquid, spray once every 6 days, and spray continuously Apply 2 times.

Embodiment 2

[0016] A method for preventing and controlling diseases and insect pests of grass coral seedlings. Seedlings are grown in a sunshade greenhouse. During the seedling raising process, the nursery ground is inspected every day. When the surface soil of the nursery ground is dry and whitish, it is watered to keep the soil around the root system of the seedlings moist and there is no water accumulation on the surface of the seedbed. ;

[0017] In the early stage of black mold disease, use 46% copper hydroxide water dispersible granules and 50% chlorobromoisocyanuric acid soluble powder to mix at a weight ratio of 1:1.5, add water to dilute to 1100 times, and spray every 8 days Once, spray 3 times in a row.

[0018] In the early stage of anthrax onset, mix 20ml of 25% prochloraz EC with 15g of 50% chlorobromoisocyanuric acid soluble powder, add water to dilute to 900 times, spray once every 8 days, and spray continuously Apply 3 times.

Abstract

The invention discloses a sarcandra glabra seedling stage disease and insect pest prevention method and relates to the technical field of disease and insect pest prevention. The method includes cultivating seedling in a shaded greenhouse, watering during the seedling stage when the surface soil is observed to be in dried and whitish states so as to allow the soil surround the seedling roots to be moist constantly and no water to accumulate on the surface of a seedbed; spraying drug in the initial stages of black leaf mold and anthracnose for eradication. Compared with the prior art, the sarcandra glabra seedling stage disease and insect pest prevention method has the advantages that soil moisture is proper, damping off and bakanae disease are prevented, and seedling disease resistant capability of the seedlings can be improved; disasters are found out in early stages and can be eradicated, and seedling rate and economic efficiency of seedlings can be improved.

Description

technical field [0001] The invention relates to the technical field of disease and insect pest control, in particular to a method for preventing and treating plant diseases and insect pests in the grass coral seedling stage. Background technique [0002] Grass coral is a broad-spectrum Chinese herbal medicine. With the continuous development of development and utilization, the market demand has increased sharply. At present, wild grass coral resources are becoming increasingly exhausted and can no longer meet market demand. Therefore, artificial planting has been carried out in various places, and standardized planting has been established. The base requires artificial seedling cultivation. Grass coral is usually sown in spring. After careful management, the seedling height can reach 10 cm to 15 cm in December, and it can be transplanted. The problem of pests and diseases in the seedling stage of Coral grass has been rarely reported. During the many years of seedling cultiva...
