Medicinal composition and method for preventing and controlling growth of moss in fritillaria planting greenhouse

Abstract

The invention provides a medicinal composition for preventing and controlling moss. The medicinal composition is formed by uniformly mixing 0.1-10 parts by weight of copper sulfate and 1-50 parts by weight of fructus cnidii water extract. The medicinal composition is mainly used for removing moss on a soil surface or in a pool, and the effect of the medicinal composition is superior to that of single copper sulfate and prometryn. The invention also provides a method for preventing and controlling growth of moss in a fritillaria planting greenhouse. The method comprises the following steps: keeping ventilation in the greenhouse, and illuminating for 1-2 hours every other day; mixing the copper sulfate and the fructus cnidii water extract, adding water into the mixture so as to prepare a medicinal liquid; spraying the medicinal liquid in a dosage of 500-800ml per square meter on the soil surface in the fritillaria planting greenhouse. The medicinal composition is small in dosage and durable in drug effect, cannot cause hazard to the environment, and can be used for overcoming the defect of drug residues of existing chemicals; meanwhile, the method has the advantages of simplicity in operation, safety in use and exact curative effect.

Description

technical field [0001] The invention belongs to the technical field of agricultural medicines, and in particular relates to a pharmaceutical composition and a method for preventing and controlling the growth of moss in a greenhouse for planting fritillary fritillaria. Background technique [0002] Moss includes Spirogyra, Double Star Algae, Transplatinum, etc., which is a general term for filamentous green algae. Most of the moss starts to reproduce and grow in spring. In the early stage, it is attached to the seedling field, the bottom of the pool or the surface of the dark and moist soil like hair. The moss adheres to the seedling field, which seriously hinders the growth of the seedlings, and even causes the seedlings to fall and rot. Moss attached to the bottom of the pool will affect the normal growth of fish, shrimp and crabs, damage their physique, and at the same time induce various diseases, thereby changing the water quality and polluting the water source. Moss a...

Problems solved by technology

The effect of copper sulfate on killing moss is faster, and the time is short and fast. The usual dosage is 0.5-0.8g / m 2 , but the greater the dosage of this product, the more toxic it is to the surrounding vegetation and the organisms in the pool, and it is easy to cause pollution to the bottom, so it should be used with caution for shrimps and crabs in water

Chlorine dioxide, 2,2-dibromo-3-nitropropionamide, and promethazin are all chemical drugs, and they all have different toxic and side effects when used, and there are problems of drug residues

It contains active ingredients, which can release a specific enzyme in the water body, control the cell physiological activities of cyanobacteria and kill cyanobacteria without affecting other organisms and water quality in the water body, but the product's ability to act on the soil surface is not greatly decreased

Although plant ash has a certain control effect on moss, plant ash is only suitable for sunny days, not suitable for cloudy and rainy weather, and it needs to fully cover the moss, but it cannot achieve a comprehensive control effect on the soil surface where other plants are planted.
