Safe overwintering method of castor-oil plants

Abstract

The invention discloses a safe overwintering method of castor-oil plants and relates to the technical field of agricultural planting. The method comprises the measures of fertilizing for strengthening plants, watering for resisting cold, winding straws and films for preserving heat, earthing up for antifreezing, relieving films and removing sprouting and has the effects of strengthening the plants, resisting cold, preserving heat, antifreezing, sprouting, strengthening seedlings, and the like. The method can improve the output, reduce the production cost, increase the income of planting the castor-oil plants and is suitable for the application in areas with minimum temperature within 0-10 DEG C in winter.

Description

technical field The invention relates to the technical field of agricultural planting, in particular to a method for safe overwintering of castor plants. Background technique Castor is very sensitive to low temperature, especially to freezing damage. Seedlings will freeze to death at -0.8°C to 1°C, and adult plants will be exposed to continuous frost (-1°C to 3°C), most of the leaves will wither due to frost damage, and even some branches and the upper part of the main stem dead. Therefore, castor is an annual crop in areas where the winter temperature is lower than -3°C, while it is a perennial crop in southern areas (where the winter temperature is above 0°C). At present, most of castor plantation in my country is mainly annual. Although castor planting in the southern region can achieve regenerative cultivation, the next year is no longer sown, and the regeneration seedlings are directly used for production. During the overwintering process, the castor plant suffers sev...

Problems solved by technology

At present, most castor plantations in my country are mainly annuals. Although castor plants in the southern region can achieve regenerative cultivation, they will no longer be sown in the next year and will directly use regenerated seedlings for production. In the process of overwintering, the castor plant suffered serious freezing damage, which made the emergence rate of the second year's regenerated seedlings low and the seedlings were weak, resulting in low yield
