Method for prolonging green period of Sedum lineare Thunb in roof planting

Abstract

The invention discloses a method for prolonging a green period of Sedum lineare Thunb in roof planting, and belongs to the technical field of plant cultivation. The method includes the following steps: removing a part, 1-1.5 cm above a root ground, of Sedum lineare Thunb when the Sedum lineare Thunb gradually enters a withered stage in the middle ten days of November, and retaining a part under a position, 1-1.5 cm above a root ground, of the Sedum lineare Thunb, wherein the retained part includes buds of the Sedum lineare Thunb; applying a nitrogenous fertilizer and monopotassium phosphate; spraying the Sedum lineare Thunb with a plant growth regulator, and spraying the Sedum lineare Thunb with water; and continuously spraying the Sedum lineare Thunb with a plant anti-freezing agent in 3-7 before frost or cold wave for 2 times every 8-11 days. The method can allow the green coverage rate of a roof with the Sedum lineare Thunb to reach above 95%, can achieve roof greening in all year round, can improve urban landscape and an ecological environment, can effectively improve the air quality, and can remedy greening margins and defects in the withered stage of the Sedum lineare Thunb.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for planting S. argentina on the roof to prolong the green period.

[0004] Plants have their growth habits and growth cycles with the changes of the four seasons. Withering is the growth habit of S. japonica. S. japonica will gradually enter the withering period in mid-November, and will gradually germinate until the next spring. During this period, the roof The performance of S. japonica planted in greening is weakened. In view of the lack of greening of S. japonica planted on the roof in this season, a method of planting S. japonica on the roof to prolong the green period is invented. It is the best way to make up for the shortage of S. important
