Embodiment 1

[0020] In the early winter season, from late November to mid-December, when the outdoor minimum temperature reaches -3°C and the aboveground part of Fujian Guanyin rosette is completely withered, clean up the dead leaves and sundries around the rosette, and then use a concentration of more than 300ppm The germazol disinfected the rosette and the soil around the rosette; and then covered the rosette of the Fujian Guanyinzuo rosette with the prepared covering [sawdust: peat soil (2:1, volume ratio)], and the covering thickness was about 8 ~ 10cm. Cover a thin layer of soil around the accumulated substrate, and then spray the covered mixed substrate with water to prevent the substrate from being blown away by the wind. After pouring water, ensure that the thickness of the covered substrate is greater than 5cm. In winter, depending on the weather conditions and the humidity of the covering substrate, spray water from time to time to moisturize and prevent the substrate from blowin...

Embodiment 2

[0023] In the early winter season, from late November to mid-December, when the outdoor minimum temperature reaches -3°C and the aboveground part of Fujian Guanyin rosette is completely withered, clean up the dead leaves and sundries around the rosette, and then use a concentration of more than 300ppm The germazol disinfected the rosette and the soil around the rosette; and then covered the rosette of the Fujian Guanyinzuo rosette with the prepared covering [sawdust: peat soil (2:1, volume ratio)], and the covering thickness was about 5~7cm. Cover the piled substrate with a thin layer of soil, and then spray the covered mixed substrate with water to prevent the substrate from being blown away by the wind. After pouring water, ensure that the thickness of the covered substrate is greater than 3cm. In winter, depending on the weather conditions and the humidity of the covering substrate, spray water from time to time to moisturize and prevent the substrate from blowing off. Gene...

Embodiment 3

[0025] Implementation Example 3: Controlled Experiment

[0026] From late November to mid-December in the early winter season, when the outdoor minimum temperature reaches -3°C, after the aboveground part of the Fujian Avalokitesvara is completely withered, remove the dead leaves around the rosette of the Fujian Avalokitesvara planted in the same place as in Example (1). Clean up debris and other debris, and then disinfect the rosette and the soil around the rosette with a concentration of 300ppm carbendazim; then cover the rosette of the Fujian Guanyin rosette with dried pure sawdust, and the covering thickness is about 10cm from the top of the rosette. Cover the piled substrate with a thin layer of soil, and then spray the covered pure sawdust substrate with water to prevent the sawdust from being blown away by the wind. After pouring water, ensure that the thickness of the covered substrate is greater than 5cm. In winter, depending on the weather conditions and the humidity...

Abstract

The invention relates to a protective overwintering method for Fujian angiopteris lygodiifolia rosenst in cold districts in winter. The method comprises the following steps of: clearing withered branches and leaves around the Fujian angiopteris lygodiifolia rosenst when the temperature is reduced to 3 DEG C below zero in winter, sterilizing the rosenst and the surrounding soil thereof, and covering the rosenst by using a prepared mulch; and performing winter management, clearing the mulch on the rosenst when the temperature is stabilized at 5 DEG C below zero in next spring, so that the rosenst is germinated and grown and can overwinter safely by a covering protection method. The method can ensure that the Fujian angiopteris lygodiifolia rosenst can overwinter safely and can normally germinate and grow in next spring, the grown quantity is high, and the plants are grown robustly. The preparation of the coverage matrix is simple; and the operating method is simple, convenient, feasible and strong in operability, has the characteristics of low investment, high overwintering survival rate, early plant germination and high growth quantity in next year, and is a reliable mode of safe overwintering after the Fujian angiopteris lygodiifolia rosenst is migrated northwards. Meanwhile, the method provides reference for open field culture and safe overwintering after similar large tropical ferns are migrated northwards, and has high popularization value.

Description

technical field [0001] The invention relates to a method for protecting Fujian Avalokitesvara from overwintering in the Nanjing area on the northern edge of the subtropical zone, in particular to a method for protecting the overwintering by covering the rhizomes with mulch after the leaves wither. Background technique [0002] Fujian Avalokitesvara is a plant of the genus Avalokitesvara in the family Avalokitesvara. It is a magnificent and tall ornamental fern among ferns. Fujian Guanyin seat lotus is characterized by its tall plant type, thick and erect petiole, wide pinnate leaves, and dark green leaf color. The thick fleshy rhizome protrudes from the soil surface, and the remaining fleshy stipules are rosette-shaped, which is quite peculiar and has high ornamental value. Fujian Guanyin lotus is native to South China and Southwest China in the south of the subtropical zone, and is planted in major botanical gardens. Its wild plants are mostly distributed in ravines, vall...
