Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of artificial cultivation of mosses, and particularly relates to a system and method for stratified cultivation of Pectinophyllum winter host lateral branch Dicranum scoparium. BACKGROUND

[0002] Gallnut is a kind of gall of aphids of the family Aphididae parasitizing on the leaves of Rhus plants such as Rhus chinensis, Rhus potaninii and Rhus ambigua, stimulating leaf tissue cells to proliferate and swell to form a gall. It is a traditional forest product and export commodity produced mainly in China. Gallnut is not only an important traditional Chinese medicine, but also a main raw material for producing tannic acid, gallic acid and pyrogallic acid and other chemical products, which are widely used in the pharmaceutical, chemical, electronic, mining and food industries. The gallnut produced in China accounts for more than 95% of the world's total output, and is known for its high tannic acid content, high quality and large quantity, and is known as "Chinensis Gallnuts". Gall aphids are divided into 5 genera and 14 species, among which, Pectinophylla chinensis ( Schlechtendalia chinensis Plagiomnium maximoviczii ) is the most widely used species in gallnut production, and the gall formed by it accounts for about 75% of the total gallnut output, and is the most economically valuable gallnut species, playing a decisive role in production.

[0003] Among the many links in gallnut cultivation, the cultivation of winter host moss is particularly important. The growth cycle, uniformity and purity of the winter host moss have a great influence on the subsequent parasitization of gall aphids on the moss. In the current mainstream cultivation method, there have been problems such as long growth cycle, uneven growth, and difficulty in weed control for a long time. Therefore, there is an urgent need for a new method for cultivating winter host moss of gall aphids. SUMMARY

[0004] The present application aims to overcome the shortcomings of the prior art and provides a system and method for stratified cultivation of Pectinophyllum winter host lateral branch Dicranum scoparium, which is an efficient cultivation method for Pectinophyllum winter host lateral branch Dicranum scoparium. Figure 1 Figure 2 The present application aims to overcome the shortcomings of the prior art and provides a system and method for stratified cultivation of Pectinophyllum winter host lateral branch Dicranum scoparium, which is an efficient cultivation method for Pectinophyllum winter host lateral branch Dicranum scoparium.

[0005] The technical scheme of the present application is implemented by the following scheme: a five-fold gall aphid winter host lateral branch Duthiea pectinata layered planting system, comprising a three-layer structure from top to bottom: (1) an active substrate layer: formed by mixing crushed Duthiea pectinata fragments with an organic substrate at a mass ratio of 1:3, the fragments being crushed to 0.6-1.0 cm; (2) a drainage and ventilation layer: composed of inorganic lightweight materials with a particle size of 2-5 mm, the thickness being 0.5 cm; (3) a physical weed control layer: a polypropylene weed control cloth with a grammage of ≥80 g / m2 and a pore size of ≤0.1 mm.

[0006] Preferably, the organic substrate in step (1) comprises at least one of decomposed pine needles and humus.

[0007] Preferably, the inorganic lightweight material in step (2) comprises volcanic rock, ceramic pellets or / and crushed stone.

[0008] The present application also provides a five-fold gall aphid winter host lateral branch Duthiea pectinata mechanized planting method, comprising the following steps: (a) moss body pretreatment: selecting Duthiea pectinata and mechanically crushing it into 0.6-1.0 cm fragments; (b) substrate mixing: uniformly mixing the fragments with an organic substrate at a ratio of 1:3; (c) layered laying: sequentially laying a physical weed control layer, a drainage and ventilation layer and a geotextile fabric on the ground surface; (d) uniform spreading: spreading the mixed substrate on the geotextile fabric at a rate of 500 g / m2.

[0009] Preferably, step (d) is implemented by using a pneumatic spraying device.

[0010] The present application has the following beneficial effects: (1) weed control: the double barrier (weed control cloth + lightweight substrate layer) greatly reduces the occurrence rate of weeds; (2) rapid turfing: the crushed moss body has increased germination points, uniform growth and a short growth cycle; (3) improved survival rate: the layered structure avoids water accumulation and root rot, greatly improving the survival rate.
