Description

Ecological interplanting method for blackberrylily rhizome and fructus aurantii

Technical Field

The invention relates to a planting method of traditional Chinese medicinal materials, in particular to an ecological interplanting method of blackberrykiky rhizome and bitter orange, and belongs to the technical field of planting of traditional Chinese medicinal materials.

Background

The belamcanda chinensis is a perennial herb of belamcanda of Iridaceae, the rhizome is irregular and blocky, obliquely extending, yellow or tawny, most of fibrous roots are yellowish, and the stem is upright. The blackberry lily is warm and sunny in favor, drought and cold resistant, has low requirements on soil, can be cultivated in hillside dry land, is good in sandy loam with the advantages of being fertile, loose, high in terrain and good in drainage, is suitable for neutral loam or slightly alkaline soil, is forbidden for low-lying land and saline-alkali land, and is divided into two kinds of propagation: one is seed propagation and the other is rhizome propagation, and the overground part of the blackberry lily needs to be regularly inhibited from growing in order to promote the growth of the rhizome in the planting process of the blackberry lily. In the prior art, nutrients are intensively supplied to rootstock growth mainly by timely picking the shoots or spraying pesticides when the blackberry lily shoots and blooms, however, the method still causes the planted blackberry lily to have small heads due to improper control of overground part growth, increases the health and safety problems of use due to possible pesticide residues, and simultaneously often causes root rot phenomenon due to waterlogging in the planting process of the blackberry lily to influence the growth and the quality of the blackberry lily.

The bitter orange is a nearly ripe fruit of Citrus aurantium and its cultivar of Rutaceae, is slightly cold in nature, bitter in taste, pungent and sour, and mainly comprises volatile oil, alkaloids, flavonoids and coumarins, wherein the volatile oil, flavonoids and alkaloids are mainly effective components and have the effects of regulating qi, relieving epigastric distention, activating stagnancy and relieving distension, and modern researches show that the bitter orange has the effects of regulating gastrointestinal motility, reducing blood fat, reducing blood sugar, benefiting gallbladder and removing calculus, resisting tumors, resisting allergy and the like. The fructus aurantii is planted on hills, low mountainous areas, rivers and lakes along banks with sufficient sunlight and warm and humid climate, and has seed propagation and layering propagation, wherein the seed propagation needs 10 years for fruiting, and the layering propagation can bear the fruits only about 5 years, but has shallow root systems and weak cold resistance and wind resistance.

In addition, in the prior art, the blackberrylily rhizome and the bitter orange are planted separately and have no influence on each other, and if the planting of the blackberrylily rhizome and the bitter orange can be organically combined together, the land utilization rate can be effectively improved, and the economic benefit can be increased.
