Description

Simmondsia chinensis cultivation seedbed and seedling cultivation method thereof

Technical Field

The invention relates to the technical field of planting, in particular to a cultivation seedbed of Simmondsia chinensis and a seedling cultivation method thereof.

Background

Simmondsia chinensis is a perennial evergreen shrub, a male and female alloplastic plant and wind-borne pollination originally produced in the southwest desert of the United states, the root of the Simmondsia chinensis can penetrate into the ground for more than ten meters, the age of the tree can reach about 200 years, and the Simmondsia chinensis is called desert killer. The Jojoba is treasure, and its leaves, stems and fruits have wide application and high economic value. The jojoba seed oil has the characteristics of high temperature resistance, high pressure resistance and corrosion resistance, and is the only substitute of sperm oil of sperm whale at present. The oil is widely used in the fields of aviation, aerospace, precision machinery, chemical engineering, cosmetics and the like. In the early 80 s of the 20 th century, the price of jojoba oil was greatly increased due to the discovery of its special use in the cosmetic field. The Simmondsia chinensis has strong drought tolerance, so that the Simmondsia chinensis becomes one of preferable plants for ecological remediation in arid and semi-arid regions. All the steps promote the development and research of the artificial seedling raising technology of the Simmondsia chinensis and the introduction test. Since jojoba is originally produced in tropical desert regions and has strict requirements on environmental conditions of the introduction regions, many introduction countries suffer from failures, wherein the growth of seeds to seedling stage is an important link for introduction, and the introduction failure mostly causes various problems in the seedling stage. The current technology is mature cutting breeding technology mainly based on cutting, but the cutting requires excellent properties of a matrix, but the cut Simmondsia chinensis needs a growth and flowering period of nearly 20 years to produce qualified fruits, so that the method has important research significance on how to improve the survival rate of the introduced seedlings and how to shorten the cultivation period.

If the invention is a Simmondsia chinensis seedling method (application number: 03117860X), the invention introduces a seedling method of the bush commonly called jojoba (jojoba) of Simmondsia chinensis, which is characterized in that a series of processes of disinfection, germination acceleration, culture medium preparation, sowing, seedling picking and the like are carried out on seeds of Simmondsia chinensis to breed replantable strong seedlings of Simmondsia chinensis; although the morchella is used as a carrier and is matched with river sand to simulate a growth environment, the humus soil and the decomposed farmyard manure supply nutrition, and the calcium superphosphate provides a phosphorus element source, so that the high survival rate of the Simmondsia chinensis seeds in a seedling development stage and a transplanting stage is ensured; however, the conclusion whether the cultivation period is shortened is not obtained, and the seeding density of the seedlings in the planting stage is fixed, so that 2-3 times of soil-thinning transplanting is generally needed when the seedlings become transplantable seedlings, the plant spacing is controlled, and the operation is very complicated; although a conventional thought of exercising seedlings by controlling the sunlight irradiation intensity from weak to strong is provided, the sunlight irradiation exercising seedlings aim at fixedly planting seedlings, and the seedling exercising effect of the sunlight irradiation exercising seedlings generates light intensity deviation due to the positions of the seedlings, so that the seedling exercising effect is influenced.
