Idesia root section atomizing culture device

Technical Field

The utility model relates to an idesia root section atomizing culture device.

Background

Idesia is an indigenous woody oil tree species, and fruits of the idesia are high in oil content and rich in unsaturated fatty acid and linoleic acid essential to human bodies; the idesia has the characteristics of good yield, attractive tree shape, strong adaptability, high growth speed, good tree material quality and the like, and can be widely applied to environmental protection greening and the preparation of biodiesel and high-quality edible oil, so that the idesia is an economic tree species with high carbon sink and high added value.

Idesia is grown in deciduous broadleaf forest or needle broadleaf mixed forest in low mountain area with altitude of 400-2500 m. From month 5 in 2013, idesia is listed as one of more than 30 tree species of arbor and shrub capable of large-scale cultivation in national forest resource biomass energy development planning (2011-2020) issued by the national forestry agency. The idesia has the advantages of fast growth, strong environmental adaptability, early resistance and barren resistance. The trunk is straight, has excellent material quality, and can be used as paper pulp and building materials; the pulp and the seeds of idesia are high in oil content, wherein the pulp contains 43.6% of oil, and the seeds contain 22.4% -25.9% of oil, so that edible oil or biodiesel can be refined. Can also be used as raw materials for extracting linoleic acid preparation and preparing soap, paint and oil paint; in addition, idesia tree forms are attractive, the flower color is yellow-green, red fruits are tired to form strings of grapes, and the tree is an excellent tree species for returning to forests and urban greening. Therefore, idesia polycarpa is used as a multipurpose tree species, has high potential development and utilization value, and can be developed into a biodiesel raw material tree species.

The existing artificial cultivation of idesia is mainly concentrated in Guizhou, hubei, sichuan, yunnan, henan, shaanxi and other provinces. As a suitable cultivation area of idesia, the planting scale of idesia reaches 100 ten thousand acres in 2025 years by Guizhou, and the development of the idesia industry in full province is greatly promoted. At present, idesia is mostly propagated by seeds, and the requirements of fine variety and strong seedlings cannot be met due to the low germination rate of the seeds and uneven quality of seedlings; meanwhile, the tree species is a hermaphroditic plant, the fruits of the female plant have higher ornamental value, the female and male plants are mixed in sowing and seedling raising, the female and male plants are not clearly separated, and the excellent plants of the female plant or the male plant can be selected for mass directional propagation by a asexual propagation method. Asexual propagation can well retain the excellent characters of female parent, early setting and increase the yield per unit area. Asexual propagation comprises grafting, cutting, tissue culture and the like, wherein root cutting is one of cutting. The asexual propagation modes of idesia are beneficial and disadvantageous, grafting is limited by the influence of the quantity of stocks, high-quality scions and the like, industrial popularization cannot be carried out on a large scale, and seedlings which are grafted and survived are also easily affected by strong wind and the like to obtain grafting seedling rate; the related technologies of stem cutting and tissue culture are not mature enough, and the high-quality development of idesia industry is seriously affected. Under natural conditions, the idesia polycarpa has stronger root tillering capability and developed root system, and the development of asexual propagation technology is developed by taking the excellent plant root section of idesia polycarpa as a material, so that the idesia polycarpa is an effective way for rapidly promoting asexual propagation of idesia polycarpa. However, at present, reports on the aspect of developing asexual propagation by taking idesia root segments as materials are mainly focused on embedding the root segments in a matrix, so that the defects of rooting, long germination time and the like exist, and the rapid development of idesia industry is seriously hindered.

The prior art about idesia root section propagation comprises the following steps:

1. a root section propagation method of female idesia seedlings (application number: CN 201711461192.6) discloses: the root systems of the idesia mother plants are all taken out and cut into small sections according to the length of 5 cm; cutting and selecting a PC hollow plate greenhouse containing cutting matrixes; the cutting matrix adopts turf with the volume ratio: vermiculite: perlite = 2:1: 0.5. The root section seedling of the utility model is derived from the vegetative organ of the mother plant, can keep the excellent characteristics of the mother plant, and can obtain a large number of female idesia polycarpa seedlings; the female strain of the idesia polycarpa transplanted in the field can reach 100%, the yield of the idesia polycarpa is ensured, and the industrial development of the idesia polycarpa on a large scale is realized. However, the method has weak operability, is not favorable for observing the rooting condition of idesia root sections, has low resource utilization rate, and can not find out whether the root sections are polluted or have the conditions of diseases and insect pests and the like in time.

2. A root section propagation method of an arrow (application number: CN 202111642928.6) discloses: comprising the following steps: (1) pretreatment of root segments: cutting an arrow root into 1.5-2.5 cm or 3.5-4.5 cm root sections, soaking the wound with 70% carbendazim 1000 times liquid for 30 min, and rinsing with clear water to obtain pretreated root sections; (2) root segment induction: removing the dried parts of the pretreatment root sections, selecting the pretreatment root sections with bud points, and directly transplanting the pretreatment root sections to a nutrition pot or a seedbed; the pretreatment root section without bud point is soaked by NAA of 0.4-0.6 mg/L for 2-4 h and then is transplanted to a nutrition pot or a seedbed independently. However, the method is unfavorable for fully exposing the idesia root segments to enough oxygen, and the idesia root segments are easy to be in a flooded stress state.

3. Root section propagation method of Phytolacca americana (application number: CN 202010940248.1) discloses: comprises pretreating Phytolacca americana to obtain America Liu Genduan; sterilizing the pretreated american Liu Genduan; the sterilized americans Liu Genduan are embedded in the matrix and the root segments of the americans embedded in the matrix are managed. But occupies space and is costly.
