Embodiment 1

[0044] Such as figure 2 As shown, the present invention provides a greenhouse control system for Populus euphratica improved species, comprising a seedling-growing greenhouse 1 and a seedbed arranged in the seedling-growing greenhouse 1, three faces of the seedling-growing greenhouse 1 are walls, and the seedling-growing greenhouse 1 The other two surfaces of the plant are provided with shading nets and plastic cloths for shading and heat preservation respectively. The seedbed is divided into several independent block areas 2, and each of the independent block areas 2 is laid sequentially from top to bottom. There are thermal insulation sand layer 3, temperature control electric heating layer 4 and seedling raising sand layer 5, on said seedling raising sand layer 5 densely arranged with several nutrition bags 6 for cutting cuttings, said temperature controlling electric heating layer 4 includes equidistant Heating wires 401 arranged at intervals and a temperature controller ...

Embodiment 2

[0058] Such as figure 1 As shown, a cutting rapid propagation method of Populus euphratica improved species comprises the following steps:

[0059] Step 100, collection and preprocessing of cuttings;

[0060] Specifically, the principle of cuttings collection is: collect the annual branches that grow robustly in the upper part of the mother tree, cut the branches into 10-15cm long and 0.3-0.7cm in diameter as cuttings, and each cutting has 3 to 4 Full-bodied buds with a smooth upper cut and at least one full-bodied bud 1cm from the top;

[0061] And the step of the pretreatment of cuttings is, adopt the ABT1# of concentration 100ppm to soak for 6h.

[0062] Step 200: Carry out container-temperature-controlled cutting seedling cultivation for the cuttings, build a seedbed, put the pretreated cuttings into the nutrition bag, and control the temperature and humidity of the seedbed to be within the specified range;

[0063] Most of the traditional container cutting seedlings ar...

Abstract

The embodiment of the invention discloses a cuttage rapid propagation method for populus simonii. The cuttage rapid propagation method comprises the following steps of S100, collecting and pretreatingcuttings; S200, conducting container-temperature control cuttage seedling growing on the cuttings, establishing a seedbed, conducting cuttage on the pretreated cuttings into nutrient bags, and separately controlling the temperature and humidity of the seedbed to designated ranges; S300, transplanting seedlings to a field and establishing a cutting orchard. According to the cuttage rapid propagation method, nutrient soil in the nutrient bags provides necessary nutrient substances for the growth of the cuttings, water storage sponge at the bottom of each nutrient bag makes root taking liquid permeate into the nutrient soil to promote root taking of plants, then a temperature control system and a sprinkling device regulate the temperature and humidity of the seedbed, in the early stage, thetemperature and humidity are increased to a condition adapting to the growth environment of beneficial microorganisms in the soil, and propagation of the beneficial microorganisms is accelerated; through products obtained through metabolism of the microorganisms, the growth of the cuttings is accelerated, the effective microbial community advantages are improved, the purpose of treating bacteria with microorganisms is achieved, the diseases of the cuttings are reduced, and the cuttage survival rate is increased.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of nursery stock cultivation, in particular to a cutting and rapid propagation method of Populus euphratica improved species. Background technique [0002] Populus euphratica, also known as Populus euphratica. It has the characteristics of drought and waterlogging resistance, heat and cold resistance, wind and sand resistance, salt and alkali resistance, and barrenness resistance. It is the most primitive and oldest tree species in the Populus genus. Due to its characteristics, Populus euphratica has become an important windbreak tree species in desert areas, and is the main preferred tree species for afforestation under extremely harsh natural conditions such as deserts and saline-alkali lands. At the same time, Populus euphratica has a very high ornamental value because the leaves turn yellow in autumn and lasts for a long time. However, because Populus euphratica is mainly propa...
