Embodiment 1

[0045] Select Populus euphratica seedling, Populus euphratica seedling plant height 15cm, leaf number 22, plant fresh weight 2.3g, carry out pot experiment, transplant in the middle ten days of a month in April in spring;

[0046] The sandy soil in the pot test is sterilized according to the conventional method, and placed for 15 days, then 10cm is established in the pot, and the diameter is a transplanting hole of 5cm, spread the sandy soil 2mm rich in Glomus moses spores at the bottom of the hole, Slowly rotate on the sandy soil of Glomus spores before the wet Populus euphratica seedling root system transplanting, make Populus euphratica seedling root system stick to sandy soil, the sandy soil of Populus euphratica spores is less than 2mm washing sand, 15-25 spores / ml of sand to ensure that the root system is fully infected;

[0047] Then transplant the Populus euphratica seedlings with sandy soil into the hole in the pot, compact the surrounding soil, and then pour the dil...

Embodiment 2

[0049] Select Populus euphratica seedling or Populus euphratica seed, Populus euphratica seedling plant height 18cm, blade number 30, plant fresh weight 2.5g, carry out pot experiment, transplant at the end of April in spring;

[0050] The sandy soil in the pot test is sterilized by conventional method, and put 18 days, then establish 11cm deep in the basin, diameter is the transplanting hole of 5cm, spreads the sandy soil 3mm that is rich in Glomus moses spores at the bottom of the hole, Slowly rotate the wet Populus euphratica seedling roots in step a before transplanting on the sandy soil of Glomus moses spores, so that the roots of Populus euphratica seedlings stick to sandy soil, the sandy soil of Glomus euphratica spores is less than 2mm washed sand, 15-25 spores / ml sand to ensure root infection;

[0051] Then transplant the Populus euphratica seedlings with sandy soil into the hole in the pot, compact the surrounding soil, and then pour the diluted Hogglund nutrient sol...

Embodiment 3

[0053] Select Populus euphratica seedling, Populus euphratica seedling plant height 20cm, leaf number 35, plant fresh weight 2.6g, carry out pot experiment, transplant at the end of April in spring;

[0054] The sandy soil in the pot test is sterilized by conventional method, and put 20 days, then establish 12cm deep in the basin, diameter is the transplanting hole of 5cm, spreads the sandy soil 3mm that is rich in Glomus moses spores at the bottom of the hole, Slowly rotate the wet Populus euphratica seedling roots in step a before transplanting on the sandy soil of Glomus moses spores, so that the roots of Populus euphratica seedlings stick to sandy soil, the sandy soil of Glomus euphratica spores is less than 2mm washed sand, 15-25 spores / ml sand to ensure root infection;

[0055] Then transplant the Populus euphratica seedlings with sandy soil into the hole in the pot, compact the surrounding soil, and then pour the diluted Hogglund nutrient solution each time to observe t...

Abstract

The invention relates to a method for improving artificial breeding survival rate of populus diversifolia by inoculating arbuscular mycorrhizal fungi. The method comprises the steps of: selecting populus diversifolia sprouts for performing pot experiment, arranging a transplanting hole in the pot, spreading sandy soils rich in glomus mosseae spores at the bottom of the hole, slowly rotating the root systems of populus diversifolia seedlings on the sandy soils of glomus mosseae spores before the transplantation, so that the sandy soils are pasted on the root systems of the populus diversifolia seedlings, transplanting the populus diversifolia seedlings into the hole in the pot, watering a dilute Hoagland nutrient solution every time, and observing the survival rate; or enabling populus diversifolia seeds to absorb water and swell and accelerating germination in an incubator, mixing the populus diversifolia seeds with the sandy soils of glomus mosseae spores, spreading the mixture on a sandy layer surface of a culture bed, and paving a layer of sandy soils rich in glomus mosseae spores under the sandy layer of the culture bed in advance, wherein the root systems are to pass through the sandy soil layer rich in glomus mosseae spores, so that the root systems can be infected. Compared with a control group, the populus diversifolia seedlings obtained by the method are obviously different from the populus diversifolia seedlings in the control group in the growing speed and survival time, particularly in survival rate.

Description

technical field [0001] The invention relates to a method for inoculating arbuscular mycorrhizal fungi to improve the survival rate of artificial seedlings of Populus euphratica. Background technique [0002] Populus euphratica (Populus euphratica) is a tall deciduous tree and a rare shrub of the Salicaceae family. It is an ancient and rare tree species unique to desert areas. Naturally distributed in North Africa, the Middle East, and the river banks and low-humidity saline lands in the arid regions of Northwest my country, it is an important tree species in the desert and semi-desert regions of Northwest my country. Tarim Basin. Populus euphratica has strong drought resistance, salt-alkali tolerance, wind resistance, and sand-fixing capabilities, and is an important stress-resistant germplasm resource in desert oasis areas. [0003] There are large areas of arid areas in the west of my country. Due to the interaction of human irrational production activities and fragile ec...
