Problems solved by technology

Scholars at home and abroad have also achieved fruitful research results on salt-tolerant poplars, but due to various factors, they have not been cultivated on a large scale. The main reason is the problem of multiplication. The common method of poplar multiplication and cultivation is cutting seedlings. How to screen out tree species with strong stress resistance and adapt to the climate and soil conditions in saline-alkali areas in northern China, and widely promote them It is the key issue in the breeding of salinity-tolerant poplars

Embodiment 1

[0037] a. Preparation of materials for propagation: Fill the culture medium into the nutrient bowl, 30 minutes before filling, first add water to make the water content reach 50% to 70%, and control the filling capacity to 80 pots per square meter; then put the nutrient The bowl is placed in the shed;

[0038] Wherein the matrix is ​​composed of the following materials in parts by weight: 40 parts of peat soil, 25 parts of vermiculite, 20 parts of perlite, 10 parts of mulberry leaf powder, 5 parts of pine needle powder, 3 parts of mycorrhizal fertilizer and 3 parts of superphosphate;

[0039] b. Collection and preservation of cuttings: Select the current year’s branches of saline-alkali-resistant poplar during the dormant period and store them in the overwintering period. The storage method is:

[0040] b01. Choose a shady place with high terrain and good drainage to dig a ditch. The ditch width is 1.5 meters and the depth is generally 60 cm to prevent the temperature in the d...

Abstract

The invention discloses a rapid breeding method of a saline and alkaline resistant poplar. The method comprises the steps including preparation of materials for breeding, collection and storage of a cutting slip, processing of a slip, cutting and management, seedling hardening and transplanting. The cutting slip and the slip are processed by specific cultivation matrix and treatment fluid before cutting. The method is simple in operation and low in cost, the cutting survival rate can reach 98% or higher, the survival rate after cutting and transplantation is high, stress resistance is high, the method can be applied to production directly, and the economical and social values of the method are high.

Description

technical field [0001] The invention relates to the technical field of plant planting, in particular to a method for rapidly propagating saline-alkali resistant poplars. Background technique [0002] With the increasing scarcity of land resources, people pay more and more attention to this special type of saline-alkali land. For a long time, the difficulty of afforestation has always been a long-standing problem in saline-alkali land management. As one of the main tree species for greening, poplar is the most widely distributed and most adaptable tree species in the world. It has the characteristics of fast growth, high quality, and strong adaptability. It is expected to become the main tree species for saline-alkali land transformation and greening. Scholars at home and abroad have also achieved fruitful research results on salt-tolerant poplars, but due to various factors, they have not been cultivated on a large scale. The main reason is the problem of multiplication. Th...
