Quick reproduction method for coniferae Chinese tamarisk at the yellow river estuary

Abstract

The invention relates to a fast reproduction method of Yellow River Mouth coniferae tamarisk, which relates to a technical method for quickly reproducing novel nursery breeds in an agroforestry system with high efficiency. The method mainly solves the problems that the salt tolerance of the newly cultured seedlings of the novel breeds is too low, the novel breed resources are few, the sticking reproduction coefficient is low, the cycle is long, the green survival rate in the direct transplanting of large seedlings by cutting the roots is low, etc. The Yellow River Mouth coniferae tamarisk is a newly found high-grade varied tamarisk which is leafy and dark green, has long green period, is salt and alkali tolerant and similar to coniferae, can substitute coniferae for greening, and has very few wild resources. The technology of the invention takes commonly seen congeneric resources as grafting stock which is transplanted to containers after the stump grafting of novel breed grafts for the technical portfolio of culturing green nursery stock. The technical method can quickly apply the Yellow River Mouth coniferae tamarisk in the afforestation in saline-alkali, arid desert areas and coastal mudflat.

Description

1. Technical field [0001] The technology of the invention relates to a technical method for rapidly and efficiently propagating new varieties of seedlings in the agriculture and forestry system. Specifically, it relates to a technical method for cultivating Yellow River estuary pines, cypresses and tamarisks by grafting seedlings and container seedlings. 2. Background technology [0002] my country's saline-alkali, arid deserts and coastal tidal flats are relatively large and widely distributed. Most of these areas have poor soil, sparse vegetation, and lack of suitable plant species. Tamarix is ​​a deep-rooted, drought-tolerant, and water-loving secret salt plant. Tamarix is ​​one of the rare tree species that can survive in these areas without changing the soil. Therefore, Tamarix is ​​a tree species that must be vigorously developed in the above areas where vegetation protection and afforestation are difficult. Therefore, cultivating new varieties of these rare tree sp...

AI Technical Summary

Problems solved by technology

Tamarix is ​​a deep-rooted plant with very few lateral roots. The above two transplanting methods leave most of the root system of Tamarix in situ, and only keep a very limited main root for transplanting. It is difficult to achieve a balance between the water consumption and water supply for the growth of the final seedlings in a short period of time, so the survival rate is not high
