Cultivation method of reed rootstock budding with optimal water and salt threshold value

Abstract

The invention relates to a cultivation method of a reed rootstock budding with an optimal water and salt threshold value, and aims at solving the problems that relevant data of rootstock budding cannot be intuitively reflected by environmental factors, a water and salt range suitable for planting reeds cannot be provided for recovery and reconstruction of field degenerative salt marshes in the prior rootstock propagation method. The method comprises the steps of firstly, field reed rootstocks collecting; secondly, reed rootstocks processing; thirdly, cultivation and rootstock budding process detecting. The method is used for the cultivation of the reed rootstocks. The method is convenient to operate, cost-saving, suitable for providing seedlings for the recovery of inland and seaside reedswamps, and of important practical significance and application value.

Description

technical field

[0001] The invention relates to a method for cultivating the optimal water and salt threshold for budding of reed rhizomes. Background technique

[0002] Reed (Phragmites australis) is a perennial rhizome-type grass, which is widely distributed in the world and can be distributed in both freshwater and saltwater swamps. It is one of the main types of herbaceous swamps in my country. Phragmites reed has two propagation methods: seed propagation and branch propagation, but it is a typical clonal plant, and the natural population mainly relies on vegetative propagation to supplement and update. The creeping rhizomes of Phragmites reed are well developed, the root zone can reach several meters in length, and the depth can reach more than 1m below the surface soil.

[0003] Reed has a wide range of economic value: 1. The crude protein content in the vegetative growth period is the highest among grasses, and it is an excellent feed; 2. The reed stems in the mature...
