specific Embodiment approach 1

[0012] Specific embodiment one: a kind of reed rhizome budding optimal water and salt threshold value cultivation method of this embodiment is to carry out according to the following steps:

[0013] 1. Collection of reed rhizomes in the wild: During the budding period of plant rhizomes in the middle and late April of each year, sample points with uniform seedling growth in inland or seaside reed swamps are selected, and the rhizomes are excavated through small patches to reach horizontal rhizomes. The best digging depth is 20-30cm. After digging the rhizomes, put them in a black plastic bag, avoid sunlight, and spray water;

[0014] 2. Treatment of reed rhizomes: wash the excavated reed rhizomes, cut off the above-ground parts, keep the underground rhizomes as cultivation materials, select healthy rhizomes with a diameter of 4-7mm, and cut them into 20cm long sections to ensure that each Each segment has at least 2 nodes, and obtains the reed rhizome to be cultivated;

[0015...

specific Embodiment approach 2

[0018] Embodiment 2: This embodiment differs from Embodiment 1 in that: the optimum digging depth described in step 1 is 25 cm. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0019] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: the aboveground part described in step 2 includes aboveground stems, shoots and leaves. Others are the same as in the first or second embodiment.

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...
