specific Embodiment approach 1

[0026] Specific embodiment one: the batch transplanting method of Northeast Chinese yew seedlings in the present embodiment is as follows:

[0027] 1. Quality estimation of transplanted seedlings:

[0028] (1) Estimated time: Estimate the quality of seedlings on any day from mid-November to early March of the following year, when the seedlings are still in a dormant state;

[0029] (2), sample selection: Randomly select 20% of the total number from the same batch of yew seedlings ready to be transplanted for quality estimation, and the seedlings used for quality estimation must be of the same seedling age and come from the same set of cultivation method;

[0030] (3), estimation method: pick 4 needles at random from the middle part of the needles area of ​​selected seedlings, the size of the needles can be different but the integrity of each needle must be guaranteed, rinse the needles with distilled water and use Wrapped with a wet paper towel, put it on a glass container, ...

specific Embodiment approach 2

[0043] Specific embodiment two: what this embodiment differs from specific embodiment one is the method for extracting leaves in step one (3): accurately measure the height of the needle leaf area with a ruler, at the position of the intermediate value of the total height, respectively at Pick a complete needle leaf in each of the four directions of east, south, west, and north. When picking, pinch the base of the leaf with tweezers and pull the leaf outward. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0044] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that in step 1 (4), the maximum wavelength of the LED red light-emitting diode is 650 nm, and the light quantum flux density is 1200 μmolm -2 the s -1 . Others are the same as those in the first or second embodiment.

Abstract

The invention discloses a batch transplanting method for taxus cuspidata seedlings, relates to a transplanting method for taxus chinenesis seedlings in cold regions and belongs to the field of taxus cuspidata seedling transplanting. The technical problems that in the prior art, the taxus cuspidata seedlings are low in survival rate of transplanting and poor in growth in the field are solved. The method includes the steps that 1, chlorophyll fluorescence parameters of transplanted seedling quality are estimated; 2, the environmental suitability of seedling transplanting land is investigated and evaluated; 3, the seedlings are transplanted. By the adoption of the experimental method, after three months of transplanting the taxus cuspidata seedlings, the survival rate is 95%, after five months of transplanting, the survival rate is 90%, and compared with other methods, the survival rate of transplanting is increased by 30-50%.

Description

technical field [0001] The invention relates to a method for transplanting yew seedlings in cold regions. Background technique [0002] Northeast yew (Taxuscuspidata), also known as yew and yew, is a precious Tertiary relic tree species distributed in Northeast my country, and a wild endangered plant species under national Class I key protection. Northeast yew is rich in paclitaxel, and its content is at the top level among the five main yew strains in my country. It is an excellent plant material for preparing anticancer drugs. The wild Northeast yew grows in the acidic land zone with cold and humid climate. It likes to be born in moist soil rich in organic matter. Plant height to about 2m. In this regard, people generally adopt the method of artificial planting to breed yew seedlings with high-quality provenance, which can make the yew seedlings grow into ideal specifications in a short period of time, and then transplanted to the wild environment. Due to the difference...
