Embodiment 1

[0025] A method for transplanting eucommia seedlings in a greenhouse, comprising the steps of:

[0026] S1. Harden the seedlings 5 ​​days before thinning, stop heating the greenhouse during hardening, open the vents of the greenhouse, and control the temperature inside the greenhouse to 25°C and relative humidity to 60%;

[0027] S2. select long to have 2-4 true leaves, and the seedling thinning transplantation of plant spacing less than 5cm;

[0028] S3. According to the weight ratio of plain soil: peat soil: decomposed cow dung=1:1:1, prepare nutrient soil, select a nutrient pot whose depth is 3 cm larger than the length of the main root of the seedlings, put the bottom nutrient soil into the nutrient pot, and the bottom nutrition The thickness of the soil is 1 / 3 of the height of the nutrient bowl;

[0029] S4. Put the seedlings on the bottom nutrient soil of the nutrient pot, and then cover the upper layer of nutrient soil, so that the thickness of the whole nutrient soil ...

Embodiment 2

[0035] A method for transplanting eucommia seedlings in a greenhouse, comprising the steps of:

[0036] S1. Harden the seedlings 7 days before thinning, stop heating the greenhouse during hardening, open the vents of the greenhouse, and control the temperature inside the greenhouse to 30°C and the relative humidity to 75%;

[0037] S2. select long to have 2-4 true leaves, and the seedling thinning transplantation of plant spacing less than 5cm;

[0038] S3. According to the weight ratio of plain soil: peat soil: decomposed cow dung=2:2:1, prepare nutrient soil, select a nutrient pot with a depth 5 cm larger than the length of the main root of the seedlings, put the bottom nutrient soil into the nutrient pot, and the bottom nutrition The thickness of the soil is 1 / 3 of the height of the nutrient bowl;

[0039] S4. Put the seedlings on the bottom nutrient soil of the nutrient pot, and then cover the upper layer of nutrient soil, so that the thickness of the whole nutrient soil ...

Embodiment 3

[0045] A method for transplanting eucommia seedlings in a greenhouse, comprising the steps of:

[0046] S1. Harden the seedlings 6 days before thinning, stop heating the greenhouse during hardening, open the vents of the greenhouse, and control the temperature inside the greenhouse to 27°C and relative humidity to 70%;

[0047] S2. select long to have 2-4 true leaves, and the seedling thinning transplantation of plant spacing less than 5cm;

[0048] S3.

Abstract

The invention discloses a thinning transplanting method of Eucommia ulmoides greenhouse seedlings. The method comprises the following steps of: exercising seedlings, selecting seedlings, preparing nutrition soil, selecting a nutrition pot, transplanting the seedlings after being thinned into the nutrition pot, putting the nutrition pot into the greenhouse at a shady spot where no sunshine radiates directly, keeping the temperature within 23-27 DEG C and the relative moisture of 65-80%, slowing the seedlings, and putting the nutrition pot into a greenhouse with sufficient sunshine and the temperature ranges from 18-26 DEG C and the relative moisture is 70-85% so as to cultivate the seedlings. With the adoption of the method, the large amplitude temperature change if the seedling is transplanted into a large field directly is reduced, a normal growing temperature and a good growing environment are ensured, the seedling slowing time is shortened, sufficient soil nutrition supply is provided, and thus the survival rate is increased.

Description

technical field [0001] The invention relates to the technical field of eucommia planting and cultivation, in particular to a method for thinning and transplanting eucommia seedlings during greenhouse seedling cultivation. Background technique [0002] Eucommia ulmoides is a plant of the genus Eucommia in the Eucommiaceae family. It is a deciduous tree that likes ample sunlight, a mild and humid climate, is hardy to cold, and has no strict requirements on the soil. It can be planted on hills and plains. There are many breeding techniques of Eucommia ulmoides, and the commonly used methods include the following six kinds: seed breeding, cutting breeding, root tiller breeding, grafting seedling breeding, layering breeding and tissue culture of Eucommia ulmoides. [0003] Because sowing seedlings is conducive to mass production of seedlings, and can more stably retain the genetic characteristics of tree species, seedlings have strong stress resistance and developed root systems,...
