Problems solved by technology

However, in northern summer (July, August and September), the temperature is extremely high, the light is extremely strong, and the air is dry. Even if grafted and transplanted, the survival rate is very low.

Embodiment 1

[0033] Embodiment 1, cotton test-tube seedling trench transplanting method

[0034] 1. Preparation of trenches and grafts

[0035] 1) Trench digging

[0036] In the summer of July in Yuncheng, Shanxi, a ditch with a length of about 200 cm, a width of 80 cm, and a depth of 100 cm was dug under the shade shed of the Cotton Research Institute of the Shanxi Academy of Agricultural Sciences (under an ordinary rain-proof shade shed). The temperature in the ditch was 25 ℃, the humidity in the trench is about 80%, and the light intensity in the trench is about 1500LX.

[0037] 2), graft

[0038] Select sea-island cotton seedlings with 3-4 true leaves in flower pots as rootstocks, use 50 Zhongmian No. 35 tissue culture regeneration cotton test tube seedlings (use the hypocotyls of Zhongmian 35 sterile seedlings as explants) Tissue culture, the cotton regenerated plants obtained through the embryonic differentiation pathway) are respectively used as scions for grafting, and the cotto...

Embodiment 2

[0048] Embodiment 2, cotton test-tube seedling trench transplanting method

[0049] The method is basically the same as in Example 1, except that 50 Zhongmian No. 35 tissue-cultured regenerated cotton test-tube plantlets are replaced by 30 Simian No. 3 tissue-cultured regenerated cotton test-tube plantlets.

[0050] As a result, 30 test-tube plantlets were grafted in the test, and 18 survived, with a survival rate of 60%.

Abstract

The invention discloses a cotton test tube seedling trench transplanting method which includes the steps: 1) grafting cotton test tube seedlings to obtain grafting seedlings; 2) cultivating the grafting seedlings in trenches covering a shade frame to obtain the grafting seedlings cultivated in the trenches; 3) transferring the grafting seedlings cultivated in the trenches in a ground shade frame to cultivate to obtain the grafting seedlings cultivated in the shade frame; 4) transplanting the grafting seedlings cultivated in the shade frame in large land to achieve transplanting of cotton test tube seedlings. The width of each trench ranges from 50cm to 100cm, and the depth of each trench ranges from 80cm to 120cm. According to the transplanting method, experimental results show under the micro-environmental conditions formed by the trenches, grafting, transplanting and surviving of test tube seedlings are facilitated, and the test tube seedlings can still be transplanted under the conditions of high temperature, high light and air drying in summer in north by the transplanting method.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a ditch transplanting method for cotton test-tube seedlings. Background technique [0002] Tissue-cultured seedlings are collectively referred to as test-tube seedlings or tissue-cultured seedlings. Test-tube seedlings grow in a closed environment with constant temperature, high humidity, low light, and sterility for a long time, which is very different from the external environment. Affected by this environment, cotton test-tube seedlings grow weakly, and the cuticles on the surface of stems and leaves are underdeveloped; the photosynthesis of chloroplasts is poor; the number of stomata in leaves is small, and their activity is poor; Poor resistance. [0003] It is because of the large difference between the internal and external environment and the poor ability of test-tube seedlings to adapt to the external environment. In the dry weather in the north, the survival rate of direc...
