Problems solved by technology

Li Zhaohui made a systematic and in-depth study on the cutting propagation technology of Qingtan from the perspective of hormone concentration, cutting position, and different ear picking time. Using IBA to treat the cuttings can make the rooting rate reach 84%, but the treatment method he used is only for experiments. Research, and the research method is cumbersome, time-consuming and labor-intensive, and is not suitable for large-scale and factory production

Embodiment 1

[0023] 1. Selection and preparation of cuttings: On July 6, the healthy, pest-free, 2-year-old green sandalwood branches were collected as cuttings. The pruning method for the branches used for cuttings is: cut the upper end of the cutting branch 1-1.5cm above the first node, and cut the lower end of the branch 0.5-1cm below the node, leaving 2 leaflets on each branch , cut off the first half of each small leaf, and make the average length of the branches 10-12cm, to obtain cutting branches, and set aside;

[0024] 2. Seedbed establishment and cutting matrix preparation: the transplanting bed is built with high borders, weeds are removed, and the land is leveled, 20-30cm of river sand is covered on the soil layer as the cutting matrix. The width of the transplanting bed is 1.0-1.2 meters. Drainage ditches are excavated in between, and the cutting matrix is ​​sterilized with 800 times of carbendazim 24 hours before the cutting for subsequent use;

[0025] 3. Cutting method: Be...

Embodiment 2

[0031] Except that the rooting powder is selected from ABT1, the concentration is 250, 500, 1000mg / L, and the cuttings are soaked respectively for 2, 4, 6, and 8 minutes before cutting, instead of spraying the rooting powder solution to the seedbed, the rest of the operations are the same as in Example 1, 2 months After statistics result, the highest survival rate is 30%, the lowest survival rate is 10%, obviously lower than the survival rate of embodiment 1.

Embodiment 3

[0033] Except that the rooting powder is selected from ABT1, the concentration is 250, 500, 1000mg / L, and the cuttings are soaked respectively for 5, 7, 9, and 11 minutes before cutting, instead of spraying the rooting powder solution to the seedbed, the rest of the operations are the same as in Example 1, 2 months After statistical result, the highest survival rate is 45%, and the lowest survival rate is 10%, obviously lower than the survival rate of embodiment 1.

Abstract

The invention discloses a method for industrialized cutting seedling culture of Pteroceltis tatarinowii Maxim. According to the method, current-year branches of a tree 2-5 years old are selected as cuttings and sheared, so that the average length of the branches ranges from 10 cm to 12 cm, and the branches are planted in a cutting medium; the cuttings are planted and sufficiently watered, a powerful rooting raw powder solution with the concentration being 220-280 mg/L is sprayed to a seedbed with a sprayer, the sprayed solution covers the whole bed surface, and then, seedling management is performed. The technical requirement of the method is simple, Pteroceltis tatarinowii Maxim can be quickly bred in a large area, the cuttage survival rate of Pteroceltis tatarinowii Maxim reaches 93%, a basis is provided for industrialized seedling raising of Pteroceltis tatarinowii Maxim, and the method has great application and popularization value.

Description

technical field [0001] The invention relates to a method for growing seedlings by plant cuttings, in particular to an efficient and rapid method for growing seedlings by cuttings suitable for industrialization of Pseudomonas chinensis, belonging to the technical field of plant propagation. Background technique [0002] Pteroceltis tatarinowii Maxim, also known as Pteroceltis tatarinowii Maxim, is a unique fiber tree species in China. It is distributed in 19 provinces and regions in China sporadically or in patches. It has strong adaptability and loves calcium. , does not have high requirements on soil, and often grows in the limestone mountain forests by the valleys and streams. It is one of the afforestation tree species in limestone areas. Green sandalwood has multiple uses at the same time: its branch bark and stem bark fibers are the preferred raw materials for making rice paper; the wood is solid, dense, tough, and wear-resistant, and can be used for furniture, farm too...
