Chrysanthemum Cutting Time
As a traditional famous flower in China, cutting chrysanthemum is a key propagation method to extend the blooming period. Mastering the correct cutting time and scientific operation methods can increase the survival rate of new plants to over 90%. This article will systematically analyze the core techniques of chrysanthemum cutting from seasonal selection to operational details.
Analysis of the Best Time for Chrysanthemum Cutting
Spring Best Cutting Period
April to May is the golden period for cutting chrysanthemum, when the day and night temperatures are stable between 15-25℃, and the air humidity is maintained at 60%-70%. The concentration of growth hormones in the plant reaches its peak, the meristem of the branches is active, and the cuttings can form callus tissue within 7-10 days.
Precautions in Other Seasons
For summer cutting, a sunshade net needs to be set up to control the temperature not to exceed 30℃. In autumn and winter, it is recommended to carry out in a greenhouse, keeping the substrate temperature above 18℃. In the rainy season, special attention should be paid to the drainage of the substrate to avoid the decay of cuttings.
Complete Guide to Chrysanthemum Cutting
Selection Standards for High-Quality Cuttings
Select semi-woody branches of the current year with a diameter of 3-5mm. Retain the top 2-3 new leaves, and make a 45° oblique cut at the base to increase the water absorption area. A cut distance of 0.5cm from the node can effectively stimulate the germination of dormant buds.
Substrate Preparation and Disinfection
Mix pearl rock, vermiculite, and peat in a ratio of 1:1:2, and water thoroughly with a 0.3% potassium permanganate solution before use. In intelligent greenhouses, it is recommended to use a mist culture system, which can shorten the rooting time to 2/3 of the conventional method.
Key Points for Scientific Cutting Operations
The insertion depth should be 1/3-1/2 the length of the cutting, with a density of 3×3cm spacing. Use intermittent misting to keep the leaves moist, and water with a root powder solution of 800 times concentration weekly.遮光 70% for the first 10 days, and then gradually increase the light after new roots have emerged.
By precisely controlling time nodes and standardizing operational procedures, the success rate of chrysanthemum cutting can be significantly improved. It is recommended to integrate modern horticultural techniques into traditional methods based on local climatic characteristics to create personalized cutting plans. Regularly observe the status of cuttings and timely adjust temperature and humidity parameters to ensure the cultivation of robust new chrysanthemum plants.
