Hydroponically cultured fresh-cut carnations 1. Material preparation
Hydroponics is a common cultivation method for many plants. Hydroponics of carnation can be carried out in April-September of flowering period. First of all, you need to prepare materials, and you need to prepare a clean glass bottle. Then, you can pick healthy branches with flower buds from good-growing carnations, or go directly to the flower shop to buy hydroponic carnations.
2. Branching therapy
After the hydroponic materials of carnation are prepared, the branches of carnation need to be treated. One end of the branch inserted into the water needs to be obliquely cut, 3-4 leaves and buds are left at the upper end of the branch, and all other leaves are cut off, which can increase the success rate of hydroponics and is beneficial to better culture after hydroponics.
Step 3 insert a vase
Most flower lovers don't know how to cultivate fresh-cut carnations in water. When everything is ready, put half the water in the glass bottle and insert the processed branches into the glass bottle to ensure air circulation. If it is normal, the branches can take root and sprout in a month. You can add some beer, sugar, vinegar and other items to promote the growth of carnations.
Carnation culture management. Change water regularly.
When carnation is hydroponically cultivated, it is necessary to change fresh water regularly. If it is not changed for a long time, a large number of bacteria will be produced in the water, which will affect the absorption of minerals in the water by the roots, and finally the carnations will wither and die. Generally, water is changed every half month in spring and autumn, every 10 day in summer and every 20 days in winter.
2. Plenty of sunshine
Carnations like to grow in the sun, so do hydroponic carnations. Carnations can grow better in sufficient sunshine. Carnations should be placed in the shade after each water insertion, and then cultivated in the sun after a month of rooting and germination, so that carnations can grow better, but they can't be cultivated in strong light, so they need to be cultivated in the shade in summer.
3, appropriate pruning
Every time the water of carnation is changed, the rotten roots can be cut off, and all the old branches and diseased branches can be cut off in spring, so that the roots of carnation grow better, the branches and leaves grow more luxuriantly, beautiful flowers bloom, and the ornamental value of carnation is increased.
Three, carnation pest control 1, gray mold
Carnations are prone to gray mold. At the early stage of the disease, gray mold will appear on the branches, buds and flowers of carnation, and then spread to every branch quickly, affecting the ornamental value of carnation, and finally leading to carnation withering and death. If the carnation is found to have gray mold, it is necessary to strengthen management, cut off the pathogen, and then spray 1 1,000 times potassium permanganate aqueous solution or 1 1,000 times prochloraz for control.
2. Starscream
Carnations are also vulnerable to the harm of red spiders. Red spiders will suck the juice from carnations, which will lead to poor growth of carnations, and they will lay eggs on branches in winter, which will harm carnations in the coming year and directly lead to carnations withering and death. If red spider is found, metalaxyl emulsifiable concentrate or 40% dicofol should be sprayed 1000 times.
Conclusion: Through the above introduction, I believe everyone knows the hydroponic methods of fresh-cut carnations, as well as the hydroponic management and pest control of carnations. I hope everyone can hydroponically cultivate beautiful carnations in their lives.
