How does sunflower pinch its head and explode? Now, one of the best ways to promote sunflower bursting is to pinch and prune the sunflower. First of all, pinch its upper end properly, but don't cut off its side branches. After molding, cut off the part with too long upper end. Let's take a look at how the sunflowers pinch their heads and explode.
How to pinch sunflower heads and burst pots 1 1, and top seedlings?
At the seedling stage of sunflower, you should pinch your head and top the sunflower. Don't cut off the side branches, but pinch the heads on the side branches to promote the growth of the branches at the pinch heads, and finally the flowering ability can be greatly improved. When pinching the head, it is best to do it at one time, so as not to cause multiple damage to the incision node.
2. thinning of adult plants
When the sunflower grows into a healthy plant after topping at seedling stage, it is necessary to cut off all the branches that grow too long and the overgrown side branches, which can improve the ornamental value of the sunflower, and there are more flower buds on the subsequent side branches, which is more likely to explode.
3, pruning tools
It is suggested to use a clean and sharp pruning knife as a tool for pruning sunflower heads. The blade needs to be particularly sharp, so that it can be cut across the board without causing secondary or multiple injuries. After disinfection, the invasion of germs in the incision can be avoided to the greatest extent.
4. Maintenance after cutting
After pruning, it is suggested to put the sunflower in a cool and ventilated environment 1~2 weeks, so that the incision of sunflower can heal itself quickly. Supplementing water, fertilizer and nutrients properly, and nourishing the development of sunflower through bright and sufficient light to make it bloom at flowering stage.
How to pinch the sunflower and explode the pot 2. Sunflower has four steps: pinching the head and exploding the pot.
1, seedling coring
If the sunflower is going to burst, then after each sowing and propagation, when the seedlings grow to about 5cm, the upper end of the sunflower can be properly pinched, and its side branches must not be cut off, otherwise it will hinder the normal growth of the sunflower and make it unable to bloom beautiful flowers.
Step 2 prune into plants
Whenever the sunflower seedlings are denuded and waiting for the plants to grow into plants, then the part with too long upper end and the part with side branches that affect the ornamental value should be cut off every spring, so that the ornamental value of the sunflower can be higher, and a large loss of nutrients can be avoided, and more flowers can be promoted.
3, plastic pruning
If the sunflowers grow densely, then when the sunflowers pinch their heads and burst into pots, they can be thinned, all the withered branches and leaves can be cut off, and then trimmed once, so that soil nutrients can be concentrated and more new buds can be germinated.
4, disinfection treatment
Sunflowers need pruning in the midday sun every time. After pruning, the plants can be disinfected by spraying carbendazim, which can avoid the damage of bacteria to the pruning wounds of plants and make them wither and rot, which is not conducive to the normal growth of sunflowers. They should also be carefully maintained in the sun, and water and fertilizer should not be sprinkled on the leaves.
