The purpose of removing the core of kiwifruit is to promote new shoots, inhibit the growth of fruit trees, make nutrients flow downwards, keep buds in the best nutritional state and increase the number of fruiting branches.

What does kiwi fruit mean by picking the heart?

Kerned kiwifruit, also called topping, is a common plastic method. The specific method is to pinch off a part of the front end of the growing branch.

Suitable time for enucleation of kiwifruit

It is best to remove the core of kiwifruit in June in summer, once every two weeks until the end of July, with the main purpose of branching.

Kiwifruit core removal method

When the branches of kiwifruit become fragile and entangled with other objects, they should be pitted. When the new branches grow to 15cm in early spring, the windward branches should be cut off by 3-5cm to reduce the center of gravity and wind damage. Results 3~5 leaves were left at the top of the branch for coring, and 2 leaves were left for coring when the new bud germinated for more than 3 times.

Matters needing attention in removing the core of kiwifruit

When picking kiwi fruit core, be careful not to prune too much, which wastes the nutrition of the tree and causes the new branches on the shelf to be dense. The basal buds are poorly developed, and flower buds cannot be formed, so the seed setting ability is reduced. After picking kiwifruit, the application amount of accelerating germination fertilizer and pre-flowering fertilizer is relatively large, and the fertilization should be combined with nitrogen, phosphorus and potassium, mainly nitrogen and potassium.
