How to manage kiwifruit during the flowering and fruiting period? Latest key points explained

Kiwifruit is a fruit that most people like. April to May is exactly the flowering and fruiting period of kiwifruit. At this time, management measures have a great impact on kiwifruit, so attention should be paid. So how should kiwifruit be managed during the flowering and fruiting period? Let's learn about it together.

1. Flowering period management

1. Flower thinning

Kiwifruit flowers have a high fruit-setting rate and tend to bear fruit under normal climate. If there is a large fruit load and more fruit drop, nutrient consumption will be excessive, which will seriously reduce fruit yield and quality. Therefore, flowering period management aims at high yield, stable yield and high quality. First, flower thinning should be carried out. When the fruiting branch grows to more than 50 cm, the flower buds can open. At this time, the flower thinning method is to thin the sparse middle and outer sides, that is, remove the weak buds at the base and top of the fruiting branch, as well as poorly developed flower buds on the same inflorescence.

2. Supplementary pollination

In order to improve the fruit-setting rate and increase yield, supplementary pollination can be carried out. Supplementary pollination is generally carried out on sunny mornings. Generally, each orchard is pollinated 3-4 times, once every 1-2 days. There are many methods of supplementary pollination, and the common three are hand pollination, bee pollination and pollinator pollination. Hand pollination is to collect male flowers that have just opened that morning, gently smear the stamens of the male flowers onto the stigmas of the female flowers. Each male flower can pollinate 7~8 female flowers; bee pollination is to place bees in the orchard. Generally, a 2-mu kiwifruit orchard should have 1 box of bees, with no less than 30,000 bees per box; pollinator pollination is to load pollen into a syringe-contact special kiwifruit pollinator, dip it on one flower, and gently dip it on the stigma of the female flower.

2. Management after fruit setting

1. Fruit thinning

If kiwifruit bears too much fruit, the plant's nutrition cannot keep up, which will cause a large number of fruits to grow poorly. Therefore, timely thin out some deformed fruits, small fruits and diseased or weak fruits to save nutrients and promote the growth of other fruits. In addition, if the fruit load exceeds the target number of fruits to be retained, remove the fruits at the base or tip of the fruiting branch to ensure tree balance.

2. Apply fruit-strengthening fertilizer well

Fruit growth and development require a large amount of nutrients. Insufficient tree nutrition will not only cause poor fruit growth, but also cause premature aging and death of the plant. Therefore, fruit-strengthening fertilizer must be applied well. For fruit-strengthening fertilizer, decomposed farmyard manure can be selected as base fertilizer. Kiwifruit growth requires relatively high chlorine elements, so chlorine-based compound fertilizer can also be used, and potassium chloride can be applied more in topdressing.

3. Fruit bagging

After bagging the fruit, it can avoid sunburn, prevent dust and pesticide pollution, reduce fruit drop, extend storage time, and improve fruit appearance, thereby increasing commercial value. It is recommended to choose paper bags with good air permeability, low water absorption and soft texture. The bagging time should be grasped well. If bagging is too early, it is easy to damage the stems, affect fruit growth and form low yield. If bagging is too late, the effect is not obvious. Generally, bagging can be done after flowering, and bagging should be stopped about 25 days after flowering.
