Reasons for Green Kiwifruit Skin and Solutions

When fully ripe, kiwifruit is brown and yellowish-brown in color, but some growers encounter green kiwifruit skin during cultivation, which also affects the fruit's taste, lowers its quality, and makes it unsuitable for storage. So what is going on? Let's take a look at the reasons for green kiwifruit skin and the solutions below on Qinnongwang.

1. Excessive dense planting

When the planting density is too high, once the tree canopy takes shape, the gaps between plants become small, causing poor air and light penetration through many leaves and trunks. They cannot receive sufficient sunlight, leading to poor growth.

Prevention and control methods: Plant at a reasonable density and be sure to maintain spacing between plants. You can also carry out shaping and pruning at each growth stage of the fruit trees to ensure good air and light penetration. This helps the fruit color up and reduces the occurrence of green fruit.

2. Excessive use of swelling agents

To increase yield, some growers use swelling agents excessively during the fruit expansion period. The fruit does indeed become larger than normal, but this disrupts the fruit's normal growth cycle, resulting in large fruit with poor taste and causing the green fruit phenomenon.

Prevention and control methods: Manage water and fertilizer reasonably, thin flowers and fruit, and use normal methods to achieve high yield and high quality. Try not to use swelling agents, or use as little as possible.

3. Improper fertilization

Nitrogen fertilizer promotes plant growth and is widely used in agriculture. To make fruit trees grow quickly, many people use large amounts of nitrogen fertilizer in the early stage to force growth, causing nutrient imbalance in the soil and fruit trees. In the end, the plants grow tall but bear very little fruit, and it also easily leads to fruit cracking and green fruit.

Prevention and control methods: Fertilization should not be one-sided. Fertilize according to the growth condition of the fruit trees. Nitrogen fertilizer is suitable during the seedling stage, while phosphorus and potassium fertilizer should be applied during the fruit expansion period. In addition, combine fertilization with organic fertilizer or farmyard manure to provide the trace elements needed for fruit tree growth.

4. Irrigation during the fruit ripening and coloring stage

During the ripening and coloring stage, the water requirement is not high. If a large amount of water is applied at this time or the soil moisture is relatively high, the fruit tree roots will absorb a large amount of water, causing the fruit's water content to increase, making its flavor bland and causing green fruit.

Prevention and control methods: Strictly control the amount of watering. In the later stage, if it is the rainy season, drain water promptly to reduce soil moisture, or build a greenhouse to keep off the rain.

The above are the reasons for green kiwifruit and the solutions brought to you by Qinnongwang. After reading this, I believe everyone now knows the reasons for green kiwifruit. Take corresponding measures to prevent it, and I hope this can help you.
