What to do when kiwi fruit skin turns green? The latest solutions are here
The fruit of the kiwi is brown and yellowish-brown when fully ripe, but some growers find that the skin of their kiwi fruit turns green during cultivation, which also affects the taste of the fruit, lowers its quality, and makes it unsuitable for storage. So what is going on? Let's take a look at Qinnongwang to see the causes and solutions for green kiwi fruit skin.
1. Excessive dense planting
When the planting density is too high, after the tree canopy takes shape, the spaces between plants become small, causing poor air and light penetration for many leaves and trunks, so they cannot get sufficient light conditions, leading to poor growth.
Control method: Plant at a reasonable density, be sure to maintain spacing between plants, and 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 enlargement stage. The fruit does indeed become larger than normal, but this disrupts the normal growth cycle of the fruit, causing it to be oversized yet poor in taste and resulting in green fruit.
Control method: 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 early on to speed up growth, which causes nutrient imbalance in the soil and the fruit trees. In the end, the plants become very tall but bear very little fruit, and it also easily leads to fruit cracking and green fruit.
Control method: Fertilization should not be one-sided; apply fertilizer according to the growth condition of the fruit trees. Nitrogen fertilizer is suitable at the seedling stage, while phosphorus and potassium fertilizer should be applied during the fruit enlargement stage. In addition, combine fertilization with organic fertilizer or farmyard manure to provide the trace elements needed for the growth of the fruit trees.
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 high, the roots of the fruit trees will absorb a large amount of water, causing the fruit to contain more water, making its flavor weaker and resulting in green fruit.
Control method: Strictly control the amount of watering. In the later period, if it is a rainy season, drain water in time to reduce soil moisture, or build a greenhouse to keep off the rain.
The above are the causes and solutions for green kiwi fruit brought to you by Qinnongwang. After reading this, I believe everyone also knows the causes of green kiwi fruit. Take corresponding measures to prevent it, and I hope this can help you.
