The solution to the poor coloring of kiwifruit

Kiwifruit is a fruit on the market in autumn, which is rich in vitamin C and tastes sour and sweet, so it is deeply loved by people. During the critical period from August to September, kiwifruit rose in sugar content and coloring, but many farmers reported that their kiwifruit coloring was not good. What should we do? Come and have a look with the editor.

1. Strengthen autumn scissors

For orchards with incomplete summer pruning, thick leaves, dense branches and poor permeability, autumn pruning should be carried out carefully and carefully to increase the ventilation and permeability in the canopy. At the same time, under the premise of not causing sunburn to the fruit, remove the old and diseased leaves in time, let the branches of the shelf surface see light as much as possible, promote the coloring of the fruit, and pay attention to apply anti-corrosion film on the cut after pruning to promote the healing of the cut, so as to prevent germs from getting in.

2. Pick fruit at the right time

There are many varieties of kiwifruit, all kinds of varieties have their advantages and disadvantages, both early-maturing varieties and late-maturing varieties, so their fruit-picking time is also different. If the fruit is picked too early, it will affect the fruit coloring, so the fruit-picking time must be grasped. Generally speaking, kiwifruit takes about 120-150 days to grow, so the general harvest time is from October to November. For example, the harvest time of Qinmei kiwifruit is in the first ten days of November.

3. Balanced fertilization

The growing period of kiwifruit is mainly divided into three stages, in which the early vegetative growth is dominant, when fertilization is mainly nitrogen fertilizer to promote the growth of branches and leaves, while in the middle stage of reproductive growth, fertilization is dominated by phosphorus and potassium fertilizer combined with foliar fertilizer to control the application of nitrogen fertilizer, inhibit vegetative growth and improve fruit setting rate. In the later period, when vegetative growth and reproductive growth go hand in hand, it is necessary to spray Zhuangguotiling to increase the nutrient delivery duct to enhance the amount of nutrient transport and promote coloring.

4. Control moisture

Watering kiwifruit will also affect the fruit coloring, watering should be timely and appropriate during the fruit expansion period, so as to keep the soil from water cut off, in order to increase the weight of single fruit and increase the yield. In the later stage, watering should be controlled to promote sugar accumulation and burns in the fruit. In the later stage of the orchard, little or no watering should be done according to the actual situation, so as to open the light path and help the fruit coloring.
