Key Points of Winter Management Techniques for Pomelo and a Practical Method Tutorial
Pomelo has a long history of cultivation in our country and is a common fruit in our daily lives. Pomelo generally matures and goes on the market in autumn and winter, and management during this period is extremely important. It determines whether the plants can safely overwinter and is an important guarantee for high and stable pomelo yields the following year, and is closely tied to growers' returns. So how should pomelo be managed in winter? Let's take a look together.
1. Restoring Tree Vigor
After pomelo flowers and sets fruit, the growth of the fruit consumes a large amount of nutrients from the plant. After the fruit is picked, it often causes weakened tree vigor and yellowing and shedding of leaves. Therefore, after harvesting the fruit, tree vigor must be restored in time, otherwise it will affect flower bud development the following year, leading to decreased yield and affecting returns. After harvesting the fruit, fruit-harvest fertilizer should be applied in time to supplement nutrients and promote the plant's tree vigor to recover as quickly as possible. Fruit-harvest fertilizer should mainly be quick-acting compound fertilizer, so that it can be absorbed by the root system as quickly as possible and provide nutrients to the plant.
2. Promoting Flower Bud Differentiation
After harvesting the fruit, due to nutrient deficiency, poor flower bud differentiation often occurs. At this time, measures must be taken to promote flower bud differentiation. There are generally two methods: physical regulation and chemical regulation. Physical regulation methods mainly include girdling the plant, removing winter buds, pruning, root cutting and water control, and so on. This can inhibit new shoot growth, help the branches and leaves accumulate more nutrients, and help flower bud formation and increase the fruit-setting rate the following year. Chemical regulation, on the other hand, involves spraying plant growth regulators to control the plant's hormone balance and promote flower bud differentiation.
3. Applying Winter Fertilizer
To enable the plant to safely overwinter, winter fertilizer should be applied before the winter freeze in combination with deep plowing and soil improvement. Winter fertilizer should mainly be organic fertilizer, combined with phosphorus and potassium fertilizer and other trace elements. Generally, each mature fruiting tree should be given 10-15 jin of organic fertilizer, and this can be increased or decreased accordingly based on the size of the plant, the amount of fruit set, and the growth condition. Fertilization is generally carried out by digging trenches beside the plant's root system and applying the fertilizer.
4. Clearing the Orchard
Clearing the orchard in winter is also a key point in winter management. After a year, a large amount of dead branches and fallen leaves have accumulated on the ground of the pomelo orchard, and many sources of pests and diseases generally overwinter in these dead branches and fallen leaves, waiting to continue harming the plants the following year. Therefore, in winter, the orchard should be comprehensively cleaned, and the dead branches and fallen leaves on the ground should be gathered and burned or buried deeply to reduce overwintering sources of pests and diseases. In addition, some diseased branches and leaves on the plants should also be dealt with together, and then pesticides should be sprayed on the orchard and plants to once again eliminate overwintering sources of pests and diseases.
