Kumquat , as a subtropical evergreen fruit tree, has a cultivation history of more than one thousand years. Its fruit is both sour and sweet, and it has the reputation of " eat lychees when you are hungry and eat kumquats when you are full", which shows how popular it is. In order to grow kumquats well, it is important to learn the planting and management techniques of kumquats trees .

1. Variety selection

There are many varieties of kumquat, divided into sour and sweet types. The sour variety is suitable for deep processing , while the sweet variety is suitable for fresh consumption.

The Yunan seedless yellow peel fruit is oval, orange-red in color, and tender and smooth in texture. The fruit of the large chicken heart yellow peel is heart-shaped, sweet and slightly sour, and is resistant to storage and transportation. The Guangxi seedless kumquat fruit is oblong, tastes sour, and has no seeds or few seeds.

2. Planting site selection

Choose land that is sheltered from the wind and has a small slope. The soil should be fertile, loose and well-drained, avoiding waterlogging or drought.

3. Seedling selection and planting

Choose strong seedlings with a diameter of more than 0.6 cm and a height of 25-35 cm. Dig a hole and weather it. The size of the hole is 1m×1m×0.8m. Apply base fertilizer and then return the soil. The row spacing is 4.0 meters × 3.5 meters. Prune the seedlings and irrigate the roots with water after planting.

4. Management of young trees

Start fertilizing after new shoots emerge, mainly with nitrogen fertilizer, combined with phosphorus, potassium and magnesium fertilizers. Keep the soil moist and avoid overwatering. Pinch off or shorten the trunk to cultivate main branches and branches.

5. Fruit Tree Management

Apply flower fertilizer before and after the Great Cold, apply fruit-strengthening fertilizer before thinning the fruits, and apply autumn shoot fertilizer after harvesting the fruits. Pay attention to drainage during the rainy season and irrigate during the autumn shoot germination period to resist drought. Prune after harvesting the fruit, cultivate the fruiting mother branches, and cut off dead and diseased branches and overcrowded branches. Thin out poor flower spikes, spray gibberellins to increase fruit setting rate, and thin out fruits in late May.

VI. Pest and disease control

Pay attention to diseases such as canker, sooty mold, anthracnose, and root-knot nematodes. Pest control includes psyllids, wax cicadas, leaf miners, aphids, scale insects, etc.

In short, if the above aspects are managed well, the yield and quality of kumquat can be effectively guaranteed.
