Cultivation technology of yellow fruit

Huangpi fruit , also known as Huangpi, Huangpi or Huangdanzi, originated in South China and Southwest China, with a cultivation tradition of more than 1,500 years. This fruit is known as the "treasure of fruits" by the people because of its rich nutritional and medicinal properties, and the fact that it can be made into preserved fruits, jams and other foods. It is widely welcomed by consumers and growers. In Fujian, Guangdong, Guangxi, Yunnan, Sichuan and other regions, the planting area of ​​kumquat is constantly expanding and the development momentum is strong. Let’s learn about the cultivation techniques of kumquat.

1. Garden site selection and preparation

Choose a site that is sheltered from the wind and has a gentle slope, and ensure that the soil has good aeration, sufficient organic matter, and a complete drainage system to support the healthy growth of kumquats.

2. Planting of seedlings

Select strong seedlings with a diameter of more than 0.6 cm, a height of between 25 and 35 cm, upright and with well-developed root systems, and plant them in spring or autumn.

Before planting, dig the tree pit and weather it. The size of each tree pit should be 100 cm × 100 cm × 80 cm. After a period of weathering, apply fertilizer to the tree pit and backfill the soil to promote the healthy growth of seedlings. The row spacing and plant spacing should be controlled at 4.0 meters × 3.5 meters.

When planting, prune the seedlings appropriately to ensure that the root system is spread out. Water thoroughly or apply Sea Elf biostimulant immediately after planting to help the roots take root.

3. Young tree management

Timely fertilization: Fertilization should start after the new shoots appear. Nitrogen fertilizer should be used as the main fertilizer, supplemented with phosphorus, potassium and magnesium fertilizers, and combined with Sea Elf biostimulant. Apply fertilizer once before new shoots grow and once during the greening period to promote the development of new shoots.

Water management: Kumquat grows well in a humid environment, so ensure adequate water supply , but avoid excessive watering to avoid damaging the root system.

Tree shape management: Pinch or shorten the main trunk at a height of 40 to 50 cm to promote the germination of new buds, retain 3 to 4 main branches, and continue to cultivate secondary and tertiary branches in this way to lay the foundation for future yields.

4. Result Tree Management

Fertilization management: Apply fertilizers that promote flower bud differentiation around the Great Cold, mainly organic fertilizers , supplemented with quick-acting fertilizers, and apply through trenching; apply fertilizers that promote fruit growth before thinning the fruit, mainly nitrogen and potassium fertilizers; apply fertilizers that promote autumn shoot growth after harvesting the fruit to help restore tree vigor and promote flower bud differentiation, and pay attention to supplementing phosphorus and zinc. In addition, foliar fertilization should be combined during the flowering and fruiting period, such as spraying sea elf biostimulant.

Water management: The roots of the kumquat are shallow and it likes oxygen. It cannot tolerate drought and is not suitable for waterlogging, so attention should be paid to drainage during the rainy season. After the fruits are harvested, attention should be paid to irrigation during the autumn shoot germination period to resist drought.

Pruning: Prune after harvesting the fruit, leaving two buds at the base of the fruit branch for pruning to promote the growth of autumn shoots and cultivate good fruiting mother branches. When picking fruits from fruiting mother branches, do not use leaf shears, just cut off the fruit clusters. After the fruit is picked, remove dead branches, diseased and insect-infested branches, and overly dense shade branches, and shorten overgrown branches to form an umbrella-shaped crown that is ventilated and light-permeable.

Flower and fruit management: Promote the growth of autumn shoots to cultivate fruiting mother branches; when flowering, remove the underdeveloped side spikes at the base of the spike, retain the middle 2 to 3 side spikes and prune them; spray gibberellins and sea elf biostimulants during the flowering period to increase the fruit set rate and fruit retention; thin the fruits in late May.

5. Disease and pest control

Diseases mainly include canker, sooty mold, anthracnose, root-knot nematodes, etc.; insect pests include psyllids, wax cicadas, leaf miners, aphids, scale insects, etc.

The above is an introduction to the key points of kumquat cultivation techniques. You can formulate a suitable planting plan based on the local geographical environment.
