How to grow peach trees

Carambola is a fruit that looks like a five-pointed star, which is very attractive and expensive in the market, so it is planted in many areas, so how to grow carambola trees?

1. Choose a place to build a garden

If carambola is planted in mountainous area, it is appropriate to choose southward or southeastward sloping land with irrigated water, good soil quality and small slope. The construction of flat land garden generally requires the excavation of drainage and irrigation ditches, the depth should be determined according to the level of groundwater level, and should be excavated and improved year by year.

2. Planting

The planting specifications of carambola can be 3 × 4 m, 3 × 5 m or 4 × 4 m. Before planting, large planting holes should be dug and sufficient rotten organic matter fertilizer should be applied as base fertilizer. The planting holes in flat orchards are 50 cm deep and 50 cm wide, while those with poor soil quality can be deepened and widened properly. the planting holes in mountain orchards are 1 meter deep and 1 meter wide, and need to be enlarged and improved year by year after planting.

3. Post-planting management techniques.

(1) early shaping: the main goal of carambola is to cultivate a compact round-headed crown. After planting, the young trees are trimmed at 40-50 cm above the ground, and 3-4 evenly distributed main branches are left after shoots. When the main branches are 30-40 cm long, each branch has 2-3 buds. Due to the strong ability of carambola to shoot and branch formation, the carambola is shaped according to this principle, with the increase of the number of branches. A high-yielding crown can be formed after spring planting to the end of the next year. In the process of shaping, the thin and weak branches can be fixed with bamboo branches or string to prevent sagging, and the main branches can be evenly distributed.

(2) Fruit pruning: carambola fruit pruning should be light rather than heavy, and the middle and lower branches should be retained as far as possible, so that they are arranged in layers, branches and leaves are evenly distributed, and the density is moderate. For young and middle-aged fruiting trees, it is appropriate to remove overlord branches, remove some vegetative branches in the upper part of the crown to inhibit growth, and pay attention to cutting thumb thick branches in different directions year by year, so as to maintain strong tree momentum and ensure annual yield. For the old and weak trees, the upper branches of the crown can be cultivated to shade the trunk, and the overgrown branches can be fully used to fill the gap in the crown and renew the old branches.

(3) watering: the distribution of absorbing roots of carambola is shallow, and it is easy to be affected by external conditions, so it should be irrigated in time in the dry and high temperature season, cover the tree plate with weeds, keep the soil moist and reduce the soil temperature to adapt to the normal growth of roots. Carambola roots are not resistant to flooding, which can lead to rotten roots, fallen leaves and fruit for a long time, so the drainage ditch should be dredged and the groundwater level should be lowered before the rainy season. Mountain orchards should expand holes and improve soil in time to prevent stagnant water.

(4) Application of sufficient base fertilizer: carambola fruit tree base fertilizer was applied during burrowing, with 10kg of rotten livestock manure, 1kg of gluten fertilizer and 1kg of calcium superphosphate in each hole. The base fertilizer should be mixed with the soil and backfilled, and then the topsoil should be filled back, and it should be 20 cm above the ground to prevent stagnant water. The fruit trees can be applied in December every year or after the last fruit pruning. Each tree is applied with 1520kg of rotten livestock manure, 1.5kg of gluten fertilizer and 1.5kg of calcium superphosphate, and a circular ditch is dug around the crown drip line.

Generally speaking, carambola is a good species, as long as the site is selected, the cave is dug, and the seedlings are planted in the cave. After successful planting, water and fertilizer, pest control and other work can be done.
