How to grow carambola planting methods and matters needing attention

At present, there are abandoned fields and hillsides in many places. People often want to make use of the abandoned land. Just want to plant some saplings. Carambola is a familiar fruit, its fruit is very beautiful, people plant carambola seedlings. So, how to plant carambola seedlings? Is carambola seedlings expensive? The following editor is going to talk about some operation methods and matters needing attention in planting.

How to grow carambola

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. 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, 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.

Planting methods and matters needing attention of carambola

1. Fertilizer for promoting shoots and strong shoots and promoting flowers: from March to April, compound fertilizer 0.2kg / plant, urea 0.1kg / plant, manure 10kg / plant / plant, fruit fertilizer: fertilizer for fruit protection was applied during June ~ July when thumb size and pedicel sagging began to be applied, each plant was treated with rotten organic fertilizer (according to ∶ superphosphate ∶ human feces and urine = 1 ∶ 2 ∶ 100retting) 25kg / 30kg.

2. Fertilizer for promoting fruit and promoting flower: fertilizer for promoting fruit and promoting flower is applied after August, the type and amount of fertilizer is the same as that for fruit protection, fertilizer for promoting maturity: fertilizer for promoting fruit ripening is applied before fruit ripening, 10 grams of urea is applied per plant.

3. Overwintering fertilizer: heavy fertilizer is applied in December, mainly organic fertilizer, which is the key fertilizer of the year, accounting for more than 25% of the total amount of fertilizer applied throughout the year, which plays an important role in enhancing tree potential and cold resistance, reducing fallen leaves and withered branches in winter, and increasing next year's yield.

4. Four seasons sweet carambola has the habit of early fruiting, which is usually planted in the year and harvested at the end of the year, but in the initial stage, there are many open spaces between plants and rows, and carambola is afraid of the hot sun, which requires a semi-overcast and humid environment, so it is appropriate to plant papaya, bananas, vegetables, beans and other crops reasonably.

Disease and pest control of carambola

1. Anthracnose, harm: carambola anthracnose only harms carambola fruit, mostly occurs in ripening period, wound can cause disease during storage and transportation. Prevention and treatment: thorough elimination. Deeply buried diseased fruit and small fruit on the tree and fallen fruit and rotten fruit on the ground. Fruit damage should be minimized in harvesting and shipping. In the orchard with serious disease, Bordeaux solution (1 kg of copper sulfate, 1.2 kg of cooked lime, 200 kg of water) or 600 times of copper oxychloride was sprayed in the small fruit stage, once every 10 days and 3 times in a row. Clear the garden in winter.

2. Red spot of carambola is only harmful to leaves and is a fungal disease. At first, the damaged leaves produced very small yellow spots, and then gradually expanded into a circle. Prevention and treatment: strengthen management, enhance tree potential, improve disease resistance. Remove the fallen leaves in winter or early spring and concentrate on burning and ploughing the soil surface.

Cultivated varieties of carambola

1. Malaysian sweet carambola: Malaysian sweet carambola has tall plants, fast growth, high fruiting rate, crispy residue juice and sweet taste, with a single fruit weight of 200kg / 300g, long oval fruit with 5 edges, thick fruit edges, edible rate of 96%, excellent quality and resistance to storage and transportation.

2. American red carambola: American red carambola is similar to Malaysian carambola, with cylindrical tree shape, slightly hard and crisp leaflets, pink long leaves, purplish red inflorescence, single fruit weighs 150g to 250g, and good fresh quality.

Through the above introduction to the poplar seedling planting method, do you know how to plant it? Be sure to pay attention to the matters needing attention in the planting process. Do not plant blindly, that way, not only will not raise very well, but also will make the saplings wither. So, do you understand?
