How to plant jackfruit seeds? can pineapple trees be planted in the north?

Jackfruit grows in a tropical climate with high nutritional value and is a very popular fruit. Jackfruit's flesh is wrapped with a core, so some people want to use the pineapple kernel to grow jackfruit, so how to plant it to grow into a jackfruit tree? Can this kind of tree grow in the north? Let's take a look at it in detail.

How to plant jackfruit seeds

1. Garden site selection

Jackfruit likes the warm and humid tropical climate. Not tolerant to cold, the annual average temperature ≥ 21 ℃, the coldest monthly mean temperature ≥ 13 ℃, and the absolute lowest temperature ≥ 0 ℃ are required. Soil requirements are not strict, in the deep soil layer, fertile loose, well-drained acid soil, slightly alkaline clay or sandy loam soil, can grow normally. It is best to cultivate in low hilly land or flat land below 600 meters above sea level.

2. Seed propagation

In the main ripening stage of jackfruit, the dried wrapped fruits with full maturity, normal fruit development and free of diseases and insect pests were selected, washed with clean water, then spread flat on the sand bed to accelerate germination, and covered with fine sand 1cm and 2cm, then covered with a layer of straw, and watered once or twice a day. After about a week, they sprouted and rooting one after another, and when the seedlings had 1 or 2 true leaves, they could be transplanted in separate beds.

3. Budding propagation

Jackfruit seedlings grow to more than 1 cm can be budded, using patch budding method for budding. On the excellent varieties, one-year-old and sunny mature branches are selected as scions, and the scions should be moisturized and stored, preferably with picking and grafting, which can be budded all the year round in Hainan, but the survival rate of bud grafting is higher in the rainy season and tree growing season from April to October. At this time, the rootstock and scion are easy to peel and survive after grafting.

4. Setting up a garden and planting

The row spacing of pineapple plant is 5cm × 6cm × 6cm, 80 cm × 80 cm × 80 cm planting hole is dug, weeds are placed at the bottom of the hole, 0.5 kg of branches and leaves are mixed with lime, then return to 1 layer of topsoil, 30 kg of pond mud, 30 kg of livestock manure and 0.5 kg of phosphate fertilizer. Jackfruit can be planted all the year round, but spring planting (March-April) and autumn planting (September-November) are the best. When planting, the soil in the planting hole should be sorted out to straighten out the seedling root system, and then pressed into fine soil layer by layer, and the root neck should be flat on the ground. Immediately after planting, pour enough root water and cover the tree plate with plastic film.

Can pineapple trees be planted in the north?

Pineapple trees cannot be planted in the north, mainly because of temperature. Jackfruit is a tropical fruit tree. It can blossom and bear fruit normally in the areas where the annual average temperature is ≥ 22 ℃, the coldest monthly average temperature ≥ 13 ℃ and the absolute lowest temperature > 0 ℃. Produced in the West Gaozhi Mountains of India. It is often cultivated in Guangdong, Hainan, Guangxi, Fujian and Yunnan (southern) of China. It is also cultivated in Nepal, Sikkim, India, Bhutan and Malaysia. I like tropical climate. It is suitable for growing in frost-free areas with abundant annual rainfall. Like light, grow rapidly, bear shade slightly when young, like deep and fertile soil, avoid stagnant water.

Planting conditions of jackfruit

Jackfruit likes the hot and humid lowland environment and the warm and humid tropical climate. It is not resistant to cold, so it is required that the annual average temperature of the planting site is more than 21 ℃, the coldest monthly average temperature is more than 13 ℃, the absolute minimum temperature is more than 0 ℃, and the surface temperature is 0 ℃. Soil requirements are not strict, in the deep soil layer, fertile loose, well-drained acid soil, slightly alkaline clay or sandy loam soil, can grow normally. It is best cultivated in low hills or flat lands below 600 meters above sea level.

How to fertilize the pineapple tree

The main results are as follows: 1. young trees: the root distribution of young trees is shallow and narrow, so it is suitable to apply thin fertilizer frequently, and it is better to apply it in the way of water and fertilizer. Generally speaking, one shoot fertilizer and two fertilizers are more reasonable, that is, promoting shoot fertilizer and strong shoot fertilizer. Between before shoot sprouting and a small amount of shoot sprouting, urea was applied 20 grams per time to promote shoot in the first year. Compound fertilizer and potash fertilizer were applied to strengthen the shoots when most of the shoots were 6 cm long and the new leaves at the base of the shoots changed from light green to dark green. In the first year, the plant was applied (20 g of compound fertilizer + 15 g of potassium sulfate), and then increased year by year.

2. Fruiting trees: fruiting trees are usually fertilized 3 times a year. Flower-promoting fertilizer was applied before heading, mainly compound fertilizer, with 1 kg of compound fertilizer, 0.5 kg of potassium sulfate and 5 kg of dung water per plant. Strong fruit fertilizer is applied in the young fruit stage, mainly nitrogen and potassium, in order to promote the rapid expansion of fruit, 5 kg of pig manure water, 0.5 kg of urea, 0.5 kg of compound fertilizer and 0.5 kg of potassium sulfate per plant. The postharvest fertilizer was carried out in October with renewal and pruning, and organic fertilizer should be re-applied to promote the germination of adventitious buds. In order to accumulate nutrients for regeneration of the crown, 15 kg of chicken manure, 0.5 kg of urea, 1 kg of compound fertilizer and 0.5 kg of superphosphate could be applied.

Although pineapple kernels can be planted, it is not easy to grow pineapple trees. Because of their unique climatic requirements, planting requires a specific environment. Maybe the environment you live in is not suitable for its growth. But pineapple kernels can be eaten as ingredients, and cooking is also a good delicacy.
