Because it originated from tropical area, it likes to be warm, avoid cold and frost. When the temperature is low, it grows very slowly, and requires a sunny environment.
Most species don't require strict sunshine hours, but it takes less than 12 hours to bloom.
It is not strict to the soil, but it grows well in the fertile and loose soil.
The weight of 1000 seeds is about 139, and the seeds can be used for 3-4 years. The ripening period of the fruit is not the same, it is easy to fall off after ripening, and it should be picked with ripening.
The normal seedling can grow well by sowing and cultivating seedlings with nutrient soil.
Use the seedling tray to sow, cover the fine soil about 1.5cm after sowing, not too thin, otherwise it is easy to bring the seed coat to earth, and the seedlings will emerge 4 days after sowing.
It's easy to sprout, but it's often not neat. We should select seeds carefully so that the seedlings are neat.
Jackfruit seedlings are very afraid of drought. When the drought is a little heavy, they will die. Even if watered, it is difficult to recover. This should be paid special attention to when raising seedlings.
Because it is a straight root plant, it is best to use a plastic seedling bowl with a diameter of 8 cm to form seedlings, and only transfer seedlings once, and plant one seedling in each container. If the seedlings are big and the vines are intertwined, they should be separated as early as possible and the seedling bowl should be moved away if necessary.
Generally speaking, early planting is not recommended in areas with low night temperature. It has strong self sowing ability. If you don't care about the early or late flowering, you can also use self sowing seedlings in the second year of cultivation. However, due to the lack of seed selection and late emergence, the greening effect is worse. The growth of pineapple is large, so it should be fertilized, spread evenly and turned deep.
Dig the hole for planting, remove the plastic seedling bowl, plant the seedlings in the hole, one for each hole, cover the seedling lump with fine soil, then water and cover the hole with soil.
The plant spacing of seedling cultivation or fertile soil should be appropriately larger; the plant spacing of self sown seedlings should be appropriately smaller when they are late in emergence and later in growth. Timely watering can promote the growth of stems and leaves, but pay attention not to grow too long to delay flowering.
In the early stage, artificial auxiliary vine is introduced to the scaffold, fence, tree or other supports. In the middle and later stage, the plants have strong climbing ability, so they don't need to worry about it except for modeling, and let it climb and wind. Potted plants should be often watered and fertilized.
