What are the prices and planting methods for four-season jackfruit saplings?

Four-season jackfruit is a new variety introduced into China from Malaysia, with the characteristics of flowering and fruiting multiple times a year, early fruiting and high yield. Grafted seedlings generally flower and bear fruit two to three years after planting. So, what is the price of four-season jackfruit saplings? How is four-season jackfruit planted?

1. What is the price of four-season jackfruit saplings?

According to prices found by the editor on major e-commerce platforms online, four-season jackfruit saplings generally cost about 10-20 yuan each, averaging about 15 yuan each, while better-quality ones cost about 25 yuan each.

2. How is four-season jackfruit planted?

1. Timely planting

Four-season jackfruit can be planted all year round, but spring planting and autumn planting are the best times. When planting, break up the soil in the planting hole finely, straighten out the seedling roots, then press in fine soil layer by layer. After planting, water thoroughly to settle the roots, and cover the tree base with plastic film to ensure the seedlings survive successfully.

2. Reasonable fertilization

Four-season jackfruit saplings should be given different fertilizers at different stages. After planting, fertilize to promote branch and shoot growth and rapid canopy formation; in addition to applying organic fertilizer as a base fertilizer in winter, apply quick-acting fertilizer before each new shoot flush to promote and strengthen the shoots; after fruit harvest, apply a heavy dose of organic fertilizer together with a small amount of quick-acting fertilizer to restore tree vigor, improve leaf function, and promote flower bud differentiation; in early spring before sprouting and flower spike emergence, apply quick-acting fertilizer to promote new shoot growth and flower spike development; when the fruit enlarges rapidly, apply fruit-strengthening fertilizer to promote fruit development.

3. Water management

Four-season jackfruit is a tropical crop, and its growth requires sufficient water, especially during the flowering period and fruit development period. If there is a long drought, small fruits drop or development stalls, the fruit is small and deformed, with small bulbs and thin flesh, and poor quality. Therefore, during the flowering and fruiting periods, water moderately according to soil dryness and moisture, and in the rainy season pay attention to drainage prevention to avoid root rot caused by rainwater accumulation.

4. Shaping and pruning

The fruiting parts of four-season jackfruit are on the trunk, main branches, and small secondary branches. When the trunk height reaches 1 m, cut back the trunk to promote branching. Cross branches, densely growing branches, and overlapping branches should be cut off as necessary. Generally, cultivate 3-4 primary branches and keep the canopy height at 3.5 m to form a reasonable tree structure. For fruiting trees, pruning is mainly done in winter.

5. Promoting flowering and fruiting

If excessive vegetative growth after planting affects flowering and fruiting of four-season jackfruit, girdling or ringing can be done on the trunk and main branches to allow more nutrients to accumulate in the aboveground branches and trunk, promoting the emergence of fruiting branches that flower and bear fruit. Alternatively, scoring wounds every 30 cm on the trunk and main branches can also achieve the effect of promoting flowering and fruiting. The principle for scoring is to pierce the cortex without injuring the xylem.

6. Pest and disease control

Among the insect pests of four-season jackfruit, longhorn beetles and beetles are common and serious, damaging branches and trunks, causing gumming, branch death, tree decline, trunk hollowing, and even rotting and death. Control methods include physically catching adults, scraping off eggs, or chemical methods such as applying a 600-fold dilution to the trunk and injecting it into insect holes. Main diseases include leaf spot, sooty mold, and soft rot of flowers and fruits, which can be controlled with 1000-fold carbendazim or 1500-fold chlorothalonil.
