How to grow jackfruit?

The life of jackfruit seeds is short. After the seeds are taken out from the fruit for 1 month, they cannot germinate. Therefore, the seeds should follow the harvest. Some tests showed that after 15 days of seed storage, the germination rate was 70%; after 30 days, the germination rate dropped below 40%; if soaked with gibberellin at a concentration of less than 500 mg/L for 48 hours before sowing, it could germinate 100% and seedlings grow. Ye Hao. Hainan people preserve the seeds of jackfruit by removing seeds from the fruit, washing it, drying it, mixing it with fresh husks or hibiscus, and storing it in the jars, which remains unchanged for months.

First, sowing

1. Washing: The first step in jackfruit seed processing is washing. The selected seeds should be immediately placed in clean water, and it is advisable to wash them by hand for 2 to 3 minutes. Wash it clean. Scrub two times like this and wash the pulp and sugar on the fruit. When the seeds are cleaned and sown, there will be no harm to ants and no other pests and diseases will occur.

2. Sterilization of seeds: After washing, seeds should be disinfected. Disinfectant and antiseptic drug use carbendazim 500-800 times liquid, add 15 kilograms of clear water in the prepared liquid, pour the seed into the liquid, let the seed soak for 2 to 3 minutes. The next step is to prepare for sand germination.

3, do sand bed: sand bed area can be determined according to the number of seeds. Xihe sand should be used as a bud bed. The humidity requirement is 25%. Hand sticking sticky hands, but also immediately spread out, so that the river sand can be considered qualified. First 10-15 cm thick sand as the bottom sand, must be paved, with a thin board to flatten the best. In order to facilitate management, it is generally made into a bed 10 meters long and 1 meter wide.

4. Pregermination: The bottom sand is laid, and the treated seeds are slowly laid on the sand bed. The seeds must be scattered so as not to interfere with sprouting. After the seeds have been laid, we cover the seeds with a layer of sand. The thickness is about 2 cm. Next, we have to spread a layer of stem weeds on the bud beds to achieve further shade moisturizing purposes, as well as the effect of warming.

5, sand bed management: If 18 ~ 30 °C, germination about 20 days on it. If you experience 8~18°C weather, germination will take about 35 days. To observe the dry and wet conditions of the sand bed, we must pour water in time. The frequency of watering is variable, so as to keep the soil moist. Wait until after sprouting, uncover the weeds. At this time we will see that the bud has grown to 3 to 5 centimeters.

Second, move bud

1. Seedling nursery: When the germinating seeds germinate, they are transplanted into the seedbed at a spacing of 5 cm X 10 cm. Seedlings on the seedbed are shaded with 50% shade or under shade, and the rooting water is applied after transplanting.

2. Seedlings nursery: The germs are moved into a seedling bag of 20 cm X 28 cm in size, placed in a shade net or shade of about 50%, and the rooting water is leached after transplantation.

Third, seedling management

Same as normal fruit trees. When nursery trees up to 20-25 cm can be planted.
