1, culture method

This method is often used at present, but there are variations in later generations. The big seeds with fully developed fruits in the lower part of the trunk germinate well. Seeds are easy to lose germination ability, so they should be stored in wet sand or sown immediately after washing and drying. After storage15 days, the germination rate was 70%, and decreased to 40% after 30 days. Use 500 mg/L gibberellin before sowing. After soaking seeds for 48 hours, the germination rate of 100% can be obtained. The seedlings are growing well.

Seeds germinate by layering with wet fine sand.

2. High-pressure replication

At present, it is rarely used, and its advantages are dwarfing, easy management, early fruiting and maintaining excellent varieties;

The disadvantage is that it has no roots and is not wind-resistant.

3. Grafting propagation

Patching bud grafting is often used, and the bud grafting is selected from L (1) (2) annual cork-shaped or semi-cork-shaped branches. When using this anvil, it should be noted that the milk of pineapple affects the survival of bud grafting. You can cross-cut 1 knife above the budding position to eliminate the milk before budding. The grafting period can be carried out except in rainy and cold seasons, and the grafting position should be low.

Step 4 cut

Ring cutting and yellowing treatment were carried out 30 days before cutting, and 2000 mg/L ferulic acid +3000mg/L was used before cutting.

90% hairy roots. 1983) can be obtained by IBA rapid soaking.

In order to promote the flowering and fruiting of pineapple, farmers often smoke near the tree head to increase the content of carbon monoxide;

Concentration, increase the accumulation of photosynthetic products, or cut off the trunk with a knife to cause bleeding to achieve more flowering and fruiting.
