Pineapple Varieties, Pest and Disease Control, and Production Notes
Pineapple is a tropical fruit that is very popular with us. There are quite a few varieties on the market now. Many people make money by growing pineapples and then selling them. So the Tuliu.com editor will now introduce you to pineapple varieties, pest and disease control, and things to note in production~
1. Pineapple Varieties
The sought-after ornamental bromeliads are mainly concentrated in the genera Aechmea (such as Aechmea fasciata, the silver vase), Ananas (such as Ananas bracteatus, the red pineapple), Guzmania (the vast majority of species in this genus are loved by consumers), Neoregelia (such as Neoregelia, the blushing bromeliad), Nidularium (such as Nidularium, the red cup bromeliad), Tillandsia (such as Tillandsia, the purple-flowered bromeliad), and Vriesea (such as Vriesea, the flaming sword and red sword), among others
2. Pest and Disease Control in Pineapple
1. Bromeliads have relatively few pests and diseases, and they have strong resistance themselves. On the pest side, there are mainly locusts, snails, slugs, and so on. A single locust can eat anywhere from several to dozens of leaves in 1 d, while damage by snails and slugs can cause leaf rot and heart rot, but as long as the cultivation site is properly protected, their damage can generally be avoided; quicklime powder can also be spread on the ground, with fairly obvious effect
2. Other pests include mites (mainly in the dry season, and prone to occur when the environment is not well ventilated; can be controlled with acaricides such as Amitraz and Propargite), noctuid moths (mainly damaging seedlings and flowers; spraying must be done at night), and scale insects (occasionally damaging in summer and autumn, mainly attached to leaves, mostly on the underside; can be controlled with Prothiofos, Dimethoate, and so on), among others.
3. Diseases mainly include heart rot (PiyothoraParasitica) and Fusarium, whose symptoms are rotting of the leaves near the substrate and the heart leaves, with a foul odor detectable after pulling them out. This is generally caused by high pH and fertilization raising the soil EC value, which lowers the plant's resistance, so water quality, pH, and EC value must be monitored regularly. The control method is to drench the heart with a 800-1000 times dilution of Thiophanate-methyl or Thiophanate, or to drench the heart with fungicides such as Mancozeb and Fosetyl-aluminium for treatment, with good results.
3. Issues to Note in Pineapple Production
(1) For pineapples that have been transported or packaged, water should be replenished immediately after unpacking. The method is to pour clean water into the cup and loosen the binding appropriately; otherwise the leaves are prone to losing water, curling, and turning yellow from loss of green.
(2) Check water quality frequently to ensure that pH and EC values are within the normal range.
(3) Drenching the heart for fertilization is relatively safe, but it requires more manual labor, and fertilization must be handled by specially assigned personnel with a strong sense of responsibility.
(4) In summer, especially, note that the light must not be too strong.
(5) Pineapples do not need to be fertilized every week; the length of the interval can be determined according to specific conditions, and the principle is to keep the pineapple plant in the best growing state.
Alright, the above is the pineapple varieties brought to you by the Tuliu.com editor. We hope it is helpful to everyone. See you next time~
