What are the varieties of pineapple? What are the problems needing attention in the prevention and control of diseases and insect pests and production?

Pineapple is a tropical fruit that we like very much. There are many varieties on the market now. Many people earn money by growing pineapples and selling them. Then, the small series of soil flow nets will take you to understand the varieties of pineapple, the prevention and control of pests and diseases, and the problems that need to be paid attention to in production ~

1. Varieties of pineapple

The most popular ornamental pineapples are mainly in the genus Guangyi (such as pink pineapple), pineapple (such as beautiful pineapple) Qingtian (most species in this genus are loved by consumers), colorful pineapple (such as colorful pineapple) nest pineapple (such as red cup pineapple), Tillandsia (such as purple pineapple) Yingge pineapple (such as red Yingge, red sword, etc.) and other species

II. Control of pineapple diseases and insect pests

1. Bromeliaceae plants have fewer pests and diseases, and they have strong resistance. locust, snail, slug, etc. can eat several to dozens of leaves every day. Snails and slugs can cause leaf rot and heart rot. However, as long as the cultivation site pays attention to protection, the harm can be avoided. Quicklime powder can also be sprinkled on the ground, and the effect is obvious.

2, other pests and mites (mainly in dry season, the environment is not ventilated easy to occur. Amidex can be used. Amiticide control), night moth (mainly damage seedlings and flowers. Spraying should be carried out at night), scale insects (occasionally harmful in summer and autumn, mainly attached to leaves, mostly on the back of leaves, can be killed quickly. and so forth).

3. Piyothora Parasitica and Fusarium are the main diseases. The symptoms of Piyothora Parasitica and Fusarium are that some leaves and heart leaves of substrate rot and smell bad smell after pulling out. Generally, the high pH value and high EC value of soil caused by fertilization lead to the decrease of plant resistance. Therefore, water quality, pH value and EC value should be monitored frequently. The control method is to infuse the heart with thiophanate-methyl or thiophanate-methyl 800~-1000 times solution, or infuse the heart with mancozeb, ethyl phosphorus aluminum and other chrysanthemum killing agents, and the effect is good.

III. Problems needing attention in pineapple production

(1)After transportation or packaging of pineapple, unpacking should be immediately supplemented with water, the practice is to inject clean water into the cup, and properly loose, otherwise easy to cause leaf water loss curl and chlorosis yellow.

(2)Check water quality regularly to ensure pH and EC values are within normal ranges.

(3)Fertilization by irrigation is safer, but it needs more labor. At the same time, fertilization should be carried out by specialized personnel with strong sense of responsibility.

(4)In summer, we must pay special attention to the light not to be too strong.

(5)Pineapple fertilization does not need to be carried out every week, the length of time interval can be determined according to specific conditions, the principle is to ensure that pineapple plants are in the best growth state.

Well, the above is the variety of pineapple brought to you by the small series of soil flow nets. I hope it helps. See you next time ~
