How should pineapples be managed after flowering? Please explain
After pineapple flowering, the fruit rapidly expands, so the crown buds must be removed promptly, and fertilizer management and pest and disease control must be strengthened to promote fruit expansion and prevent pest and disease damage, so as to increase yield and improve quality.
The specific management techniques are as follows:
Crown bud removal About 20 days after pineapple flowering, remove the crown bud at the top of the pineapple fruit. Simply twist it gently by hand and bend it downward. Do not damage the fruit, and do this on a cloudy day. In this way, ineffective nutrient consumption can be reduced, and nutrients can be concentrated to supply the needs of fruit growth and development, enabling the fruit to expand rapidly and fully.
Applying potassium fertilizer Pineapple is a potassium-loving fruit tree. When potassium fertilizer is supplied adequately during the fruit expansion period, not only is the fruit large, but its sugar content is also high, making it sweet with a pure fragrance, good in quality, and also resistant to storage and transport. Therefore, after pineapple flowering, apply potassium fertilizer once, applying 80-100 grams of potassium chloride or potassium sulfate per plant, broadcast after rain, or apply dissolved in water.
Pest and disease prevention After pineapple flowering, attention should be paid to controlling leaf spot, black rot, anthracnose, heart rot, scale insects, aphids, and red spiders. A mixed solution of 1000-fold Nongdile and 800-fold Thiophanate-methyl must be sprayed on the leaves once every 10-15 days, for 2-3 consecutive sprays, wetting the leaves and fruit, preferably until dripping.
Spraying foliar fertilizer In combination with pest and disease control, add 0.2% urea, 0.3% potassium dihydrogen phosphate, and 1000-fold naphthaleneacetic acid or 920 mixed solution to the pesticide solution each time and spray together. This can promote full and plump fruit expansion, golden-yellow skin and flesh, high sweetness, crisp flesh, and good quality.
