Second, what are the key technical points of pineapple planting management?

1. Weeding

After the temperature rises in spring, all kinds of weeds in the pineapple orchard and the withered leaves and plants after freezing in winter should be removed in time, and deeply buried or burned outside the pineapple orchard, so as to make the pineapple orchard ventilated and transparent, which is beneficial to the restoration of pineapple plant growth and eliminate the breeding places of diseases and insect pests.

2. Loosen the soil

After weeding the garden, the soil around the pineapple plant is ploughed 10-15 cm to loosen the soil, promote root activity, send early and more new roots, and grow vigorously, so as to absorb enough nutrients and water to supply the pineapple plant with rapid growth.

3. Fertilization

After loosening the soil, one fertilizer was applied in time, mainly high-quality organic fertilizer and complete nitrogen, phosphorus and potassium fertilizer, 80-100 grams of retting mature peanut cake fertilizer or tea seed cake fertilizer, 40-50 grams of nitrogen, phosphorus and potassium compound fertilizer, mixed with water or retting 8-10 kilograms of mature human and animal feces or biogas liquid. After that, fertilizer was applied every 15-20 days, mainly quick-acting nitrogen fertilizer and potassium fertilizer, 40-50 grams of urea and potassium chloride per plant, sprinkled or sprinkled with water after rain to wet all leaves evenly, so that water droplets began to flow from the growing point to the axilla of the leaves.

4. Cultivate the soil

After the first fertilization, retting rotten garbage fertilizer, pond mud, burning soil or other soil fertilizers were applied around the pineapple plant, each plant 4-5 kg, about 8-10 cm thick. The plants that have harvested winter fruit should be cultivated to the place where the new buds grow, so as to cover the exposed roots, thicken the topsoil, fertilize the soil, protect the roots and ensure the luxuriant growth of the roots.

5. Water supply

After the temperature picks up in spring, if there is sufficient water supply, the pineapple plant can grow quickly and draw leaves quickly, so it is necessary to drench in clean water every 3-5 days, about 4-6 kg per plant, or "horse race water" in the whole garden every 5-6 days to drain quickly to prevent stagnant water and make the soil moist.

6. Coverage

In spring, the pineapple border should be covered with dry straw or other weeds with a thickness of about 5-6 cm, so as to reduce water evaporation, keep the soil moist, ensure water supply, stabilize and increase soil temperature, promote new roots, and reduce weed growth. it is beneficial to the rapid growth of pineapple plants.

7. Removal of buds

After the temperature rises in spring and the pineapple plant returns to normal growth, the buds should be removed in time, and all sucking buds should be removed, only the main plant, and the plants that have already flowered and fruited should be removed, and the robust sucking buds with low position, reasonable distribution, positive bud position and no disease and insect pests should be selected as succession buds, and the rest should be removed to reduce unnecessary nutrient consumption. Concentrate nutrients to supply plant growth needs.
