How do you grow pineapples?

The method of planting pineapple is to cut off the top leaves of pineapple completely and bury them in the soil to let them take root and sprout on their own, it is necessary to choose loose, fertile, draining and breathable soil, and the PH value in the soil is controlled between 4 and 5.5. deep turning and raking the soil before planting, applying bottom fertilizer can promote the growth and increase the yield of pineapple, and the work of fertilizer and water, weeding, pruning, fertilization and disease prevention can be carried out in time during planting.

Pineapple is a fruit that grows and develops in the soil. The fruit does not grow directly under the ground, but grows in the middle of the branches and leaves, exposing the ground. When planting pineapple trees, cut off the top leaves of the pineapple fruit completely and bury them in the soil, so that they can take root and sprout naturally. After a period of time, a small red leaf-shaped fruit ball will be propped out by the fruit stem. When you grow up, it will be a complete pineapple fruit.

1. Choose an orchard

Pineapple belongs to tropical fruit. To grow pineapple in warm and humid places, it is best to choose fertile and loose soil with strong drainage and air permeability. The PH value of the soil should be controlled between 4 and 5.5. The orchard should be sunny and leeward. The terrain is flat and open, so as to reduce the impact of sharpness and soil erosion on pineapple growth, and facilitate future transportation and mechanized management.

When building an orchard, we must dig trenches in the orchard for drainage, turn the soil deeply and rake fertilizer before planting pineapple. If the orchard is on a large slope, in order to conserve soil and water, tilt terraces should be built in the orchard.

2. Planting management

The planting density is determined according to different pineapple varieties and planting conditions. proper close planting can not only increase the number of seedlings, but also improve leaf photosynthesis and yield.

In the area with large slope, it is best to choose single-row planting, the planting density should be controlled at 3000-4000 plants / mu and the plant-row spacing should be controlled at about 30 × 120cm. In addition to single-row planting, double-row planting or three-row planting can also be selected according to the local situation.

Before planting, we should apply enough base fertilizer to the soil, and the yield of the land with base fertilizer is much higher than that without base fertilizer. When planting pineapple, we should follow the principle of deep ploughing and shallow planting, and the soil cover should not be too deep, so as not to affect the growth and development of pineapple.

3. Planting management

In the process of planting, the orchard should be fertilized and watered, weeded and pruned regularly. Pineapple has a large demand for potassium during the growing period, so it is necessary to apply some potassium fertilizer properly during planting, using potash fertilizer as base fertilizer, a large amount of nitrogen fertilizer in the early stage, supplemented by potassium fertilizer, and with the continuous growth of pineapple. In the later stage, it was mainly changed to potash fertilizer and supplemented by nitrogen fertilizer.

Weed the orchard 4-5 times a year to prevent weeds from seizing the nutrients of the pineapple, so as to promote the normal growth of the pineapple. In the pineapple bud stage, cut off some of the plant buds properly, leaving some buds with strong growth, so as to avoid the insufficient supply of too many buds and nutrients. Lay a good foundation for the next year's yield.

4. prevention and control of diseases and insect pests

In daily management, it is necessary to prevent pineapples from being harmed by Fusarium wilt and heart rot. If pineapples suffer from fusarium wilt, their leaves will soften and droop, and their leaves will turn red. If they suffer from heart rot, the seedlings will rot and rot and die. In the process of planting, 500 times solution of dimethoate can be sprayed to control Fusarium wilt and carbendazim to prevent heart rot.

If the sun is strong, shade the pineapple to avoid sun exposure and affect growth.
