How to grow pineapple

Pineapple is a tropical fruit, which is suitable for growing in a warm and humid environment, and the soil requires slightly acidic soil with fertile, loose and good air permeability. Reasonable close planting: the planting spacing on sloping land is about 30cm, the row spacing is about 120cm, and it is suitable to plant 3000-4000 plants per mu. Fertilization: nitrogen fertilizer is the main fertilizer in the early stage, potassium fertilizer is the auxiliary fertilizer, and vice versa in the later stage. Prevention and control of diseases and insect pests: mainly control heart rot and wilt, can spray carbendazim, pay attention to shading in summer.

First, choose a place to build a garden

1. Pineapple is a kind of tropical fruit, which is suitable for growing in a warm and humid environment. Pineapple should be planted in open, leeward, sunny and flat land, which is beneficial to reduce the damage of wind and reduce soil erosion. It is also convenient for later mechanized management and transportation.

2. The soil requires good drainage conditions, good air permeability, fertile and loose slightly acidic soil, the PH value should be about 4-5.5, neutral and alkaline soil is not suitable for planting pineapple, ditch should be opened after selecting the garden site, which is conducive to drainage, and then ploughing and raking, such as planting on a hillside with a large slope, in order to conserve soil and water, inclined terraces should be built.

Second, reasonable close planting

The main results are as follows: 1. Pineapple can choose the appropriate planting density according to planting conditions and varieties. Reasonable close planting of pineapple can not only increase the planting quantity, but also improve leaf photosynthesis and increase yield.

2. Single-row planting of pineapple should be adopted in the zone with large slope, the plant spacing should be about 30cm, the row spacing should be about 120cm, and the planting amount per mu should be about 3000-4000 plants. In addition, double-row value and three-row value can also be used for planting, which can be selected according to the actual situation. Sufficient base fertilizer should be applied before planting, which is beneficial to increase yield. Planting should be closely planted according to the principle of deep ploughing and shallow planting and covering shallow soil.

III. Post-management

1. The management of pineapple should be strengthened in the later stage of planting. Pineapple needs a lot of potassium during the growing period, so it should be applied mainly with an appropriate amount of nitrogen fertilizer, while in the early stage, it should be applied mainly with an appropriate amount of potassium fertilizer.

2. After the pineapple is planted, in order to make it grow normally and avoid excessive consumption of nutrients, weeds should be removed 4-5 times a year. In the pineapple bud stage, only part of the robust buds are retained, and the rest are cut off to prevent nutrient loss. This will help to ensure the yield in the coming year.

IV. Prevention and control of diseases and insect pests

1. Pineapple planting must be timely control of diseases and insect pests, so as not to affect the quality of pineapple, so as to reduce the yield.

2. The common diseases of pineapple are heart rot and wilt. Heart rot mainly harms seedlings, which can be controlled by spraying carbendazim. Under high temperature in summer, it should be shaded properly. Fusarium wilt mainly harms plant leaves and makes them change color and become soft and sagging gradually. It can be sprayed with 500-fold solution of dimethoate to prevent and cure, and avoid the sun properly under strong light.
