Pineapple planting methods and techniques have certain requirements for the environment

Selecting land for garden construction: it is not suitable to be planted in neutral or alkaline soil, and the soil needs to be turned deep and raked fine during soil preparation. Planting management: about 3000-4000 plants per mu, and each row spacing is 30x120cm. Planting management: properly increase the application of potash fertilizer, need to remove grass 4-5 times a year. Control of diseases and insect pests: Fusarium wilt can be sprayed with dimethoate 500 times, while heart rot can be controlled by carbendazim.

First, choose a place to build a garden

1. Pineapple is a kind of tropical fruit, which likes to be planted in warm, moist, loose, fertile, slightly acidic soil with good drainage and breathability. it is not suitable to be planted in neutral or alkaline soil, with a ph value of 4-5.5, usually planted in leeward and sunny landscapes, which can reduce wind damage and soil erosion.

2. It can also facilitate transportation and mechanized management, so it is necessary to open ditches during the construction of the garden, do a good drainage system, turn the soil deeply and rake the soil fine during soil preparation. If it is a hillside with a relatively large slope, it is necessary to build tilted terraces, which is conducive to soil and water conservation.

II. Planting management

The main results are as follows: 1. during the period, the planting density is determined according to the varieties and planting conditions of pineapple. Proper close planting can not only increase the planting trees, but also improve the photosynthesis of leaves and promote high yield. it is usually planted in a single row in areas with large slopes, with about 3000-4000 plants per mu.

2. The row spacing of each plant is controlled at 30x120cm, in addition to single-row planting, there are double-row planting and three-row planting, which can be selected according to local conditions. Sufficient base fertilizer is needed before planting, and the yield of the land with base fertilizer is higher than that without base fertilizer. The planting principle of pineapple is deep ploughing and shallow planting, and the soil should not be covered too deep.

III. Planting management

1. There is a large demand for potassium during the growth period of pineapple, so it is necessary to increase the application of potassium fertilizer, which is based on nitrogen fertilizer, dominated by nitrogen fertilizer in the early stage, supplemented by potassium fertilizer, and vice versa in the later stage.

2. After planting, the pineapple needs to weed 4-5 times a year, which is helpful to ensure the smooth growth of the pineapple and prevent weeds from seizing nutrients. In the pineapple bud stage, in order to ensure the yield in the coming year, part of the buds of the plant can be cut off and some strong buds can be retained to prevent excessive consumption of nutrients and prepare for the fruit of the coming year.

IV. Prevention and control of diseases and insect pests

1. The main diseases of pineapple are Fusarium wilt and heart rot. The wilt disease will harm the leaves, make the leaves soft and saggy, and the leaves turn red, while the heart rot will harm the seedlings and make them rot and die.

2. During this period, medicine can be used to control wilt, 500-fold solution of dimethoate can be sprayed to control wilt, and carbendazim can be sprayed to control heart rot. When the sun is strong, it is necessary to shade and avoid the sun.
