Detailed explanation of high-yield pineapple cultivation techniques, helping you easily increase production and income
Pineapple is one of the seasonal fruits of summer. Its nutritional value and edible value are extremely high, and it is a fruit with excellent economic benefits. Pineapple is a perennial herb with strong adaptability and vigorous growth, and it yields returns in the same year of planting, which attracts many people to grow it. Below, Qinnong Web brings you high-yield pineapple cultivation techniques.
1. Site and Orchard Selection
Pineapple is a tropical fruit, fond of warm and humid regions. In addition, it prefers loose, fertile, well-drained and air-permeable slightly acidic soil, and is not suitable for planting in neutral or alkaline soil; the pH value is best between 4 and 5.5. It is generally planted on leeward, sunny, open and flat plots, which can reduce wind damage, decrease soil erosion, and also facilitate transportation and mechanized management. When establishing the orchard, trenches must be dug and a drainage system set up well. When preparing the land, the soil should be deeply ploughed and finely harrowed. If it is a hillside with a relatively large slope, terraces with an inclination must be built to conserve soil and water.
2. Planting and Establishment Management
Reasonable close planting is the key point to achieving high pineapple yields. The planting density should be determined according to the pineapple variety and planting conditions. Proper close planting can not only increase the number of plants planted, but also improve the photosynthesis of leaves and promote high yield. Generally, single-row planting is used on plots with relatively large slopes, with about 3000-4000 plants per mu, and the plant-row spacing is controlled at 30*120cm. Besides single-row planting, there are also double-row planting and triple-row planting, which can be chosen according to local conditions. Before planting, sufficient base fertilizer must be applied. Plots with base fertilizer have higher yields than those without base fertilizer. The planting principle for pineapple is deep ploughing and shallow planting, and the soil covering should not be too deep.
3. Cultivation Management
Cultivation management mainly includes fertilizer and water management, weeding, and pruning. Pineapple has a relatively large demand for potassium during growth, so potassium fertilizer needs to be appropriately increased. When fertilizing, nitrogen fertilizer is the foundation; in the early stage, nitrogen fertilizer is dominant with potassium fertilizer as a supplement, while in the later stage it is the opposite. After planting, pineapple needs weeding 4-5 times each year to ensure smooth growth and prevent weeds from robbing nutrients. During the bud stage of pineapple, in order to ensure the yield for the coming year, part of the plant's buds can be cut off, leaving some strong buds, to avoid excessive nutrient consumption and prepare for fruiting the following year.
4. Pest and Disease Control
Pests and diseases are also reasons affecting pineapple yield. To achieve high and high-quality pineapple yields, pest and disease control is indispensable. The main pineapple diseases are wilt disease and heart rot. Wilt disease mainly damages leaves, causing leaves to soften and droop and turn red; while heart rot mainly damages seedlings, causing the seedling heart to rot and the plant to die. Both can be controlled with chemicals. Wilt disease can be controlled by spraying 500-fold dimethoate solution; heart rot can be controlled by spraying carbendazim. When sunlight is strong, appropriate shading should be provided.
