High-yield planting techniques of pineapple

Pineapple is one of the fruits in summer, which has high nutritional value and edible value, and is a kind of fruit with excellent economic benefits. Pineapple is a perennial herb with strong adaptability and strong growth. it has a profit from planting in that year and attracts a lot of people to plant it.

1. Choose a place and a garden

Pineapple is a tropical fruit, it likes warm and humid areas, in addition, it likes loose and fertile, drained and breathable slightly acidic soil, should not be planted in neutral or alkaline soil, the pH value is preferably between 4-5.5. Generally planted in the leeward to the sun, the terrain is open and flat, which can reduce wind damage, reduce soil erosion, and facilitate transportation and mechanized management. In the construction of the garden, we must open ditches, do a good drainage system, turn the soil deeply and rake fine during soil preparation. If it is a sloping land with large slopes, we must build inclined terraces to conserve soil and water.

2. Planting management

Reasonable close planting is the key point to achieve high yield of pineapple. Planting density should be determined according to pineapple varieties and planting conditions. Proper close planting can not only increase planting trees, but also improve leaf photosynthesis and promote high yield. In general, single-row planting is used in areas with large slope, with about 3000-4000 plants per mu, and the row spacing is controlled in 30*120cm. 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 must be applied before planting, the yield of the land with base fertilizer is higher than that without base fertilizer, and the planting principle of pineapple is deep ploughing and shallow planting, and the soil cover should not be too deep.

3. Planting management

Planting management mainly includes fertilizer and water management, weeding and pruning. There is a great demand for potassium during the growth of pineapple, so it is necessary to increase the application of potassium fertilizer, which is based on nitrogen fertilizer, mainly nitrogen fertilizer and potassium fertilizer in the early stage, but on the contrary in the later stage. The planted pineapple needs to weed 4-5 times a year to ensure the smooth growth of the pineapple so as to prevent weeds from grabbing nutrients. In the pineapple bud stage, in order to ensure next year's yield, part of the buds of the plant can be cut off, leaving some strong buds to avoid excessive consumption of nutrients. Prepare for next year's fruit.

4. Pest control

Diseases and insect pests are also the reasons that affect the yield of pineapple. In order to achieve high and high yield of pineapple, pest control is essential. The main diseases of pineapple are wilt and heart rot. Fusarium wilt mainly harms the leaves, making the leaves soft and sagging, and the leaves change color to red, while the heart rot mainly harms the seedlings and makes the seedlings rot and die. Both of them can be controlled by chemical control, wilt can be controlled by spraying dimethoate 500 times, heart rot can be controlled by carbendazim, and shade should be properly shielded from the sun when the sun is strong.

The above are the high-yield planting techniques of pineapple brought by the pro-agricultural network. This is the end of the introduction on the high-yield planting methods of pineapple. I hope it can help you with more agricultural knowledge. Please pay attention to the pro-agricultural network.
