The latest environmental requirements for pineapple planting

Pineapple is a common tropical fruit, which originated in Brazil and was introduced into Guangdong in the 16th century. now it is widely planted in Guangdong, Fujian, Hainan, Taiwan and other places. Pineapple as a tropical fruit, can not adapt to a variety of planting environment, there are still certain requirements for planting conditions, let's take a look at the environmental requirements of pineapple planting.

1. Soil requirements

Pineapple has strong adaptability to the soil, but its root system is shallow, so the planting soil should be loose, fertile, well-drained sandy soil or mountain red soil, not clayey and poorly drained soil. It also has a strict requirement for soil, that is, acidity and alkalinity, pineapple like acidic soil, avoid neutral and alkaline soil, neutral and alkaline soil will lead to poor growth, soil pH is suitable between 4 and 5.5.

2. Temperature requirement

Since it is a tropical fruit, it likes the warm and humid zone, the suitable temperature for growth is 15-40 degrees, the temperature below 15 degrees is slow, the temperature below 10 degrees will stop growing, and the temperature below 5 degrees will cause frost damage. It is different to the temperature in each growth stage, in the bud is to keep the temperature at about 23 degrees, which is conducive to germination, but also appropriate shade, in the root growth temperature of about 30 degrees, if higher than 40 degrees or less than 5 degrees will stop growing, in winter should pay attention to heat preservation measures to avoid freezing damage.

3. Lighting requirements

Pineapple is native to tropical rain forest and can tolerate semi-shade, but it is necessary to ensure its sufficient light in artificial planting, so that it can grow well, accumulate sugar quickly, and have high yield and quality. if the light is insufficient, the growth and development will be poor. Sweetness, high acidity, poor quality. Generally, the light is reduced by 20%, and the output is reduced by 10%. Although sufficient light is needed, when the sun is hot in summer, the sun is fierce, which will cause leaves to burn and cause discoloration, and the fruit is also easy to burn, so we should pay attention to shade and sun protection.

4. Moisture requirement

Pineapple has strong drought tolerance, but it still needs a certain amount of water in the growth stage, so it is suitable to grow in the area with 500-2800mm annual precipitation, and the main planting areas in China can meet its water demand. It can adjust itself, when there is a lack of water, it will reduce the transpiration of the plant and reduce the consumption of water. When there is a serious lack of water, the leaves change from green to red and yellow, and it is necessary to water and irrigate to prevent the plant from dying. In areas with a large number of Rain Water, there is too much water in the soil, which is easy to be infected with diseases and lead to rotten roots, so it should be drained in time after heavy rain.

The above are the requirements of the pineapple planting environment brought by the pro-agricultural network. Pineapples are mainly planted in Hainan and the coastal areas of Guangdong and Fujian, where there are typhoons all the year round. Protective measures should be taken when planting to avoid excessive wind. It leads to plant blowing down, fruit stalk blowing off, leaf twisting.
