The stem is relatively short, with many leaves, arranged in a rosette shape, and the sword is 40 to 90 cm long and 4 to 7 cm wide. Chrysanthemum fruit is fleshy, longer than 15 cm, and the flowering period is from summer to winter.
2. Growing environment
During the growing season, pineapples need to be watered frequently to keep the soil moist, and also need to be watered frequently into the leaf tube to make it have enough water, so that pineapples can thrive. Pineapple is native to tropical and hot arid areas in South America, and likes warm environment. It grows in an environment with an annual average temperature of 24 to 27 degrees Celsius, can grow in an environment of 15 to 40 degrees Celsius, and basically stops growing in an environment of 10 degrees Celsius. Although pineapple has strong drought tolerance, it still needs a certain amount of water for its growth and development. It can grow in areas with annual rainfall of 500-2800 mm. Too much rain and too high soil moisture will rot the roots. Pineapple will grow well under the condition of sufficient light, and pineapple has wide adaptability to soil, especially in loose sandy loam or mountainous red soil with rich organic matter and good drainage.
3. Cultivation techniques
Pineapple plants have strong adaptability, poor stress resistance, drought tolerance, less pests and diseases, easy cultivation and high yield. Planting density is determined according to different varieties, environmental conditions and cultivation management. In the dense planting environment, it also creates good environmental conditions for the growth and development of plants, thus forming a green microclimate environment suitable for pineapple growth. Pineapple often uses plastic hormones to accelerate germination, asexual reproduction and tissue culture. Generally, 40 cm long green leaves are selected to germinate in May-165438+1October. Vegetative propagation is a common way of raising seedlings. Small terminal buds or small supporting buds in the field are used for classified planting in the nursery. The small buds left on the fruit stalk after fruit picking are used to grow and cultivate seedlings, and the old stems are used to cut and reproduce.
Choose a place facing south, with abundant sunshine, convenient water sources and good traffic as the production base. Before planting, improve the poor soil, apply sufficient base fertilizer first, and choose strong seedlings for planting. Strengthen the management of water and fertilizer after planting. Fertilization is generally from1February to February of the following year, before germination, after fruit picking, from July to August, during which, once again, after fruit picking, base fertilizer is applied again.
