In the season of pineapple planting, you can pick the head of pineapple, root it and plant it directly in the soil. After planting pineapple, we should give pineapple enough light and water demand.
Pineapple has its own special growth habits. Most pineapples have rosette leaves. The base of the leaf cluster forms a leaf tube which can store water. The water needed for the growth and development of this pineapple is not stored in the mesophyll, but in the groove naturally formed at the central growth point of the clustered leaves (that is, the unique rosette-shaped leaf tube). In the growing season, we should often water the leaf tube to keep the soil moist and make the leaf tube have enough water to thrive. This is a special habit of pineapple.
Planting 3800 ~ 4000 pineapples per mu requires a large number of seedlings. There are three commonly used methods, including plastic germination, asexual reproduction and tissue culture.
Time and method of accelerating germination: Choose 40cm long green leaves in May ~165438+1October, accelerate germination with 250mg/L ethephon, 25ml 1% urea and 0.5% potassium chloride, and then use1200 ~ the next day after treatment.
Asexual propagation, common seedling raising, that is, using small terminal buds, small supporting buds, small sucking buds and fruit tumor buds in the field, after being cultivated in the nursery, they will enter the country by classification and go abroad. The small buds left on the fruit stalk after fruit picking are used for growth and seedling raising, and the old stems are used for cutting propagation.
Tissue culture seedlings were cultured in Ms medium at room temperature of 30℃, illumination of 65438±02h or natural illumination.
