How to grow pineapples to produce results
Today, I explain in detail how to grow pineapples to achieve results and the planting methods and requirements of pineapples and their experience in green plant maintenance. The following editor will give you a detailed answer to the scientific name of pineapples: Ananas comosus (L.) Merr.; British name: Pineapple; alias: pineapple, yellow pear, wang pear. Pineapple fruit is rich in nutrients and has excellent flavor. In addition to raw food, it can also be supplied to food processing factories to make cans, frozen pineapples, candied fruits, and salting and brewed wine vinegar. The tissue quality of pineapple leaves is of good quality and can be made into high-grade rice paper, and Bromelin can be extracted from the roots. Therefore, the leaves and roots of the pineapple garden can be used to update the residual plants. (1) Pineapple reproduces the propagule of pineapple, including seeds, crown buds, seed buds and suctioning buds. However, seeds are only used for testing and crossbreeding.
1. Only one fruit grows under normal crown buds. This seedling has the largest number of leaves among the four buds. After planting, it also has more roots. It develops vigorously and neatly, has large fruits and neat maturity. However, if it is not handled properly, it will be vulnerable to heart rot, so most fruit farmers are reluctant to use it.
2. The sprout is a propagule that grows on the fruit handle, with a dried fruit at the base. The number of buds occurring varies greatly depending on plant development, variety (line), and fruiting period. For example, the normal number of buds is 1 to 3, and the number of buds in the Mitsubishi series ranges from a few to more than 20; winter fruits and spring fruits have almost no descendants, while summer fruits have many descendants. Due to the large number of germinal buds and their resistance to transportation, they are the most commonly used propagule of pineapples.
3. Sprouts that originate from leaf axils have inconsistent development periods, so the seedling size is not uniform and the number of leaves is small. Sucking buds is indispensable for the second harvest of pineapple, so it is also called "subsequent buds" and should be reserved for the next generation of fruit in cultivation. However, when the number of suctioned buds occurs in abandoned orchards or more than 2, the one with the lower location can be retained, and the rest can be used for reproduction. However, medium seedlings must be selected to avoid early fruit bearing after planting.
4. Tuber buds are propagated from underground tubers. The leaves are slender and the smallest, and the fruits they bear are also the smallest. Generally, this seedling is not used to reproduce, so the fruits are pulled out after harvesting. However, when valuable varieties lack seedlings, it is also used for reproduction. How to grow pineapples to produce results (2) Selecting pineapples cultivated in Taiwan The Kaiying varieties are complex, with varying advantages and disadvantages. The incidence of bud mutation is quite high and there is a phenomenon of gradual degradation. Therefore, it is necessary to select seedlings of excellent strains and continue to eliminate bad systems. Maintain the purity of the variety and improve yield and quality. The characteristics of pineapple plants are greatly affected by the season and cultivation environment. Generally, summer fruits can best express the normal characteristics of pineapple varieties. Therefore, selection should be carried out in summer (summer fruits), and selection should be made from pineapple gardens where the first harvest is best. For example, an excellent Kaiying pineapple should have: large, long and simple fruits, no tumors at the base, short and thin fruit stalks, one crown bud, and 2 to 4 seed buds, which are on average attached to the fruit stalks or near the base. The buds occur early and grow fast. They have grown to the same height as the fruit before the fruit matures. The plant is low, and the leaves are green and thorny except for the tips. (3) In addition to excellent characteristics for seedling picking and planting mother plants, plants that are free of pests and diseases and are strong should also be selected. When picking fruits, use a sickle to cut off the crown buds. The wound is smooth and heals quickly. When picking sprouts, you must hold the base of the buds tightly and pick them off to prevent heart injury and causing rot. After picking seedlings, the buds should be inverted on the mother plant or on the scaffold, but they should not be piled, otherwise it may easily cause fever and rot. The appropriate density of planting should be 40,000 ~ 450,000 plants per hectare. The ridge spacing is 90 - 100 cm, the row spacing is 50 cm, and the plant spacing is 27 - 30 cm. It is best to plant in a two-row triangle.
Dense planting of pineapples can increase the yield by more than 50% compared with 250000 pineapples per hectare. It can also shade the ground, reduce the growth of weeds, maintain soil moisture, and prevent topsoil erosion. In addition, when planting closely, the plants work closely together, which can reduce lodging; retaining crown buds has a significant effect on preventing daily burning. In order for the plants to grow uniformly, seedlings must be carefully selected according to strain, bud type, quality and size, and planted in zones or ridges. The seedlings should stand upright when planting. Do not plant obliquely, otherwise the topsoil will easily rush into the heart when it rains, which will affect plant growth, and in serious cases, it will cause heart rot. Pineapples cannot be planted on rainy days or when the soil is too wet. (4) Planting method Hillsides should be planted according to contour lines, from top to bottom. Plant large seedlings above the slope and small seedlings below the slope, so that the pineapple plants can grow more orderly in the future. When planting, use planting ropes for equidistantly planting, which can make the rows neat and easy to manage. In addition, each plant occupies equal space and the plants grow uniformly.
