Planting technique of pineapple berry

I guess a lot of people don't know what pineapple berries are. Pineapple berry is also a kind of strawberry, which is called pineapple because it tastes similar to pineapple. Pineapple berries are white with red spots and become white strawberries. The utilization value and edible value of pineapple berries are very high, and there are broad prospects for planting. Let's go with the editor to understand how pineapple berries are planted.

Planting technique of pineapple berry

Land selection and fertilization: the field of pineapple berry cultivation selects fields that have not planted strawberries for many years as Honda for the production of pineapple berries in the greenhouse, applying sufficient organic base fertilizer, about a month before planting, generally apply fully mature organic fertilizer 1500kg to 2000kg per mu as base fertilizer, and plough and rake many times.

Planting density: pineapple berries permeate around the nursery one day before digging seedlings, in order to bring good soil masses, minimize root damage, and plant in sheds according to the size of seedlings. If the seedling is raised in a nutrition bowl, the survival rate will be higher if the plastic bowl is removed when planting. The distance between the plants cultivated in the greenhouse is about 20 cm, and 1800-2000 plants are planted in each greenhouse, 6000-7000 plants per mu. The planting depth must be moderate, and the base of the new stem must be buried in the soil to facilitate the formation of new roots, but the heart of the seedling (a little part of the outer leaf stipules) can not be buried in the soil.

Temperature control: pineapple berries have different requirements for air temperature in different periods of growth and development, which should be satisfied as much as possible after warming in the greenhouse. Because the flowering and fruiting of pineberry cultivated in greenhouse is continuous and cross, it is not conducive to the flowering and fruiting of pineberry when it is kept 24: 28 ℃ in daytime and 6: 8 ℃ at night, higher than 30 ℃ or less than 5 ℃.

Humidity control: the air humidity in the greenhouse is very high, especially in the early morning to morning or cloudy and rainy weather, the relative humidity can reach 95% 100%, which hinders flowering and pollination, is easy to breed diseases, and the rotten fruit of gray mold is serious, so in addition to the ridge covering black plastic film, straw should also be laid at the bottom of the ridge to prevent water evaporation, and ventilation from the leeward to one-sided skirt should be carried out around 9: 00 on a sunny day, so that the humidity in the shed can be reduced to less than 75%.

Plant finishing: after heat preservation, the plant growth of pineapple in greenhouse is accelerated, and a large number of tillers and stolons are germinated. Timely removal can increase the leaf area of the main stem, promote the timely germination of terminal flower buds, and produce a healthy terminal inflorescence. Generally speaking, a strawberry plant retains at most 1 or 2 more robust tillers. Remove old, senile and diseased leaves in time.

Planting techniques of pineapple berries

The main results are as follows: 1. Permeable seedlings: pineapple berries permeate around the nursery one day before digging seedlings, in order to bring good soil masses, minimize root damage, and plant in greenhouses according to the size of seedlings. If the seedling is raised in a nutrition bowl, the survival rate will be higher if the plastic bowl is removed when planting.

2. Planting density: the planting distance of pineapple in greenhouse is about 20 cm, with 1800-2000 plants per greenhouse and 6000-7000 plants per mu. The planting depth must be moderate, and the base of the new stem must be buried in the soil to facilitate the formation of new roots, but the heart of the seedling (a little part of the outer leaf stipules) can not be buried in the soil.

3. Directional planting: "directional planting" is adopted to facilitate management, and it can reduce diseases and improve fruit quality. Planting 2 rows in each of the middle 5 rows, planting on both sides as far as possible (the distance between rows is controlled at about 30 cm), and make sure that the seedling arch of pineberry seedlings is planted on the back to the outside of the border. Two rows on both sides of the greenhouse are planted in a single row.

4. Post-planting management: pineapple was watered immediately after planting and survived in about 10 days, combined with weeding to loosen the soil among plants, choke roots, and often remove withered, old and diseased leaves, and do a good job of replenishing seedlings in time.

Control of pineapple diseases and insect pests

Pineapple berries will form black flowers after being damaged by low temperature. For example, the flower buds 7-8 days before flowering can be damaged by minus 20 ℃ low temperature stamens, and the pistil from 3 days before flowering to one week after flowering will also be frozen to form black flowers at minus 20 ℃ low temperature, so it is necessary to prepare the inner shed before the severe cold to strengthen the heat preservation work. The lowest temperature in the greenhouse at night was kept at 3 ℃ ~ 5 ℃, which could effectively reduce the formation of black flowers.

Matters needing attention in planting pineapple berries

Pot cultivation of pineapple berries is more common, if not a large area of planting, pot planting is quite appropriate. However, although the pond is small and easy to take care of, it is difficult to control the temperature, and the soil is less, as soon as the wind blows, the soil dries up. Pineapple berries are soils that need a certain amount of water, so the plants will dry. Therefore, it is best to use container cultivation, with ceramic basin is better, good ventilation, and easy to drain.

In the selection of soil, if it is planted in a greenhouse, you need to choose a field where strawberries have not been planted for a long time. If it is planted in a container, it is best to choose the fertile soil in the vegetable garden, organic peat soil, half of each; the density and depth of plant planting should be combed, not too deep or too shallow; in daily management, water, temperature and fertilizer should be well controlled. Many people do not apply fertilizer when growing in containers, but pineberries also grow well and can bear larger fruits. It doesn't have to be fertilized. It depends. However, it is important to check the temperature, especially after the plant blossoms, if the buds are cold, there will be black flowers.

Through the above, I believe we all know the skills of growing pineapple. Pineapple berries have high nutritional value, taste as sour and sweet as pineapple, and are deeply loved by consumers. The output of pineapple berries is rare and precious, and the planting prospect is very broad. Those who want to start a business might as well have a try!
