Detailed explanation of soilless cultivation techniques of ornamental pineapple

Friends who know about viewing pineapples must know that viewing pineapples only bloom once in a lifetime, but the leaves of ornamental pineapples are bright, colorful, and have a long viewing period. they are widely loved by consumers and are in great demand in the market. This paper will introduce the soilless cultivation techniques of ornamental pineapple.

1. Variety selection

The large-scale production type of soilless cultivation of ornamental pineapple is mainly propagated by tissue culture. The varieties with no disease, good plant type and good growth were selected. According to the market demand, cultivation environment, market time and other factors, determine the ordering time, buy five true leaves and neat growth of tissue culture seedlings.

2. Matrix

The root of pineapple needs a lot of air when it grows. Because the root of pineapple needs a lot of air when growing, special attention should be paid to the selection of soilless culture substrate. It is necessary to choose substrates with good permeability, water retention, drainage and chemical stability, such as coconut bran, volcanic rock, vermiculite, ceramsite, perlite, rock wool, peat soil and so on. The matrix needs to be sterilized before use.

3. Colonization

Soilless cultivation of pineapple before planting, clean the seedlings, do not touch the matrix, put it on the sterilized seedling bed, and fill the matrix to the rhizome during planting. Too deep or too shallow will affect the survival rate and growth rate of pineapple. Be careful not to get into the substrate in the leaf cup and water thoroughly after planting.

4. Change the basin

The pot needs to be changed after planting for three to four months. When changing the basin, pour water thoroughly one day in advance, pour water once after changing the basin, and can be fertilized after a month.

5. Temperature

In the seedling stage of soilless cultivation of ornamental pineapple, the temperature is generally controlled at about 20 to 30 degrees. After three months, the temperature can be appropriately reduced to 18 to 28 degrees. The temperature difference between day and night should not be too large in the early stage. The lowest temperature in winter should not be lower than 10 degrees. It is necessary to use heating equipment to heat up the greenhouse to keep the temperature above 10 degrees.

6. Humidity

Pineapples generally grow in tropical rain forests when they are of origin, and like high temperature and humidity. When soilless cultivation, the suitable air humidity is between 60% and 80, too much humidity will easily cause diseases. The humidity in the seedling stage is controlled between 70 and 80, and the loss can be controlled to 80 with the growth. During the growth process, attention should be paid to maintaining ventilation to reduce the incidence of diseases and insect pests.

Matters needing attention in culture

Watch pineapple semi-shade environment, keep warm above 12 ℃ in winter, can accept direct sunlight. Remember to expose yourself to the sun in summer! In order to prolong the flowering period, we must ensure that the maintenance conditions are optimized: adequate light, suitable water supply, warm and ventilated.

These are the soilless cultivation techniques of ornamental pineapple. Friends who want to cultivate can refer to the above points to ensure their own economic benefits.
