How to breed phalaenopsis in a greenhouse, what are the requirements for building a shed, and what s

There are three points to pay attention to in the winter maintenance of phalaenopsis, one is temperature, the second is humidity, and the third is nutrients.

The cultivation and management method of phalaenopsis is mainly to control the needs of indoor temperature, humidity, light and ventilation, so as to produce potted phalaenopsis that meets the requirements of the product.

1.Temperature management: Phalaenopsis prefers warm, humid and semi-shaded environments. The optimal growth temperature is 25 to 28 during the day and 18 to 20 at night. When the temperature is above 35 in summer or below 10 in winter, phalaenopsis stops growing.

2.Water management: watering every 3 days in spring and autumn, every 2 days in summer, and 4 to 5 days in winter.

In addition, seedlings should be watered with less water and flowering plants should be watered with more water. Watering should be done in the summer after the sun goes down, and in other seasons in the morning and before the temperature rises.

3.Light management: In general, the amount of light that Phalaenopsis orchids receive is limited by how well their leaves are not burned, and the stronger the light, the better it grows.

4.Ventilation management: Generally, when the room temperature is above 28, it is necessary to try to open the window for ventilation, and if necessary, it is necessary to start the fan to exhaust the air; During the winter flowering season, ventilation should be done once a day or every other day to ensure the smooth growth of flowering plants.

5.Fertilization management: according to the different growth period of Phalaenopsis orchid, the composition of chemical fertilizer should be different, the proportion of nitrogen, phosphorus and potassium of the fertilizer is, and the vegetative growth stage of small seedlings is 20

27。Spraying the new high-lipid film once at an interval of 7 to 10 days during the growth period can prevent viral infection in the leaves, so that the branches and leaves are green and lush, and the accumulation of photosynthesis products and directional transport ability are enhanced.

6.Post-flowering treatment: After the flower withers, the flower stem can be cut off from the base, and when the substrate is aged, it should be replaced in time. Apply a callus antiseptic film to the cut to prevent nutrient loss.

Phalaenopsis grows at a temperature of 27 32 during the day and 18 25 at night in the wild, preferring high relative humidity and high shade. The ambient temperature should not be lower than 15 or higher than 32. The suitable growing temperature is 25 to 30 °C.

The temperature was maintained at 16 22 during the low-temperature flowering stage and 18 22 at the flowering stage. After 6 weeks of flowering, the temperature can increase slightly, but if the temperature is too high or the amount of light is insufficient, the peduncle will grow, the number of branches will decrease, and the number of flowers will decrease.

Illumination. Light is the key to raising Phalaenopsis orchids, and during the growth period, there should be enough light to promote the development of leaves and roots. However, too much light can also lead to leaf burning, insufficient light will cause poor plant growth, leaf distribution is sparse, peduncle underdeveloped, root development is insufficient, the best way to use shade net is double-layer movable net.

The first layer of the net is 70% shading, and the other layer of the net is 50% shading. Use the net on a sunny day or at noon to avoid extreme sunlight and avoid direct sunlight. In winter, it is generally necessary to shade 30% to 50%.
