In summer, orchids are plucked from the heart to learn five ways to blossom and blossom.

Summer, because most of the time is high temperature and high humidity state, such an environment to raise orchids, it is easy to make orchids "out of the heart", that is, orchid seedlings rotten heart. Encounter orchids were "out of the heart", how to do? In fact, orchid rotten heart focuses on prevention, mainly five strokes.

1. Rain protection

Orchid seedlings and new leaves will be acid rain, heavy rain and water damage will lead to rotten heart. After the new bud grows leaves, due to improper watering methods, it may also appear rotten heart. Therefore, we should pay attention to shelter rain, as far as possible to use the dipping pot method or watering from the side of the new seedlings to prevent water in the heart of the new seedlings.

2. Insecticides

Scale insects, red spiders, thrips, snails and other pests like to suck orchid leaves juice, bite the leaf center, the new seedling leaf center is easily infected with rot mold and lead to rotten heart. Flower friends can be used omethoate, can be killed, thiophanate, carbendazim and other pesticides, with regular preventive spraying of sterilants.

3. Thin fertilizer

Excessive use of hormones, excessive use of chemical fertilizers, raw fertilizers and other fertilizers, so that orchid growth required by the imbalance of nitrogen, phosphorus and potassium trace elements, new seedlings crazy growth, petiole soft paralysis. Light, charred leaf base; heavy, new seedlings appeared leaf center tissue necrosis, browning and blackening. Therefore, it is suggested that flower friends use orchids special organic nutrient solution, usually use, add water 500 times irrigation roots, 1000 times spray liquid, every 7-10 days once, do thin fertilizer frequently.

4. Watering

Orchid new seedling leaf heart is very tender, watering orchid water temperature and orchid leaf temperature difference is too large, easy to "scald" new seedling leaf heart, cause rotten heart. Therefore, the water used to irrigate orchids should be parked for a period of time, so that the water temperature is close to the temperature of the orchid leaves, and then put into a watering can with uniform water; in the hot season, water should be watered in the morning and evening as much as possible, and do not use tap water directly when the temperature is high in the afternoon.

5. Breathable

Hot season high temperature and humidity, poor ventilation, new seedling base airtight, easy to induce rotten heart disease. Therefore, when the orchid garden temperature exceeds 30℃, it must be shaded and cooled, keep the air circulation inside and outside the garden, and control the humidity at about 75%. Cultivated soil should be loose and breathable, and the base of new seedlings should not be buried too deep.
