Matrix preparation recipe: peat soil 90 packs (50 kg/pack), perlite 25 kg (meters watered), fine sand 2000 kg, lime powder 17.5 kg. The raw materials were all mixed well, stratified into the pool for disinfection, each layer was applied 1500 times the line grams of solution, and add 500 times the solution of dichlorvos, smoked stuffy for 10 days, out of the ground to dry for 1-2 days.
Time to prepare ramets or cuttings Time to select the seedlings or cuttings during the vigorous growth period from March to August, and use fine sand for the ramets or cuttings, and transfer them to the planting pots when the roots grow vigorously.
Planting time is selected from April to August (conditional person can also be in March) When the climate warms up, use 15-25 cm pots of different specifications (depending on the variety), put a small layer at the bottom to cut into a lot of square small floral mud, Disinfect the seedlings in the pots with a prepared disinfectant matrix and transfer them to a suitable greenhouse.
Cultivation and management of red high temperature often humid environment, not cold, afraid of drought and strong light exposure, growth should do the following.
Light to avoid direct light, especially in high temperature areas in summer, should be 70%-80% shading, flowers should be more shade, in order to facilitate beautiful flower brilliance, spring and autumn shading 30% -40%, winter full open does not shading, but It is also not possible to see direct light.
Temperature Anthurium grows well at temperatures between 20°C and 32°C, and grows most rapidly at 25°C to 28°C. It is detrimental to growth below 15°C or above 35°C and should be controlled. In the high temperature zone above 35°C in the summer, the temperature of the greenhouse film should be more than 2 meters. At the time of noon, the temperature should be sprayed and the leaf surface water should be sprayed. In the winter, if the temperature is lower than 15°C, the temperature should be increased and sufficient fertilizer should be added to promote heat preservation. In spring and autumn, when the temperature is above 22°C, the skirt film is 1m high at 8 o'clock in the morning and the film is kept warm at 5 o'clock in the evening.
Moisture should maintain adequate air humidity and soil moisture. Soilless plants mainly rely on leaf surface and aerial roots to absorb water and nutrients. Therefore, it is necessary to maintain adequate moisture, so that it can be used to water the root water and spray leaf water. Especially in the summer high temperature season, the plant water evaporates quickly. The root water must be leached once every 3 days, and the leaf surface water should be sprayed twice a day, and the cooling measures should be strengthened to keep the air humidity above 80%. Fertilizer application is the key factor in soilless cultivation of Anthurium and it can be achieved by rational fertilization in production. It is mainly based on compound fertilizer. The following fertilizer formulations can be referenced:
A large number of elements: 3 grams of potassium nitrate, 5 grams of calcium nitrate, 3 grams of magnesium sulfate, 2 grams of ammonium phosphate, 1 gram of potassium sulfate, 1 gram of potassium dihydrogen phosphate. Trace elements: disodium ethylenediaminetetraacetate 100mg, ferrous sulfate 5mg, copper sulfate 1mg, ammonium copper 2mg. Tap water: 5000ml
Be diligent and apply it sparingly and apply it with water. 3 days once root fertilizer, thin fertilizer, 15 days, once the foliar fertilizer, plant leaf foliar 668, potassium dihydrogen phosphate-based, growing about 30 leaves can spray foliar fertilizer potassium dihydrogen phosphate to promote flowering and robust More colorful.
Pests and diseases prevention and treatment of greenhouse growth Common anthracnose, leaf spot and insects such as Army worm, whiteflies, spider mites and other hazards, can be used 500 times carbendazim or cockestrol and 1,000 times more than the control of Le Si, every 15 days Spray once.
