How to raise pitcher plants

Nepenthes is also known as Gotu Kola, water jar, monkey water bottle, monkey farm, and piglet cage. It is a plant belonging to the Nepenthes family Nepenthes. It is native to the mountains and forests or small streams in tropical regions such as Southeast Asia. It likes warm and humid environments..

Life habits of Nepenthes

Nepenthes likes a warm, moist, semi-shady environment, not cold-tolerant, afraid of dryness and strong light. The optimum temperature for its growth is 25℃ to 30℃; if the temperature is lower than 15℃, the plant will stop growing;Frost damage will occur on the edges of plant leaves below 10°C. Nepenthes should be grown in acidic and low-nutrient soils, usually peat, sandstone, sphagnum, charcoal, wood chips, etc., and are often cultivated by cutting or layering, The following describes the method of cutting Nepenthes in the greenhouse.

Substrate preparation

Nepenthes likes a loose and well-permeable substrate. When cutting, peat with a fiber length of 3 cm or less and a pH of 5.5 to 6.5 can be used, and the gardening expanded perlite of 3 mm to 7 mm can be used for 3 to 1Stir the ratio evenly, and spray 50% carbendazim 1000 times liquid or 50% thiophanate methyl 1000 times liquid, mix well and store it in a closed stack for three or four hours before use.

Preparation of cuttings

When collecting scion, first immerse and disinfect the scissors for harvesting in 75% alcohol solution or 0.3% potassium permanganate solution for more than 15 minutes. Choose to grow robustly and withoutPests and diseasesFor the branches, cut a leaf with a section of stem node or apical bud as cuttings, cut 2/3 of the leaves, cut the base into a 45-degree slope, and cut 8 cm to 10 cm in the vertical direction from the top of the plant stem.Branches with two or three bud points and one or two leaves. In order to reduce water loss, 2/3 of the leaves on the branches can be cut perpendicular to the veins. Place the cut spikes neatly and place them at 3000 timesSoak in the rooting powder solution for 3 to 5 minutes.

Facility preparation

Choose an appropriate area in the greenhouse, build a small arch shed with bamboo or other flexible branches, cover it with a plastic film, and set up a shading net with a shading rate of 65% above it to place the cuttings.Before putting it out, spray disinfection with 50% carbendazim 1000 times solution or 50% thiophanate methyl 1000 times solution in the shed.

Nepenthes cutting process

When cutting, install the prepared substrate in a sterilized plug tray, smooth it, and insert the prepared branches obliquely into the substrate after installation; the branches with two or three bud points are the bottom budIt is advisable to insert the points in the matrix; finally place the cuttings in a small arch shed. Spray with 800 to 1500 times carbendazim solution to wash the leaves and disinfect and sterilize, and finally use a pH value of 5.5 to 6.5.Pure water with EC below 0.5 pours through the substrate and covers it.

Hang dry and wet thermometers at different positions in the arch shed, and make environmental observation records, keep the temperature in the arch shed between 25°C and 30°C, humidity between 80% and 95%, and light control between 6000 Lux and 8000Producers should observe at any time between lux and pay attention to ventilation and dehumidification or humidification. After one month, a small protrusion will appear at the top of the branch. As time goes by, the small protrusion will gradually expand to form new buds. Wait until twoAfter three months, the new buds will produce two or three new leaves and new roots. At this time, the humidity can be gradually reduced, the light can be strengthened, and the shade net and film can be slowly removed for routine management.
