ask:
What should I pay attention to when planting threaded iron?
First, the breeding method
1. Potted standard: Threaded iron cultivation usually uses 14 cm pots, height 35 cm, crown width about 40 cm, and the listing period is 7-8 months.
2. Preparation of the substrate: Mix the peat with 5 to 40 mm of the imported peat with good porosity, drainage and aeration. Mix the peat with water. After adding water and mixing well, hold a handful of peat in your hand and let the water seep out from the finger joints. The amount of peat used in each pot of 14 cm pots is about 400 ml, and a pack of 300 liters of imported peat can hold about 750 cups.
3, pot seedlings requirements: choose professional production of high-quality seedlings, seedling height of 11 cm, crown width of 7 ~ 8 cm, no pests, no dead leaves, yellow leaves.
4. Upper cup culture: For reused old pots, it must be soaked with potassium permanganate 1000 times for more than half an hour, then rinsed with water and dried for use. Generally, the pot is planted with a caliber of 14 cm. When planting, the substrate is placed on the bottom of the cup for about 2 cm, and then the sieve seedlings are moved into the cup. The seedlings should not be planted too deep, and the base of the plant should be suitable. The matrix is ​​moderately tight and filled to the cup for 9 minutes.
Second, the matters needing attention
1, the threaded iron is not very demanding for moisture, generally watering to see dry and wet is appropriate.
2, the fertilizer of threaded iron can be used more than 20-20-20 water soluble fertilizer, the growth is slower, the demand for fertilizer is relatively small.
3, threaded iron just 3 to 4 months before planting due to the underdeveloped root system, usually half a month to spend more than 20-20-20 water soluble fertilizer 2000 times, if the amount of fertilizer is large, it is not conducive to growth. If the amount of fertilizer is large, the new leaf will shrink and shrink.
4, 4 to 5 months after the threaded iron plant growth, the root system is more developed, generally half a month to spend more than 20-20-20 water soluble fertilizer 1000 times.
