Thorn apple (Datura stramonium) likes warm, humid and sunny environment, but is afraid of waterlogging.
Note: Thorn apple, whose scientific name is datura stramonium), is commonly known as thorn apple, jimsonweed (jimson weed), devil’s snare, or devil’s trumpet.
Thorn apple (Datura stramonium) is a beautiful but highly toxic plant, just like a snake and scorpion beauty.
Its leaves and seeds are sweet, so flower lovers must be careful when raising it.
Today, let’s learn about the cultivation method of thorn apple (Datura stramonium).
Growth habits of thorn apple (Datura stramonium):
Thorn apple (Datura stramonium) has strong adaptability.
It likes warm, humid and sunny environment, but it is afraid of waterlogging.
It has no strict requirements on soil, and can be planted in general soil, but it is better to use soil rich in humus and calcareous.
Its seeds are easy to germinate, and the suitable temperature for germination is about 15 ℃.
The germination rate is about 40%, and it takes about 60 days from emergence to flowering.
When the temperature is lower than 2 ℃, the whole plant will die.
Its annual growth period is about 200 days.
Precautions for breeding thorn apple (Datura stramonium):
1. Land selection
Select sunny, fertile and well drained land for land preparation, and plough 30 cm before winter.
Combined with tillage, 2000 kg of ring fertilizer or soil miscellaneous fertilizer shall be applied per mu, and raked and fine adjusted.
After spring, turn it again, smash the soil blocks, rake them finely, and make a 1.5m wide flat border.
2. Breeding method
It usually propagates with seeds.
In the first ten days of April, we arranged a row spacing of 60cm on the border × 50 cm, open a hole 3 cm deep and scatter the seeds.
5-6 capsules per hole, covered with 1 cm of soil, slightly pressed and moisturized.
The seed consumption per mu is about 1kg.
In case of seedling transplanting, transplanting and colonization should be carried out in late May.
3. Field management
(1) Intercropping weeding
We should cultivate and weed 2-3 times during the growing period of soil cultivation, shallow hoe the topsoil, and cultivate soil at the base of the stem to prevent the stem from falling down.
Seedling fixing is generally carried out in early June.
The seedling height is 8-10 cm, and the time is 8-10 cm.
We need to remove weak seedlings and leave 2 plants in each hole.
When the height is about 15 cm, fix the seedlings and leave four plants in each hole.
After fixing the seedlings, we should apply 2000 kg of fertilizer per mu.
Next to the plant, open a hole to apply or use 10kg urea mixed with water to irrigate people.
When it grows vigorously, we can properly apply manure water or calcium superphosphate topdressing.
4. Pest control
(1) Aphids were controlled with 40% dimethoate emulsion 2000 times.
(2) The ladybug of eggplant 28 stars damages the leaves and is easy to occur in summer.
Control method: use 800 times of 90% trichlorfon technical solution spray for control, but avoid rotation with Solanaceae crops.
(3) Black spot damages leaves.
Control methods: ① clear the garden after harvest and burn the diseased leaves.
② Before and at the beginning of the disease, we sprayed 1000 times of 50% rujunte or 500 times of 65% wettable zineb.
Once a week for 3-4 consecutive times.
Note: the whole thorn apple (Datura stramonium) is toxic, especially its fruit is the most toxic. Therefore, we must not eat it.
