1. Five steps after tulip flower withering: 1, shaping and pruning.
Tulips bloom from March to May. Whenever tulips die, they need to be treated. First, they need pruning once, and the stems and useless branches and leaves of tulips need to be cut off. This can reduce nutrient consumption, concentrate nutrients on flowering branches and leaves, promote them to bloom beautiful flowers in the next year, and improve the ornamental value of tulips.
2. Normal culture
After the tulip flower is pruned, it can be watered and fertilized normally, and it can also help the tulip flower loosen the soil and promote its better growth. It is best to put it in a well-ventilated, humid and sunny place. In rainy days, tulips should not be blown by wind or rain, otherwise it will easily cause root rot and affect the normal growth of tulips. Stop watering and fertilizing in September and put it in the shade.
3, bulb preservation
How to deal with this problem after tulip flowers wither is very important. If watering and fertilization are stopped in September, all branches and leaves will wither in June 5438+ 10. The bulbs of tulip flowers are to be dug out, so don't hurt them in the process of digging, otherwise it will have a great impact on the later culture and probably lead to the death of tulip flowers.
4, the preservation method
After digging out the light bulb, it needs to be stored. First, you need to prepare a container, sand and plastic film, put the plastic film at the bottom of the prepared container, then put the sand in, water it properly, and finally put the light bulb in, keep the humidity of the sand and put it in a cool place. You can also wrap the light bulb with newspapers and other items and store it in the refrigerator.
5. Replanting
Tulip bulbs can be taken out and replanted in new soil after being preserved for 1 1 month. It needs loose and fertile soil. Humus soil, sandy soil and nutrient soil can be mixed in the ratio of 4: 4: 2, and decomposed cow dung can be added appropriately to increase soil fertility. This mixed soil is most suitable for cultivating tulips.
Matters needing attention in treatment of tulip flowers after withering 1, fertilizer selection
Every time you fertilize tulips, you must pay attention to the fertilizer. It is best not to use urea every time, otherwise it will cause tulip flowers to wither, fall leaves and die. Generally, during the growth and flowering of tulip flowers, phosphorus and potassium fertilizer can be applied once every half month, and tulip flowers will be dormant in summer, so tulip flowers do not need fertilization.
Step 2 control the temperature
If the bulbs of tulip flowers are not preserved, there may be fewer flowers or even no flowers. A big reason is that the temperature is too high, so it needs to be treated at a low temperature below 5℃ every year, which can ensure that beautiful flowers will bloom every year, making them grow better and more ornamental.
Three, tulip flower pest control 1, virus disease
Virus disease is the most common disease of tulip flowers. Although it spreads slowly, it is extremely harmful to tulips. In the early stage of the disease, the branches and leaves of tulip flowers will be deformed and dwarfed, which will affect the overall beauty of tulip flowers, and then gradually turn yellow and wither, eventually leading to the death of tulip flowers.
Prevention and control methods: If tulip flowers are found to be infected with virus, strengthen ventilation, reduce watering, apply more fertilizer, cut off all diseased branches to prevent them from spreading to other branches and leaves, and then spray virus 1, which requires 40 grams of water and 30 kilograms of 1 kg of pure milk, and prevent and control before flowering.
2. Paederia spinosa
Paederia scandens is most likely to appear when the bulbs of tulips are preserved, and its reproductive ability is extremely fast. It lays eggs every 1 ~ 3 days, which has a great influence on bulbs. Paederia will rot the bulbs, then feed on the rotten parts, and finally cause the bulbs to die, so beautiful tulips can no longer be planted.
Prevention and control methods: Before storage, the prepared sand can be exposed to the sun, which can reduce the source of insects. Then soak bulbs 10 ~ 15 minutes with 2000 times solution of 73% propargite emulsifiable concentrate or 2000 times solution of 30% propargite wettable powder for prevention and control, and finally store in sand.
Conclusion: Through the above introduction, I believe everyone knows the five steps after tulip flower withers, as well as the precautions and pest control after tulip flower withers. I hope everyone can cope and bloom beautiful tulips in life.
