1、 Scientific management to improve the disease and insect resistance of flowers

First

According to the growth characteristics of flowers, such as light loving, shade tolerant, wet loving or drought tolerant, they are classified and placed

Place light loving flowers in sunny places as far as possible; Place shade resistant flowers in the lower layer of light loving flowers or where the sun cannot directly shine; The watering interval of wet flowers should be short; The watering interval of drought resistant flowers should be long

Secondly

Watering should adhere to the "see dry see wet", that is, when it is found that the soil in the flowerpot is going to be dry, pour the water thoroughly at one time, and do not pour half of the water, that is, the soil in the flowerpot is wet above and dry below. The easiest way to check whether the soil in the flowerpot is dry is to flick the middle of the flowerpot wall with your fingers and hear a crisp sound, which can judge that the soil is lack of water

At the same time

In the growing season, properly apply some compound fertilizer or soaked sesame fertilizer and water. Prune in time to remove pest branches, overlapping branches, weak branches and over dense branches

2、 Pest control

Trapping and killing pests

Aphids, whiteflies and other interesting yellowness. Set a yellow board next to the flowers and evenly apply a layer of viscous material on the board, or use the sticky board and gently move the branches of the flowers with your hands. After being frightened, aphids and whiteflies will fly to the yellow board and be stuck to death

Artificial removal of pests

When scale insects are found in flowers, they can be removed with bamboo sticks or brushes; If there are leaf eating pests on the leaves, they can be crushed to death with tweezers; If there are whiteflies and aphids, brush them gently with a brush; When insect holes are found on the flower trunk or branches, iron wire can be used to stretch into the insect holes to kill pests or bend the tip of the iron wire into a hook shape to hook out the insect body

Washing powder to control aphids, red spiders and scale insects

uses water to dissolve washing powder into a solution of 5% concentration to spray flowers to prevent aphids and spider mites. Using 20% solution can control scale insects

Control of scale insects with vinegar

Soak the cotton ball in 50ml vinegar and gently wipe the soaked cotton ball on the stems and leaves of the affected flowers and trees with tweezers to kill the scale insects and make the leaves bright and green at the same time

Control of leaf eating pests with orange peel

immerse 50 oranges into 500 ml of water and seal them in containers for 24 hours. Remove orange peel and soak in night spray to prevent leaf eating pests. p>

Onion control aphids and red spiders

take 20 grams of onion scales into 1000 ml of water for 24 hours, soak the flowers for 24 hours, spray the flowers for three times, then prevent aphids, red spiders and so on. p>

Control of underground pests with plant ash

Immersing 300g of plant ash in 500g of water for 48 hours, filtering and watering the flowers with the soaking solution can prevent underground pests

Mosquito repellent incense kills pests

Hang a plate of mosquito repellent incense on the flower branches and light it. Cover the flowers with plastic cloth. The pests can be killed in 12 hours. But not too long, otherwise, it will affect the growth of flowers

Garlic juice prevents red spider, aphid and scale shell insect

pulverized 30 grams of garlic, extracted juice and added 500 grams of water to dilute and filtered flowers spray to prevent red spider, aphid and scale insects. p>

for controlling

water is added to 60 degree Baijiu, the ratio is 1:20, watering flowers with mixed liquid. The best time is at the beginning of April, watering every 10 days for 4 ~ 5 consecutive times

Control of scale insects, aphids and red spiders with essential balm

is used as a solution in the ratio of 1:400 and air to spray flowers. This method has the best control effect on the scale insects. If you prevent aphids and red spiders, you can spray more insects. p>

Control of aphids with Zanthoxylum bungeanum

take 20 grams of pepper, 250~300 grams of water, boil for 1 to 2 minutes, spray the flowers after cooling. p>

Control of stem borers with pure alcohol

Inject pure alcohol into the borer hole of the trunk borer to immerse the pure alcohol into the branches and kill the pests

Using vaseline to control stem borers

Apply vaseline to plug the hole, resulting in poor air circulation and suffocation of pests

3、 Disease control

Control of powdery mildew with potassium permanganate

Spray flowers with potassium permanganate solution with the concentration of 0.02 ~ 0.03%. After a few days, the diseased spots will gradually disappear and the diseased leaves will return to normal growth

Prevention and treatment of powdery mildew with vinegar

spray vinegar and water into 5% solution spray. After 2 to 3 times, Bai Fen disease can be prevented. p>

Control of powdery mildew with baking soda

sodium bicarbonate solution is weakly acidic and the pathogen is difficult to survive under weak acid environment. Therefore, 0.2% small baking soda solution is applied to spray flowers to control the disease. p>

Prevention and treatment of rotten disease with garlic juice

Scrape the rotten part of the flowers with a knife to expose the healthy tissue around the diseased part. Then, evenly smear the garlic juice on the wound, with an interval of one week, 2 ~ 3 times each time

Prevention and treatment of rot with iodine

Scrape the rotten part of the flowers to the depth of the xylem, apply iodine, and apply it again after 7 ~ 10 days to completely cure

Control of root rot with plant ash

Expose the surface soil of the flowerpot to the root, cover the root with an appropriate amount of plant ash (depending on the size of the flowerpot), and then cover it with soil. The effect of preventing and controlling root rot is very good, especially Narcissus and cactus
