Culture methods and matters needing attention of radish and begonia

Soil: the slightly acidic soil with fertile and smooth drainage should be selected. Fertilizer: thin organic fertilizer is used during the growth period, phosphate fertilizer and potassium dihydrogen sulfate are applied during the bud period, phosphorus and potassium fertilizer is used during the growth period, and calcium superphosphate or plant ash leaching solution is used for overgrowth. Moisture: keep it moist but do not accumulate water. Temperature: suitable at about 20 ℃. Light: a lot of light is needed during the growth period. Diseases and insect pests: pay attention to the prevention and control of gray mold, soft rot, leaf spot and so on. Note: fertilizer liquid can not splash the leaves, watering does not water the bulbs.

Radish Begonia, also known as cyclamen, primroses, a crown, rabbit ear flowers, bonbonflowers, etc., is a kind of perennial herbaceous bulb flowers belonging to cyclamen of Primulaceae, it has flat round or spherical fleshy tubers, generally called bulbs, plant high 20cm-30cm, annual bulbs are light dark red, while the color of old bulbs is purple-black, and its outer part is cork. Radish and begonia blossoms luxuriantly, the flower pattern is very chic, the florescence is long, it is the outstanding one among the plants that decorate the living room, and is deeply liked by everyone.

I. Culture methods of radish and begonia

1. Soil

(1) radish and begonia prefer fertile, slightly acidic soil with smooth drainage, with a better PH value of 6-7. The cultivated soil can be planted with humus soil, forest rotten leaf soil, furnace ash, sandy vegetable garden soil, rotten compost, and mixed according to the proportion of 3ve2VOV 2V1, and appropriate amount of calcium superphosphate and other chemicals should be added to the soil.

(2) when planting, the prepared culture soil must be strictly sterilized at high temperature by the method of fumigation, and the pots should be selected according to the size of the bulbs, not for convenience. Small radish and begonia seedlings should be planted directly in larger pots.

2. Fertilizer

(1) radish begonia likes fertilizer, but does not like thick fertilizer, so it is necessary to apply fertilizer according to the principle of applying more thin fertilizer. In general, in addition to turning the basin and changing soil to apply some basic fertilizer, organic fertilizer such as rotten and thin human and animal feces and urine or fertilizer cake water should be applied every 10 days during the growth period, while quick-acting phosphate fertilizer and 0.1% potassium dihydrogen sulfate should be applied during the budding period.

(2) after the Beginning of Autumn, radish and crabapple will enter the reproductive growth period, and phosphorus and potassium fertilizer should be applied. If the plant grows excessively, it should be changed to superphosphate or plant ash extract, which can control vegetative growth, promote flower bud differentiation, and make its buds blossom.

3. Moisture

Radish and begonia can withstand drought. During the growth period, the basin soil should be kept moist, but it can not produce stagnant water. Spraying water on the leaf surface and the ground during drought and summer will help to improve air humidity and promote growth. In winter, the basin soil should be a bit dry. It can be sprayed on the leaves and the environment with clean water every other week, which can increase humidity and keep the leaves clean.

4. Temperature

The main results are as follows: (1) in winter, the suitable temperature for the growth of radish begonia is 18 ℃-20 ℃, the winter temperature should be controlled at 10 ℃-22 ℃, and the temperature should not be lower than 10 ℃. If the temperature is too low, the flower color of radish begonia will be dim and easy to wither, and if it is lower than 6 ℃, it will lead to failure of flowering.

(2) in summer: the temperature should be controlled at about 25 ℃. When the summer temperature reaches 28 ℃-30 ℃, radish and begonia will dormancy. If it is higher than 30 ℃, it will lead to leaf yellowing and flower fade. If the temperature continues to rise above 35 ℃, the tuber of radish begonia is easy to rot.

5. Lighting

Radish Begonia likes light and needs less light when it is a seedling, but it should be placed in a sunny place during the growth period and when the temperature is below 28 ℃. Shading, ventilation, water spraying and other measures should be taken properly in high temperature weather.

6. Pest control

(1) nematodes: use carbofuran and other pesticides to disinfect the basin soil. The dosage of 2g-3g in each pot is 0.1% of the soil weight, and mix well with the soil.

(2) Botrytis cinerea: timely ventilation should be carried out to reduce the humidity in the air, diseased leaves should be removed immediately, the source of infection should be reduced, and broad-spectrum fungicides such as Dysen zinc and carbendazim should be sprayed.

(3) soft rot, leaf spot, fungal atrophy and anthracnose: spray with 0.01% thiophanate solution or 0.2% thiazuron and chlorothalonil solution.

Third, points for attention of radish and begonia

The main results are as follows: 1. When applying fertilizer, we should be careful not to splash the fertilizer on the leaves, and it is not suitable to apply fertilizer in flowering, summer and winter.

2. when watering, you can not pour water on the bulb. you can pour water on the basin soil. when watering, pay attention to the water temperature and water quality. the temperature of watering should be close to the room temperature, and the water quality should use precipitated soft water.

3. When the temperature is higher than 35 ℃ and enters the dormant period, the turnip and begonia should use the sunshade net to increase the ventilation and spray water around the plant to cool down.

4. loose leaves from time to time to make the bulbs ventilated and permeable, otherwise the bulbs will be easy to mildew, remove old leaves and redundant small leaves with hands, can not use scissors, because scissors will have rust, etc., easy to cause flower stem rot.
