Culture methods of coral beans

Soil: coral beans need to choose fertile, loose, well-drained soil. Timely watering: keep the basin soil dry and wet. Growth temperature: the suitable growth temperature is about 18-25 ℃. Reasonable lighting: shading and maintenance in spring, summer and autumn, and sufficient sunshine in winter. Rational fertilization: liquid fertilizer was applied every 15 days in the growing period, ash water was applied in the flowering stage, and phosphate fertilizer was applied in the flowering and fruit stage. Change the basin soil: change the basin in March. Control of diseases and insect pests: methyl Tobu can be used to control charcoal maggot.

I. Culture methods of coral beans

1. Growing soil: coral beans are suitable to be planted in areas with loose and fertile soil and good drainage conditions.

2. Timely watering: during the flowering period, coral beans should be properly watered, not too much, so that the soil should be a little dry and wet, which can effectively prevent flowers from falling. After setting fruit, it is necessary to control the drying and humidity to prevent fruit drop.

3. Growth temperature: coral beans are suitable for growing in a warm, sunny environment, and the suitable growth temperature is about 18-25 ℃. If the temperature is too low, they need to be covered with thin film for heat preservation to prevent the leaves from freezing damage.

4. Reasonable lighting: proper shading and maintenance should be carried out in spring, summer and autumn. When the temperature is relatively high during the day and the temperature is above 25 ℃, direct plant radiation should be avoided, otherwise it will lead to smaller leaves, shortening of branches, yellowing and even shedding of foot leaves, affecting its normal growth. In winter, because the temperature is relatively low, it can be placed in a sunny place for irradiation, which is conducive to promoting its photosynthesis, thus forming flower buds, flowering and fruit.

Matters needing attention in the culture of coral beans

1. Rational fertilization

The main results are as follows: (1) Coral beans should not be applied too much nitrogen fertilizer during the growing period, but liquid fertilizer should be applied every 15 days or so.

(2) in the flowering stage, thin plant ash water can be applied once or 0.2% potassium dihydrogen phosphate can be sprayed on the leaf surface, which is beneficial to promote leaf green fruit fertilizer, and fish meal, bone meal and other phosphate fertilizer can be applied 1-2 times during the flower and fruit period.

2. Rational watering

Coral beans need a small amount of watering in winter, generally wait for the basin soil to bleach before watering, the roots must prevent stagnant water, but also need to clean up the dust on the leaves in time.

3. Change the basin soil

The main results are as follows: (1) Coral beans can be changed in March, part of the old roots can be removed and culture soil can be added to make the new branches grow more exuberantly.

(2) Coral beans can survive the winter in the open field in Jiangsu and Zhejiang provinces. If the temperature is below minus 10 ℃, the twigs and leaves are easy to be frostbitten.

(3) Coral beans generally need to cultivate the soil in the open field to keep out the cold, and then cut off the frozen part in the next spring, and then loosen the soil and fertilize, which is beneficial to the emergence of new shoots.

4. Methods of reproduction

The main results are as follows: (1) Coral beans are generally propagated by seeds, and the ripe berries are collected in winter and spring, washed in water, and then harvested to dry and store the seeds.

(2) take out the stored seeds in spring and sow them in a shallow indoor pot. When the seedlings grow to 3-4 leaves, they can be changed into 10cm pots or transplanted in open field seedbeds.

5. prevention and control of diseases and insect pests

Potted coral beans are prone to charcoal maggot disease in high temperature and rainy season. 1 000 times of methyl Tobu can be sprayed once every 7-10 days, about 3 times continuously, and the effect is good.
