How to make bergamot bonsai

Bergamot is a variety of citron of the genus Citrus of Rutaceae. Flowers white, lavender outside, fragrant. The apex of the fruit is divided into fingers, yellow, with ornamental value. Bergamot likes warm conditions, requires a sunny and well-ventilated environment, and likes warm, moist and well-drained soil. The soil had better be slightly acidic, and the PH value was between 5.5 and 6.5. The production and training methods of bergamot bonsai are as follows:

First, Miaoyuan

Bergamot bonsai seedlings are mostly obtained by cutting and grafting. The cuttings are obtained from the sturdy fruit branches of 2012, each section of which is 10ml / m in length. Before cutting, the base should be soaked in naphthalene acetic acid (NAA) solution with 200PPM concentration for about 10 hours. The cutting time should be at the end of April. It can take root about 1 month after insertion. Citron and citrus are often used as rootstocks for grafting propagation.

Second, modeling

1. Upper basin

Choose the time in early spring or late autumn, basin soil with fertile, moist, well-drained sandy loam, and adjust the PH value to make it slightly acidic.

2. The plastic technique of bergamot bonsai.

Including picking flowers, wiping buds, picking hearts and pruning, etc. Picking flowers, is to pick dense flowers, sterile flowers and underdeveloped flowers, leaving only the top fully developed 2murmuri 3 flowers. The aim is to concentrate nutrients and improve fruit setting rate. The sprouting power of bergamot is strong, and the new buds and shoots should be shaped by heart-picking and pruning. The principle is to leave no new shoots, less summer shoots and more autumn shoots. Because the fertilizer, water and light conditions of autumn shoots are better than those of spring shoots and summer shoots, and the branches are stronger, which is beneficial to blossom and bear fruit. In addition, attention should be paid to removing excess branches, growing branches, overdense branches and branches of diseases and insect pests.

3. Maintenance

(1) place

Bergamot likes light, warm and humid, so it should be placed in places with sufficient light and slightly higher air humidity, and pay attention to cold prevention in winter.

(2) watering

Bergamot likes to be wet, but is afraid of stagnant water. If the soil is too wet or there is stagnant water at the bottom of the basin, it will cause falling flowers and fruits. However, if the potted soil is too dry, it is also easy to cause falling flowers and fruits. Therefore, watering should be based on the principle of no dry and no watering, and watering should be thoroughly watered. Bergamot requires high air humidity, 70% Murray 90%. Therefore, in summer, we should often spray water to the leaf surface or the ground to maintain a certain degree of humidity.

(3) bergamot is evergreen all the year round, and the fruit is larger, so it needs a lot of fertilizer. In general, base fertilizer is applied once in early spring and thin fertilizer is applied every 10 days in the growing season. The amount of phosphate fertilizer should be increased appropriately at flowering stage. Before the beginning of winter, apply another thick fertilizer and water once to ensure the safety of the winter.

(4) Disease and pest control

The main diseases and insect pests of bergamot are aphids, which should be controlled timely and effectively.
