Matters needing attention in culturing Milan flowers

Fertilizer application: Milan has luxuriant branches and leaves, and new branches continue to grow during the growing period, forming spikes of flowers, so there is a need for adequate fertilizer. Lack of fertility will not only significantly reduce the number of flowers, shorten the flowering period, but also significantly lighten the color and fragrance of flowers. To this end, fertilizer should be applied in time. Topdressing with rotten cake fertilizer or sesame sauce residue is better, but Milan can not stand thick fertilizer, so fertilization should grasp the principle of applying thin fertilizer frequently, especially when topdressing in spring, avoid applying thick fertilizer. Topdressing should be applied once every 10 days, and an appropriate amount of calcium superphosphate should be added in fertilizer and water, which is beneficial to improve the quality of flowers.

Moderate watering: after watering the rice flower once in the pot, it should be watered less in half a month to promote new roots. At ordinary times, it is necessary to keep the basin soil moist and not to have too much moisture for a long time. Too dry is disadvantageous to Milan's growth, leaf wilting appears, and maintaining high air humidity is beneficial to Milan's growth. In the period of drought and vigorous growth, it is best to spray water once or twice a day.

Main points of propagation: Milan flowers are generally propagated by striping and cutting, which can be carried out during the plum rain in early spring.

The main results are as follows: 1. The high-pressure method is mostly used in South China: from late April to mid-May, strong and pest-free plants are selected, 2-year-old to 3-year-old branches are selected on the sunny side, and annular peeling is carried out at 20 cm from the bifurcation position to expose the cambium. The width of the incision is about 2 centimeters. after the incision is slightly dry for a day or two, it is wrapped with mud strips, and then wrapped with thin film to keep the mud strips moist all the time, and it will take about 50 days to take root. After the second new root was sent out, the mother plant was cut off, and the seedlings were planted in the shade with mud strips at first, and then planted in the pot more than a month later.

2. The film buckle cover moisturizing method is used in the north: 1-2-year-old branches are collected from May to July as cuttings, about 10 cm long, with 2 to 3 compound leaves, peat soil and face sand are half mixed as cutting substrate, and shading net is built on the film cover, the rooting rate can reach about 60% before and after the Beginning of Autumn. It usually takes two months to take root. Wait until the root before transplanting.

Pruning essentials: the Milan flower starts pruning and shaping from the seedlings and retains a section of the trunk 15 cm to 20 cm high. Do not let the trunk branches emerge from the soil surface, but should be bifurcated and pruned above the 15 cm high trunk to make the plant full. The lower branches of perennial plants often grow old and die. Therefore, the north should be cut every other year in high temperature season to promote the adventitious buds in the lower part of the main branch to germinate and grow new lateral branches, so as to keep the tree well-proportioned, strong, leafy and flowering.

Pot soil replacement: Milan seedlings require strong plants, intact roots, and the soil can be planted with a crown diameter of 1 × 3-1 × 2, and the depth is generally twice or equal to the diameter of the flowerpot. When adding new soil, appropriately add some phosphate fertilizer as base fertilizer, not too much. After putting on the basin, keep it in a cool place and move it to the sunny place after about a week.

Pest control:

1. Aphids spray plants with cigarette butts or pepper water. It can also be sprayed with 800 times liquid of mifepril. If the quantity is small, it can be brushed off manually with a small brush.

2. The beetle was sprayed with 1500-fold solution. When the quantity is small, it can be brushed off manually with a brush.

3. Red spiders sprayed plants with 1000 times of dichlorvos or 2000 times of dimethoate.
