How to spend the winter in pineapple bonsai
The climate in the south is warm, and plants have short sleep periods and early germination. The best period of heap mining is from slight cold to severe cold. After dormancy, bromegrass accumulates a lot of nutrients, which is beneficial to germination and rooting. Roots and buds complement each other. The good development of them is the premise and key to ensure the survival of stumps and prevent them from wilting.
(2) Pre-planting treatment of Bromus
1. Clean the stack blank. After the green body is collected, according to the situation and needs of the tree body, the branches are removed, and the old knife edge left during excavation is cut off by about10 mm. After the knife edge is flattened, the trimmed green body is cleaned in water with a hard brush and dried. 2. Disinfection soaking solution: soak the cleaned tree blank in 0.3% potassium permanganate solution for about one hour, then dry it, and then soak the root of the tree blank in 0.4% tea acetic acid solution overnight to replenish the water lost during excavation and transportation and enhance the healing ability of the wound.
(3) Initial planting and management of Bromus:
To plant Bromus inermis well, we must first plant it, which refers to the period when the tree blank goes down the mountain. Generally, it has no soil, so root cells are easy to die.
In the stage of modeling and branch selection, the following points should be noted:
1. The treated tree blanks are planted in rows on the sand bed with a spacing of about 20 cm, and different sizes are interspersed among them. The planting depth is 5 ~ 10cm, depending on the size of the pile blank. Or use clay pots and wooden boxes. The principle of using a pot is "rather big than small, rather deep than shallow".
2. One month after initial planting, Bromus pratensis can generally form new roots and grow new buds. After three months, it entered a period of steady growth. In June and July of the lunar calendar, the weather is hot, plants transpiration quickly, and people with underdeveloped roots are prone to heatstroke and death. So be sure to put the stump in the shade at noon in hot summer, water it once in the morning and afternoon, and spray the whole tree with a sprayer at noon.

(4) upstream basin management
In daily management, usually full sunshine is the main thing. Note: If the temperature rises above 35℃ in the greenhouse or outdoors, it should be shaded. On the eve of rainy days, you can dig out the sand at the roots and observe the rooting situation. At this time, the roots should grow well, and the roots are many and long. If the new fibrous root of the root has reached 10 ~ 15cm, it can be potted. Don't delay, finish the potted plant a few days before the rainy season. The soil used in the upper basin should be clean and loose, preferably half mountain soil and half slag ash, which is beneficial to the survival and growth of new piles in the basin. After the pot is put on, it should be put in a greenhouse or plastic shed for four to five days. Then move outside in rainy days.
When exposed to the sun on a sunny day, the new bud has adapted to the outdoor environment and survived without hanging upside down. For the new basin piles that have adapted to the outdoor environment, under the condition of routine maintenance and depending on the production situation, an appropriate amount of thin fertilizer will be applied after one and a half months. At this time, the branches on the new pile blank are about 30 cm in length and 2 mm in thickness. Such branches are still weak, so management should be strengthened. According to the growth situation, slightly thick fertilizer water was applied every 10 day and a half until beginning of autumn, so as to be bound and shaped in early September of that year.
