1. Choose a place with abundant sunshine and no accumulated water, preferably Chaoyang slope, with fertile sandy loam and good drainage. Before planting, dig deep into the ground, the planting pit should be appropriately large, and the peony root should be stretched vertically when it is placed in its hole, and it is not allowed to take root by punching holes. Don't plant too deep, it's best to just bury the roots. A pot of plants is missing.

2. Sunshine with sufficient light and temperature is beneficial to its growth, but it can't tolerate the scorching sun in summer. When the temperature is higher than 25℃, plants will be dormant. The optimum flowering temperature is 17 -20℃, but it must be treated at low temperature of 1-10℃ for 2 -3 months before flowering. The lowest temperature is -30℃, but appropriate cold-proof measures should be taken in winter in the northern cold area to avoid freezing injury. The high temperature and high humidity weather in the south is extremely unfavorable to the growth of peony. Therefore, in order to enjoy the beauty of peony flowers in the south, we must give specific environmental conditions.

3. Water and fertilize. Water twice before planting. Irrigation 1 time before winter to ensure its safe overwintering. After spring, water should be supplied according to the dry and wet conditions of the soil, but don't water it too much. Generally, fertilizer is applied three times a year, and the first time is 1 time before flowering, and quick-acting fertilizer is applied to promote flowers to bloom well. The second time is fertilization after flowering, topdressing 1 times organic liquid fertilizer. The third time is autumn and winter fertilizer, mainly base fertilizer, to promote the growth of the next spring. In addition, attention should be paid to intertillage weeding, and the soil can be loosened by shallow tillage without leaving weeds.

4. After pruning, pick flowers and prune them in time, and prune them according to the natural growth of trees and the trees you want. If you want plants to be low and have dense flowers, you should cut them short to inhibit branch expansion and tillering. Generally, it is advisable to leave 5-6 branches per plant.

5. flowering control potted peony can bloom in the spring festival by forcing flowers in winter. The method is to select peony varieties with full scales and buds (such as Zhao Fen, Luoyanghong, Shengdanlu, Gejinzi, Zhusha Lei, Dahonghu, Mokui and Wulong Peng Sheng). ) 60 days before the Spring Festival, take it out with soil to minimize damage to the roots, and dry it in the shade 12-3 days before entering the pot. When placing the flowerpot, the size of the flowerpot should match the plant to achieve a satisfactory plant type. After pouring water, it is managed normally. 50-60 days before the Spring Festival, move into a greenhouse around 10℃, and spray water 2-3 times a day to keep it moist. When the scale buds swell, gradually heat them to 25-30℃, and the temperature at night is not lower than 15℃, so that flowers can be seen in the Spring Festival.

orchid

place

The location of orchids is very important, which directly affects their growth and development. Orchids are generally placed in the open field in spring, summer and autumn (in the open shade in summer) and indoors in winter. It is best to be outdoors in an open and humid place. There should be enough light indoors, preferably facing south. In this way, it is beneficial to orchid growth. It's best to put the basin on a wooden frame or table, not on the ground.

Shading method

Orchids are mostly semi-negative plants, and most varieties are afraid of direct sunlight and need proper shade. Orchids can get more sunshine in the first half of April to promote their growth. Appropriate shade should be provided after the end of April. Erect leaf varieties from Xia Lan and Qiu Lan are best placed in the cool south to get more sunshine. Qiu Lan and Chunlan with drooping leaves should be exposed to the sun for two hours every day. Shade early every day from June to September. If a reed curtain is used, a dense curtain or two-layer thin curtain can be used. After 10, the weather turns cold and the sunshine is weak, so the shading of vegetables can be postponed, but attention should still be paid to shading around noon.

rain gear

Orchids can rain lightly, but we should avoid mildew rain, showers or even rainy days.

water

The flower proverb says that "dry orchids wet chrysanthemums" has some truth. Generally speaking, orchids are best to be eight points dry and two points wet.

Generally speaking, in June and July, when the bud length of orchid leaves is about 1.5cm, 1-2 times of dilute decomposed liquid fertilizer can be applied (chemical fertilizer is not suitable), but it is not suitable for fertilization in high temperature season. Apply 1-2 times of decomposed dilute liquid fertilizer from August to September. Orchids planted in the heart can be smeared 1-2 times with plant ash leaching solution, and the effect is very good. It is best to apply fertilizer at night and water it again the next morning.

Chunlan flowers bloom for about half a month, that is, they need to be cut; The flowers in Xia Lan should also be cut from the inflorescence one week after the last flower blooms. Precious varieties are not suitable for pollination, otherwise it will affect the next year's flowering. If it is a hybrid, it needs to be cultivated in addition to making the fruit full and mature.

Eliminate pests and diseases

It is necessary to carry out sterilization and disinfection (exposure to the hot sun is enough) to prevent diseases. Orchids are most prone to white silk disease in rainy and high temperature seasons, which can be prevented by spraying Tobuzin 800 times solution or Bordeaux solution. If the condition is serious, tobuzine can be released 500-750 times and sprayed once every 7- 10 days. Scale insects are the most common pests and attach to the base of leaves. If scale insects are found, they should be removed in time. In order to avoid the invasion of scale insects, "1059" 2000 times solution can be used for control from April.

In order to suppress the occurrence of orchid diseases, in the selection of flowerpots, besides properly controlling the degree of dryness and wetness of the soil, more pottery pots should be used, and less glaze pots should be used. In particular, orchids newly dug from poorly growing mountains must be planted in clay pots. Doing so makes the pot soil easy to dry, which can promote the growth of orchids and reduce the incidence.
