What is the key to planting safflower following wood?

Life habit of 1: Acer truncatum likes light and is slightly tolerant to shade, but the leaf color tends to turn green on cloudy days. Strong adaptability and drought tolerance. Hong Jimu likes warmth and cold resistance. Strong germination, strong branching ability and pruning resistance. It is barren-tolerant, but suitable for growing in fertile, moist and slightly acidic soil.

2 planting methods

Single planting, cluster planting and group planting can be used.

Solitary planting: choose tall and plump plants to plant in important positions or focus points, such as near the entrance, courtyard or lawn, to form a landscape independently, and pay attention to the strong contrast with the surrounding landscape, in order to achieve the effect of "a little red among the evergreen trees". It can play the role of the central viewpoint of the landscape or guide the line of sight.

Cluster planting: the cluster planting of safflower and other plants in the garden green space not only enriches the landscape color, but also enlivens the garden atmosphere. If you plant green trees, it can play a icing on the cake. With safflower as the main tree species, it is planted in groups to form a scenic forest, and its unique leaf color and posture are beautiful all year round. Its beautification effect is far better than pure green scenic forest. [2]

Group planting: color blocks and patterned flower beds: the annual seedlings of Acer mono are densely planted in the green space to form color blocks, which can be matched with Ligustrum lucidum, Rhododendron roseum, Rhododendron roseum, Ulmus pumila, Buxus japonicus, etc. It can not only form color contrast through leaf color contrast, but also stagger flowering period. This kind of application should choose the red strain of Tougu.

3 reproductive model

propagation by grafting

Cutting and budding are mainly used. Grafting can be carried out in February ~1October, cutting is better in spring, and bud grafting is suitable in September ~1October. Take small and medium-sized plants of Ailanthus altissima as rootstock for multi-head grafting, strengthen the management of water, fertilizer and pruning, and make them leave the nursery within 1 year.

cutting

It can be carried out from March to September. Choose loose loess as cutting substrate, ensure that the cutting substrate is ventilated and high in air humidity, keep warm but avoid direct sunlight, and pay attention to ventilation of cutting environment. Under warm and humid conditions, the cuttings of Acer mono formed a red healing body within 20-25 days, and after 1 month, 3-9 new roots grew, with a root thickness of 0. 1cm and a length of1~ 6 cm. The propagation coefficient of cutting method is large, but its growth potential is weak and it takes a long time to leave the nursery. The seedlings grafted by many heads grow vigorously and come out of the nursery quickly, but they need more labor. Cutting the tender branches from May to August, using the semi-lignified branches of that year, cutting them into 7 ~ 10 cm long cuttings, and inserting human soil1/3; The matrix of the inserted bed can be perlite or mixed with 2 parts of river sand, 6 parts of loess or mountain mud. After transplanting, build a shed for shade, spray water in time to keep the soil moist, and take root in 30 ~ 40 days.

Sowing propagation

When sowing in spring and summer, the seed germination rate of Acer truncatum is high, and it germinates about 25 days after sowing. 1 year can grow to 6 ~ 20 cm high, and 3 ~ 6 branches germinate. The red meat quality of Acer truncatum seedlings must be carefully managed in the early stage, and can only be extensively managed after the roots are lignified and browned. Sexual reproduction is generally not used for seedling production, but for the breeding research of Acer truncatum, because Acer truncatum has a long seedling stage and slow growth, and Acer truncatum seedlings (atavism) appear. Generally, the seeds are harvested in June 5438+ 10, and planted in winter in June 5438+065438+ 10, or the seeds are sealed and stored until the following spring. After scraping the sand, the seeds were drilled in a semi-sandy seedbed, and the germination rate was low about 25 days after sowing. The height of 1 year-old seedlings can reach 6 ~ 20 cm, and 3 ~ 6 branches sprout. After 2 years, you can leave the nursery for permanent planting.
