Embodiment 1

[0053] In the application of mixed planting combination of flowers, the flowers that successfully establish the landscape should have high germination rate, high seedling survival rate and fast growth rate in the first year of mixed planting. There is a certain relationship between seed size and seedling vigor, and the study of seed size is helpful to analyze the seed germination and seedling survival in the early stage of establishment of open-field flower mixed-sowing combination landscape.

[0054] According to the seed size (the long axis in the three-dimensional length of the seed is taken as the seed size), it is divided into large seeds (>5.0mm), medium seeds (2.0-5.0mm), and small seeds (<2.0mm).

[0055] The average germination time is an indicator for judging the speed of seed germination and the uniformity of germination. They were classified as fast (0-2), medium (2-6), slow (>6) according to mean germination time (MGT).

[0056] The seed size and laboratory seed ...

Embodiment 2

[0063] Seedling survival rate is the ratio of the average number of seedlings 140 days after sowing to the maximum number of germinated seedlings. According to the research results, the seed size has a significant effect on the survival rate of seedlings (such as image 3 shown). The seedling survival rate of medium and large seeds was over 50%, which was significantly higher than that of small seeds (38%). Seedlings with small seeds have poor ability to resist adverse environments, resulting in a large number of seedling deaths, but their single plant seedling ability is strong, making up for quality with quantity, ensuring the continuous renewal of plants.

[0064] In addition, seed size had a significant effect on first-year seedling growth rate. The seedling growth rate of large seeds was significantly higher than that of medium and small seeds (such as Figure 4 shown). Seed size has a significant effect on plant growth in the first year of planting, with large seeds ...

Embodiment 3

[0066] Sowing density had no significant effect on seed germination rate and seedling survival rate (such as image 3 shown). This is because the germination environment and seed vigor are the key factors affecting the germination rate. Sowing density had no effect on germination rate and seedling survival rate in sufficient space. By analyzing the plant height growth rate in the seedling stage of the plant, it can be known that the sowing density has a significant impact on the growth rate of the growing seedlings in the open field environment, and the sowing density is high density (1200 grains / m 2 ) processing rate is low density (600 grains / m 2 ) 1.5 times of processing (such as image 3 shown). Interspecific competition is the same as intraspecific competition, manifested in plant morphological changes, reduced fecundity, and reduced numbers (Zhu Tingcheng, Zhong Zhangcheng, etc., 1988). The higher the seeding density, the greater the competition of the plant communi...

Abstract

The invention provides a method for constructing an open-plot flower mixed combination landscape, which includes: performing simulation sowing in a lab, dividing seeds into large-sized, medium-sized and small-sized seeds, wherein a long axis of three dimensions of each seed serves as the size of the seed, the large-sized seed is larger than 5.0mm in size, the medium-sized seed ranges from 2.0mm to 5.0mm in size, and the small-sized seed is smaller than 2.0mm in size; and then sowing the seeds on an open plot, actually sowing each type of large-sized flower seeds in the open plot by a certain amount twice to three times that of needed plants, and actually sowing each type of medium-sized or small-sized seeds by a certain amount eight times to twelve times that of the needed plants. Therefore, the amount of seedlings needed in the landscape can be guaranteed so as to ensure construction of the effective landscape according to the seed germinating amount.

Description

technical field [0001] The invention relates to the construction of a landscape, in particular to a construction method of a flower landscape. Background technique [0002] Flower mixed sowing combination landscape is a kind of flower application form that simulates nature and is full of landscape effects by artificially selecting annual, biennial and perennial flowers, and establishing through mixed sowing. [0003] Flower mixed landscapes originated in Europe in the Middle Ages, and were revitalized in England and Central Europe by William Robinson and Hermann Jager respectively at the end of the 19th century. In the 17th century, with the emergence of the concept of "enamelling mead", the landscape form of flower mixed-seeding combination landscape gradually developed. In the 19th century, it was a part of "wild gardening". meadow gardening". From the evolution of this series of nouns, it can be seen that the landscape of mixed planting of flowers has gradually matured ...
