Embodiment 1

[0024] The method provided by the present invention will be described in detail below by taking the applicant's planting of perennial root flowers hibiscus sunflower and quinces as examples in the high-efficiency utilization base of coastal saline-alkali land.

[0025] The base is located in Haixing County, Hebei Province, which has a warm temperate continental monsoon climate, with an annual average temperature of 12.1°C, an average temperature of -4.6°C in January, an extreme minimum temperature of -19.9°C, and a frost-free period of 217 days. The annual sunshine hours are 2718.8 hours, and the average annual precipitation is 627.9mm, mainly concentrated in July-August, accounting for 74% of the annual precipitation. The area is a coastal plain, low-lying and flat, with an altitude of 1.3-3.6m. The soil is coastal saline soil with a salt content of more than 0.6%, which is coastal heavy saline-alkali land. The groundwater level is shallow, with an average of about 1 meter, a...

Embodiment 2

[0033] (1) Plant hibiscus sunflower and quinces chinensis according to the normal planting method without film laying or taking any measures as the blank control. Embodiment 1, comparative example 1 and blank control 2015 plant the survival rate of hibiscus sunflower and quinces, plant height and its biomass in August and other indicators are detected, and the detection method is a general method in the industry, each processing Select three plots, draw five points on each diagonal line, and take five plants at each point, measure their properties, and take the average value as the measured value. The survival rate (%) is the percentage of the number of surviving plants per unit area and the number of planted plants. The test results are shown in Table 1.

Abstract

The invention discloses a method for planting perennial flowers in heavy saline-alkali land at the seashore. The method includes the following steps that (a), a strip field or a platform field is finished in spring; (b), mulching is performed in autumn, mulch is evenly covered with a soil layer, and the mulch covered with the soil layer is perforated; (c), holes are formed in the mulch in a digging mode in spring of the next year, base fertilizer is applied to each hole before planting, roots of the perennial flowers are planted in the middles of the holes and covered with soil, the holes are treaded on, and the holes are fully irrigated with fresh water; (d), after water in the concave holes permeate into soil, the soil is covered with smashed straw; (e), weeding is needed in the growth management stage, disease and pest damage is prevented, and the flowers are gradually in bloom from June to October so that ornamental landscape can be formed. By means of the method, survival and growth of the herbaceous perennial flowers are successively achieved in heavy saline-alkali wasteland, the vegetation coverage in the heavy saline-alkali land is improved, landscape of the heavy saline-alkali land is increased, a low-cost sustainable original soil greening technology is provided for landscaping and vegetation construction in the heavy saline-alkali land at the seashore, remarkable economic, social and ecological benefits can be achieved, and application prospects are broad.

Description

technical field [0001] The invention relates to the technical field of landscape flower cultivation in saline-alkali land, in particular to a method for planting perennial flowers in coastal heavy saline-alkali land. Background technique [0002] Coastal heavily saline-alkali land is mostly a land receding from the sea, with low terrain, high groundwater table, high soil salinity, and lack of fresh water resources. Only a few halophytes can grow, the surface vegetation coverage is low, and the landscape effect is poor. At the same time, there is a large area of ​​reclamation land in the coastal area, the soil has extremely high salinity, the groundwater level is shallow, and the degree of mineralization is high. Except for some halophytes, it is difficult for general garden plants to survive. Methods such as salt have a small number of ornamental plants to survive, and there are also problems with growing difficulties. [0003] Perennial herbaceous flower plants are importa...
