Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] Seedling transplanting can cultivate strong seedlings and save land, and choosing a suitable seedling substrate formula is the basic guarantee for cultivating strong seedlings. Peat, vermiculite, perlite and sawdust always have different disadvantages when used as a single substrate. According to different cultivation objects, using peat, vermiculite, perlite and sawdust as raw materials to design the compound matrix formula can maximize the strengths and avoid weaknesses, so that the plants can grow better. To this end, different compound substrates were designed, the substrate formulations suitable for the growth ...

Abstract

The invention belongs to the technical field of soilless cultivation, and discloses a special soilless cultivation substrate for culturing ornamental sunflower seedlings and a preparation method of the cultivation substrate. The soilless cultivation substrate of an ornamental sunflower comprises grass charcoal, vermiculite and perlite, the volume ratio of the grass charcoal, the vermiculite to theperlite is 2:1:1. Seedling growth is strong, and a seedling strength index is remarkably higher than that of seedlings treated by other substrates. Particularly, root system vigor, chlorophyll content and net photosynthetic rate of the ornamental sunflower seedlings are higher than those of seedlings treated by other substrates. The substrate is excellent in formula, physicochemical properties and nutritional components are better, plant root system growth is better, the good root systems effectively absorb moisture and nutrient, generation of substances such as chlorophyll is facilitated, sufficient moisture is supplied, and more chlorophyll is generated, so that photosynthesis of plants is stronger.

Description

technical field [0001] The invention belongs to the technical field of soilless cultivation, and in particular relates to a special soilless cultivation substrate for ornamental sunflower seedling cultivation and a preparation method thereof. Background technique [0002] Ornamental sunflower (Helichrysum bracteatum) is a plant of the genus Helichrysum in the Asteraceae family, native to North America. The flower has a beautiful meaning, easy management and maintenance, bright colors when planted in a large area, and is very ornamental. At present, it is mostly cultivated in the south and north of my country. Soilless cultivation is a modern cultivation technique. Soilless cultivation replaces the traditional soil environment with an artificial cultivation environment, which provides a better growth environment for the roots of plants with its excellent physical and chemical properties while reducing soil-borne diseases. Research on the compound substrate formula of ornam...
