Problems solved by technology

However, the effectiveness of mycorrhizal inoculation is mainly limited by the soil microenvironment
On the one hand, if the water and fertilizer conditions are too good, the mycorrhizal fungal infection rate will decrease, because many studies have shown that the mycorrhizal fungal infection rate is negatively correlated with the environmental water and fertilizer conditions; normal growth

Embodiment 1

[0020] A planting soil comprises a soil substrate and an ectomycorrhizal fungal fertilizer, and the volume ratio of the soil substrate to the ectomycorrhizal fungal fertilizer is 11:1. In the present embodiment, the pH of the soil substrate is adjusted to be 6.0, the organic matter content is 64.2g / kg, the total C content is 2.7%, the total N content is 0.36%, the available K content is 0.11mg / g, and the total K content is 19.2mg / g. g, the available P content is 73.2mg / kg, and the total P content is 0.47mg / g.

[0021] The ectomycorrhizal fertilizer used in this implementation is a mixture of three bacterial agents with a volume ratio of 1:1:1 of pine milk mushroom, colored bean puffball, and brown ring boletus. The preparation of ectomycorrhizal mycorrhizal fertilizer is to firstly purify and cultivate each bacterial agent separately, then subculture the purified ectomycorrhizal mycorrhizal agent for 1 to 2 generations, and then transfer it to vermiculite and peat moss with a ...

Abstract

The invention discloses planting soil for improving the photosynthesis of seedlings and application of the planting soil in the cultivation of zelkova schneideriana seedlings. The planting soil comprises a soil matrix and ectomycorrhizal bacterial fertilizer, wherein the pH and effective components of the soil matrix are specially adjusted to control the water and fertilizer conditions at an appropriate level, so that the soil matrix is matched with the ectomycorrhizal bacterial fertilizer, thereby providing the most suitable growth environment for the seedlings; the ectomycorrhizal bacterialfertilizer is prepared from lactarius deliciosus, pisolithus tinctorius and suillus luteus with a volume ratio of 1:(1-3):(1-3).According to the invention, ectomycorrhizae and plant roots form a mycorrhizal structure; the root absorption area of host plants is increased and the water and nutrient absorption of the zelkova schneideriana seedlings is improved; the photosynthesis of plant leaves canbe greatly increased; growth is promoted; the production benefit of the seedlings is enhanced; technical support and theoretical basis are provided for the cultivation and promotion of the precious species zelkova schneideriana.

Description

technical field [0001] The invention belongs to the technical field of plant ecology, and in particular relates to a planting soil for improving photosynthesis of seedlings and its application in cultivating beech seedlings. Background technique [0002] Mycorrhizal fungi (Mycorrhizal fungi) are symbionts with specific morphological structures and functions formed between soil fungi and higher plant roots. In the symbiotic system between plants and mycorrhizal fungi, plants provide carbohydrates for mycorrhizal fungi, and mycorrhizal fungi Absorbs more mineral nutrients and water for plants through its strong mycelial network. In recent years, mycorrhizal fungi have been applied to tree seedling cultivation and afforestation practices. In the process of tree introduction, the use of mycorrhizal soil to inoculate the introduced tree species can promote the growth and development of seedlings and improve the survival rate of transplanting. Ecomycorrhizae (Ecomycorrhizae) are...
