Embodiment Construction

[0018] 1. Preparation of two inoculations: Moses sacculus and intra-root sacculus:

[0019] 1. Use a 10-mesh soil sieve to sieve out the large particles contained in the soil, vermiculite and river sand, and then put them into a high-pressure steam sterilization pot. At 121°C for 2 hours, all the bacteria contained in the substrate will be killed. Die, and then mix the soil, vermiculite and river sand in a volume ratio of 2:3:5 to form a substrate for the propagation of arbuscular mycorrhizal fungi. At the same time, the flowerpots required for the expansion of the bacterial agents were soaked in alcohol with a volume concentration of 75% for 30 minutes, and then placed in a sterile room for 30 minutes of ultraviolet irradiation.

[0020] 2. Soak the seeds of white clover, the host of bacterial growth with 75% alcohol, for 15 minutes. After taking it out, rinse with sterile water at least 3 times to ensure that there is no alcohol residue, and then transfer it As for the acceler...

Abstract

The invention discloses a novel method for efficiently planting cold-season type grasses in early spring and relates to a method for improving the planting capability of the cold-season type grasses. According to the method, an arbuscular mycorrhizal fungi complex microbial inoculant is applied to soil, wherein the arbuscular mycorrhizal fungi complex microbial inoculant is formed by compounding glomus mosseae inoculant with glomus intraradices in the mass ratio of 1:1; the glomus mosseae inoculant and the glomus intraradices are respectively inoculant-soil mixtures obtained by micropropagation of pure spores; the inoculant-soil mixtures contain strain spores and hyphae propagules; and the quantity of the strain spores is 8-13 / g. Due to the use of the arbuscular mycorrhizal fungi complex microbial inoculant, a mycorrhiza-cold-season type grass mutual-benefit symbiont with high infection rate can be established between the cold-season type grasses and arbuscular mycorrhizal fungi and can promote the cold-season type grasses to grow more quickly and better and form more-developed root systems at the low-temperature stage in spring and the cold hardiness and physiological functions of the old-season type grasses can be remarkably improved, and thus non-point source pollution substances such as nitrogen and phosphor in the direct surface runoff in early spring are intercepted to the maximum extent and the pollution to receiving rivers is reduced.

Description

Technical field [0001] The invention relates to a method for efficient establishment of a novel cold-season grass in early spring, and relates to a method for improving the ability of cold-season grass to be established. Background technique [0002] Temperature is one of the main ecological factors affecting plant growth and distribution. The cold winter and long duration in northern China and vast mountainous areas have become an important limiting factor in the growth cycle of plants. Turfgrass vegetation in northern my country usually starts to turn green in mid-to-late April. Due to the low environmental temperature and short sunshine time, lawn vegetation grows slowly, has low activity, difficult planting, and weak watershed ecological barrier. At this time, the accumulation of snowmelt and rainfall in early spring to form surface runoff, as well as the loss of a large amount of agrochemicals caused by early spring cultivation, bring serious risks of non-point source pollu...
