Artificial soil and fertilizer capable of promoting nodulation of plant rhizobia

Abstract

The invention discloses an artificial soil capable of promoting nodulation of rhizobia of locust. The artificial soil comprises a mixed soil and a marine ecological fertilizer, wherein the mixed soil is composed of a raw mineral material, a vegetable fiber, a stabilizing agent, a granulating agent, an organic matter, clear water and a seed, and the marine ecological fertilizer is prepared by subjecting marine organic waste (organic refuse, sludge, etc) and marine organisms (green algae, algae, shells of crustacean, etc) to innocent treatment. According to results of experiments, when an aqueous solution prepared by dissolving an ecological fertilizer obtained in the invention in water is used to treat the root of locust, growth of rhizobia of locust is stimulated, and the amount of nodulation of the rhizobia is increased because of stimulation; and the prepared artificial soil has an excellent granule structure, can retain water, is ventilating and erosion resistant and benefits growth and propagation of the rhizobia, thereby enhancing nitrogen fixing capacity of the root of locust.

Description

technical field

[0001] The invention relates to the technical field of bioengineering, in particular to an artificial soil and fertilizer for promoting nodulation of Robinia pseudoacacia, which can be widely used in the fields of slope regreening, landscaping, ecological restoration, water and soil conservation, and the like. Background technique

[0002] Legumes—rhizobia can form root nodule symbionts, and its nitrogen fixation is more than 50% of the total biological nitrogen fixation, far higher than the sum of the world's chemical synthetic nitrogen. 75% of the nitrogen required by legumes comes from Legumes-symbiotic nitrogen fixation by rhizobia. locust( Robinia pseudoacacia L.) is not only a pioneer tree species for transforming saline-alkali land, but also a leguminous nitrogen-fixing tree species, and it has a strong ability to maintain water and soil, prevent wind and fix sand, and improve soil. The amount of nitrogen fixed by the Robinia pseudoacacia rhizobium ...

Embodiment Construction

[0031] 1. Preparation method of soil and fertilizer

[0032] The mixed soil ratio is as follows (the amount of two plastic pots):

[0033] 4.8L of clay; 12.48L of plant fiber; 80ml of stabilizer (stock solution); 3.6g of pellet agent; 128g of organic matter; 7L of water; 12.85g of seeds.

[0034] The concentration ratio of a single fertilizer aqueous solution for marine ecological fertilizers is:

[0035] ①. Chlorella polysaccharide fertilizer:

[0036] High-content bacterial powder: 1.5g, dissolved in 1L of water;

[0037] Green Enteromorpha: 1g, dissolved in 3L of water;

[0038] Enteromorpha polysaccharide: 1g, dissolved in 1.5L water;

[0039] ②. Seaweed fertilizer:

[0040] Bihuo: 1g, dissolved in 10L of water;

[0041] Amino Acid Fertilizer: The volume ratio of water to water is 1:1000.

[0042] 2. How to use the soil

[0043] Black locust seed treatment: take grading to accelerate germination. Soak the seeds in warm water (40°C~50°C) for the first time, soak fo...
