Embodiment 1

[0024] Embodiment 1: Lactobacillus plantarum (Lactobacillus plantarum P-8) and Lactobacillus casei (Lactobacillus casei) Zhang improve the test of peanut seedling growth, regularity and uniformity in saline-alkali land

[0025] Experimental location: Maotuo Village, Tingluo Town, Lijin County, Dongying City - moderate saline-alkali land (Lactobacillus plantarum group, Lactobacillus casei group, compound bacteria group and blank control group each 1 mu)

[0026] Planting management: deep plowing of the plot before sowing, combined with plowing, apply 200-300 catties of urea, 300-400 kg of diammonium phosphate, and 100-150 catties of potassium sulfate per hectare for ridging and suppression, and sow 10,000-11,000 per hectare Holes, 2 plants per hole, covered with plastic film after sowing. Fertilizer and irrigation will not be carried out later.

[0027] Experiment time: 2016.06.2-2016.8.4

[0028] Experimental crop: peanut

[0029] Dosage and method: After the peanut sowing, ...

Embodiment 2

[0035] Embodiment 2: Plant Lactobacillus (Lactobacillus plantarum P-8) and casei Lactobacillus (Lactobacillus casei) Zhang are on cotton germination rate, seedling length and root length impact test under salinity stress

[0036] Experiment location: Agronomy Laboratory of Qingdao Agricultural University

[0037] Experimental settings: Our previous research found that the basic ions of the surface soil in the coastal saline-alkali area of ​​the Yellow Delta are mainly: Na + 、HCO 3- , Cl - , SO 3 2- , in order to simulate the composition of the natural saline soil in the coastal area, we used three mixed salts of sodium chloride, sodium sulfate and sodium bicarbonate in equal proportions (1:1:1) to mix into the foundation soil after natural air-drying and sieving to remove impurities. According to the soil salinization grading standard, configure 4 salt gradients as follows: regular (0.6g / kg), light salt (1.1g / kg), medium salt (2.9g / kg), heavy salt (5.1g / kg).

Abstract

The invention discloses a compound lactobacillus preparation for improving coastal saline soil and application of the compound lactobacillus preparation. The preparation consists of lactobacillus plantarum P-8 and lactobacillus casei Zhang. Both the lactobacillus plantarum P-8 and the lactobacillus casei Zhang have an obvious effect on the growth and the metabolism of plants on saline soil and can improve the germination rate, the evenness, the uniformity and the growth ability of the plants under the coordination.

Description

technical field [0001] The invention relates to a microbial bacterial preparation, in particular to a compound lactic acid bacteria preparation capable of improving coastal saline-alkali soil and significantly improving plant resistance to saline-alkali stress, and belongs to the technical field of microorganisms. Background technique [0002] The Yellow River Delta is the coastal ecosystem with the fastest land-making speed in my country and even in the world. Since its diversion in 1855, the newly-added land area has exceeded 6,000 square kilometers. The new land has provided a vast reserve of arable land resources, and it is important to ensure the safety of my country's land resources and ecosystem services. function has a role that cannot be ignored. However, in recent years, due to the blind reclamation and utilization of human beings, the main agricultural land in the area - new silted land and improved saline-alkali cultivated land - is degrading at an alarming rate. ...
