Abstract

The invention provides a bacillus amyloliquefaciens ZCM18 with broad spectrum growth-promoting and stress-resisting effects. The preservation No. of the bacillus amyloliquefaciens ZCM18 is CGMCC No.12959. The bacterial strain has higher phosphate solubilization and nitrogen fixation capability and capability of generating IAA, ACCD, siderophore and cytokinin; the tolerance of salinity can reach up to 5%; the bacillus amyloliquefaciens has higher antagonism to fusarium and rhizoctonia pathogenic bacteria and is suitable for the production of multifunctional bio-fertilizer, such as, disease prevention, growth promoting and salt and alkali resistance; the application scope is wide; the bacillus amyloliquefaciens is suitable for biological improvement of various soil (saline-alkali soil, degenerated soil and conventional cultivated land) and production of various plants (vegetables, grain crops and fruit trees); the bacillus amyloliquefaciens has obvious effects in boosting the root development, preventing and controlling root diseases, increasing the crop yield, and the like; the bacillus amyloliquefaciens is capable of reducing the dosage of chemical fertilizers and pesticides and is wide in application prospect.

Description

technical field

[0001] The invention relates to the field of soil biological improvement, in particular to a strain of Bacillus amyloliquefaciens with broad-spectrum growth-promoting and stress-resistance effects and its application. Background technique

[0002] Due to global warming, unreasonable farming (such as continuous cropping), improper use of chemical fertilizers and other factors, soil salinization, biological barriers and other problems are becoming more and more serious, which not only further deteriorates soil quality and ecological environment, but also has become an obstacle to crop production. The main factors of healthy growth and high yield and high quality. In addition, there are still large areas of land resources such as coastal beaches and inland saline-alkali land that need to be improved and utilized. At present, the main ways to solve the problem are disease-resistant breeding and chemical pesticides to control diseases, crop rotation and stubble pr...
