Microbial agent for promoting growth of oilseed rape and oilseed rape planting method thereof

Abstract

The invention relates to the technical field of agricultural microorganisms, and particularly discloses a microbial agent for promoting growth of oilseed rape and an oilseed rape planting method thereof. The microbial agent provided by the invention comprises the following bacteria: a) at least one of corynebacterium, paracoccus, chromobacterium, achromobacter, acidithiobacillus, acidovorax, alcaligenes, arthrobacter, bacillus, cupriavidus, derxia, herbaspirillum, hydrogenobacter, hydrogenophaga, pseudomonas, pseudonocardia, rhizobium, rhodococcus, rhodopseudomonas, rhodospirillum, thiocapsa, xanthobacter, flavobacterium and wautersia; B) acetobacter, and c) azospirillum. The microbial agent provided by the invention improves the yield of oilseed rape, and is matched with a specific oilseed rape planting method to increase the yield of oilseed rape per mu, reduce the nitrogen fertilizer demand, reduce harmful germs, restore the number of microorganisms in soil and increase the diversity of the microorganisms.

Description

technical field [0001] The invention relates to the technical field of agricultural microorganisms, in particular to a microbial agent for promoting the growth of rapeseed and a method for planting rapeseed. Background technique [0002] Rapeseed, also known as oily cabbage and bitter vegetable, is collectively referred to as rapeseed in terms of agronomy for multiple species of oily seeds in plants. Rapeseed is suitable for planting on loose, fertile soil with high organic matter content and strong water and fertilizer retention. Rapeseed is mainly planted in the Yangtze River Basin, Southwest and Northwest my country. The main cultivars of rapeseed are Brassica rapa (campestris) L., Brassica juncea L. and Brassica napus L., which are important oilseeds of the Brassica genus Crop, mature rapeseed is rich in vegetable oil, which is pressed for human consumption and can provide very beneficial unsaturated fatty acids. Rapeseed oil is the most important edible oil in my cou...

AI Technical Summary

Problems solved by technology

[0003]In the traditional rapeseed management, too much labor is invested, and the labor cost is relatively high. In addition, the leaves of rapeseed are relatively large, and the use of agricultural machinery often causes damage to the leaves. The growth has a negative impact, but the management of rapeseed is relatively extensive during the planting process, the growth of rapeseed is weak, and it is difficult to resist freezing damage and drought in the later stage, resulting in low yield and quality decline; rapeseed has a large demand for nitrogen, phosphorus, and potassium in the early stage of growth. After planting rapeseed, a large amount of chemical fertilizer will be applied for nutrient supplementation, but the application of nitrogen fertilizer in the traditional planting method is unreasonable, which may easily lead to low utilization rate of nitrogen fertilizer; and the process of planting rapeseed is often accompanied by the outbreak of harmful bacteria, and more pesticides are used , it is easy to reduce the number and diversity of microorganisms in the soil
