Problems solved by technology

[0004] In recent years, my country has stepped up efforts to protect the environment, especially at the 16th National Congress of the Communist Party of China, which proposed a new road to industrialization, and put forward the idea of ​​"taking a road with high technological content, good economic benefits, low resource consumption, less environmental pollution, and less manpower. A new industrialization path that gives full play to resource advantages” is more important to the environmental protection requirements of enterprises. At present, the pollution of yeast wastewater has fundamentally restricted the development of my country’s yeast industry.

Embodiment 1

[0041] A kind of microbial fertilizer that utilizes yeast fermented liquid to prepare, described microbial fertilizer is prepared by the method comprising the following steps:

[0042] A. Activate yeast: inoculate the yeast parent species on the slant activation medium and culture it statically at 28°C for 36 hours to obtain activated yeast;

[0043] The slant activation medium is made of the following components in percentage by weight: molasses 5%, peptone 1%, yeast extract 2%, disodium hydrogen phosphate 0.3%, potassium dihydrogen phosphate 0.1%, agar 2.5%, and the balance is water, pH 7.0;

[0044] B. Cultivate seed bacteria liquid: Inoculate the activated yeast obtained in step A into the sterilized medium, which accounts for 45% of the volume of the fermentation vessel; at 28°C, the fermentation pressure is 0.025MPa, and the ventilation rate is 0.85 V / v·min, stirring speed is 10 hours under the condition of 140rpm cultivation, obtains the seed bacterial liquid;

Abstract

The invention provides a microbial fertilizer prepared from yeast fermentation broth and a preparation method of the microbial fertilizer. On the basis of the yeast fermentation broth which is rich innutrient and relatively rich in trace element, and due to adoption of a growth regulator and a slow release agent, on one hand, a fermentation product obtained through culture is particularly applicable to growth of beets, sufficient nutrients can be provided to the beets to grow, meanwhile the growth of beet earthnuts is promoted through the growth regulator, and thus the yield and the sweetnessof the beets are ensured; on the other hand, the nutrient release speed is controlled by the slow release agent, so that fertilization frequency is reduced, the effect of continuous fertilizer supplythrough one fertilization is achieved, and the working intensity of planting is alleviated.

Description

technical field [0001] The invention belongs to the technical field of microbial fertilizers, and in particular relates to a microbial fertilizer prepared from yeast fermentation liquid and a preparation method thereof. Background technique [0002] Sugar beet, also known as beetroot, is a biennial herb native to the western and southern coasts of Europe, transplanted from Sweden to Spain, and is a major source of sugar besides tropical sugarcane. Sugar beets originated on the Mediterranean coast, and the wild species of maritime beet is the ancestor of the cultivated beet. It was introduced into China from Arab countries around 1500 AD. In 1906, sugar beet was introduced to China. The cultivated species of sugar beet include sugar beet, leaf beet, root beet, and fodder beet. Among them, sugar beet is the most important commercial type. In modern times, beet sugar accounts for about 2 / 5 of the world's sugar production. Therefore, increasing the sugar content in sugar bee...
