Problems solved by technology

At present, countries all over the world are paying close attention to the research on the application of biological nitrogen fixation technology in agricultural production. The most widely used is biological inoculation, but it is popularized because of its strains and its susceptibility to inactivation due to the influence of adverse external environments and unmatched technical measures. The application effect has not been good
It has also misunderstood more people about the research and application of biological nitrogen fixation, thinking that it is difficult, slow progress, poor effect, and difficult to achieve results, making this road tortuous

Embodiment Construction

[0006] Take the broad bean-corn wheel as an example. After the corn is harvested, the root soil of the high-yielding corn plant is dug out and reserved for later use, and some corn stalks are left to be chopped and air-dried to be used as a substrate, and then the rhizobia and bean stalks are mixed with the freshly crushed corn stalks and sprinkled on the surface, plowed and covered with a harrow flat. It is then sprinkled with broad beans and mixed with peas and raked into the soil. When harvesting broad beans and peas, first select enough nodules, and then harvest. After knocking off the seeds, store the straw in a cool place to avoid mildew. When sowing corn seeds, mix the corn root soil, corn stalks, and bean stalks with tidal water and cover them on the seeds. Then mix cowpea, kidney beans and amaranth. If it is necessary to apply chemical fertilizers and trace fertilizers, they should be composted first and then used as base fertilizers. And pay attention to reasonab...

Abstract

As disadvantages of chemical nitrogen production and a large number of used chemical fertilizers become increasingly obvious and the effect of increasing yield becomes increasingly unobvious, the invention provides a biological nitrogen production method. The core of the method is that: according to the characteristics of different nitrogen-fixing microorganisms, the relation between the different nitrogen-fixing microorganisms and plants, different living conditions of the different nitrogen-fixing microorganisms and the plants, and the mechanism principle and related scientific theories of biological nitrogen fixation, and by various measures, systematic coordination, overall cooperation and combined action, the nitrogen-fixing microorganism in soil are cultured and increased, and the nitrogen fixing capacity of the nitrogen-fixing microorganisms is improved; and the nitrogen-fixing microorganisms are used to produce nitrogenous fertilizers so as to meet the requirement of plant growth on nitrogen. The method has the advantages of capacity of continuously reducing the using amount of the chemical fertilizers, gradually recovering and improving soil fertility, improving the stress resistance and quality of crops and saving resources, environmental-friendliness, circular replaceability and sustainable development.

Description

Technical field [0001] The invention relates to a technique for cultivating soil nitrogen-fixing microorganisms, improving the nitrogen-fixing ability of the nitrogen-fixing microorganisms, and providing and meeting the high-efficiency nitrogen required by crop growth by applying comprehensive matching measures and system coordination. Its characteristics are simple and convenient, easy to grasp and easy to operate. The application of technology can continuously increase the yield of crops, and the harvested agricultural products are safe and high-quality. Background technique [0002] Chemical nitrogen production consumes a lot of energy, increases air pollution and the greenhouse effect, and uses a large amount of chemical fertilizers, which not only increases agricultural production costs, but also causes water and soil pollution, affecting human health and destroying the ecological environment. Appropriate use of chemical fertilizers can increase food production. Howev...
