Description

Technical Field

[0001] The invention relates to the technical field of nitrogen fixation and ventilation, and in particular to a soybean nodule nitrogen fixation and ventilation device and a use method thereof. Background Art

[0002] Nitrogen is an indispensable element for plant growth. Soil nitrogen fixation is of great significance for ensuring the normal growth of crops, increasing food yields, and ensuring food security. Existing soil nitrogen fixation technologies include microbial nitrogen fixation, which uses nitrogen-fixing bacteria to fix nitrogen in the atmosphere to provide an organic nitrogen source for plant growth. As a symbiotic nitrogen-fixing plant, soybeans require nearly half of their nitrogen from biological nitrogen fixation by rhizobia. As a green nitrogen fixation model, soybean biological nitrogen fixation can improve soil compaction and increase soil fertility.

[0003] The use of rhizobia in soybean production is a mature and widely used technology that can greatly improve the nitrogen fixation ability of soybeans during the growth period and supply sufficient nitrogen for soybean production. Soybean rhizobia are available in two dosage forms: liquid and solid. Solid rhizobia are applied by seed dressing or soil application. Liquid rhizobia are used by soaking seeds. Soybean rhizobia agents can also be added during seed coating, but it should be noted that the coating agent and the rhizobia agent should match each other, and the activity of rhizobia should not be inhibited by the efficacy of the seed coating agent; most of the existing studies regulate soybean root growth and nodule nitrogen fixation by indirect methods such as increasing nitrogen fertilizer, but excessive nitrogen fertilizer application not only inhibits soybean root development and nutrient absorption, but also aggravates soil compaction, especially significantly affecting soybean nodule formation and nitrogen fixation, resulting in a "nitrogen inhibition" effect. Therefore, this method not only cannot fundamentally increase the amount of nitrogen fixation in soybean nodules, but also causes unnecessary economic investment due to excessive fertilization. Therefore, it is necessary to design a soybean nodule nitrogen fixation aeration device. Summary of the invention

[0047] Working principle:

[0048] The method of use of the present invention comprises the following steps:

[0049] A. First, place the L-shaped air tube at the bottom of the soybean planting box, then cover it with planting soil, and then plant the soybeans in the planting soil;

[0050] B. When the soybeans grow to a certain stage, open the first gas flow regulating valve or the second gas flow regulating valve;

[0052] D. Nitrogen is sprayed from the nitrogen spray assembly at high pressure to the nodules of soybeans;

[0053] E. By adjusting the gas flow and observing the growth and development of soybeans.

[0054] Some microorganisms in the soil can enter the root tissue of soybeans and coexist with the roots. There are two types of this symbiosis, namely nodules and mycorrhizae. Nodules are caused by the invasion of beneficial bacteria into the root tissue, which are called rhizobia. Rhizobia reproduce in the root cortex, stimulate the division of cortical cells, and cause the root tissue to swell and protrude to form nodules. Rhizobia can convert free nitrogen in the air into nitrogen-containing compounds that can be used by plants. This is nitrogen fixation; nodules absorb the water and nutrients they need for life from the nodule cells. It can fix free nitrogen and synthesize nitrogen-containing compounds for use by leguminous plants. The symbiosis between leguminous plants and rhizobia results in high yields due to the nitrogen obtained; at the same time, due to the shedding of nodules, the root system or stumps with nodules are left in the soil, which can increase the fertility of the soil.

[0055] In summary, the present invention has novel structural design and is easy to operate. It can introduce nitrogen into soybean planting soil, promote the nitrogen fixation efficiency of soybean nodules, and thus achieve the purpose of efficient and high-quality soybean cultivation.

Moreover, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
