Description

Application of compound agent in improving pea quality and yield Technical Field The invention belongs to the technical field of modern agricultural biology, and particularly relates to application of a compound agent in improving pea quality and yield. Background Peas, which are one of the world's important edible legumes, are not only an important source of human vegetable proteins and dietary fibers, but also play a key role in sustainable agriculture due to their unique biological nitrogen fixation capabilities. The pea root can be symbiotic with rhizobium, and can convert nitrogen in the atmosphere into nitrogen which can be used by crops, thereby having important significance for reducing fertilizer application, fertility improvement and optimizing planting structure. However, current pea production is faced with serious challenges, soil acidification, frequent occurrence of soil-borne diseases, serious inhibition of pea root growth and nitrogen fixation efficiency, and reduced yield and degraded quality. In addition, extreme climates exacerbate the stress of peas, resulting in difficulty in effective relief from conventional cultivation measures. The brown algae oligosaccharide is a high-activity functional oligosaccharide composed of mannuronic acid and guluronic acid, which is obtained from marine natural brown algae by directionally degrading the brown algae through modern enzyme engineering technology. In the agricultural field, the brown alginate oligosaccharides serve as a high-efficiency biological stimulus, can excite the immune system of plants, and help crops resist drought, high temperature, saline-alkali and other adverse conditions. Meanwhile, the plant root system growth and nutrient absorption can be promoted, and the effects of improving quality and increasing yield are achieved. Nitrogen-fixing cyanobacteria, also called cyanobacteria, is a prokaryotic microorganism with unique biological functions, and is a group of nitrogen compounds in cyanobacteria, which can convert molecular nitrogen in the atmosphere into available compound nitrogen of plants through nitrogen-fixing enzymes. Nitrogen-fixing cyanobacteria, one of the oldest organisms on earth, has emerged as early as 8 hundred million years ago and is called a "natural nitrogen fertilizer plant. In agricultural production, the nitrogen-fixing blue algae not only provides nitrogen nutrition, but also can secrete active substances to promote crop growth, improve soil structure and promote straw decomposition. As an environment-friendly and sustainable green biological resource, the nitrogen-fixing blue algae has wide application prospect in the fields of biological fertilizer research and development, saline-alkali soil improvement, straw resource utilization and the like. At present, related research reports on brown algae oligosaccharide and nitrogen fixation blue algae compound agents and improving pea quality are not found in the market. Disclosure of Invention The invention aims to solve the technical problem of providing a compound agent for improving pea quality and yield and application thereof, wherein the compound agent can obviously promote pea plant growth and improve plant height, number of single plants, hundred grains, weight and actual yield. The invention solves the technical problems by adopting the technical scheme that the compound agent is applied to improving the quality and the yield of peas, and is prepared by uniformly mixing brown alginate oligosaccharide solid powder and nitrogen-fixing blue algae liquid at normal temperature, wherein the application mode of the compound agent is that the compound agent and a base fertilizer are uniformly mixed and then uniformly spread on soil. Further, the concentration of the brown algae oligosaccharide solid powder and the nitrogen-fixing blue algae liquid is 5-15 g/mL. Further, the concentration of the algae mud in the nitrogen-fixing cyanobacteria liquid is 100-200 mg/mL. Further, the mass ratio of the compound to the base fertilizer is 1:50-1:100. Further, the base fertilizer is a bio-organic fertilizer, and the application amount is 600-650 kg/mu. Compared with the prior art, the compound preparation has the advantages that the compound preparation is applied to improving the quality and the yield of peas, the compound preparation and the base fertilizer are uniformly mixed for the peas, the plant height, the number of single plants, the weight of hundred grains and the actual yield of the peas are obviously improved, the plant height of the peas is increased by 42.9%, the number of single plants is increased by 19.4%, the number of single plants is increased by 23.4%, the weight of the hundred grains is increased by 10.8%, and the actual yield is increased by 12.3%, so that the quality of the peas can be synergistically improved by applying the compound preparation provided by the invention.
