This invention provides a composite biosynergist, its preparation method, and its application. The composite biosynergist is composed of polyglutamic acid, humic acid, fucoidan oligosaccharide, and plant polyphenols. The synergistic effect of the active substances polyglutamic acid γ-PGA, humic acid HA, fucoidan oligosaccharide AOS, and plant polyphenol PP in the composite biosynergist is essentially manifested in microscopic-scale functional complementarity and mechanism closed-loop. It achieves four functional pathways: blocking salt toxicity through chelate channels, ensuring nutrient supply through complexation channels, enhancing nutrient absorption through root-promoting channels, and resisting stress damage through stress-resistant channels. Ultimately, it achieves the macroscopic effect of "improved soil physicochemical properties—enhanced root function—increased crop stress resistance and yield." Its core advantage lies in overcoming the functional limitations of single components and solving the industry pain points of "difficult-to-eliminate salt damage, easy nutrient loss, and unstable improvement effect" in saline-alkali land improvement through molecular-level synergistic effects.

This invention discloses a coffee shell solid-liquid dual-effect soil conditioner, its preparation method, and its full resource utilization method, belonging to the fields of agricultural solid waste resource utilization and soil improvement technology. The conditioner consists of a coffee shell biochar solid conditioner and a coffee shell liquid bio-conditioner. The solid conditioner is prepared by low-temperature anaerobic carbonization, pulverization, and compounding of coffee shells. The liquid conditioner is prepared by coffee shell pulping, anaerobic fermentation, enzymatic hydrolysis, filtration, dilution, and compounding. The liquid filtration residue is returned to the solid carbonization process, achieving 100% waste-free utilization of all components of the coffee shells. This invention provides a synergistic solid-liquid dual-effect, which can effectively repair the structure of acidic red soil, regulate pH, and achieve carbon sequestration, while simultaneously providing rapid soil nutrient replenishment and activating microorganisms, significantly improving soil fertility and the quality of tea and coffee crops. The process is simple, low-cost, and has high ecological value, making it suitable for the fields of agricultural waste resource utilization and green soil improvement.

This invention belongs to the field of agricultural mulch film technology, specifically relating to a liquid mulch film and its preparation method. The liquid mulch film provided by this invention comprises the following raw materials: lignite ethanol extract, lignite-based humic acid, emulsifier, film-forming agent, plasticizer, and water. By combining lignite ethanol extract, lignite-based humic acid, film-forming agent, and plasticizer, the liquid mulch film provided by this invention can improve the hydrophobicity and toughness of the resulting liquid mulch film, thereby enhancing its heat retention and moisture retention effects on the soil.

The application discloses a coal gangue-based sandy soil modifier and application thereof, and belongs to the technical field of soil improvement. The modifier is composed of a basic component and a composite component, wherein the basic component is coal gangue, and the composite component is composed of straws and rotten leaves. The mass percentage of the basic component is 1-5%, and the mass ratio of the straws to the rotten leaves in the composite component is (1-4):(1-4). The modifier provided by the application can simultaneously, quickly and durably increase the contents of organic matter, total nitrogen and total phosphorus in sandy soil, significantly improve the problems of loose structure, poor water and fertilizer retention capacity and extreme nutrient deficiency of the sandy soil, and improve the soil fertility from an extremely low level to a high level, thereby effectively overcoming the problems of single effect, poor nutrient synergy, short duration and high cost of the existing modifier. The modifier is suitable for ecological restoration and fertility improvement of flowing sandy land, semi-fixed sandy land and sandy farmland.

A corn and chive composite planting method belongs to the technical field of planting methods. The problems that water and soil loss is serious, biodiversity is reduced, and the income increasing pressure of farmers is large in existing corn single cropping are solved. According to the method, after previous crops are harvested, soil is subjected to deep ploughing or deep scarification in autumn, and fertilization is conducted; in spring of the second year, when the soil is thawed by 15-30 cm, pulp jacking and ridging are carried out, an allium fistulosum planting belt is arranged every 6-8 rows of corn planting belts, and the ratio of the corn planting belts to the allium fistulosum planting belt is (3.6-4.8 m): (1.2-1.5 m); planting the chive as soon as possible after the soil is completely unfrozen, ditching or digging holes in a chive planting belt, planting a cluster of division seedlings of the chive in each hole, treading after planting, and thoroughly watering for fixing roots; corn sowing is conducted 7-10 days after field planting of the allium fistulosum and when the ground temperature is stabilized to be 8 DEG C; and harvesting after the corn and the chive are mature. The method has the advantages of efficient utilization of resources, complementation of ecological functions, superposition of economic benefits and exertion of regional advantages.
