Balanced fertilization method under condition of wheat/corn one-year-two-harvest cultivation total straw returning

The invention relates to a balanced fertilization method under the condition of wheat/corn one-year-two-harvest cultivation total straw returning. In the winter wheat season, corn ears are harvested when corn is ripe, straw and root remains are smashed, or the straw and the root remains are smashed while the corn ears are harvested by a machine, the corn straw and the root remains are smashed once again before soil preparation, base fertilizer is applied, soil is subjected to rotary tillage or is subjected to ploughing to bury the corn straw, then rotary tillage is conducted, wheat is sown, and topdressing is carried out in the jointing stage; in the summer corn season, wheat is harvested by the machine when being ripe, meanwhile, wheat straw is smashed, the wheat straw is made to cover the field, then corn is subjected to no-till machine seeding or manual dibble seeding, wheat stubble cleaning is carried out at the corn seedling stage, topdressing is performed at the belltop stage and the anthesis maturity period, or the corn is subjected to no-till machine seeding, meanwhile, seed fertilizer is applied, and topdressing is performed at the belltop stage and the anthesis maturity period. According to the balanced fertilization method, wheat and corn are used as one fertilization unit, the fertilizing amount and the fertilizing method are balanced, the full stand and healthy seedling and the high and stable yield of wheat and corn are guaranteed, soil organic matter is increased, the soil fertility is raised, sustainable highyield is achieved, and the fertilizer utilization efficiency is improved.

Preparation method of multilayer-coated slow release fertilizer for wheat

The invention discloses a preparation method of a multilayer-coated slow release fertilizer for wheat. The preparation method comprises the following steps: uniformly mixing a nitrogen fertilizer, a nitrogenous fertilizer synergist, a phosphate fertilizer, a potash fertilizer, medium trace element fertilizer and auxiliary materials, adding modified cassava powder as a binder, crushing, and granulating to obtain core particles; carrying out aging reaction on concentrated sulfuric acid, phosphoric acid and liquefied ammonia to obtain slurry, coating the core particles with the slurry as an internal coating material so as to form particles with the internal coating layer; humidifying the particles with the internal coating layer, adding an external coating material to uniformly coat the particles with the internal coating layer so as to obtain particles with an external coating layer, drying, polishing, and sieving to obtain the multilayer-coated slow release fertilizer for wheat. The multilayer-coated slow release fertilizer for wheat can fully supply wheat with nutrients. The supply of nutrients is lasting and harmonious, and release of nutrient elements can be controlled. Topdressing is not required by one-time fertilization. By the use of the fertilizer, quality and yield of wheat are remarkably enhanced.

Polypeptide fertilizer synergistic agent and preparation method thereof

The invention discloses a polypeptide fertilizer synergistic agent, relating to a fertilizer synergistic agent, namely a broad-spectrum plant nutrient absorption promoter, particularly a polypeptide fertilizer synergistic agent and a preparation method thereof which are applicable to agriculture production, flower culture and plant husbandry. The synergistic agent is prepared by evenly mixing poly potassium aspartate with calcium powder according to a mixture ratio, and the weight percentage mixture ratios of materials are as follows: 0.7-5 percent of poly potassium aspartate, 84-91.3 percent of calcium powder and the balance of water; and the total amount is 100 percent. The preparation method of the polypeptide fertilizer synergistic agent comprises the steps of weighing the materials of the poly potassium aspartate, the calcium powder and the water according to mixture ratio, putting the calcium powder weighed by mixture ratio into a stirring mixer, dissolving the poly potassium aspartate in the water to form a solution, evenly spraying the solution on the calcium powder, fully stirring and mixing, then balling and granulating; screening for ensuring granularity; and drying in a rotary drum dryer with drying temperature of 110-130 DEG C, air-extracting cooling to achieve normal temperature, then measuring and packing, thus preparing the polypeptide fertilizer synergistic agent.

Anti-tumor nano-adjuvant based on cross-linked biodegradable polymer vesicles and preparation method and application thereof

The invention discloses an anti-tumor nano-adjuvant based on cross-linked biodegradable polymer vesicles and a preparation method and application thereof. The nano-adjuvant is obtained by loading drugs with reversibly cross-linked biodegradable polymer vesicles with asymmetric membrane structure. The drug is an oligonucleotide capable of activating the immune response. Degradable polymer vesiclesare obtained by cross-linking after self-assembly of polymers. The molecular chain of the polymer includes successively connected hydrophilic segments, hydrophobic segments and positively charged molecules. The hydrophobic segments are polycarbonate segments and/or polyester segments that are compounded and loaded with drugs through electrostatic interaction. The film is a polycarbonate and/or polyester segment that is reversibly cross-linked, biodegradable and biocompatible. The side chain of dithiolane is similar to natural antioxidant lipoic acid of the human body. The outer shell is basedon PEG, and can target cancer cells. The adjuvant is expected to become a nano-vaccine or nano-immune adjuvant that integrates the advantages of simplicity, stability, and multi-function, and can be used for efficient tumor immunotherapy.

Production technology of low-salt dried small shrimps

The invention discloses a production technology of low-salt dried small shrimps. The invention belongs to the field of foodstuff processing. The technology comprises main steps of washing, steaming, vacuum drying, and vacuum packaging. According to the invention, a sectioned salting method is adopted, namely separated steps of steaming salting and drying salting are carried out. Salt content of the dried small shrimps is controlled, such that a low salt (wherein a salt content is lower than 5%) purpose is achieved. The vacuum dying technology is adopted. Small shrimps are uniformly spread, and are subject to vacuum drying under a temperature of 55-60 DEG C for 25-30min; salt water with a mass percentage concentration of 1-2% is uniformly sprayed onto the surface of the dried small shrimps; the dried small shrimps are subject to vacuum drying under a temperature of 70-75 DEG C for 15-20min, wherein a vacuum degree is 0.04-0.05MPa; the dried small shrimps are filled in a high-barrier and low-air-permeability packaging material, and is subject to vacuum packaging. According to the invention, the prepared dried small shrimps are advantaged in low salt, good plumpness, fleshy fullness, low nutrient loss, and low head breakage rate, and the like. Therefore, the dried small shrimps have relatively large application and popularization values.
