5results about How to "Reduce nutrient loss" patented technology

The utility model relates to seedling planting equipment technical field, and disclose a kind of soil fertilization device for seedling planting, the soil fertilization device for seedling planting, including cylinder, the bottom of the cylinder is provided with fertilization subassembly, and fertilization subassembly includes annular spade, vertical rod, annular part, outer tube, slot, pressure rod, unfolding part, soil loosening cone.The soil fertilization device for seedling planting, annular fertilization can bypass main root, concentratedly throw on lateral root absorption zone, make fertilizer and high absorption zone match, greatly improve fertilizer utilization, realize closed conveying and positioning fertilization, prevent outside pollution and waste, the whole process avoids fertilizer exposure, reduces nutrient loss, improves utilization, rotates soil loosening cone and loosens soil, let soft soil automatically collapse or turn up and cover on fertilizer, reduce nitrogen fertilizer volatilization, phosphorus and potassium are fixed or nutrient is washed away by rainwater risk, significantly improve fertilizer efficiency duration and utilization.

The utility model discloses an ensiling cooling tank, including cooling tank and bottom plate, cooling tank is installed at the top of bottom plate, the interior of cooling tank is set to be cavity structure, the exterior of cooling tank is equipped with the inflation component that is used for filling nitrogen into the interior of cooling tank, one end of inflation component extends into the interior of cooling tank, and the other end of inflation component extends into the interior of cooling tank. According to the fresh-keeping device, nitrogen replacement of the inflation assembly can quickly reduce the oxygen concentration, restrain microorganism breeding and form a synergistic fresh-keeping effect with low temperature, meanwhile, the temperature of the cooling tank can be lowered, and the temperature of the cooling tank can be lowered. According to the device, an accurate temperature, gas concentration and pressure monitoring system is adopted, the cooling assembly and the inflation assembly can be regulated and controlled in real time, rapid and uniform cooling is achieved, the fresh-keeping effect is lasting, the quality of silage is remarkably improved, the storage life of the silage is remarkably prolonged, and the nutrition loss and putrefaction risk is reduced.

The present application belongs to the technical field of food processing, and particularly relates to a novel meat chunk sausage making method. The present application takes pig hind leg meat and fat as raw materials, mixes the meat chunks after curing and baking with cured meat paste and auxiliary materials, cooks the mixture after being filled into casing, and obtains the novel meat chunk sausage. The present application controls the temperature of the baked meat chunks, makes the myofibrillar protein denature moderately and gradually begin to coagulate and crosslink to form a weak gel, and then through secondary heating after mixing with the meat paste, makes the meat chunks and the meat paste fully interact and polymerize to form a stable three-dimensional network gel structure, and endows the product with good texture and taste. The results of the examples show that the novel meat chunk sausage made by the present application has strong internal tearing feeling, is firm and elastic, has smooth cutting surface, and has rich taste levels.

The application discloses a refrigerator and a thawing control method of the refrigerator. The refrigerator is provided with a thawing chamber for storing and thawing food to be thawed; a temperature sensor for detecting the temperature of the food to be thawed; a thawing device for thawing the food to be thawed when starting to operate; in response to a preset thawing control instruction, the total thawing time set at present and the set temperature of the food to be thawed are obtained; the process of thawing the food to be thawed from an initial temperature to the set temperature is divided into several temperature stages, the operating parameters of the thawing device in each temperature stage are determined, and the thawing device is controlled to operate according to the corresponding operating parameters in each temperature stage. By using the application, the operating state of the thawing device can be controlled according to the thawing requirements of each temperature stage in the food thawing process, so that the nutrient loss of the thawed food is reduced while the thawing requirements are met.

The application discloses a dry land spring maize planting method and application, and relates to the field of agricultural technology. The method comprises the following steps: rotary tillage after spreading fertilizer on a planting site; land preparation before sowing and setting wide rows and narrow rows, and covering the wide rows with mulching film; planting on the wide rows after covering the mulching film; and laying soil moisture sensors. The fertilizer comprises a high-molecular water-retaining agent and a nutrient base. The dry-land water-saving and synergistic fertilizer is organically combined with the ridge and furrow rain collection and mulching technology. The ridge and furrow rain collection efficiently collects rainfall in the crop root zone, and the mulching film significantly reduces evaporation loss. The dry-land water-saving and synergistic fertilizer further absorbs and retains water, forming a complete water management system of "water collection, water retention and water supply", so that efficient collection and utilization of natural rainfall are realized, water and fertilizer supply are strengthened, and the planting density under limited water conditions is improved.
