Abstract: Embodiments of the present disclosure provide a method and system for generating a fertilizer formula, the method is executed by a processor, comprising: obtaining a basic formula for fertilization; obtaining monitoring data based on a monitoring device; determining a soil feature of a predetermined point based on the monitoring data; determining an experiment scheme and experimental parameters based on the soil feature and an experimental design; determining a fertilization dosage and conducting an intelligent planting experiment based on the fertilization dosage and the basic formula for fertilization; obtaining experimental parameters and experimental yield data of each experimental processing, and optimized yield data of an optimized fertilization processing, and storing the experimental parameters, experimental yield data, and the optimized yield data in a storage unit; and determining a model for reduced fertilization of nitrogen, phosphorus, and potassium nutrients and generating the fertilizer formula

Abstract: A tissue culture method and a propagation method of Cathaya argyrophylla are described herein. An adventitious bud can be induced from an explant of the Cathaya argyrophylla using a suitable induction medium, with an induction rate reaching 69.22% to 73.33%. The induced adventitious bud is inoculated into a suitable proliferation medium, such that the adventitious bud can proliferate and strengthen seedlings, where the adventitious bud shows a proliferation rate reaching 46.23% to 55%. The adventitious bud after proliferation and seedling strengthening are inoculated into a suitable rooting medium to allow rooting culture, thereby obtaining a complete tissue culture seedling of the Cathaya argyrophylla. The tissue culture method is of great significance for protecting the Cathaya argyrophylla, increasing a plant quantity of the Cathaya argyrophylla, and expanding a population of the Cathaya argyrophylla to prevent extinction.

Abstract: A juicer and blender-compatible power device, comprising: a driving part used for generating power; a first driving shaf and a second driving shaft, wherein the first driving shaft rotates by means of the driving part, the second driving shaft is a hollow shaft, the first driving shaft penetrates the inside of the second driving shaft, and the second driving shaft rotates at a speed different from that of the first driving shaft; a supporting part, wherein end parts of the the first driving shaft and the second driving shaft protrude from a hole of the supporting part, and the second driving shaft may be rotatably supported on the supporting part; a first bearing arranged between the first driving shaft and the second driving shaft; and a second bearing arranged between the second driving shaft and the supporting part. The first bearing and the second bearing are arranged to overlap in the horizontal direction.

Abstract: The present disclosure relates to a driving apparatus for combined use of juicer and mixer, and the driving apparatus for combined use of juicer and mixer according to the present disclosure includes a driving part for generating power; a first driving shaft that is rotated by the driving part, and a second driving shaft having a hollow shaft through which the first driving shaft penetrates and rotating at a different speed from the first driving shaft; a support part that has a hole through which an end part of the first driving shaft and the second driving shaft protrude, and that rotatably supports the second driving shaft; a first bearing disposed between the first driving shaft and the second driving shaft; and a second bearing disposed between the second driving shaft and the support part, wherein the first bearing and the second bearing are disposed to overlap each other in a horizontal direction.

Abstract: Disclosed is a juice extractor capable of serving as a mixer, the juice extractor including a first motor (120) and a second motor (125) rotating at high speed; a first driving shaft (152) rotated at high speed by the first motor (120); a second driving shaft (154) disposed concentrically with the first driving shaft (152) as a dual shaft; and a main body (100) comprising a reducer disposed between the second driving shaft (154) and a motor shaft of the second motor (125) and reducing rotation speed of the second motor (125) to rotate the second driving shaft (154) at low speed; a mixer module (600) comprising a rotary blade (292) that couples with the first driving shaft (152) and rotates at high speed, and mounted to an upper portion of the main body (100); and a juice-extraction module (500) comprising a screw (300) that couples with the second driving shaft (154) and rotates at low speed, and mounted to the upper portion of the main body (100) in replacement of the mixer module (600).
