Provided is a method for cultivating low potassium leafy vegetables at high yield without causing growth failure due to potassium deficiency in hydroponics. Cultivation is performed using a hydroponic solution containing a very small amount of potassium in the late cultivation period of low potassium leafy vegetables, thereby keeping the potassium content low at the time of harvest and also allowing the leafy vegetables to be stably harvested at high yield without causing potassium deficiency.
摘要:
To provide a plant water dynamics sensor usable for measuring the dynamics of water flowing in a fine point of a plant such as a distal end of a new branch or a pedicel. The plant water dynamics sensor comprises: a heater-equipped temperature probe 10 including a temperature sensor 11 and a heater 12; a temperature probe 20 including a temperature sensor 21; an electrical resistance probe 30 including an electrical resistance measurement electrode 33; and a support 80 that supports the probes 10, 20, and 30 while the probes are aligned parallel to each other. The position of a xylem XY can be detected based on an electrical resistance measured at the electrical resistance probe 30, so that each of the temperature sensors 11 and 21 can be arranged correctly in a position at a phloem PH or at the xylem XY. This facilitates attachment of a plant water dynamics sensor 1 and water dynamics in a plant can be measured with high accuracy.

The present application provides: a microbial material for agricultural use characterized by containing, as an active ingredient, Bacillus subtilis C-3102 strain (FERM BP-1096) that is capable of promoting the growth of crops and/or increasing the yield of crops, or a variant thereof that has an ability equivalent thereto; and a method for cultivating crops characterized by comprising cultivating the crops using a soil or medium that contains the microbial material.
摘要:
The present invention relates to a process for in vitro micropropagation of plant material comprising the steps of multiplication and elongation of shoots developed from plant propagules. The invention further comprises a process for the production of clonal seedlings plants on a large-scale ready for field development as replacements of traditional clonal gardens by 'in vitro' biofactories.

Provided are a plant management system and a plant management method, which do not entail a substantial workload, cost, construction period, or installation space; enable a system to be easily constructed, altered and expanded; have a small maintenance load; enable processing systems to be distributed and arranged in geographically separate locations and in locations where connecting the processing systems is not easy; and are capable of preventing the occurrence of large-scale problems. A plant management system 100 has: a plurality of processing systems 140, 150; and memory tags 112, 122, wherein processing systems 140, 150 include reader-writers 142, 152, 153 and processing devices 141, 151, and, by writing plant management data into the memory tag 112 by means of the reader-writer 142 and then reading the plant management data by the reader-writer 152 of the processing system 150, the plant management data is transferred between the processing systems 140, 150.
摘要:
[Problem to Be Solved] To provide a plant growth promotion device having a simple configuration, which can promote the growth of good tasting, high quality crops. [Means for Solving the Problems] A plant growth promotion device comprises: a flat-plate rotor 1; and a motor 2 coupled this rotor 1 by a rotary shaft 2a, wherein a plurality of permanent magnets 1 a are configured so as to be fixed in place at arbitrary intervals within the rotor 1, and the rotor 1 is rapidly rotated by the rotary shaft 2a that is coupled to the motor 2, so as to produce an alternating magnetic field in the surroundings of an agricultural field for crops.
