Please refer to Figure 5A. For example, after 128 days of planting, there is a significant difference between the ear weight of rice plants in the strain treatment group and the control group, that is, the strain helps to increase the ear weight of the plant.

Figure 5B shows a bar graph of the ear length of rice plants in the strain treatment group and the control group of the rice intensified cultivation system of the preferred embodiment of the present invention after planting. Please refer to Figure 5B. For example, after 128 days of planting, there is a significant difference between the ear length of rice plants in the strain treatment group and the control group, that is, the strain contributes to ear health and growth.

Figure 5C shows a bar graph of the thousand-grain weight of rice plants in the strain treatment group and the control group of the rice intensified cultivation system of the preferred embodiment of the present invention after planting. Please refer to Figure 5C, for example, in the colonization 128 After days, there was a significant difference in the thousand-seed weight of rice plants between the strain-treated group and the control group, that is, the strain helped to increase the thousand-seed weight of the plant.

Table 1. The concentration _{of NO 3} ^- in the soil of the conventional agricultural method and the two strain treatment groups of the present invention

As shown in Table 1, compared with the two strain treatment groups of the present invention, the conventional agricultural method has a _{higher concentration of NO 3} ^- . It is therefore speculated that on the 105th day, there are still too many nutrients that have not been fully absorbed before harvesting. In addition, in Table 1, it is obvious that the 30th day is the highest soil nutrient concentration in the entire rice growing period. In the probiotic treatment group, most of the nitrogen fertilizer has been used for 105 days of the test. Instead, a large amount of NO ₃ ^- remained after the harvest after using agricultural methods. In short, probiotics can increase the absorption efficiency _{of NO 3} ^{-by rice roots.}

Figures 6A to 6E show a series of images of the rice intensified cultivation system and its method according to the preferred embodiment of the present invention, which are executed in the experimental field, using the monitoring system and obtaining images of successful ear maturity to calculate the incidence rate. Please refer to Figures 6A to 6C, the three experimental plots of the present invention were investigated before the rice harvest in Houbi District, Tainan City. The rice growth potential was excellent and the ears were ready for harvest; please refer to Figure 6D, the present invention adopts A field detection system; please refer to Fig. 6E for sampling of foliar images to calculate the incidence rate.

Please refer to Figures 6A to 6E. For example, the incidence rate of leaves in the experimental field of the present invention is about 0.33%, while the incidence rate of the control group is about 3.76%. In addition, the rice intensified cultivation system and method of the present invention maintain a stable soil pH value at a weak acid condition suitable for crop growth.

The above experimental data are preliminary The results of the previous experiments are only used for easy understanding or reference to the technical content of the present invention, and other related experiments need to be carried out. The experimental data and results are not intended to limit the scope of rights of the present invention.

The foregoing preferred embodiments only illustrate the present invention and its technical features. The technology of this embodiment can still be implemented with various substantially equivalent modifications and/or alternatives; therefore, the scope of rights of the present invention shall be subject to a patent application. The scope defined by the scope shall prevail. The copyright in this case is restricted to the use of patent applications in the Republic of China.
