Flowers in crops depend entirely on the source of fertilizer;

Since ancient times, the growth of all crops can not be separated from the four factors of light, temperature, humidity and fertilizer. In the traditional farming period, the first three natural factors are almost impossible for farmers to change. Although irrigation can sometimes be used to change the moisture of crops, it is still useless if there is not enough fertilizer supply.

Therefore, if farmers want to increase crop production and income, the only thing they can change is to increase the fertilizer that provides nutrients for crops, so there is this agricultural proverb, "A flower in a crop depends on fertilizer."
