Because his one acre of land yielded 850 kilograms this year, this was considered high yield among hybrid rice crops.
Indeed, Southern had now begun popularizing hybrid rice, so for her family to achieve a yield of 850 kilograms per acre was already a high yield.
And other people's rice fields, using the same seeds, were yielding between 750 and 800 kilograms per acre. That is to say, did his method of fish farming in the rice fields really increase the yield?
So this year, Zheng Long generously bought seventy to eighty yuan's worth of loach fry to scatter into the rice fields. By doing this, once the loaches grew up, the root-knot nematodes, aquatic earthworms, mosquito larvae, and other aquatic pests became natural food for the loaches. The tiny loaches not only devoured the pests harming the rice but also loosened the soil around the rice roots, promoting rice growth and making an "indispensable" contribution to the increased yield.
