As the greatest invention of mankind, fertilizer has solved the problem of human hunger, leaving most people around the world to eat away from this difficult situation. However, in recent years, there have always been some noises in the society. Recently, some people in the society often circulate. The demonization of chemical fertilizers and pesticides, that people do not need fertilizers and pesticides, humans can still eat full stomach, still hungry, some people are also clamoring to return to the original agriculture, that production is not a problem.
In fact, these are full of hunger and hungry. The high yield of agriculture today depends not on primitive agriculture, nor on ecological agriculture. It is true to say that today, all human beings can eat full stomach, mainly relying on the selection of crop varieties, the use of chemical fertilizers, and the third is pesticides. usage of.
Then, in the absence of these three, what is the yield per mu of wheat and rice?
Due to the large regional nature of agriculture, the yield per mu of wheat and rice in different regions must be different. For example, if you don't use fertilizers and pesticides, or if you don't use the improved new varieties, the yield of wheat may be only half of the current, or even not, and rice is expected to be even worse.
The reduction in output is actually a trivial matter. There is no era of chemical fertilizers and pesticides. What is even more terrible is the loss caused by pests and diseases. Disasters such as locust plague and wheat rust may cause farmers to stop collecting overnight. This is definitely not alarmist.
Therefore, in the era of no fertilizers and pesticides, the output of grain is relatively low, and the second is very unstable. If it is not enough, it may not be enough.
