Introduction to dry farming

Dry farming refers to a rain-fed agriculture that mainly relies on natural precipitation to engage in agricultural production in semi-arid and semi-humid arid areas without irrigation conditions. For a long time, our agricultural research mainly focused on irrigated land, but relatively neglected the improvement of agricultural yield-increasing technology in dry land. This is because the effect of increasing production by irrigation is obvious. However, with the development and utilization of water resources, the continuous expansion of irrigation area is close to the limit. Now, we must attach great importance to the improvement of yield-increasing technology in dry land. Production practice in various places shows that the dry farming in northern China has great potential for increasing production, and its improvement technical measures mainly include the following nine kinds:
