Abstract

The invention belongs to the field of crop planting, in particular to a high-efficiency corn cultivation method in saline-alkali land. The high-efficiency corn cultivation method in the saline-alkaliland includes the following specific cultivation steps: soil improvement, flat land preparation and application of base fertilizer, corn sowing and film covering, irrigation and fertilization. The method achieves the aim of improving corn emergence rate, seedling preservation rate, water and fertilizer utilization efficiency and further improving corn yield by improving the corn planting method and optimizing the irrigation and fertilization system, breaks through the technical bottleneck of difficult corn planting and improvement in saline-alkali land in low-lying areas, and can play a technical supporting role in efficient improvement and utilization of saline-alkali land and improvement of ecological environment. On the one hand, ridge film furrow planting can effectively reduce the evaporation and consumption of soil moisture, and thus water collection and moisture preservation are favorable, so that crop yield and water use efficiency are improved; on the other hand, the utilization of groundwater can be further promoted, the groundwater level is lowered, and the phenomenon of soil salinization is reduced.

Description

[0001] Technical field:

[0002] The invention belongs to the field of crop planting, and in particular relates to a high-efficiency cultivation method for corn in saline-alkali land.

[0003] Background technique:

[0004] Water-saving irrigation is an important measure to ensure my country's food security and promote the sustainable use of water resources, and it is also an inevitable requirement for changing the mode of economic development and promoting the development of agricultural modernization. Since the beginning of the new century, more than a dozen "Central No. 1 Documents" have made water-saving irrigation a major strategy. Ningxia is located in the northwest inland, with drought and little rain. It is an area seriously short of water resources. Water issues have always been the basic and strategic issues of Ningxia's economic and social development. "Several Opinions of the State Council on Further Promoting Ningxia's Economic and Social Development" puts forward ...
