Abstract

The invention discloses a water-saving irrigation method applicable to close-planting crop. The water-saving irrigation method is particularly applicable to wheat and hybrid millet and comprises the procedures that A, soil preparation, sowing and fertilization are carried out; B, a separate-field limited irrigation method is adopted to carry out irrigation when the crop is in the jointing-booting stage, and two adjacent fields are respectively irrigated with the normal water quantity and one third to two thirds of the normal water quantity; and the normal water quantity is 40-100 mm; and C, the separate-field limited irrigation method is adopted to carry out irrigation when the crop is in the filling stage, and the two adjacent fields are respectively irrigated with one third to two thirds of the normal water quantity and the normal water quantity, namely the field which is irrigated with the normal water quantity last time is irrigated with one third to two thirds of the normal water quantity this time, and the field which is irrigated with one third to two thirds of the normal water quantity last time is irrigated with the normal water quantity this time. According to the water-saving irrigation method applicable to close-planting crop, the water consumption used for irrigation is greatly reduced, and a certain yield-increasing effect is also played on the crop.

Description

technical field

[0001] The invention relates to the technical field of water saving in agricultural planting, in particular to a water saving irrigation method suitable for densely planted crops. Background technique

[0002] Water scarcity is the primary agricultural and ecological problem facing the world. Drought is a global problem that seriously affects world food security. Global climate change makes this situation even more critical. According to a report released by UNESCO at the Fifth Water Resources Forum, if the world does not improve the efficiency of water resource utilization, half of the world's population will live in a water-scarce environment by 2030. For a long time to come, the lack of water resources in some arid and semi-arid regions will have a major impact on population mobility. It is estimated that 24 million to 700 million people will be displaced due to water shortage.

[0003] my country's per capita and per mu water resources are far below the ...
