Yellow River Delta saline-alkaline land winter wheat water-saving yield-increasing sowing method

Abstract

The invention relates to the technical field of crop planting, in particular to a Yellow River Delta saline-alkaline land winter wheat water-saving yield-increasing sowing method. The method includessteps: treating previous-crop straw, performing primary rotary tillage once, deeply loosening, watering, performing secondary rotary tillage for 2-3 times, compacting before sowing, performing full-width sowing, and compacting at proper time after sowing. Linked technical steps are adopted for operation and supplement each other, promote each other and are scientific in design, the defects in existing winter wheat planting in Yellow River Delta regions are fully eliminated, and yield increase of winter wheat in the regions is realized on the basis of water saving.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a water-saving and yield-increasing sowing method for winter wheat in saline-alkali land in the Yellow River Delta. Background technique [0002] Winter wheat is one of the main cultivated crops in the Yellow River Delta region. The groundwater in most areas of the Yellow River Delta cannot be used for irrigation of wheat fields due to its high salinity, and the irrigation water in this area mainly depends on the water from the Yellow River. However, the availability of water from the Yellow River is unreliable, and there is often a lack of water when irrigation is needed in winter and spring; especially in some areas that are far away from the Yellow River or where the ditches diverting the Yellow River are not smooth, it is often impossible to irrigate winter water or turn green in time because the Yellow River water cannot reach the area. Drought or alkali return in whe...

However, the availability of water from the Yellow River is unreliable, and there is often a lack of water when irrigation is needed in winter and spring; especially in some areas that are far away from the Yellow River or where the ditches diverting the Yellow River are not smooth, it is often impossible to irrigate winter water or turn green in time because the Yellow River water cannot reach the area. Drought or alkali return in wheat fields due to excessive water, which has adverse effects on wheat production such as severe reduction or extinction
