Example Embodiment

[0024] Example 1

[0025] In 2016-2017, at the Bohai Granary Test Base in Wudi County. After the corn is harvested, crush the stalks to less than 5 cm in length, and spread urea 1.5-2 kg / mu--water 65 square meters / mu--rotary tillage 2 times--choose Linmai No. 4, 25 kg / mu, On October 8, the sowing method with a row spacing of 15 cm and a seedling belt of 3-5 cm was adopted without watering overwintering water and greening water in the later stage. The average yield per mu of 4 mu of wheat is 263 kg.

Example Embodiment

[0026] Example 2

[0027] In 2016-2017, at the Bohai Granary Test Base in Wudi County. After the corn is harvested, use the sowing method of the present invention to crush the stalks to a length of less than 5 cm, and apply 1.5-2 kg / mu of urea--rotary tillage once-subsoiling, watering 105 cubic meters / mu-rotary tillage 2 times-pre-sowing suppression-choose Linmai No. 4, 45 kg / mu, and adopt the method of full-width sowing-timely suppression after sowing on November 1, and do not pour overwintering water and green water in the later stage.

[0028] The average yield of 4 mu of wheat is 456 kilograms per mu, which is 193 kilograms more than the comparison of embodiment 1 with 263 kilograms, an increase of 42%.

Example Embodiment

[0029] Example 3

[0030] In 2017-2018, in Bincheng Zhongyu Industrial Park. After the corn is harvested, crush the stalks to less than 5 cm in length, and apply 1.5-2 kg / mu of urea--water 53 square meters--rotary tillage 2 times--choose Jimai 22, 25 kg / mu, in October On the 7th, the sowing method with a row spacing of 15cm and a seedling belt of 3-5cm was adopted without watering overwintering water and greening water in the later stage, and the average yield of 1.8 mu of wheat was 338 kg per mu.

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...
