Problems solved by technology

At the same time, the temporal and spatial distribution of water resources in my country is extremely unbalanced. The northern region, which accounts for 64% of the total cultivated land, only has 19% of water resources, and the per capita water resources are less than 500m 3 serious shortage of water for agricultural irrigation
Compared with the traditional single planting method, this method can save water and increase production to a certain extent. However, in the prior art, flood irrigation is used for irrigation. uniform, deep seepage
Although it is suitable for narrow row dense crops such as wheat and millet, it uses more water
[0006] Traditional flat farming uses chemical fertilizers, and the amount of fertilizers remains high, resulting in waste of fertilizers and chemical pollution, which increases the cost of planting

Embodiment 1

[0019] (1), ridges are set in the field, the bottom width of the ridge is 77cm, the width of the ridge surface is 57cm, the height of the ridge is 14cm, and the width of the ridge is 10cm;

[0020] (2), sow 3 rows of wheat on the ridge surface, and the row spacing of wheat is 18cm;

[0021] (3), 25 days before the wheat harvest, interplant 1 row of peanuts between each row of wheat on the ridge;

[0022] (4) In the furrows, small water infiltrates and irrigates. The flood irrigation is changed to small water infiltration irrigation in the furrows, which greatly reduces the water consumption and effectively avoids the problems of field surface erosion, hardening, uneven irrigation, and deep seepage.

[0023] (5) Apply fertilizer along the furrow. Compared with the chemical fertilizer application used in traditional flat farming, the ridge cultivation described in this method, the fertilization is carried out along the furrows, which can also be called "strip application", whi...

Embodiment 2

[0026] (1), set ridges, ridge bottom width 80cm, ridge surface width 60cm, ridge height 15cm, ridge width 13cm;

[0027] (2), sow 3 rows of wheat on the ridge surface, and the row spacing of wheat is 20cm;

[0028] (3), 30 days before wheat harvest, interplant 1 row of peanuts between each row of wheat on the ridge;

[0029] (4) In the furrows, small water infiltrates and irrigates. The flood irrigation is changed to small water infiltration irrigation in the furrows, which greatly reduces the water consumption and effectively avoids the problems of field surface erosion, hardening, uneven irrigation, and deep seepage.

[0030] (5) Apply fertilizer along the furrow. Compared with the chemical fertilizer application used in traditional flat farming, the ridge cultivation described in this method, the fertilization is carried out along the furrows, which can also be called "strip application", which improves the utilization rate of fertilizers and effectively reduces the amoun...

Abstract

The invention relates to a one ridge two crops water saving and yield increasing cultivation method for wheat and peanut two cropping system, belonging to the technical field of agriculture. The method is characterized in that, ridges are arranged on field blocks; wheat is planted in rows on the ridges, and peanut is interplanted among the rows of wheat on the ridges; furrows are arranged among the ridges, and furrow irrigation is performed regularly. The one ridge two crops water saving and yield increasing cultivation method for wheat and peanut two cropping system has the advantages that, the traditional flatten culture of wheat and peanut two cropping system is changed to ridge culture; through dual-purpose ridge, furrow irrigation and row application, the unification of high yield, water saving and fertilizer saving of wheat and peanut is realized.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a water-saving and yield-increasing cultivation method for double cropping of wheat and peanuts, one ridge and two crops. Background technique [0002] my country is a country seriously short of water resources, the national per capita water resources in 1949 was 4800m 3 , dropped to 2300m by 1996 3 , which is only a quarter of the world's average level, ranking 88th in the world, and has been included in the list of 13 water-poor countries in the world. At the same time, the temporal and spatial distribution of water resources in my country is extremely unbalanced. The northern region, which accounts for 64% of the total cultivated land, only has 19% of water resources, and the per capita water resources are less than 500m 3 , a serious shortage of water for agricultural irrigation. [0003] As one of the main plants in northern my country, wheat is a crop that requires...
