Example Embodiment
[0024] Example 1:
[0025] A water-saving cultivation method of corn for both grain and feed, including the following steps:
[0026] 1) Set up at least three plots, each plot consists of 15 ridges, each ridge is 1100cm long, 60cm wide, and 20cm high; the plant spacing on each ridge is 30cm; the row spacing is 40cm;
[0027] 2) In step 1), there is a 150cm-wide moisture isolation belt between each plot, and a 40cm-wide irrigation ditch is set between each ridge;
[0028] 3) Use shed film to prevent seepage between the moisture isolation belts in step 2), cover the ridges in step 2) with agricultural mulch film, and cover the furrows between the ridges in step 2) with a thickness of 4 cm Corn stalks.

Example Embodiment
[0030] Example 2:
[0031] A water-saving cultivation method of corn for both grain and feed, including the following steps:
[0032] 1) There are at least three plots, each plot is composed of 15 ridges, each ridge is 1150cm long, 70cm wide, and 15cm high; the plant spacing on each ridge is 35cm; the row spacing is 50cm;
[0033] 2) In step 1), there is a 150cm-wide moisture isolation belt between each plot, and a 50cm-wide irrigation ditch is set between each ridge;
[0034] 3) Use shed film to prevent seepage between the moisture isolation belts in step 2), cover the ridges in step 2) with agricultural mulch film, and cover the furrows between the ridges in step 2) with a thickness of 4 cm Corn stalks.

Example Embodiment
[0036] Example 3:
[0037] A water-saving cultivation method of corn for both grain and feed, including the following steps:
[0038] 1) There are at least three plots, each plot is composed of 15 ridges, each ridge is 3000cm long, 65cm wide, and 18cm high; the plant spacing on each ridge is 32cm; the row spacing is 45cm;
[0039] 2) In step 1), a moisture isolation belt with a width of 150cm is set between each district, and an irrigation ditch with a width of 45cm is set between each ridge;
[0040] 3) Use shed film to prevent seepage between the moisture isolation belts in step 2), cover the ridges in step 2) with agricultural mulch film, and cover the furrows between the ridges in step 2) with a thickness of 4 cm Corn stalks.
[0041] After the above steps, the soil water holding capacity in the field is measured, combined with the calculation of the crop water requirement model and other calculations. The full furrow irrigation quota for grain and feed corn is 4500 m 3 / hm 2 Based...
