Embodiment 1
[0041] Example 1: An integrated fertilization method under the condition of returning all the stalks of double-cooked wheat and corn crops to the field, including returning the wheat stalks to the field to sow corn, and returning the corn stalks to the field to sow wheat. The steps are as follows:
[0042] (1) mechanically pulverize wheat straw while harvesting wheat, cover the field with wheat straw, and then sow corn with a no-tillage seeder, perform wheat stubble removal at the corn seedling stage, and fertilize at the corn seedling stage and bell mouth stage;
[0043] (2) When the corn is mature, harvest corn ears, crush corn stalks and root stubble or combine machinery to harvest corn ears and crush corn stalks and root stubble at the same time, mix the crushed corn stalks and root stubble to evenly cover the field, and then, rotary till the soil or Deep plowing and burying of corn stalks, after soil preparation, sow wheat and apply fertilizers at the same time.
