Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the current fertilization technology results in the lack of wheat seedlings and broken ridges, weak growth of wheat seedlings, reduced corn production, and fertilizer nutrients between crops and within the period under the condition of full return of two seasons of wheat and corn at medium and high yield levels. Unreasonable distribution leads to many problems such as reduced utilization rate and waste, environmental pollution, and reduced economic benefits. The present invention provides an i

Example Embodiment

[0041] Example 1: An integrated fertilization method under the condition of returning wheat stalks and corn stalks to the field, including returning wheat stalks to the field to sow corn, and returning corn stalks to the field to sow wheat. The steps are as follows:

[0042] (1) While harvesting the wheat, mechanically crush the wheat straw and cover the field with the wheat straw. Then, the no-tillage planter will sow the corn, stubble the wheat at the corn seedling stage, and fertilize at the corn seedling stage and the bell mouth stage;

[0043] (2) When the corn is mature, harvest the corn ears, crush the corn stalks and root stubble or combine the mechanical harvesting of the corn ears to crush the corn stalks and root stubble at the same time. The crushed corn stalks and root stubble are mixed evenly to cover the field, and then the soil is rotated or Deep ploughing and burying corn stalks, sowing wheat and applying fertilizer after soil preparation.

[0044] The effects of the...

[0053] Embodiment 2: An integrated fertilization method under the condition of returning wheat stalks and corn stalks to the field, including returning wheat stalks to the field to sow corn, and returning corn stalks to the field to sow wheat, the steps are as follows:

[0054] (1) While harvesting the wheat, mechanically crush the wheat straw and cover the field with the wheat straw. Then, the no-tillage planter will sow corn, stubble the wheat at the corn seedling stage, and fertilize at the corn seedling stage and the bell mouth stage;

[0055] (2) When the corn is mature, harvest the ears of corn, mix the crushed corn stalks and root stubble to cover the field uniformly, apply the fertilizer and bury the corn stalks and fertilizer deeply, and sow the wheat after the ground preparation.

[0062] Example 3: An integrated fertilization method under the condition of returning wheat and corn double crop stalks to the field, including returning wheat stalks to the field to sow corn, and returning corn stalks to the field to sow wheat, the steps are as follows:

[0063] (1) While harvesting the wheat, mechanically crush the wheat straw and cover the field with the wheat straw. Then, the no-tillage planter will sow corn, stubble the wheat at the corn seedling stage, and fertilize at the corn seedling stage and the bell mouth stage;

[0064] (2) When the corn is mature, the corn stalks are harvested by the combined machinery and the corn stalks and root stubble are crushed at the same time. The crushed corn stalks and root stubble are mixed to cover the field uniformly.

[0065] The effects of the overall dosage and distribution of K fertilizer on the yields and benefits of wheat and corn under the integrated fertilization method under the conditions of the above-mentioned two...

Abstract

The invention relates to an integrated fertilization method under the condition of NPKS of double-cropping crops of wheat and corn, comprising the NPKS of wheat to sow corn and the NPKS of corn to sow wheat. In the invention, under the conditions of NPKS of medium and high yield level of wheat and corn which can be harvested twice a year, the fertilization amount per mu is as follows: 25-32kg of N, 13-18kg of P2O5 and 13-18kg of K2O, the higher of the yield of the two crops, the greater of the application proportion of the nitrogen fertilizer therein on the wheat, while the allocation proportion of phosphorus and potassium is slightly different. The integrated fertilization method under the condition of NPKS can not only give consideration to complete and strong seedlings and high and stable yield of the two-cropping rotation crops of wheat and corn, but can also give full play to the positive influence of NPKS to increase soil organic matter and improve soil fertility, eliminating the negative influence, and can further reduce waste and environmental pollution caused by unreasonable input and allocation of chemical fertilizer.

Description

technical field [0001] The invention relates to a fertilization technology in the crop planting production process, in particular to an integrated fertilization method under the condition that all the stalks of double-ripened wheat and corn crops are returned to the field. Background technique [0002] Wheat / corn rotation cultivation in northern my country refers to the interplanting of summer corn in the late growth period of winter wheat in the same plot (mostly a few days before the mature harvest), or the direct seeding of summer corn after wheat harvesting, and summer corn in the A cultivation system in which winter wheat is planted after harvest in September and October, and two crops of grain can be harvested a year. At present, this kind of planting and cultivation mode has a relatively large sowing area in the Huanghuaihai River Basin such as Shandong, Henan, and Hebei. It is basically the main planting method in the above-mentioned provinces, and these provinces are...
