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 integrated fertilization method under the condition of returning all straws of wheat and corn to the field. The integrated fertilization method This method can not only take into account the full and strong seedlings, high and stable yield of wheat and corn rotation crops, but also give full play to the positive impact of returning straw to the field to increase soil organic matter, eliminate its negative impact, and reduce the unreasonable input and distribution of chemical fertilizers. waste and environmental pollution, and improve ecological and economic benefits

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.

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...
