Problems solved by technology

[0002] my country is a large agricultural country, and winter wheat and summer corn are two important food crops in our country. In order to meet the requirements of high-yield winter wheat and summer corn and the law of fertilizer and water requirements, currently in the rotation of winter wheat and summer corn, wheat and corn are fertilized separately without consideration Depending on the use of fertilizers, multiple fertilization, topdressing, and watering are required, and the utilization rate of fertilizers is low, and the labor intensity and cost of fertilization are also high, which is extremely unsuitable for the reality of my country's rural labor shortage.

Embodiment Construction

[0065] Below in conjunction with embodiment the present invention is further described.

[0066] The amount of fertilization per hectare per year in middle-production fields is: pure nitrogen (N) 420kg-500kg, phosphorus (P 2 o 5 )210kg~260kg, Potassium (K 2 O) 300kg~350kg, zinc sulfate (ZnSO 4 )60kg~80kg, add 30000kg of high-quality organic fertilizer;

[0067] The amount of fertilization per hectare per year in high-yielding fields is: pure nitrogen (N) 550kg-600kg, phosphorus (P 2 o 5 )240kg~300kg, Potassium (K 2 O) 330kg~380kg, zinc sulfate (ZnSO 4 )60kg~80kg, organic fertilizer 45000kg;

[0068] The method includes a wheat planting method and a corn planting method;

[0069] Described wheat planting method comprises the following steps:

[0070] ①Wheat sowing

[0071] Seed selection: Choose winter or semi-winter varieties with high productivity per plant, lodging resistance, disease resistance, and stress resistance; under medium-yield field conditions, it is adv...

Abstract

The invention discloses a water-saving fertilizer-saving method for crop rotation of winter wheat and summer maize and belongs to the technical field of agriculture. The water-saving fertilizer-saving method comprises a wheat planting method and a maize planting method, wherein the wheat planting method and the maize planting method both comprise steps of seeding, fertilizing, irrigating, field management, chemical weeding, pest control, harvesting and the like, and all the wheat and maize straws are returned to the fields. By means of the water-saving fertilizer-saving method, the effect of water saving, fertilizer saving and high yield is improved, the fertilizer utilization rate is increased, and fertilizing labor intensity and cost are reduced.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a water-saving and fertilizer-saving method for winter wheat and summer corn rotation. Background technique [0002] my country is a large agricultural country, and winter wheat and summer corn are two important food crops in our country. In order to meet the requirements of high-yield winter wheat and summer corn and the law of fertilizer and water requirements, currently in the rotation of winter wheat and summer corn, wheat and corn are fertilized separately without consideration Depending on the use of fertilizers, multiple fertilization, topdressing, and watering are required, and the utilization rate of fertilizers is low, and the labor intensity and cost of fertilization are also relatively high, which is extremely unsuitable for the reality of labor shortage in rural areas in my country. Therefore, aiming at the development status of agricultural economy an...
