Problems solved by technology

At present, the common corn planting methods are no-tillage planting and rotary tillage mixing. No-tillage planting can complete multiple measures such as sowing, fertilization, and suppression at one time. It has the advantages of saving energy and time. It has certain development potential in the North China Plain, but it is single all year round. No-tillage will also produce unfavorable conditions for crop growth, which will affect the growth and development of crops. Poor emergence and low emergence rate are the main reasons affecting the yield of no-tillage
Rotary tillage mixing leads to shallow plowing layer, reduced soil nutrient and water storage capacity, poor buffering capacity against stress, and prone to lodging, which is not conducive to stable and high yield

[0016] 1 Materials and methods

[0017] 1.1 Overview of the test site

[0018] The test field was started in 2015 at the long-term positioning base of Jining Academy of Agricultural Sciences (35°27’15”N, 116°35’11”E). The average annual precipitation in this area is 597-820mm, the annual average temperature is 13.3℃-14.1℃, and the frost-free period is 199 days. The soil in the test field is cinnamon soil. The main physical and chemical characteristics of the plow layer soil are: organic matter content 15.1g / kg, alkaline nitrogen 58.6mg / kg, available phosphorus 48.3mg / kg, available potassium 128.5mg / kg, pH value 6.98. The previous crop was wheat.

[0019] 1.2 Test materials and design

[0020] The corn variety Denghai 605 was selected for the experiment, which was sown on June 9, 2020 and harvested on October 6.

[0021] Design 1: After the wheat is harvested, the straw is fully plowed, that is, the straw is fully plowed after the wheat is harvested; the deep plowing depth ...

Abstract

The invention belongs to the technical field of agricultural planting, and particularly relates to a planting method for improving the growth and yield of corn. The planting method for improving the growth and yield of the corn is characterized in that straw full-amount deep tillage treatment operation is performed after wheat is harvested; the corn is sown after the operation is completed, and the full-amount deep tillage depth of straw is not smaller than 30 cm. By adopting the planting method for improving the growth and yield of the corn, the soil structure and permeability can be improved, corn root growth and water and fertilizer absorption and utilization are facilitated, high yield and high efficiency are achieved, and technical support is provided for large-area efficient green production of summer corn.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a planting method for improving the growth and yield of corn. Background technique [0002] The Huang-Huai-Hai region is the main grain-producing area in my country, especially the typical cropping system of winter wheat and summer corn, which is a two-cropping system in one year, is the main grain planting method in this area. The food products produced have greatly guaranteed the food security of our country. At present, the common corn planting methods are no-tillage planting and rotary tillage mixing. No-tillage planting can complete multiple measures such as sowing, fertilization, and suppression at one time. It has the advantages of saving energy and time. It has certain development potential in the North China Plain, but it is single all year round. No-tillage will also produce unfavorable conditions for crop growth, which will affect the growth a...
