Embodiment 1

[0032] Weed resource utilization and green control tillage treatment adopt the following operations:

[0033] (1) Soil tillage: The soil adopts strip-shaped conservation tillage, that is, strip-shaped tillage is only carried out in the corn planting row area, and no-tillage is used between the corn rows. Specifically, 30cm wide and 15cm deep strips are cultivated in the corn planting row area, the no-tillage width is 70cm, and the no-tillage area accounts for 70% of the total ground area.

[0034] (2) Corn planting: choose Yunrui 668, a semi-diffuse variety of corn, and use wide rows and close planting with a row spacing of 100cm (enlarge the row width to make room for weeds to grow, and at the same time provide for mechanical mowing of weeds and management of poultry grazing and other weeds) Using conditions created), the density is 4764 plants per mu; two plants per hole are used to plant (improve the light environment between plants after close planting, and effectively red...

Embodiment 2

[0046] Weed resource utilization and green control tillage treatment adopt the following operations:

[0047] (1) Soil tillage: The soil adopts strip-shaped conservation tillage, that is, strip-shaped tillage is only carried out in the corn planting row area, and no-tillage is used between the corn rows. Specifically, 25cm wide and 20cm deep strips are cultivated in the corn planting row area, the no-tillage width is 45cm, and the vertical rows of adjacent two planting holes are displaced relative to the center line by 12cm.

[0048] (2) Corn planting: choose Yunrui 668, a semi-diffuse variety of corn, and use wide rows and dense planting with a row spacing of 80cm (enlarge the row width to make room for weeds to grow, and at the same time provide for mechanical mowing of weeds and management of poultry grazing and other weeds) Create conditions by using), use double planting per hole (improve the inter-plant light environment after close planting, effectively reduce the intra...

Embodiment 3

[0053] Weed resource utilization and green control tillage treatment adopt the following operations:

[0054] (1) Soil tillage: The soil adopts strip-shaped conservation tillage, that is, strip-shaped tillage is only carried out in the corn planting row area, and no-tillage is used between the corn rows. Specifically, 35cm wide and 25cm deep strips are cultivated in the corn planting row area, the no-tillage width is 75cm, and the vertical rows of adjacent two planting holes are displaced relative to the center line by 5cm.

[0055] (2) Corn planting: Yunrui 668, a semi-diffuse variety of corn, is used for dense planting in wide rows with a row spacing of 110cm (enlarge the row width to make room for weeds to grow, and at the same time provide for mechanical mowing of weeds and management of poultry grazing and other weeds. Use to create conditions); use double planting per hole (improve the light environment between plants after close planting, effectively reduce the intraspe...

Abstract

The invention discloses a cultivation method for resource utilization of weeds in a corn field, and belongs to the technical field of corn planting. From the perspective of weed resource utilization, the cultivation method for resource utilization and green control of the weeds in the corn field is provided and specifically comprises the steps that strip-shaped cultivation with the width of 25-35 cm and the depth of 15-25 cm is carried out in a corn planting row area; wide-row close planting and one-hole double-plant planting are adopted, the row spacing is 80-110 cm, the hole spacing is not smaller than 25 cm, and adjacent holes are staggered by 5-12 cm; weed mowing is carried out once before the corn sowing period, in the jointing period and in the flowering period respectively, mowing is carried out 2-4 times in the growing season, poultry are stocked between rows after mowing, and the mowed grass branches and leaves cover the ground surface of an original position or a corn root system area are moved out of the field to be used as various biomass raw materials required by processing; and the corn straw in the last year covers the ground surface of the corn root system area. According to the method, weed growth is promoted, resource utilization is achieved, meanwhile weed competition can be effectively inhibited, the corn yield equivalent to that of conventional cultivation is obtained, and the comprehensive productivity and sustainability of the corn field are improved.

Description

technical field [0001] The invention relates to a cultivation method for resource utilization and green control of weeds in a cornfield, belonging to the technical field of corn planting. Background technique [0002] Weeds in farmland are a major factor in reducing crop yields, and most crops lose more than 50% of their yield, or fail entirely, without protection from herbicides. Therefore, crop producers and researchers around the world have long been committed to eradicating weeds in farmland. At present, farmland weeding technology can be simply divided into two categories: one is to rely on various chemical herbicides, this weeding method has remarkable effects, is convenient and efficient to use, and has a wide range of applications. It has the most extensive application area in agricultural production in China and the world. However, it has potential adverse effects on the ecological environment of farmland; the other type is a variety of non-chemical weeding techniq...
