Embodiment

[0034] 1. Implementation time and place: Heji, Qujialing, Jingmen City, Hubei Province from 2019 to 2020.

[0035] This technology implements a total of 15 mu, and the technology field of the present invention is set, and compared with the local conventional planting technology field. Arranged in random blocks, with a total of 3 repetitions.

[0036] 2. Key points of implementation

[0037] (1) Soil preparation and ditching: At the beginning of April, combined with basal fertilizer application in the field, a rotary tiller was used to rotate the field by 15cm to 18cm. Use plow-type ditch openers to open vertical and horizontal ditches across the field according to the specification of about 20 cm wide to drain water and reduce waterlogging.

[0038] (2) Selection and planting of spring corn varieties: Fengken 139, an early-maturing variety suitable for machine harvesting (a variety suitable for planting in this area approved by the National Crop Variety Approval Committee), ...

Abstract

The invention discloses a density-increasing nitrogen-reducing efficient planting method for spring corn mixed cropping leguminous green manure, and belongs to the field of crop planting. According to the method, corn and leguminous green manure are mixed for cropping, so that the planting density is moderately improved, the input of a nitrogen fertilizer and a pesticide is reduced, the purpose of high yield and high efficiency of the corn is achieved, and powerful technical support can be provided for efficient production and green production of the corn.

Description

technical field [0001] The invention relates to a high-efficiency planting method for spring corn mixed with leguminous green manure to increase density and reduce nitrogen, and belongs to the field of crop planting. [0002] technical background [0003] In recent years, with the vigorous development of the aquaculture industry, the demand for feed has increased year by year. As the main source of feed in the middle reaches of the Yangtze River, corn has a large gap all year round and has been in a state of rigid demand. Therefore, the planting efficiency of corn is relatively high, which has stimulated the initiative of farmers to plant corn. With the increasing demand for corn and the adjustment of planting structure, the planting area and output of corn are increasing year by year. With the growth of social and economic conditions and market demand, the corn planting area in Hubei Province has continued to increase since 2003. By 2019, the province's corn planting area r...
