Embodiment 1

[0032] Embodiment 1. The applicant of the present invention has carried out the experimental research on the environmental protection no-tillage, cost-effective and efficiency-enhancing cultivation of common corn in Ganzhou District, Zhangye City, Gansu Province.

[0033] Variety selection: Due to the abundant sunlight, large temperature difference between day and night, and dry climate in the northwest region, the corn of the present invention needs to be cropped continuously for two years. In order to achieve high and stable yield, the selected variety should have a high utilization rate of light energy, a well-developed root system, and be able to fully absorb soil moisture and nutrients. Resistant to major soil-borne diseases. In this example, an excellent common corn variety "Fengyu No. 2" with high yield, good resistance and well-developed root system was selected. According to the resistance identification of Gansu Academy of Agricultural Sciences, this variety has high...

Abstract

The invention discloses an environment-friendly cost-saving and efficiency-increasing cultivation method for corn, belongs to the field of corn planting and cultivation, and solves the problems of environmental pollution and relatively high cost existing in traditional corn planting modes.The method comprises the following steps: ploughing and fertilizing after harvesting preceding crops in late autumn; rototilling the land and levelling in spring of the first year; applying a base fertilizer, setting a drip irrigation zone, mulching a film and sowing synchronously by using a united sowing machine at the first ten days of April, wherein a wide-narrow row planting method is adopted, the drip irrigation zone is set in the middle of narrow rows, and film mulching is performed on the narrow rows and not performed on wide rows; harvesting the corn in autumn with the stubble height of 5-8 cm, and paying attention to protecting the mulching film and the drip irrigation zone without removing the mulching film and the drip irrigation zone and ploughing; only sowing and fertilizing in the middle ten days of April of the second year, sowing seeds between the plant spacing of the preceding crops of corn, and fertilizing the fertilizer beside the film, wherein the planting density and the type and amount of the fertilization are the same as that of the first year, and two years are a cultivation planting cycle period.The invention provides the method with two years as a planting cycle period, so that environmental protection and cost saving are realized, and the economic benefit is increased.

Description

technical field [0001] The invention belongs to the field of corn planting and cultivation, and in particular relates to an environment-friendly, cost-effective and efficiency-enhancing cultivation method for corn. Background technique [0002] Maize (Zea mays L.) is an annual herbaceous plant belonging to the Poaceae Zea genus. According to the use and grain composition, it is divided into two categories: special corn and common corn. Maize is native to Central and South America and is one of the most widely distributed crops in the world. It is widely cultivated in areas from 58° north latitude to 35-40° south latitude. The largest cultivated area is in the United States, China, Brazil, Mexico, South Africa, India and Romania. It is planted all over the country. Corn is an annual monoecious cross-pollinated plant with tall plants and strong stalks. It is an important food, feed and economic crop. It is also the crop with the highest total output in the world. It has bec...
