Problems solved by technology

However, the current potato and corn are planted separately. This planting method has obvious agricultural consumption between two crops, which reduces the multiple cropping index, and the utilization rate of climate resources in the growing season is not sufficient. The economic benefits brought about by the excessive consumption of fertilizers are also average.

[0024] 1 Materials and methods

[0025] 1.1 Overview of the test site

[0026] 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.

Abstract

The invention belongs to the technical field of agricultural planting, and particularly relates to an efficient cultivation method for harvesting potatoes and fresh corn four times one year. The method is characterized in that according to the two-film planting characteristic of early spring potatoes, on the basis of sowing early spring potatoes and autumn potatoes, spring and summer two-season fresh corn is intercropped, and efficient cultivation of four times one year is carried out. The benefit obtained through matching the potatoes with different fresh corn improved varieties is better than that of common hybrid corn, the multiple cropping index of the land unit area is effectively improved, the land utilization rate is increased, the market blank of the fresh corn is filled, and the income sources of farmers are increased.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a high-efficiency cultivation method for harvesting potatoes and fresh corn all year round. Background technique [0002] Potatoes and corn are both important food crops in the world. At present, potatoes are planted in a relatively large area in Southwest Shandong, and they are planted in both early spring and autumn. However, the current potato and corn are planted separately. This planting method has obvious agricultural consumption between two crops, which reduces the multiple cropping index, and the utilization rate of climate resources in the growing season is not sufficient. The economic benefits brought about by the excessive consumption of fertilizers are also general. Contents of the invention [0003] In view of the above problems, the present invention proposes a high-efficiency cultivation method for potato and fresh corn harvested four t...
