Cultivation model of three-row peanut in large ridge and intercropped corn in furrows

Abstract

The invention relates to a cultivation model of three-row peanuts in a large ridge and intercropped corn in furrows, which is a novel scientific planting technology, changes the traditional planting method and simultaneously plants two kinds of plants with high and short stalks. The cultivation model of the three-row peanuts in the large ridge and the intercropped corn in the furrows comprises the following steps of planting peanuts in a ridge table, changing the original two ridges to one ridge, planting three rows of the peanuts in the ridge, and planting corn in the furrows. According to the cultivation model of the three-row peanuts in the large ridge and the intercropped corn in the furrows, the border effect of the corn is remarkable, and each corn is planted on the border so as to facilitate the crop rotation and the irrigation; complete stalks or high stubbles of the corn after the autumn can be reserved in the field to be utilized as wind curtains for stopping and slowing down the wind, so that the soil loss is released, meanwhile the soil organic matters are increased and the soil is fertilized; when the two kinds of plants are planted in a matching manner, the corn can keep out the wind and the cold, shade and prevent the drought for the peanuts; the root system of the corn is well developed and enjoys water and fertilizers, and after being planted in the furrows, the corn can fully absorb the rainwater in the furrows after raining and the lost fertilizer of a shallow surface layer, so that the growth of the corn is facilitated; the corn is planted in separate furrows, so that the ventilation effect is good, and the pest and disease damage is effectively prevented from occurring.

Description

technical field [0001] The invention belongs to crop cultivation in the field of agricultural technology, and in particular relates to a cultivation mode of peanut intercropping corn in three rows in a large ridge. Background technique [0002] The scientific name of peanut is ground peanut, and it is called longevity fruit among the people. It belongs to the leguminous crop and is known as "Chinese nut", "green milk" and "vegetarian meat". Because of its rich nutrition, it is known as "vegetable meat" and is a high-protein (32%) oil crop. Peanut is one of the few bulk crop varieties with net export in my country. my country's entry into the WTO will have a positive effect on the peanut export in the 21st century. After my country's accession to WTO, the export channels of peanuts will be further expanded, and the export volume will have broad prospects in the development of health food and medical food. [0003] Corn is the main food crop in Northeast China. It is an im...
