Potato-vicia sativa intercropping method under water and fertilizer regulation and control for ensuring stable yield and high quality of potatoes and fertilizing soil

Abstract

The invention discloses a potato-vicia sativa intercropping method under water and fertilizer regulation and control for ensuring stable yield and high quality of potatoes and fertilizing soil. The method comprises the following steps of (1) adopting high-ridge double-row planting in mid-to-late April every year, planting two rows of potatoes on ridges, applying compound fertilizer, planting vicia sativa in furrows, applying nitrogen fertilizer to green manure rows, and laying drip irrigation belts; (2) irrigating in the middle of June; (3) irrigating in late June; (4) crushing the vicia sativa in a full-bloom stage, and turning and pressing the crushed vicia sativa on ridges for decomposition; (5) irrigating in the middle of August; and (6) irrigating in early September. According to the method, the potato yield can be guaranteed, the potato quality can be improved, the soil fertility can be improved, and the goals of replacing large fertilizer with small fertilizer and repairing while producing are achieved. Through the implementation of the mode, the efficient and sustainable production of the potatoes in the Inner Mongolia region can be realized.

Description

technical field [0001] The invention relates to the field of crop planting, and relates to a method for intercropping potatoes and arrowhead peas under the control of water and fertilizer to ensure stable yield and high quality of potatoes while fertilizing soil. Background technique [0002] Irrigation and fertilization are two key factors affecting crop production. At present, the potato industry in Inner Mongolia Autonomous Region has the problems of low potato yield per unit area and low resource utilization efficiency, which are manifested in the shortage of water resources, low water use efficiency in main production areas, and unbalanced input of chemical fertilizers. Long-term continuous cropping of potatoes, excessive application of nitrogen fertilizers and unreasonable irrigation make the root layer of the farmland soil shallow, causing degradation problems such as compaction and increased salinization, which seriously affect the yield and quality of potatoes.
