A potato-arrowhead pea intercropping method under the control of water and fertilizer to ensure stable yield and high quality of potatoes while fertilizing the soil

Abstract

The invention discloses a potato-arrowhead pea intercropping method under the control of water and fertilizer to ensure stable yield and high quality of potatoes while fertilizing the soil. This includes the following steps: (1) in the middle and late April of each year, two rows of high ridges are used for planting, two rows of potatoes are planted on the ridge, compound fertilizer is applied, arrowhead peas are planted in the furrow, nitrogen fertilizer is applied in the green manure row, and drip irrigation belts are laid; (2) ) Irrigate in mid-June; (3) Irrigate in late June; (4) Crush arrowhead peas during the full flowering period, overturn them on the ridge, and decompose; (5) Irrigate in mid-August; (6) Irrigate in early September . The invention can not only ensure the potato yield and improve the quality of the potatoes, but also improve the soil fertility and realize the goals of "replacing large fertilizers with small fertilizers" and "restoring while producing". Through the implementation of this model, efficient and sustainable potato production in Inner Mongolia 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.
