Abstract

The invention discloses a corn and cowpea interplanting method including the steps of site preparation and fertilization, film covering and ridge forming, seed selection, seed processing, sowing, topdressing, vine guiding, and field management. The corn and cowpea interplanting method is characterized in that in the step of film covering and ridge forming, the ridge width is in the range of 20-25cm, the ridge interval width is in the range of 40-50cm, the ridge height is in the range of 5-8cm, and the ridge length is adjusted based on the length of the field; in the step of sowing, corns are sowed in the ridge in points in a single-row plantation manner, the distance between every two adjacent seed holes is in the range of 25-30cm, and the sowing depth is in the range of 3-5cm; and cowpeas are sowed at the positions 5-8cm away from the corns in a double-row staggering plantation manner. The interplanting method is advantageous in that nitrogen-fixing nodules at the roots of the cowpeas can enhance the absorption of crops to nitrogen, the corn stems can be supports for the cowpea vines to wind and can bear less pressure than sorghum stems, the cowpea harvesting or other operations have no influence to the growth of the corns, the cost is reduced, the economic benefit is improved, and the corn lodging caused by artificial factors can be prevented.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, in particular to a method for interplanting corn and cowpea. Background technique [0002] Cowpea is an annual twining herbaceous plant of Papilionaceae. There are three types of stems: dwarf, semi-climbing and trailing. The root system is well developed, and there are pink nodules on the roots that can fix nitrogen, which can strengthen the absorption of nitrogen. It has the growth habit of high temperature and heat resistance. Its suitable growth temperature is 20-25°C, but it can still set pods normally and do not drop flowers in a high temperature environment above 35°C; It cannot grow normally in the environment, and even the growth is inhibited. However, cowpea is a short-day crop, which does not have strict requirements on sunshine, and can be cultivated in spring, summer and autumn in the south. In addition, cowpea has wide adaptability to soil, as long as the drainage is good ...
