Fresh-eaten broad bean and corn interplanting method

Abstract

The invention discloses a fresh-eaten broad bean and corn interplanting method. Broad bean and corn are planted at intervals in a strip-shaped alternating mode, broad bean are planted in strips in the planting period of broad bean, the planting period of broad bean is earlier than that of corn, broad bean is planted before corn, and the space for planting corn in strips is reserved when broad bean is planted until corn is planted in strips in the planting period of corn; 2-3 rows of broad bean are planted in each broad bean strip, 2 rows of corn are planted in each corn strip, the row distance of broad bean and corn is reasonably arranged, broad bean rows and corn rows do not affect mutually, and the ventilating and light transmitting effects are better. The distance between the broad bean strips and the corn strips is 50-67 cm, after corn is planted, the corn strips and the broad bean strips are not adjacent, and enough space is reserved for transmitting light instead. The production period of broad bean and that of corn are different, by reasonably arranging the row distance, crop groups can enjoy light receiving environment, disease damage is reduced, and therefore the crop yield is increased.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, and further relates to a method for interplanting fresh broad beans and corn. Background technique [0002] Broad bean is a leguminous crop that can be used as both grain and vegetable, combining land use and cultivation. The grains of fresh broad bean are rich in protein, fat, minerals and multivitamins. It is a vegetable delicacy and an important spring crop. As one of the most important food crops in my country, corn is also the food crop with the highest yield in the world. It is the crop with the largest area and yield potential among dryland food crops. It is widely planted in northern and southwestern hills of China. [0003] The traditional method of planting broad beans is to plant all broad beans on the entire land, which has poor ventilation and light transmittance, and the light transmittance is less than 30% during the flowering period. It is easy to form a small damp ...

AI Technical Summary

Problems solved by technology

However, when traditional broad beans are intercropped with corn, due to the lack of reasonable field configuration, single-row alternate planting is used, which is not conducive to light transmission and ventilation, and is also not conducive to personnel harvesting and mechanized management, resulting in low production efficiency.
