Planting method for interplanting bitter gourds and sweet potatoes in greenhouse

Abstract

The invention discloses a planting method for interplanting bitter gourds and sweet potatoes in a greenhouse. The row distance of the bitter gourds is 1.2-1.3 m, and the sweet potatoes are interplanted between two rows of the bitter gourds. The method is capable of executing the strict control from various aspects, such as land selection and land preparation, germination of bitter gourd seeds, bitter gourd seedling culture, construction of a bitter gourd frame, field management, bitter gourd harvest, sweet potato planting, daily management of the sweet potatoes, and sweet potato harvest. The bitter gourds and the sweet potatoes are interplanted by using the different planting seasons and picking time of the bitter gourds and the sweet potatoes and the different growth spaces thereof. The land is rationally used, and the temperature and humidity regulation in the greenhouse is used, so the planting time of the bitter gourds and the sweet potatoes is shortened, and the seeding and harvesting seasons of the bitter gourds and the sweet potatoes are overlapped. The multi-harvesting per year can be realized, and the economic income of the greenhouse per unit area is improved.

Description

technical field [0001] The invention relates to the technical field of greenhouse planting, in particular to a method for planting bitter gourd interplanted with sweet potato in a greenhouse.
