Hibicus sabdariffa and pinellia ternate intercropping method

Abstract

The invention discloses a hibicus sabdariffa and pinellia ternate intercropping method. The hibicus sabdariffa and pinellia ternate intercropping method comprises the following steps: selecting land with sandy loam, and performing disinfection, plowing, fertilization and furrowing to obtain a furrow surface; digging planting rows on the furrow surface according to the row spacing of 8-10cm, the line spacing of 12-16cm and the depth of 3-5cm, planting one pinellia ternata seed tuber in each hole, covering soil to keep the planting surface flush, and watering the planting surface with bottom water; digging planting holes in the west side of the furrow surface according to the plant spacing of 80 cm to 100 cm, the line spacing of 80 cm to 100 cm and the depth of 6 cm to 8 cm, wherein one hibicus sabdariffa seedling is planted in each hole, and bottom water is poured; performing water management, fertilization management and pest control on hibicus sabdariffa and pinellia ternate; performing pinching when hibicus sabdariffa blooms to a preset proportion, harvesting once every 5-7 days, and intensively harvesting pinellia ternata after seedlings fall. According to the method, the land utilization area can be increased, the output of unit area land is increased, illumination is fully utilized, the two are mutually supplemented in the farm management process, repeated application of fertilizer and pesticide is reduced, and the soil and ecological environment can be protected.

Description

technical field [0001] The invention belongs to the technical field of crop planting, in particular to a method for intercropping roselle and pinellia. Background technique [0002] Roselle (Hibicus sabdariffa L.), also known as Roselle, is native to Sudan in Africa and is widely distributed in tropical and subtropical regions of the world. Epicalyx rose red. Roselle is a natural nutraceutical plant with both medicinal and edible value. The calyx, seeds, stems, and leaves of the plant can be used, and the dry and fresh products of the calyx are the most valuable. Roselle fresh calyx contains vitamin C0.93%, vitamin B0.21%, protein 0.45%, pectin 1.39%, carrot 0.01%, dried calyx contains total anthocyanin (pigment) 1.5%, citric acid, hibiscus acid 10- 15%, reducing sugar 16%, protein 3.5-7.9%, fiber 11%, and 1% of 17 amino acids. Roselle calyx processed products taste sweet and sour, diuretic, promote bile secretion, reduce blood viscosity, lower blood pressure and stimulat...

AI Technical Summary

Problems solved by technology

[0004] At present, the planting method of roselle is that only one kind of crop is planted in one field; and Pinellia is mostly planted in plain areas with artificial shade or half-shade and half-sun on gentle slopes; The land use efficiency is low, especially the Tai Pinellia is too affected by natural conditions, which wastes land resources and manpower and material resources, and the economic benefits are low.
