Method for directional tank shallow planting for Chinese yam

Abstract

The invention relates to a method for superficial cultivation of Chinese yam in directional grooves. The technical proposal includes: the line spacing of the ridge body wrapping ditch is L1=0.9-1.7m, the width of the excavation slope is L2=0.5-1.1m, and the slope of the slope is α=12-40 The height from the bottom of the slope to the ground is H1=13-38cm, the top of the slope rises from the ground and the height from the ground is H2=8-15cm; after spreading conventional base fertilizer on the slope, excavate along the slope according to the distance between plants of 20-25cm A small ditch matched with the directional groove, the small ditch is excavated along the slope direction, and then the directional groove is placed in the small ditch, and soft filler is placed in the directional groove; backfill the cultivated soil with a thickness of H3=5~15cm , and sorted into a ridge body with a side ditch, the width and depth of the side ditch are processed according to the routine; the potato seeds are planted above the upper end of the orientation groove 1-3 cm horizontally and 4-10 cm vertically from the upper end of the orientation groove. It has the advantages of being suitable for planting in various soils, convenient for harvesting, high yield, good quality, and good commodity properties, and is suitable for the cultivation and planting of various yams of the family Dioscoreae.

Description

technical field [0001] The invention belongs to the technical field of yam cultivation of Dioscoreaceae plant, and in particular relates to a shallow cultivation method of yam in a directional groove. Background technique [0002] Due to the gravitropism of yam tuber growth, traditional cultivation is planted in sandy soil with deep soil layer, low groundwater level, and convenient drainage and irrigation. In addition, the length of yam can reach one meter, and the tuber is crisp and tender, so harvesting is labor-intensive. Large, labor-intensive and time-consuming, it is also easy to damage the tubers, and its yield is also low, and its commodity properties are poor. It is not suitable for planting in hillsides and sticky, hard soils, which limits the scale production of yams. Contents of the invention [0003] The object of the present invention is to address the above problems and provide a shallow cultivation method for yams in directional grooves suitable for plantin...
