Problems solved by technology

[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, and easy to damage 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.

Embodiment Construction

[0020] With reference to Fig. 1, the concrete steps of a kind of yam directional groove superficial cultivation method are:

[0021] 1), choose potato seeds: choose the thick and healthy potato pieces harvested in Xinyuan as potato seeds;

[0022] 2) Prepare the plastic directional groove: according to the length and size of the tubers of different varieties of yam, customize the plastic with a groove length of 50-110cm, groove depth of 1.8-4.5cm, groove arc length of 7-14cm, and groove arc curvature radius of 1.5-5cm. Orientation groove 1, the upper end of the groove is closed, the lower end of the groove is also closed, and three small holes with a diameter of 2 to 3 mm are arranged at the bottom of the groove;

[0023] 3) Site preparation and trough placement: build roads and drainage and irrigation systems in the garden, use 25kg of lime per mu, evenly sprinkle lime powder, and set the distance between rows of ridges and ditches to be L 1 =0.9~1.7m excavation slope 3, slo...

Abstract

The invention discloses a supergene cultivating method of directional groove of Dioscorea japonica, which is characterized by the following: the ridge groove distance L1 is 0. 9-1. 7m; the oblique excavating breadth L2 is 0. 5-1. 1m; the oblique slope alpha is 12-40 deg; the height between the bottom of slope and ground H1 is 13-38cm; the height between the top of slope and ground H2 is 8-15cm; the mated groove corresponding to the directional groove is excavated every 20-25cm along the slope; the directional groove is arranged in the groove with soft fill placing in the directional groove; the backfill thickness H3 is 5-15cm, which is trimmed into the ridge with groove; the breadth and depth is disposed normally; the potato is sowed at 1-3cm far away from the upper end of directional groove horizontally and 4-10cm far away from the upper end of directional groove vertically. The invention is convenient to harvest for kinds of soil, which is fit for cultivate Dioscoreaceae.

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...
