Method for planting rivier giantarum rhizome through ditching, film laying and ridging

Abstract

The invention discloses a method for planting rivier giantarum rhizomes through ditching, film laying and ridging. The method achieves fertilizer conservation, heat preservation, disease resistance, high yield and convenient digging. The method comprises the specific steps that 50-300 g of rivier giantarum rhizomes are selected as seed rivier giantarum rhizomes; ditches with the width of 0.8-1.2 m and the depth of 20-30 cm are dug, and black microhole mulching films are laid on the bottoms of the ditches; farmyard manure is laid on the black microhole mulching films and covered with soil with the thickness of 2-5 cm; the seed rivier giantarum rhizomes are placed on the soil layer according to the certain row spacing and line spacing, and then earthing and ridging are carried out, wherein the height of ridges is 20-40 cm; the ridge faces are covered with grass with the thickness of 2-5 cm; 1000-1500 jin of farmyard manure is applied to each mu of land. A row of corn can be planted on the sides of the ridges. The fertilizer efficiency can be sufficiently utilized, the production cost is reduced, it is ensured that the rivier giantarum rhizomes are dug conveniently and rapidly, and the digging cost can be saved by 400-500 yuan for per mu.

Description

technical field [0001] The invention relates to a method for planting konjac by ditching pad film and ridges, and belongs to the technical field of agricultural production. Background technique [0002] Konjac, also known as konjac, konjac, pedicel lotus, snake corn, snakehead grass, etc., is a perennial herb of the genus Konjac in the Araceae family. It is a special economic crop containing a large amount of glucomannan in nature. Materials and other aspects are widely used, and it is a new fashion to use it to produce health food and functional food. In recent years, with the increasing demand for konjac and its processed products in domestic and foreign markets, the market has shown a situation of short supply, making the konjac industry a sunrise industry in the 21st century. [0003] Konjac mostly grows in alpine and semi-alpine areas, mostly on slopes, and mechanized operations are difficult. Konjac is basically excavated manually with tools such as hoes and shovels. ...

Problems solved by technology

[0003] Konjac mostly grows in alpine and semi-alpine areas, mostly on slopes, and mechanized operations are difficult. Konjac is basically excavated manually with tools such as hoes and shovels. Generally, one person can only dig 200-250 catties of konjac a day. The labor efficiency is low and the intensity is low. Large size, high breakage rate, and poor commerciality; and the existing planting mode adopts the fertilization method of "planting and fertilizing" to put the taro into the sowing ditch, place the taro and cover it with a layer of 2-3 inch thick thin Soil, and then apply farmyard manure to separate the seed fertilizers; this planting mode uses 2000-3000 catties of farmyard manure per mu. During the production process of konjac, the fertilizer efficiency is seriously lost. Only by topdressing can the growth of konjac be satisfied need
