Abstract

The invention relates to the field of planting, in particular to a cultivation method of kidney-shaped Chinese yam. The method includes the steps of 1, spreading a breathable backing which limits growth of the Chinese yam, in made ditches, spreading farmyard manure on the backing, and spreading crushed straw; 2, earthing the crushed straw; 3, planting the Chinese yam on each ditch. The Chinese yam cultivated by the method is kidney shaped, is large and solid, has yellow and smooth skin and white and fine pulp, is both loose and floury, has no pucker taste and is long in shelf life, high in price, crush resistant and tolerant to storage and transportation; the yam grown in the loose fertilizer-straw layer is convenient to dig; the yam is convenient to plant and harvest; labor intensity is low, and the yam rarely breaks and is convenient to store and transport.

Description

The cultivation method of kidney shape Chinese yam

Technical field

The present invention relates to plant cover cultivation methods field, i.e. the cultivation method of kidney shape Chinese yam.

Background technology

In the prior art, Chinese yam be Chinese yam ( dioscorea oppositathunb.) stem tuber, elongated cylindrical, vertical-growth, can reach more than 1 meter.Need excavation to be the planting furrow of 80 ~ 150cm deeply during plantation, still need during results to deep-cut and be more careful in case dig wound and dig disconnected.Therefore, traditional planting patterns labour intensity of Chinese yam is large, time-consuming, take a lot of work, require great effort, fragilely to fracture.Also there is bibliographical information Chinese yam cultivation method, but be all and cultivate bar-shaped Chinese yam.

Summary of the invention

The object of the invention is the cultivation method that a kind of " kidney shape " Chinese yam is provided for above-mentioned deficiency, be intended to solve Chinese yam cultivation, receipts difficulty and potato block and easily hinder easily broken problem.

Technical solution of the present invention is: the cultivation method of kidney shape Chinese yam, and its step is as follows:

(1) in the furrow dug, paving restriction Chinese yam grows and the wall to wall of breathing freely, and at wall to wall upper berth farmyard manure, repaves the stalk of pulverizing.

(2) blinding on stalk.

(3) plant by spacing in the rows field planting Chinese yam kind above every bar planting furrow.Wall to wall is ventilative gauze pad, plastic knitting bag webs preferably or nylon gauze.

Preferred: the cultivation method of kidney shape Chinese yam, its step is as follows:

(1) select plot on the sunny side, turn over and harrowed 55 ~ 65 large ridges of cm, from plot, the first furrow begins to shovel out bottom of trench soil, makes it to be 25 ~ 30cm " U " shape groove deeply.Stone rubble in ditch can be removed by " U " shape ditch, and has enough garden loams to cover in excrement-grass layer; Be conducive to the profile that Chinese yam forms lower flat upper circle; Can fill more farmyard manure and stalk in groove makes Chinese yam have sufficient enlarged void.

(2) spreading wide is the plastic knitting bag webs of 40 ~ 50cm, at the thick farmyard manure become thoroughly decomposed of plastic knitting bag webs upper berth 5-6cm, repaves the crops straw that 10 ~ 15cm pulverizes.

(3) with the garden loam in next furrow fill out lid its upper to flat ditch (thickness of soil is for 10 ~ 15cm), what cleaning made new advances simultaneously waits to arrange groove, processes successively, every two arrangement ditches are a frame group, every ditch.

(4) plant by spacing in the rows 25 ~ 30cm field planting Chinese yam kind, mu plants 3500 ~ 4000 strains.Other culture technique link is with traditional cultivation.

When Chinese yam kind stem grows to wall to wall downwards, because plastic knitting bag webs toughness is strong, hinder it to continue growth downwards, when stem tuber expands, in loose fertile capim gordura layer, form loose " kidney shape " stem tuber.Kidney shape Chinese yam shape as kidney-shaped, but is not limited thereto, and mainly refers to non-clavate, is block, oblateness.

Advantage of the present invention is: 1, the present invention plants the Chinese yam potato block profile that obtains as kidney, and loose solid, Beijing opera is smooth, meat white fine and smooth, not only husky but also face, puckery without raw meat, storage endurance, price are high, not easily fragmentation, storage tolerance.2, Polywoven Bag is made into by warp and parallel, with monolayer plastic braiding bag webs place mat, can guarantee water-permeable and air permeable.Use waste or used plastics woven bag to realize twice laid, reduce production cost low, and place mat method is easy.3, the growth of potato block is in loose fertilizer-grass layer, is convenient to excavate.4, kidney shape Chinese yam cultivation, Shou Fangbian; Labour intensity is low; Potato block is not easily hindered disconnected, is convenient to deposit, transport.

Below in conjunction with embodiment, embodiments of the present invention are described in further detail.

Embodiment

Embodiment 1

The cultivation method of kidney shape Chinese yam, it is suddenly as follows: select plot on the sunny side, turn over after the health of cleaning rural area and harrowed the large ridge of 60cm, from one side, plot, the first furrow begins to shovel out bottom of trench soil, make it to be 25 ~ 30cm " U " shape groove deeply, pick stone in groove, the hard object such as rubble, paving individual layer wide be about 40cm waste or used plastics weave bag webs, bag webs first spreads the thick farmyard manure become thoroughly decomposed of 5cm, repave the crops straw that 10 ~ 15cm pulverizes, fill out with the garden loam in next furrow again and cover on it to flat ditch, what cleaning made new advances simultaneously waits to arrange groove, process in accordance with the law, every two arrangement ditches are a frame group, every ditch the like.Plant by spacing in the rows 25 ~ 30cm field planting Chinese yam kind, mu plants 3500 ~ 4000 strains.Other culture technique links are with traditional cultivation.Each Chinese yam weight is at average about 0.5 kilogram.

Embodiment 2

The cultivation method of kidney shape Chinese yam, its step is as follows:

(1) select plot on the sunny side, turn over and harrowed the large ridge of 60cm, from plot, the first furrow begins to shovel out bottom of trench soil, and making it to be dark is 25cm " U " shape groove.

(2) spread the wide plastic knitting bag webs for 40cm, at the thick farmyard manure become thoroughly decomposed of plastic knitting bag webs upper berth 5cm, repave the crops straw that 10cm pulverizes.

(3) it is upper to flat ditch to fill out lid with the garden loam in next furrow, and what cleaning made new advances simultaneously waits to arrange groove, processes successively, and every two arrangement ditches are a frame group, every ditch the like.

(4) plant by spacing in the rows 33cm field planting Chinese yam kind, mu plants 3600 strains etc.

Describe above, just the specific embodiment of the present invention, various illustrating is not construed as limiting flesh and blood of the present invention.
