Abstract

The invention discloses an orbit culturing method of a yarn. At first, two pieces of cloth with different widths are used for manufacturing the growing orbit of the yarns; the wide piece of cloth is arranged in the lower place and the narrow piece of cloth is arranged in the upper place; the bottoms are also aligned and overlapped; and a plurality of lines are sewed on the oblique transverse direction in parallel. The pulled length of the narrow piece of cloth is larger than the diameter of the yarn when each line is sewed. Then soil and furrow preparation is carried out; secondary, orbit paving, soil covering and planting are carried out; and after the seed is grown, an agricultural machine is used for removing the covered soil, and then the yarn is artificially harvested. In the invention, geometrical principle is used for scientifically manufacturing the tuber of the yarn and paving the orbit so as to change the vertically downward growing habit of the yarn for the convenience of mechanized farming and harvesting and ensure the yarn to grow in the orbit and achieve the goals of reducing work and saving the cost and increasing the yield. The method is suitable for large area culturing.

Description

The rail-cultivating method of Chinese yam

One, technical field:

The present invention relates to a kind of Chinese yam Nuisanceless high-efficient culture technique.

Two, background technology

The Chinese yam self-sow will excavate 1 meter dark soil layer during kind about next rice of ground, the time receiving will be excavated 1 meter dark soil layer again, also wants backfill, and labour intensity is very heavy.Reduce the amount of labour and reduce labour intensity, be numerous medicinal herb growers of puzzlement and scientific research personnel's a difficult problem always.Technology such as the sleeve pipe cultivation of Tui Guanging in recent years, holing cultivating, the cultivation of cellar for storing things formula and the cultivation of the hard end of the shallow pool though all reduced workload in various degree, have reduced labour intensity, but still have had the shortcoming that himself can't overcome.1, the major defect of sleeve pipe cultivation has: one-time investment is big, and every mu of sleeve pipe need be invested 26000 yuan, and the rational close planting difficulty is big, and banketing in the sleeve pipe requires sternly, and stem tuber accurately enters sleeve pipe difficulty etc.2, the major defect of holing cultivating has: the cost height that burrows, and it is just worthwhile with several years to make a call to a hole, be unfavorable for crop rotation, and Chinese yam has only crop rotation could reduce damage by disease and insect, realizes high and stable yields, improves the quality of Chinese yam stem tuber; Suitable planting water Chinese yam veriety only, and it is very undesirable to cultivate other type kind; The soil property that has can not burrow; Protect hole problem complexity.3, the major defect of kiln formula cultivation has: the expense of taking a lot of work material; Can not large tracts of land production.4, the major defect of the hard end, shallow pool cultivation has: be unfavorable for that drought waters waterlogging row, crop rotation etc.

Three, summary of the invention

Utilize geometrical principle, make for the stem tuber science of Chinese yam, lay track, change the habit that it is grown vertically downward, receive, be allowed to condition in the track and grow, reduce work, save the purpose of cost and high yield, good harvest to reach for making things convenient for the mechanization kind.

Technical scheme of the present invention is: at first make Chinese yam growth track with two blocks of different clothes of width, wide cloth is following, and narrow cloth is last, the base alignment is overlapping, many lines of oblique parallel sewing, sewing thread becomes certain included angle with the base, when sewing every sewing thread with narrow cloth horizontal drawing number centimetre.The angle on every sewing thread and base is between 20-45 °.Distance between each sewing thread is 10-25 centimetre.The length of narrow cloth horizontal drawing is 3-11 centimetre when sewing every sewing thread.Narrow cloth lacks 5-15 centimetre than wide cloth width, and their length is not limit.Second step was to do furrow wholely: per 3 lines are one group, are divided into cultivation area, borrow areas, with agricultural machinery the furrow that the cross section is an isosceles trapezoid are made in the cultivation area.The base angle in cross section of whole furrow between 40-60 °, between top width 40-70 centimetre, height is between 20-80 centimetre.The 3rd step was to lay track, earthing, sowing: wide cloth is following, track laterally is laid on the inclined-plane of cultivation area, insert a small amount of soil in each track upper end during sowing, with Chinese yam kind piece kind at wide cloth than narrow cloth on the wide part that goes out, the soil in borrow areas is covered in raceway surface afterwards again and forms overburden layer, overburden layer thickness is more than the 20cm.The 4th step was results: wait to grow up to the back and remove earthing with agricultural machinery, manually gather.

The invention has the beneficial effects as follows: compare with existing other culture techniques and have 1, realized that the mechanization kind receives, reduced labour intensity, reduced workload.2, reduced one-time investment, and once investment, to be benefited for many years, every mu of track is under-capitalized 1000 yuan, can use more than 5 years.3, to soil and yam variety no requirement (NR).4, every year can both crop rotation, and labor and material saving, suitable commerial growing.5, because of guaranteeing rational close planting, and satisfied the physiological property (as: optimum temperature that the good gas of root system is water funk, stem tuber is grown underground 20-50 centimetre soil layer) of Chinese yam, output obviously improves.6, improved the quality of product.Because the stem tuber of Chinese yam is grown in track, therefore smooth straight, deformity is few, and damage by disease and insect is light, and commodity is good.

Five, embodiment

At first to determine to cultivate the kind of Chinese yam, understand length, diameter and suitable spacing in the rows, the line-spacing of stem tuber.

1, making the cloth of track should be nontoxic, flexible, corrosion-resistant, waterproof, retractility is little, the cloth that valency is low, select press mold polypropylene woven cloth for use for one section, shown in the accompanying drawing 1: with two blocks of clothes of width, the width of wide cloth (1) is at 20-100 centimetre, wide cloth (1) material is following, narrow cloth (2) material is last, the both sides alignment is overlapping, wide cloth (1) is than the wide about 5-15 of narrow cloth (2) centimetre, oblique parallel sewing many sewing threads (3) then, the angle on sewing thread (3) and cloth base is that the distance between each sewing thread (3) is about 10-25 centimetre between 20 °-45 °.With narrow cloth horizontal drawing certain-length, its length is 1.5 times of diameter of yam variety, between 3-11 centimetre when sewing every sewing thread (3).The length of wide cloth (1) and narrow cloth (2) is not limit.

2, do furrow wholely: the cross section structure of one group of furrow shown in the accompanying drawing 2, furrow are cultivation area (4) in the middle of every group of 3 furrow, the both sides furrow are borrow areas (5), cultivation area (4) generally is made into isosceles trapezoid, its base angle is between 40-60 °, and between top width 40-70 centimetre, the furrow height is between 20-80 centimetres.Cultivation plot preferably drought can be watered, and waterlogging can be arranged, more than the subterranean water level 50cm.

3, lay track, earthing, sowing: the inclined-plane that track laterally is laid on cultivation area (4), when being close to inclined-plane, sowing, wide cloth (1) inserts a small amount of soil every track upper end, again with Chinese yam kind piece kind at wide cloth than narrow cloth on the wide part that goes out, soil with borrow areas (5) is covered in raceway surface formation overburden layer afterwards, its soil thickness should be more than 20cm, and a track plantation Chinese yam is respectively laid on (4) two inclined-planes, cultivation area.

4, results: when treating that Chinese yam grows up to results, remove earthing, manually gather with agricultural machinery.
