Yam rail-cultivating method

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

1. Technical field: [0001] The invention relates to a pollution-free and high-efficiency cultivation technology of Chinese yam. 2. Background technology [0002] Yam naturally grows about one meter underground. When planting, it is necessary to dig a 1-meter-deep soil layer. When harvesting, it is necessary to dig another 1-meter-deep soil layer and backfill it. The labor intensity is extremely heavy. Reducing the amount of labor and reducing labor intensity has always been a difficult problem for the majority of pharmaceutical farmers and scientific researchers. Although the technologies such as casing cultivation, hole cultivation, cellar cultivation and shallow pond hard bottom cultivation that have been promoted in recent years have reduced the workload and labor intensity to varying degrees, they still have their own insurmountable shortcomings. 1. The main disadvantages of casing cultivation are: large one-time investment, 26,000 yuan per mu of casing, difficulty in r...

AI Technical Summary

Problems solved by technology

Although the technologies such as casing cultivation, hole cultivation, cellar cultivation and shallow pond hard bottom cultivation that have been promoted in recent years have reduced the workload and labor intensity to varying degrees, they still have their own insurmountable shortcomings.

1. The main disadvantages of casing cultivation are: large one-time investment, 26,000 yuan per mu of casing, difficulty in reasonable dense planting, strict requirements for filling soil in the casing, and difficulty in accurately entering the casing, etc.

2. The main disadvantages of hole-piercing cultivation are: the cost of hole-piercing is high, and it is only cost-effective to drill a hole for several years, which is not conducive to crop rotation and stubble rotation. Only by crop rotation and stubble rotation can yam reduce pests and diseases, achieve stable and high yields, and improve the quality of yam tubers; only suitable It is not ideal to plant water yam varieties, but other types of varieties are not ideal; some soil quality cannot make holes; the problem of hole protection is complicated

3. The main disadvantages of kiln cultivation are: it takes a lot of labor and materials; it cannot be produced in a large area

4. The main disadvantages of hard-bottom cultivation in shallow ponds are: it is not conducive to drought irrigation and waterlogging, crop rotation and stubble, etc.
