Chinese yam high-yield and orientation cultivation method

Abstract

The invention mainly discloses a Chinese yam high-yield and orientation cultivation method. According to Chinese yam growth characteristics and expansion growth characteristics of yam underground tubers, U-shaped groove supergene orientation cultivation is implemented, a series of improved cultivation techniques of early-stage preparation, timely planting, field management, timely harvesting and the like are implemented, seed nature degeneration is relieved, original high-yield biological natures of Chinese yams are furthest kept, the Chinese yams rapidly and strongly grow, planting density can be increased, the planting quantity per mu can reach 1500 plants, the yield per mu can reach 3000 kilograms, and the method has the advantages of high yield, less disease, simplicity and conveniencein harvesting and the like. By the method, holes cannot be deeply dug when the Chinese yams are planted, the Chinese yams are planted in pre-buried U-shaped supergene orientation grooves, the Chineseyams are harvested by the aid of simple tools, operation is simple, production cost is reduced, and the yield is high. According to the method, water is rapidly discharged, moisture can be preserved,planting and harvesting are facilitated, planting efficiency is improved, the nutrition quality of Chinese yam products is high, and planting economic benefits are remarkable.

Description

[0001] Technical field

[0002] The invention relates to a yam planting and production technology, which belongs to the field of famous, special and high-quality agricultural production and cultivation technology, and specifically relates to a high-yield directional cultivation method of yam.

[0003] technical background

[0004] Huaishan, Chinese name: Yam.

[0005] Other names: Chinese yam, Chinese yam, Chinese yam, native potato, yam, sweet potato, wild potato, white yam, etc.

[0006] Huaishan belongs to Dioscoreaceae and Dioscorea genus, and belongs to twining herbaceous vines. The tubers are long cylindrical, grow vertically, and can reach more than 1 meter in length. Most of the cross-sections are white when dry, and a small part is also purple.

[0007] Huai Yam likes high temperature and dryness. The tubers start to germinate at 10°C. The suitable temperature for stem and leaf growth is 25-28°C. The suitable ground temperature for tuber growth is 20-24°C. It grows i...

Examples

Embodiment approach

[0063] (1) Preliminary preparation

[0064] (1) Seedlings: select the stem and tail of Yam yam long column as the seedlings, and the potato pieces have been germinated through germination treatment;

[0065] (2) Orientation trough: U-shaped directional shallow trough with a length of 1.5 meters made of plastic material;

[0066] (3) Fertilizer preparation: Use pig manure, cow horse manure or sheep manure. The fertilizer should be dried and finely crushed, and then fermented with calcium and phosphate fertilizer for about 15 days to make it fully fermented and decomposed;

[0067] (4) Land selection: choose fertile soil, deep sandy loam and easy-to-drain plots as planting sites, and can also be planted in high plots with clay and groundwater levels;

[0068] (5) Soil preparation: According to the general method of soil preparation, the depth of plowing is 40 cm, and after finely crushed and leveled, it is prepared to be cultivated according to a width of 100 cm. ;
