Embodiment 1

[0036] 1. Seed selection and germination

[0037] 1) Select the healthy potato pieces harvested in Xinyuan as potato seeds, cut into pieces, each piece is about 40 grams, dip the incisions in lime or plant ash, stack them separately according to the head, middle, tail and size, and plant them in a centralized manner when planting. It is conducive to the balanced and coordinated growth of yam.

[0038] 2) Accelerate the germination before planting. Rinse with clean water and soak in 25% carbendazim wettable powder 800 times for 10 minutes, take it out and dry it for later use. For germination, spread the potato pieces to a thickness of 15 cm indoors and cover with wet straw. Or outdoors, on the shoveled furrow surface, spread it with a thickness of 10 cm, cover with fine soil 5-10 cm, and then cover with wet straw, and transplant it when bud eyes grow.

[0039] 3) When planting, only one strong bud is left, and the rest are removed.

[0040] 2. Prepare the half casing for cul...

Embodiment 2

[0065] 1. Preparation before planting

[0066] 1) Choose a place. Choose a sandy loam plot with deep, fertile soil and a groundwater level below 1 meter to cultivate yams.

[0067] 2) Choose the right variety. Choose long cylindrical yam varieties with high yield and disease resistance, excellent shape and epidermal characteristics, and the tuber length is required to be more than 1 meter. Commonly used varieties are fine-haired long yam, Huai yam, Huilou yam and so on.

[0068] 3) Process the plastic casing. Thinner plastic is used to process the groove length from 100 to 110 cm, the groove depth from 1.8 to 4.5 cm, the groove arc length from 7 to 14 cm, and the groove arc curvature radius of

[0069] 4) 1.5-5 cm plastic groove, the upper end of the orientation groove is closed, the lower end is open, and several small holes are arranged at the bottom of the groove.

[0070] 5) Put the casing on the ground. The soil requirements for shallow casing cultivation are not ve...

Embodiment 3

[0090] A kind of half casing cultivation method for Chinese yam, it is characterized in that comprising the following steps:

[0091] 1) Select a sandy loam block with a groundwater level below 1m; take a half-sleeve made of plastic material with a length of 100cm, a groove depth of 1.8cm, and a groove arc length of 7cm; Embedded in the sandy loam block at an inclination angle of 12° from the horizontal, with the arc facing down; take silt, mix it with wood chaff or chaff in a weight ratio of 80:15, and put it into the half set In the tube, cover with 2cm sand layer; apply organic fertilizer;

[0092] 2) Take yam, cut into pieces with a weight of 35g each, dip the section in lime or plant ash, and then dry it in the sun for 2 days; The block is sown in the 2cm sandy soil layer described in step 1) with the angle of the bud eye upward;

[0093] 3) Cultivate until the aboveground stems and leaves of the yam are dead and harvested.

[0094] On the basis of the above technical ...

Abstract

The invention provides a half-pipe culture method for yams. The technical scheme comprises the following steps: based on collecting Jiangxi yam resources, analyzing a plurality of common half-pipe culture techniques systematically, applying an orthogonal experiment technique to screen out proper culture density and a fertilizing method, and constructing a yam half-pipe culture technique system suitable for the agricultural ecological condition of the province; and the half-pipe culture method fills the gap of local variety half-pipe culture techniques of Jiangxi yams. By comparing the used half-pipe culture techniques with the traditional yam culture techniques, the harvest area of each laborer can rise to 0.3 mu from 0.03 mu each day, thereby saving 30 laborers each mu; the mu yield increases by 470 to 900 kilograms, and the increasing rate is 16 to 45%; and the produced yam chips are orderly, full, smooth and good in skin color, no damage is generated during excavation, the tubers can be stored for a long time and the value of commodity is high, so that the half-pipe culture method for the yams is worth large-area popularization.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, and further relates to a large-scale cultivation method of Chinese yam, in particular to a half-pipe cultivation method for Chinese yam. Background technique [0002] Yam is the tuber of a vine belonging to the genus Dioscorea spp. of the family Dioscoreaceae. Its flesh is thick and slightly cylindrical. In my country, except for the northern part of the northeast and the Northwest Loess Plateau, it is cultivated in other places, especially in Shandong, Henan, Jiangsu, Fujian, Taiwan, Guangdong, Guangxi and Sichuan, and the resources are very rich. [0003] Studies in recent years have shown that yam not only contains general components such as carbohydrates, crude protein, dietary fiber, crude fat, vitamins, mineral nutrition, and free amino acids, but also contains phenolic substances, mucus, choline, allantoin, and yam. Pre-saponins, sterol saponins, soluble polysaccharides, phytic a...
