Embodiment 1

[0020] 1) Pit opening: 15 days before planting, ridges were formed on the planting site with a depth of 20 cm. After drying the soil for 5 days, the directional tunnels that allowed the Chinese yam to grow in a specific direction were tilted and buried at the bottom of the ridges;

[0021] 2) Back to the pit: After the directional tunnel is planted, carry out back to the pit and apply base fertilizer, the first layer of back soil is 5cm; the second layer of green manure is 5cm thick, and 0.5kg of lime is sprinkled on the green manure; Apply compound fertilizer on the fourth layer, 0.5kg per pit; apply farmyard manure on the fifth layer, with a thickness of 10cm; return soil to the sixth layer by 10cm;

[0022] 3) Planting: During the planting period, sow the yam seeds at a distance of 4cm from the ridge surface;

[0023] 4) Field management after planting includes water management, topdressing, vine trimming, flower bud wiping, weeding and pest control.

[0024] According to ...

Embodiment 2

[0026] 1) Pit opening: In mid-December, ridges were formed on the planting site with a depth of 30 cm. After drying the soil for 7 days, the U-shaped directional tunnels that allowed the Chinese yam to grow in a specific direction were buried obliquely at the bottom of the ridges;

[0027] 2) Back to the pit: After the directional tunnel is planted, carry out back to the pit and apply base fertilizer, the first layer of back soil is 7cm; the second layer of green manure is applied with a thickness of 8cm, and 0.8kg of lime is sprinkled on the green manure; Apply compound fertilizer on the fourth layer, 0.8kg per pit; apply farmyard manure on the fifth layer, with a thickness of 13cm; return soil on the sixth layer to 15cm;

[0028] 3) Planting: During the planting period, sow the yam seeds at a distance of 6cm from the ridge surface;

[0029] 4) Field management after planting includes water management, topdressing, vine trimming, flower bud wiping, weeding and pest control. ...

Embodiment 3

[0032] 1) Pit opening: 30 days before planting, ridges were formed on the planting site with a depth of 40 cm. After drying the soil for 10 days, the U-shaped directional tunnels that allowed the Chinese yam to grow in a specific direction were buried obliquely at the bottom of the ridges;

[0033] 2) Back pit: After the directional tunnel is planted, carry out back pit application of basal fertilizer, the first layer of back soil is 10cm; Apply compound fertilizer layer by layer, 1kg per pit; apply farmyard manure on the fifth layer, with a thickness of 15cm; return soil to the sixth layer by 20cm;

[0034] 3) Planting: During the planting period, sow the yam seeds at a distance of 8cm from the ridge surface;

[0035] 4) Field management after planting includes water management, topdressing, vine trimming, flower bud wiping, weeding and pest control.

[0036] According to the above-mentioned cultivation method (the field management after planting is the same), the income per...

Abstract

The invention discloses a high-yield cultivation method for yam. The method comprises the following steps of: (1) digging pits, i.e., ridging in a planting field with a depth of 20-40 cm 15-30 days before planting in winter, drying the soil for 5-10 days, and burying directional galleries, enabling yams to grow in a specific direction in ridge bottoms; (2) backfilling the pits, i.e., backfilling and applying basal fertilizer after the directional galleries are buried, backfilling soil of 5-10cm on a first layer, applying green manure of 5-10 cm on a second layer, backfilling soil of 2-5 cm on a third layer, applying compound fertilizer on a fourth layer for 0.5-1 kg every pit, applying farmyard manure of 10-15 cm on a fifth layer, and backfilling soil of 10-20 cm on a sixth layer; (3) planting, i.e., sowing yam seeds at places which are 4-8 cm away from the ridge surfaces in the planting period; and (4) performing field management after planting. The basal fertilizer is applied into the pits in advance, and the basal fertilizer on each layer infiltrates mutually to further compost, so that the growth soil of the yams is loose, the fertility is sufficient, the growth and the tuberization of the yam are facilitated, and a foundation is laid for high yield cultivation of the yams.

Description

technical field [0001] The invention relates to the planting technology of yam, in particular to a high-yield cultivation method of yam. Background technique [0002] Yam, also known as Chinese yam, contains starch and protein in its roots. It is used for both medicine and food. It has the effects of invigorating the spleen, helping digestion, tonifying deficiency and labor, and replenishing qi. It is an efficient economic crop. Huaishan is a perennial vine crop. Its growth requires loose soil and likes warm and humid conditions. The main producing areas in my country are Zhejiang, Fujian, Guangdong, Guizhou, Sichuan, Yunnan, Guangxi and so on. Most of the existing yam planting techniques adopt the traditional planting method: digging deep pits for cultivation, the cultivated yam tubers are uneven and the yield is low, which affects the income of farmers. People are working hard to study a kind of new cultivation method for this reason, to improve its yield. For example, ...
