Embodiment 1

[0012] Oriented tuber cultivation of Chinese yam in hilly and mountainous areas:

[0013] According to the climatic conditions in Guangxi, sow seeds from mid-May to early June. Ridging is performed at a row spacing of 150-160 cm. A plastic film with a thickness of 5 c is laid on the soil layer at a depth of 15 cm from the slope of the planting bed. The slope is 45° to the horizontal plane. ; Yam seeds are sown in the soil about 4cm above the hard material on the top of the ridge, the distance between the plants is 20-22cm, and 2223 plants are planted per mu; the amount of fertilizer applied per mu: 2000kg of sugarcane filter mud, 30 catties of compound fertilizer as base fertilizer, applied on July 16 15kg of urea and 15kg of potassium fertilizer, and 45kg of compound fertilizer was applied on September 12; when the tuber period was dry, the sprinkler irrigation system was used to spray water. The yield was measured on December 23. The high-yield plots had an average potato weig...

Embodiment 2

[0015] Oriented tuber cultivation of Chinese yam in dry land:

[0016] According to the climatic conditions in Guangxi, the soil should be prepared on April 20, and the seeds should be sown from May 15 to June 2. The row spacing should be 150-160 cm, and a plastic film with a thickness of 5 c should be laid on the soil layer at a depth of 10 cm from the slope of the planting row. , its slope is 25° to the horizontal plane, and the yam seeds are sown in the soil about 8cm above the hard material on the top of the ridge. 15 kg of compound fertilizer was used as the base fertilizer, 15 kg of urea and 15 kg of potash fertilizer were applied on July 16, 45 kg of compound fertilizer was applied on September 12, and horse racing water was irrigated during drought. The yield was measured on December 19. The average potato weight per plant was 1.82kg, the largest single potato weight was 4.2kg, the tubers were smooth and well-proportioned, the commodity rate was over 96%, and the fresh...

Abstract

Disclosed is a method for cultivating directional fructification yam which comprises ridge forming, laying the bottoms of the soil with plastic foil or other hard material at a depth 10-15cm from the inclined surface of the ridge, sowing the seeds of Chinese wam into soil 4-10cm above the hard material in the ridge top, so as to make the Chinese wam tuber grow directionally along the material. The cultivation method can substantially improve both the single yield of Chinese wam and quality.

Description

technical background [0001] The traditional cultivation of Huai Yam is to choose sandy soil with deep soil, fertile soil and good drainage conditions as the planting site. When preparing the site, dig a planting ditch with a row spacing of 100 cm, a width of 100 cm, and a depth of 100 cm. The excavated soil is placed on both sides of the ditch. side, to make the soil weathered, before planting, fill the ditch with the original soil into the ditch, and when it is filled to 2 / 3 of the ditch, apply 3,000 catties of retting farmyard manure per mu, and mix the fertilizer with the soil filled back into the ditch. Mix well to improve the soil layer structure in the ditch, then fill the ditch with soil, start a furrow, open a small ditch with a width of 10 cm and a depth of 10 cm on the furrow surface, make a 100 cm deep hole at a distance of 20 cm, and fill the hole with fine Sand, put the yam seedlings flat on the hole, and align the bud eyes of the seedlings with the hole so that the ...
