Embodiment 1

[0022] Example 1 Taking the planting of fine leaves deep (name of Chinese yam variety) as an example, the description is as follows:

[0023] Planted in sandy soil, the planting time is 5 days after the solar term "Small Heat", and the harvest time starts after New Year's Day of the following year. By May, compared with the traditional yam cultivation technology, the yield per mu has increased by 450 kg, and the yam fries produced are neat and consistent. , uniform and plump, smooth, beautiful skin color, less mechanical damage to the potato pieces, high commodity rate and high commodity value; the specific method is:

[0024] (1) Soil preparation and ditching: After the land preparation, each furrow will cover a ditch with a width of 1.5m and a ditch depth of 20cm, which will be excavated with a small hoe to a U-shaped inclined ditch with a width of 8cm, a slope of 15°, and a height difference of 25cm between the upper and lower ends; After the ditch is dug, the bottom of the...

Embodiment 2

[0029] Example 2 Taking the planting of Dayeshen (the name of the Huaishan variety) as an example, the description is as follows:

[0030] Planted on clay soil in rice fields, the planting time is 10 days after the solar term "Small Heat", and the harvesting time starts after New Year's Day of the following year. By May, compared with the traditional yam cultivation technology, the yield per mu has increased by 550 kg, and the yam chips produced Neat and consistent, uniform and plump, smooth, beautiful skin color, less mechanical damage to potato pieces, high commodity rate and high commodity value; the specific method is:

[0031] (1) Soil preparation and ditching: After the land preparation, each furrow will include a ditch with a width of 1.1m and a ditch depth of 15cm, excavated with a small hoe to a U-shaped inclined ditch with a width of 6cm, a slope of 10°, and a height difference of 28cm between the upper and lower ends; After the ditch is dug, the bottom of the ditch ...

[0036] Example 3 Taking the planting of Dayeshen (the name of the Huaishan variety) as an example, the description is as follows:

[0037] Planted on clay soil in rice fields, the planting time is 8 days before the solar term "Great Heat", and the harvest time starts after New Year's Day of the following year. By May, compared with the traditional yam cultivation technology, the yield per mu has increased by 400 kg, and the yam chips produced Neat and consistent, uniform and plump, smooth, beautiful skin color, less mechanical damage to potato pieces, high commodity rate and high commodity value; the specific method is:

[0038] (1) Soil preparation and ditching: After the land preparation, each furrow is covered with a ditch 2m wide and 30cm deep, which is a U-shaped inclined ditch with a width of 10cm excavated by a small hoe, a slope of 20°, and a height difference of 30cm between the upper and lower ends; the inclined ditch After digging, tamp the bottom of the ditch with ...

Abstract

The invention discloses a cultivation method of Chinese yam using shallow directional PVC boards. The method includes: preparing a field, digging parallel inclined channels on the prepared field, placing the pre-cut shallow directional PVC boards into the inclined channels, filling the inclined channels with filler, leveling the field, and performing fertilizer application and management. The method has the advantages that the advantages such as high day-night temperature difference of shallow soil, looseness and fertility of the soil, adequacy of nutrients and good ventilation are utilized, the PVC boards are used to design U-shaped plastic troughs suitable for the cultivation of Chinese yam, the Chinese yam is allowed to grow and tuberize close to the surface at a certain inclined angle, the factors hindering large-area development of Chinese yam, such as suitable soil type and terrain limitations, high harvesting intensity, difficult in operation of tubers and influence on storage can be overcome, and the production condition that the traditional cultivation is time consuming, labor consuming, low in yield and low in efficiency is changed. The cultivation method has the advantages of wide range of suitable lands, high tuberization speed and ease of harvesting; high-yield efficient cultivation of high-quality Chinese yam is achieved.

Description

technical field [0001] The invention relates to a method for cultivating Chinese yam, in particular to a method for cultivating superficial yam with directional PVC boards, and belongs to the technical field of crop cultivation. Background technique [0002] Huaishan, also known as yam, is the dried rhizome of Dioscorea opposita Thunb., a plant of the Dioscorea family. It is sweet in taste and flat in nature, and enters the lung, spleen, and kidney channels; Essence, clear ears and eyesight, help the five internal organs, strengthen the muscles and bones, long-term calm the nerves, and prolong life; it is mainly used to treat weak spleen and stomach, fatigue and weakness, loss of appetite, chronic diarrhea, dryness of lung qi, phlegm asthma and cough, kidney qi deficiency, waist Knee soreness, weakness of lower limbs, thirst, frequent urination, nocturnal emission, premature ejaculation, cloudy leukorrhea, red and swollen skin, obesity and other diseases. Fresh yam is a dai...
