Problems solved by technology

However, in the prior art, when the sweet potato is cultivated, the direct ridge covering cultivation is often adopted, and the film is then watered, and the water is replenished into the ridge through lateral infiltration, but this requires multiple watering, which is easy to cause waste of water, and the water Inhomogeneous replenishment, causing adverse effects on potato shape

Embodiment 1

[0035] In 2017, sweet potato was cultivated in Hanzhuang Village, Xiongxian County, Hebei Province, and the sweet potato variety used was Jishu 26.

[0036] In January 2017, the field was plowed to a depth of 25cm and left to dry. On April 20, 2017, the field after drying will be 50m 3 Amount of water per mu, airing 5d after watering, on April 26 in the field, apply soil miscellaneous fertilizer (amount of application is 900Kg / mu) and ternary compound fertilizer (the mass ratio of nitrogen, phosphorus and potassium is 10:10 :20, the application rate is 55Kg / mu), after fertilization, press the ridge distance 80cm, and the ridge height is 32cm to form a ridge. Potato seedlings (the potato seedlings were first pulled out from the seedbed on April 25, and the potato seedlings were soaked with 450 times of carbendazim at the base of 6 cm for 20 min) were planted on the ridge at 40° to the horizontal plane (the planting depth was 7 cm, Leave the top 3 unfolded leaves in the aboveg...

[0038] In 2017, sweet potato was cultivated in Hanzhuang Village, Xiongxian County, Hebei Province, and the sweet potato variety used was Jishu 26.

[0039] In January 2017, the field was plowed to a depth of 30cm and left to dry. On April 20, 2017, the field after drying will be 40m 3 Amount of water per mu, airing 7d after watering, in April 28th, apply soil miscellaneous fertilizer (amount of application is 1100Kg / mu) and ternary compound fertilizer (the mass ratio of nitrogen, phosphorus and potassium is 10:10) :20, the application rate is 45Kg / mu), and after fertilization, the ridges are ridden by 90cm of ridge spacing and 28cm of ridge height. Plant the potato seedlings (on April 27th, choose 27cm potato seedlings, first pull out the potato seedlings from the seedbed, soak the 10cm part of the base of the potato seedlings with 400 times of carbendazim for 10 minutes) and plant them in the ridge at an angle of 50° to the horizontal plane Above (the planting depth is 5 ...

Embodiment 3

[0041] In 2017, sweet potato was cultivated in Hanzhuang Village, Xiongxian County, Hebei Province, and the sweet potato variety used was Jishu 26.

[0042] In January 2017, the field was plowed to a depth of 28cm and left to dry. On April 20, 2017, the field after drying will be 45m 3 Watering in the amount of water per mu, airing for 6 days after watering, applying soil miscellaneous fertilizers (amount of application is 1000Kg / mu) and ternary compound fertilizer (the mass ratio of nitrogen, phosphorus and potassium is 10:10) in the field on April 27 :20, the application rate is 50Kg / mu), after fertilization, press the ridge distance 85cm, and the ridge height is 30cm to form a ridge. Potato seedlings (on April 26th, choose 25cm potato seedlings, first pull out the potato seedlings from the seedbed, soak the 8 cm part of the base of the potato seedlings with 600 times thiophanate-methyl for 15 minutes) and plant them at an angle of 45° to the horizontal plane. On the ridge...

Abstract

The invention provides a water-saving cultivation method for sweet potatoes, and belongs to the technical field of agricultural production. The cultivation method comprises the following steps 1) after winter comes, ploughing soil and airing the upturned soil; 2) in five to seven days before planting sweet potato seedlings, first performing moisture preservation, fertilization and ridging on the upturned soil that is aired; 3) planting the sweet potato seedlings on ridges at an angle of 40-50 DEG with a horizontal plane, the planting depth being 5-7 cm, leaving three expanded leaves of an overground part on the top, and burying all the rest part together with leaves in oil, the overall sweet potato seedlings being in the shape of a boat; and 4) after planting the sweet potato seedlings, covering with a mulching film, putting the sweet potato seedlings out of the film, and covering with soil to seal film mouths around the sweet potato seedlings. By adopting the method provided by the invention to cultivate sweet potatoes, the yield per mu is above 5000 Kg, is improved by above 1500 Kg compared with the comparative example 1, and the commodity rate is improved by about 15%.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and in particular relates to a water-saving cultivation method of sweet potatoes. Background technique [0002] Sweet potato (Ipomoea batatas L.) is an important food and feed crop in the world, as well as an important industrial raw material and new energy material. Sweet potato has high yield, stable yield and strong adaptability. According to the statistics of the World Food and Agriculture Organization, in 2016, the planting area of ​​sweet potato in my country was 49.22 million mu, with a total output of 70.57 million tons, ranking first in the world. However, in the prior art, when the sweet potato is cultivated, the direct ridge covering cultivation is often adopted, and the film is then watered, and the water is replenished into the ridge through lateral infiltration, but this requires multiple watering, which is easy to cause waste of water, and the water Inhomogeneous r...
