Problems solved by technology

[0002] At present, in the high-temperature and arid areas of my country, such as the Hetao area around the Alashan Desert in Inner Mongolia, the Chifeng area in Inner Mongolia, Gansu Province, Shaanxi Province and Xinjiang Province, the potato planting areas are high-temperature, dry and less rainy. The existing potato cultivation technology cannot simultaneously achieve high and stable potato yields and Rational use of water in parallel, how to improve the efficiency of potato use of natural rainfall and soil moisture, enhance the ability of potato drought resistance, so that potatoes can obtain high yield is an urgent problem to be solved
[0003] At present, in high-temperature and arid areas, the high-yield and water-saving cultivation methods for potatoes in high-temperature and arid areas are as follows: potato seeds are sown 8-10 cm away from the ground level, the ridge height after intertillage is 20 cm, the ridge surface width is 35-45 cm, and the ridge width is 35-45 cm. It is 55-45 centimeters, and the depth of furrow is 30-35 centimeters, and the pit operation is not carried out. The disadvantages of the above-mentioned cultivation methods are that the water use efficiency and yield are low.

Embodiment 1

[0030] A high-yield and water-saving cultivation method for potatoes in high-temperature and dry areas, the method is used for cultivating common potatoes, comprising the following steps:

[0031] 1) Land selection and land preparation: select a plot that has not been planted with Solanaceae crops within three years, turn the land and rotary tillage, the depth of the tillage is 35-40cm, and apply 50 kg of compound fertilizer per mu of land before rotary tillage, preferably Yes, the composition of the compound fertilizer is N:P 2 o 5 :K 2 O=12:18:15.

[0032] 2) Seed potato treatment: select basic seed potatoes with consistent seed potato grades. The size of the basic seed potato is 50-130 grams, and the seed potato is placed in the warehouse under the condition of scattered light, and the seed potato will germinate in about 7 days. After the seed potatoes come out of the cellar, carefully sort them, pick out the diseased and irregular seed potatoes, and cut the healthy and...

Embodiment 2

[0065] A high-yield and water-saving cultivation method for potatoes in high-temperature and arid areas, suitable for deserts where the daily average temperature is ≥10°C, the accumulated temperature is above 2500°C, the annual rainfall is less than 250 mm, the annual average evaporation is above 2000 mm, and the crop growth period is dry and rainless In marginal irrigated agricultural areas, the method for cultivating early-maturing varieties of potatoes includes the following steps:

[0066] 1) Land selection and land preparation: select a plot that has not been planted with Solanaceae crops within three years, the depth of plowing is 40cm, and 50 kg of compound fertilizer is applied to each mu of land; the composition of the compound fertilizer is N:P 2 o 5 :K 2 O=12:18:15.

[0067] 2) Sowing and Ridging: Sowing: Potato planting row spacing is 90cm, seed potato planting distance is 12-13cm from ground level, sowing density is 3500 plants / mu; 20cm. Make pits in the ditch...

Abstract

This application provides a high-yield and water-saving cultivation method for potatoes in high-temperature and arid areas, which is suitable for irrigated agricultural areas on the edge of deserts where the accumulated temperature is above 2500°C, the annual rainfall is less than 250 mm, and the annual average evaporation is above 2000 mm. , the application adopts the method of planting in low ridges and adding ridges and ditches to make pits, comprising the following steps: soil preparation; sowing: seed potato sowing is 12-13cm away from the ground level, the row spacing of seed potatoes is 90cm, and the sowing density is 3500-4000 plants / mu; Ridge: The height of the ridge is 20cm, the width of the ridge surface is 55cm, and the width of the furrow is 35cm. The pits are drilled in the furrows. The pits are continuous inverted wedges, the depth of the pits is 20cm, and the widest part of the pit is 60cm. Field management; harvesting . The cultivation method makes water use rationally, increases potato yield, and improves water production efficiency.
