A high-yield and water-saving cultivation method for potatoes in high-temperature and dry areas

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.

Description

technical field [0001] The application relates to the technical field of crop planting, in particular to a high-yield and water-saving cultivation method for potatoes in high-temperature and dry areas. Background technique [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 techniques cannot simultaneously achieve high and stable potato yields and How to improve the utilization efficiency of natural rainfall and soil moisture, enhance the drought resistance ability of potato, and obtain high yield of potato are the problems that need to be solved urgently. [0003] At present, in high-temperature and arid areas, the high-yield and water-saving cultivation methods for potatoes in high-temperature an...

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.
