Embodiment Construction

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0029] The experiment was carried out at the experimental base of Shijiazhuang Academy of Agriculture and Forestry Sciences in Zhao County from March to July 2019. The moisture content of the potatoes before sowing was consistent, and there was no difference in field fertilization and pest control.

[0030] A total of 6 water treatments (Table 1) were set up in the experiment, with a single-factor randomized block design and 3 repetitions. Furrow irrigation was used for the co...

Abstract

The invention discloses a water-saving irrigation technology for early-maturing potatoes, and the watering amount in the whole growth period is controlled at 110m 3 / Mu, watering in sections, specifically watering 16.5m when 50% of the seedlings emerge 3 / mu; water 22m when the plants are budding 50% 3 / mu; water 27.5m when the plants start to bloom 3 / mu; water 27.5m when 50% of the plants bloom 3 / mu; water 16.5m when 50% of the plants fall 3 / mu; According to the growth characteristics and water demand of early-maturing potatoes in each period, carry out reasonable and appropriate irrigation, and improve the irrigation process, control the irrigation frequency, so that the irrigation water has the maximum utilization rate and meets the point of the growth period. In other normal management conditions Under this condition, the per-mu yield of early-maturing potatoes will not decrease, and the water saving per mu can reach more than 30% compared with ordinary furrow irrigation.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a water-saving irrigation technology for early-maturing potatoes. Background technique [0002] Global agriculture in the 21st century faces two major challenges: one is the need to increase food production to meet population growth, and the other is the need to deal with the dwindling water resources while increasing food production. Potatoes are favored and valued by the world for their high yield and high efficiency, wide adaptability, complete and rich nutritional components, and long industrial chain. In recent years, China's potato planting area has also shown a rising trend, and it is the country with the largest potato planting area in the world. [0003] However, with the growth of population, the development of towns and industries, the change of global climate and the aggravation of environmental pollution, water resources for crop irrigation are becomin...
