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 an early potato water-saving irrigation technology. In the whole growth period, the watering quantity is controlled to be 110 m<3> / mu; segmented watering is performed; concretely, 16.5 m<3> / mu of watering is performed at 50-percent seedling emergence; 22 m<3> / mu of watering is performed at 50-percent squaring of plants; 27.5 m<3> / mu of watering is performed when plants start to bloom; 27.5 m<3> / mu of watering is performed when 50-percent plants bloom; 16.5 m<3> / mu of watering is performed when 50-percent plants are out of bloom; reasonable and proper-quantity irrigationis performed according to the growth characteristics and water requiring conditions of early potatoes in each period; the irrigation process is improved; the irrigation frequency is controlled, so that the irrigation water has the maximum utilization rate, and the conformance to the points of the growth period is realized; and under other normal conditions of management, the per mu yield of the early potatoes is not reduced. Compared with that of ordinary furrow irrigation watering, the water consumption reduction per mu can reach 30 percent or higher.

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...
