Embodiment Construction

[0018] The present invention will be further described below in conjunction with embodiment, but can not be regarded as limitation of the present invention.

[0019] A kind of drip irrigation planting method of potato, comprises the steps:

[0020] (1) Seed selection and seed treatment

[0021] Select virus-free varieties with high-yield and excellent varieties. The selected seed potatoes are placed in a room with scattered light conditions, germinated at 12-15°C, and cut into pieces when the buds are 1-1.5cm long. When cutting seed potatoes, use 75% Alcohol or 0.5% potassium permanganate disinfectant for disinfection, to ensure that there are 1-2 bud eyes on each potato piece, and the weight of the potato piece is not less than 30g.

[0022] (2) Site selection and preparation

[0023] Choose weakly acidic light loam or sandy soil with flat terrain, deep soil, loose soil, good permeability, rich organic matter content, close to water sources, convenient drainage and irrigati...

Abstract

The invention provides a potato drip irrigation planting method comprising seed selection, seed treatment, land selection, land preparation, sowing, drip irrigation tape laying, field management, and irrigation system determination. The irrigation system is that in years with normal rainfall, when soil water content is lower than 65% of a field maximum water holding capacity, sowing water irrigation is carried out once, wherein the amount of irrigation water is 20m<3>/mu; drip irrigation is carried out 1-2 times during a potato tuber formation stage and 2-3 times during a swelling stage, wherein the amount of irrigation water is 20m<3>/mu each time and the total amount of irrigation water is 60-100m<3>/mu. According to the invention, the potato drip irrigation method is used in northern areas; a potato and summer corn double-cropping system is used for replacing a winter wheat and summer corn double-cropping planting system with high water consumption, such that high yield and water saving effects are achieved, and economic benefit and water resource utilization are greatly improved.

Description

technical field [0001] The invention relates to a drip irrigation planting method, in particular to a drip irrigation planting method of potatoes. Background technique [0002] Water resources in the North China Plain are in short supply, with the total amount accounting for only 7.6% of the national total, and the per capita is only 1 / 5 of the national total. The traditional double-cropping system of winter wheat and summer corn a year, because winter wheat consumes a lot of agricultural water, the water saving effect after the introduction of drip irrigation technology in this area is not obvious, and the economic benefits of this traditional mode are not high, which directly leads to the grain loss in this area. The contradiction between supply and demand of production water is prominent. Therefore, seeking a new water-saving planting system to replace the high water-consuming planting system of double cropping of wheat and jade has become one of the agricultural technol...
