Embodiment 1

[0033] The test site is located in Xishagou Village, Keke Town, Ulan County, Qinghai Province, with a demonstration area of ​​2,000 mu. The potato variety to be tested is "Xiaboti".

[0034] A potato water and fertilizer integrated drip irrigation cultivation method. It includes the following steps in turn: site selection, site preparation, seed selection, seed potato treatment, ridge mulching and sowing, basal fertilizer application, integrated drip irrigation and fertilization of water and fertilizer, and field management; among them,

[0035] First of all, choose a land with no obvious slope and gentle terrain; when preparing the land, the whole field should be operated, and the root stubble should not be kept. Before planting, the soil should be rotated to a depth of 25cm, and the root stubble and rubbish should be broken. The soil should be flat and fine. Reach the state of ready-to-sow; select high-quality virus-free seed potatoes that meet the standards of the potato Xi...

Abstract

The invention relates to the technical field of cultivation of potatoes, in particular to a water and fertilizer integration drip irrigation cultivation method of potatoes. The method comprises the specific steps of land selection, land preparation, seed selection, treatment of seed potatoes, base fertilizer application, ridging, film covering and seeding, water and fertilizer integration drip irrigation fertilization, field management and the like. The water and fertilizer integration drip irrigation cultivation method of the potatoes has the advantages that the water-saving percentage of irrigation reaches 47.37-49.35%; in the normal mode, a nitrogenous fertilizer is improved by 16.61-19.35%, a phosphatic fertilizer is improved by 5.15-6.19%, and a potash fertilizer is improved by 20.37-26.25%; the utilization ratio of cultivated lands is improved by 5.5-7.5%; the labor productivity cost is saved by 23.53-41.17%; the pesticide dosage can be saved by 10-23%; the yield is improved by 14.75-52%, and the comprehensive economic benefits per mu is improved by 9.37-45.97%.

Description

technical field [0001] The invention relates to the technical field of potato cultivation, in particular to a potato water and fertilizer integrated drip irrigation cultivation method. Background technique [0002] At present, due to the influence of factors such as backward irrigation methods and technologies and low utilization rate of water resources, the phenomenon of agricultural water shortage is very serious. Putting water safety on the agenda, the Qaidam Basin is a typical high-altitude oasis irrigated agricultural area in my country. Due to the local drought, little rain, strong sunshine, and large evaporation, water is the lifeline for the development of agriculture, forestry and animal husbandry in the basin. For a long time, the phenomenon of flood irrigation in agricultural production in Qaidam irrigation area has been very common, which makes the problem of the utilization of limited irrigation water resources more prominent. [0003] With the adjustment of th...
