Embodiment Construction

[0019] The integrated planting method of potatoes with water and fertilizer in Yunnan in winter uses a tractor to pull and attach a seeder to complete the sowing work of ditching, ridging, sowing, fertilization, drip irrigation tape and plastic film covering at one time, including:

[0020] (1) Site selection and site preparation. Loam or sandy loam plots that require loose and fertile soil, deep soil layers, drainage and irrigation, and are required to be close to irrigation water sources, flat terrain, and less field obstacles are suitable. The sequence of soil preparation is: stubble cutting-plowing-rotary tillage, deep plowing up to 30cm or more, changing the previous mode of planting with manual and small tiller rotary tillage, ensuring loose soil, good air permeability, and improving water storage, water retention and fertilizer Ability, in standby state;

[0021] (2) Ditching and ridging, with a distance of 1.2 meters;

[0022] (3) Applying base fertilizer on the ridg...

Abstract

A water and fertilizer integrated planting method for potatoes in Yunnan in winter comprises the steps that a loam or sandy loam soil land parcel is selected, deeply ploughed by 30 cm or above, then furrowed and ridged, compound fertilizer special for potatoes is adopted and serves as bottom fertilizer applied to ridges, seeding is carried out on the ridges in a double-row planting mode, drip irrigation zones are laid on the ridges, the ridges are then mulched with plastic films, the films are covered with soil when potato seedlings grow to 2-3 cm away from the ridge surfaces, urea is applied in a drip irrigation mode for promoting growth of the seedlings when the potato seedlings grow to be 10 cm high, first time topdressing is carried out within one week after tubers are formed, topdressing is carried out along with moisture drip irrigation in the whole growing period, and eight times of topdressing is carried out in total.The method is capable of saving water, fertilizer and labor and efficient.

Description

technical field [0001] The invention belongs to the technical field of potato planting. Background technique [0002] The main winter potato planting areas in Yunnan Province are the southern hot areas and low-heat valley areas. This area is in the dry season of Yunnan Province in winter, and the water resources are extremely limited. Potatoes are one of the crops that require a large amount of water. Therefore, high-yield and efficient production It is closely related to the efficient use of water and fertilizer. Faced with the challenges of lack of water resources in winter in Yunnan and the efficient use of water and fertilizers, the current application of comprehensive supporting technologies for efficient use of water and fertilizers in potato production is weak, and irrigation and fertilization cannot be done reasonably according to the water and fertilizer requirements of potato growth. Water and fertilizer cannot be truly combined, resulting in water and fertilizer ...
