Embodiment 1

[0025] 1. Variety selection: Select new potato varieties with high quality, high yield and strong disease resistance that are suitable for local planting. Late-maturing varieties are selected in the range of 1800-2000m above sea level; medium-maturing varieties are selected in the range of 2000-2300m above sea level; early-maturing varieties are selected in the range of 2300-2700m above sea level.

[0026] 2. Seed potato treatment technology: On the premise of using virus-free seed potatoes, the seed potatoes are strictly selected 15-20 days before sowing. After the seed potatoes are sun-dried to accelerate germination before sowing, cut into pieces according to the bud eyes, and eliminate diseased potatoes when cutting into pieces. Soak the cutting knife with 0.1% potassium permanganate solution for 5-10 minutes when cutting into pieces to disinfect. For every 130-150kg cutting, use 300g powder of seed dressing agent (potato seed dressing agent purchased from Gansu Academy o...

Embodiment 2

[0035] Embodiment 2: the fertilization process in step 5 among the embodiment 1 is as follows: potato belongs to the high fertilizer-requiring crop, and every 1000kg potato is produced, nitrogen application 4.4kg, phosphorus pentoxide 1.8kg, potassium oxide 7.9kg, three ratios are 1 :0.4:2. The base fertilizer is mainly farmyard manure and chemical fertilizer. Generally, 2 cubic meters of high-quality farmyard manure is used per mu, and the amount of chemical fertilizers accounts for 2 / 3 of the total fertilizer amount, which can be applied by rotary tillage before sowing. Potassium dihydrogen phosphate can be sprayed on the leaves of the plots with weak seedlings after flowering. Topdressing is carried out during the potato expansion period, accounting for 1 / 3 of the chemical fertilizer application.

Embodiment 3

[0036] Embodiment 3: the fertilization process in step 5 in embodiment 1 is as follows: potato belongs to the crop that needs fertilizer highly, and every 1000kg potato is produced, nitrogen application 5.5kg, phosphorus pentoxide 2.2kg, potassium oxide 10.2kg, three ratios are 1 :0.4:2. The base fertilizer is mainly farmyard manure and chemical fertilizer. Generally, 4 cubic meters of high-quality farmyard manure is used per mu, and the amount of chemical fertilizers accounts for 2 / 3 of the total fertilizer amount, which can be applied by rotary tillage before sowing. Potassium dihydrogen phosphate can be sprayed on the leaves of the plots with weak seedlings after flowering. Topdressing is carried out during the potato expansion period, accounting for 1 / 3 of the chemical fertilizer application.

Abstract

The invention discloses a layered tuberization potato cultivation method characterized by micro-ridging film laminating, repeated earthing-up and high yield, and aims at solving the problems of low yield, high green potato rate and poor commodity in existing potato production. The method comprises the following steps of A, seeding potatoes at appropriate time, wherein the potatoes are seeded in the first ten-day period of April of a normal year in a region of which the altitude is below 1,800m according to the regional climate characteristics, are appropriately seeded in the last ten-day period of the April in a region of which the altitude is 1,800-2,300m, and are appropriately seeded in the first ten-day period and the middle ten-day period of May in a region of which the altitude is above 2,300m; performing scribing according to 1.1m in the seeding process, trenching two sides of a middle line, and performing two-line seeding, wherein the line spacing is 25-30cm, the row spacing is 22-25cm, and bud eyes face upwards; performing micro-ridging film laminating cultivation in the seeding process, wherein the height of each ridge is 5-8cm; B, performing repeated earthing-up and layered tuberization. The method has the advantages that by virtue of the repeated earthing-up, tuberization over a film and tuberization below the film can be realized, exposure of stolon is prevented, the top end of the stolon is urged to be expanded in soil to form a tuber, two to three additional potatoes can be obtained for a single plant, the green potato rate is remarkably reduced, and the large potato rate and the commodity are obviously improved.

Description

technical field [0001] The invention relates to a method for cultivating potatoes. Background technique [0002] At present, most of the sowing methods used in potato production are: after ditching and on-demand sowing, a ridge with a height of 25-30cm is raised at one time, and then covered with film (or not covered with film) or after a ridge with a height of 25-30cm is raised at one time, and then used "Spot planting gun" is used for sowing, so that the depth of the sowing method can reach 10cm-15cm, and the cultivation of high ridges in production is one-time molding without soil cultivation, resulting in slow emergence, poor uniformity, serious lack of seedlings and broken ridges; To achieve multiple soil cultivation, the rate of green potatoes is high, the commerciality is poor, the utilization rate of fertilizers is low, and the occurrence of diseases and insect pests is serious, which affects the expansion of tubers. Contents of the invention [0003] The object o...
