Problems solved by technology

[0005] 1. The amount of rice straw required is relatively large. More than 1,300 kilograms of rice straw is needed per mu of potatoes (that is, 3 acres of rice straw is needed to plant 1 mu of potatoes), and the development in straw-scarce areas and multi-purpose areas of rice straw is limited; the amount of rice straw The large size also brings adverse consequences of declining economic benefits. Calculated at 0.3 yuan per kilogram of straw, the production input of enterprises or large planting households will increase by nearly 500 yuan per mu, which is very unfavorable for the development of potato production.
[0006] 2. The emergence of seedlings is slow and irregular, and the management of seedlings is more difficult. If the grass cover is too thick, it will not be conducive to the emergence of seedlings. If it is too thin, the water will evaporate easily, causing the seed potatoes to lose water.
[0008] 4. In the no-tillage planting mode of rice straw, the fertilizer is applied on the upper part of the rice straw in the middle and later stages, the fertilizer is not easy to infiltrate, the fertilizer utilization rate is low, the fertilizer efficiency is poor in the later stage of potato production, and the rice straw is not fully decomposed, and the utilization rate of rice straw dissolved fertilizer is not high.
[0009] 5. Due to the insufficient decomposition of straw, it will increase the difficulty of land preparation and rice planting in the next stubble paddy field
[0010] 6. Prone to rodent damage
Mice in the field have less food in winter and will build nests in the lower layer of straw and gnaw on the seed potatoes, seriously affecting the emergence of seedlings

Embodiment 1

[0041] A cold- and drought-resistant potato cultivation method includes the following steps:

[0042] (1) Variety selection: select high-quality, high-yield, wide adaptability, strong disease resistance, good commercial properties, and fresh-eat early-maturing virus-free potato varieties;

[0043] (2) Seed potato treatment: 8 days before planting; 30g small piece of seed potato whole potato is sown, soaked and sterilized with 500-700 times solution of polydraxis for 20 minutes; seed potato above 50g is cut into pieces, and prepare two cuts The knives are all immersed in 1% potassium permanganate solution for disinfection and used in rotation. Each seed potato 35g, with 1 to 2 bud eyes, the cut potato chunks are cut and mixed with seed dressing disinfectant powder; The raw materials of the seed dressing disinfectant powder are proportioned by weight: 1000 g of double fly powder, 20 g of 5% thiophanate methyl, 20 g of polydrzone, and 1 g of neophytomycin, and the above raw materials ...

Embodiment 2

[0052] A cold- and drought-resistant potato cultivation method includes the following steps:

[0053] (1) Variety selection: select high-quality, high-yield, wide adaptability, strong disease resistance, good commercial properties, and fresh-eat early-maturing virus-free potato varieties;

[0054] (2) Seed potato treatment: 5 days before planting; 40g small piece of seed potato whole potato is sown, soaked and disinfected with 500-700 times solution of polydrichosis for 15min; more than 50g seed potato is cut into pieces, prepare two cuts The knives are all immersed in 1% potassium permanganate solution for disinfection, and they are used in rotation. Each seed potato is 25g, with 1-2 bud eyes. The cut potato pieces are cut and mixed with seed dressing disinfectant powder; The raw materials of the seed dressing disinfectant powder are proportioned by weight: 1000 g of double fly powder, 20 g of 5% thiophanate methyl, 20 g of polydrzone, and 1 g of neophytomycin, and the above raw m...

Embodiment 3

[0063] A cold- and drought-resistant potato cultivation method includes the following steps:

[0064] (1) Variety selection: select high-quality, high-yield, wide adaptability, strong disease resistance, good commercial properties, and fresh-eat early-maturing virus-free potato varieties;

[0065] (2) Seed potato treatment: 50g small pieces of seed potatoes are sown, soaked and disinfected with 500-700 times solution of polybrechium for 15 minutes; seed potatoes above 50g are cut into pieces, and two cutting knives are soaked in 1% Disinfected in potassium permanganate solution and used in rotation, each seed potato 40g, with 1 to 2 bud eyes, the cut potato chunks are seed-dressed with seed dressing disinfectant powder; The raw materials of the seed dressing disinfectant powder are proportioned by weight: 1000g Shuangfei powder, 20g 5% Thiophanate methyl, 20g Polydactyx and 1g neophytomycin. The above raw materials are mixed evenly and mixed with 100kg seed potatoes and cut into pi...

Abstract

The invention discloses a cold-proof drought-resistant cultivation method for potatoes, and relates to the technical field of potato cultivation. The cultivation method comprises the following steps: selecting varieties, processing potato seeds, preparing soil and ridging, sowing and applying a fertilizer, laying a trickle irrigation pipeline and watering, laminating a film and covering soil, taking cold-proof measures, preventing and controlling plant diseases and insect pests, harvesting and grading. Compared with a normal no-tillage cultivation and straw covering cultivation technology, the cold-proof drought-resistant cultivation method for potatoes disclosed by the invention does not need to use straws for planting the potatoes, so that the production raw materials and the artificial operation cost are reduced, the cold-proof drought-resistant effects are good, and high-quality products are produced. Moreover, a green potato rate and morbidity are obviously reduced, the goods potato rate of the potatoes and the yield are increased, so that the economic benefits are remarkable.

Description

Technical field [0001] The invention relates to the technical field of potato cultivation, in particular to an efficient potato cultivation method with high yield and high quality, reduced green potato rate, cold and drought resistance, and in particular to a cold and drought resistant potato cultivation method. Background technique [0002] Potato is the fifth largest crop in my country, with an annual planting area of ​​70 million mu and an output of about 100 million tons. It has comprehensive nutrition and can be used as both food and vegetable. Since the harvest of winter potatoes in southern China is in the gap in the national market, the price is relatively high and the economic benefits are significant. It has become a dominant crop to increase farmers' income in winter. [0003] At present, the potato cultivation technology widely used in the southern winter cropping area is the rice straw mulching cultivation technology. This technology is the no-tillage rice straw mulch ...
