High-yield culture technology for southern potatoes planted in autumn

Abstract

The invention belongs to the technical field of potato culture, in particular to a culture technology for southern potatoes planted in autumn. The culture technology comprises the following steps of: selecting a land, preparing and ridging; applying base fertilizers; cutting potato seeds, immediately sterilizing, accelerating germination and air-drying within one hour; finishing sowing at the temperature of earth surface of 15-25DEG C at noon on the second day after seed cutting; after sowing, immediately spraying water; carrying out management on water, fertilizer and diseases, insect pests and weeds; and harvesting. According to the culture technology disclosed by the invention, the emergence rate of the potatoes planted in autumn reaches over 90 percent and the situation that the yieldof the potatoes in southern part is reduced by over 60 percent due to frost and the potatoes are not suitable for being planted in autumn is changed; meanwhile, if the potatoes are planted before andafter Mid-Autumn Festival, the potatoes can appear on the market before Spring Festival and two months earlier compared with the potatoes planted in winter; in addition, the market price of the potatoes is 0.2-0.3yuan per jin, thereby the economic benefit of the potatoes planted in autumn is increased.

Description

technical field [0001] The invention belongs to the technical field of potato cultivation. Background technique [0002] potato( Solanurn tuberosum L. ) is an economic crop of Solanaceae Solanaceae. Potatoes are high-yield crops that are used as food, vegetables, and feed. Because the tubers contain more nutrients such as starch, vitamins, and lysine, they are an excellent food with multiple characteristics of grains, vegetables, and fruits. Nutritional value, known as "perfect" food by domestic and foreign nutritionists, known as "underground apple" and "second bread" of human beings, is the most important food in many countries in the world. [0003] my country is a large potato producing country, and the total potato production ranks first in the world. my country has rich practical experience in potato cultivation technology. [0004] In the south, especially in northern Guangdong, there are frosts around the winter solstice every year, and the frost can reduce the ...

AI Technical Summary

Problems solved by technology

[0004] In the south, especially in northern Guangdong, there are frosts around the winter solstice every year, and the frost can reduce the potato yield by more than 60%. In order to avoid the frost, the only choice is to sow 100 days before the frost and harvest before the frost comes. Autumn planting potatoes Planting, but the sowing season happens to be the high-temperature season (July-September). Over the years, potato rotten seeds often appear when planting potatoes in high-temperature seasons. No specific reason for the rotten seeds, just want to treat the seeds with medicine to prevent rotten seeds

Therefore, the potato emergence rate has become the bottleneck of the southern potato autumn planting cultivation technology
