Cost-saving and yield-increasing culture technique for southern winter potato

Abstract

The invention belongs to the technical field of culture of potato, and particularly discloses a cost-saving and yield-increasing culture technique for southern winter planting potato. The technique comprises the following steps of: selecting a land, preparing the land and furrowing; applying a base fertilizer; treating potato seeds; seeding; covering with soil; covering with a film; earthing up the film; managing liquid manure, weeds and insect pests; and harvesting, wherein a method of earthing up the film is that: a layer of smashed soil of 5-8 centimeters is covered on the film by using a machine or a hoe, so that the film on a ridge surface is covered fully. In the technique, an integral water manure furrow application method is used innovatively, so that the labor per acre is saved by 7 persons, and the acre yield is up to 9,136 jin. Due to the adoption of the technique, the increase in of the yield of potato is facilitated, the production cost is lowered, and the economic benefit of potato production is increased. On the aspect of technique, the process flow of potato production is completed, the production time of potato is shortened, and a solid technical foundation is laid for the popularizing scale, standardization and commercial production of the potato industry.

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. Due to the low temperature and less rainfall in winter, planting potatoes in winter has strict requirements on all aspects of planting techno...
