Abstract

The invention relates to a winter-late-autumn-potato early-marketed planting method, and belongs to the field of planting. The method includes the steps of selecting a potato variety, accelerating germination of potato seeds, coating the potato seeds, determining the sowing date, preparing soil, early applying N-and-P base fertilizers, sowing ridging potato seed with buds, covering a film, erecting small sheds on ridges, controlling overgrowth to promote tuber expansion and controlling potato epidemic diseases. According to the winter-late-autumn-potato early-marketed planting method, early seedling emergence and early potato forming are effectively promoted, the large potato rate of tubers is increased, the defect that as a N fertilizer is applied after potatoes are sowed, potato formingis delayed is overcome, the problems that the large potato rate is low, hollow heart and brown patch disease are easy to occur are solved, epidemic disease is controlled through a leaf fertilizer anda trichoderma-strain biological bacterium agent, and the mode is a green, ecological and no-residue control measure. Potatoes are early marketed, and the aims of increasing production and increasing income are effectively achieved; the method is a planting technology that winter-late-autumn potatoes early enter fresh vegetable markets of outer country in extremely-deficient season, and meanwhile it can be promoted that the income of potato farmers is increased, and the winter-late-autumn-potato early-marketed planting method is suitable for application and popularization in the lower and middle elevations of the southwest.

Description

technical field [0001] The invention relates to a potato planting method, in particular to a potato planting method for promoting morning market in winter and spring, and belongs to the field of planting. Background technique [0002] Potato industry in winter and spring has become a pillar industry in the planting industry of Yunnan Province, and it is one of the main sources of income for farmers at middle and low altitudes in winter. Since the sowing season in winter and spring is from November to January, and the emergence of seedlings is from December to February, they are extremely susceptible to frost, which makes the potato industry unstable and a fatal blow. Cultivation in protected areas can effectively prevent frost and promote early emergence and early expansion of tubers. It is an important link in the production of field potatoes to promote early market production. [0003] N fertilizer is one of the elements with the highest nutrient requirement in potatoes. ...
