Method for cultivating shallots

Abstract

The invention relates to a cultivation method for shallot, relating to the vegetable cultivation technique. The shallot has the advantages of high output, high adaptability and high commodity value but has a plurality of defects on the cultivation technique, thus seriously affecting the harvest and quality. The invention controls an important planting part: selecting the shallots that are refrigerated to dormancy to plant and strictly controlling the process. The temperature is stabilized over three degrees and seeded on an ecological phytocidal mulching film, and a compound fertilizer with farmyard manure is adopted as a basic fertilizer. A first additional fertilizer is applied in the soil and a second additional fertilizer and a third additional fertilizer are sprayed on the leaf surfaces; water irrigation and fertilizing can be stopped half a month before harvest. The shallots can be harvested when the shallot leaves turn yellow at the end of September and at the beginning of October. The invention can lead a per Mu yield to be increased by 50 percent and has the advantages of high product quality, abundant vitamin and high commodity value.
