Technical Field
The invention relates to the technical field of crop planting, in particular to a method for improving drought resistance, freezing resistance and barren resistance of passion fruits.
Background
The passion fruit is also called passion fruit, is suitable for being planted in a region with a climate of 20-28 ℃ and is afraid of cold frost. At present, the Menghai county in Yunnan province is suitable for planting, but the situation of freezing still occurs under the condition of low air temperature in winter, the whole plant can die in severe places, and huge economic loss is caused for growers. Not only is the plant re-growth needed in the coming year, but the planting experience also shows that the yield and planting benefit of passion fruits are seriously affected in the second and third years after planting, so that most passion fruits are harvested only in the first year and cannot enter the yield-increasing period in cold winter.
The Chinese patent of application number 201910775710.4 discloses a passion fruit overwintering method, which uses the alkaline action of plant ash and the heat preservation action of soil to make the interior of passion fruit seedlings not freeze in cold winter by spraying stucco slurry composed of plant ash and soil on main vines, so that the internal structure of passion fruit seedlings is not damaged by ice crystals, and the vitality is preserved, thereby smoothly passing through cold winter and providing conditions for high yield in the coming year.
Through practice, the anti-freezing capacity of the passion fruit is not improved to a higher degree by adopting the method, and more death of the passion fruit plant still can be caused.
