A method for solving rose rhizomes becoming soft, small flowers and petals scorched under high temperature

Abstract

The invention provides a method for solving rootstock softening, flower smallness and petal edge scorching of roses under high temperature. Cut-flower rose plants are pruned according to time requirements on the regulation of flowering time; flower buds are sprayed with gibberellin solution at the mass concentration of 0.05-0.20%; pedicel is coated with honey solution at the mass concentration of 5-10%; based on previous treatments, the cut-flower roses can normally grow in a 25-35 DEG C high temperature environment. According to the method, as the physical habits of the cut-flower roses are adjusted by using gibberellin, the roses meeting cut-flower standards can still be produced in the high temperature environment; the sugar degree is improved by adding honey, so that the pedicel growth is accelerated.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, in particular to a planting method for planting cut roses. Background technique [0002] Roses like sunshine, are more cold-resistant, drought-tolerant, like ventilated and cool climate, and the suitable growth temperature is 15-25 degrees. Roses have strong adaptability and are not strict on the soil. They grow well in fertile neutral or slightly acidic light loam and bloom more. Before planting, apply decomposed organic fertilizer as base fertilizer in the hole, and then apply fertilizer four times a year, that is: apply germination-inducing fertilizer once in February-March, apply flower-inducing fertilizer once before flowering; Enhance the growth of plants; apply a winter fertilizer when the leaves fall before winter, the amount can be slightly more, which is beneficial to increase the ground temperature and make the plants survive the winter safely. [0003] For potted roses...
