A planting method for preventing bolting of rhubarb

Abstract

The invention discloses a planting method capable of preventing rhubarb from bolting, and belongs to the technical field of Chinese herbal medicine planting. The planting method comprises the steps that the rhubarb and soybeans are interplanted, topdressing is combined, processing is performed with plant chlormequat chloride and garlic water, summer seedling is performed with seeds produced by three-year-old rhubarb, and the transplant depth is strictly controlled at 33-35 cm. According to the planting method, the rhubarb and the soybeans are interplanted, the soybeans have the nitrogen fixation function and compete with the rhubarb for nitrogen nutrition, the nitrogen nutrition supply of the rhubarb is reduced, nitrogen serves as a photosynthesis site of many kinds of enzymes and can improve the photosynthesis efficiency, and therefore the photosynthesis efficiency of the rhubarb is reduced; meanwhile, temperature control is combined, and therefore the rhubarb is effectively prevented from bolting.

Description

technical field [0001] The invention belongs to the technical field of planting Chinese medicinal materials, in particular to a planting method for preventing bolting of rhubarb. Background technique [0002] Rhubarb is a perennial herb of the Polygonaceae Rhubarb genus. The cultivated varieties include Rhubarb palmatum, Rhubarb tangut, medicinal rhubarb and edible rhubarb. Rhubarb in my country is mainly used as medicine. Its rhizomes and roots are used as medicine. It tastes bitter and cold, and has the functions of purging water and laxative, breaking accumulation and removing blood stasis. One of Chinese herbal medicines. Rhubarb likes high cold, humid and cool climate, and is afraid of high heat. It is mainly produced in Qinghai, Gansu, Sichuan and other provinces. [0003] In production, three-year-old rhubarb has high medicinal ingredients, high yield, and the best benefit. However, in the second year after planting, rhubarb appears bolting phenomenon, which inhibits...

AI Technical Summary

Problems solved by technology

Although the method of preventing plant bolting disclosed in the above report can effectively suppress the bolting phenomenon, it has high requirements for planting field facilities, such as early warming and seedling cultivation, internal and external sunshade nets and cooling curtain fans, greenhouse container seedling cultivation, and green body transplantation with substrates. Planting requires greenhouses or other facilities to control light and temperature, which undoubtedly increases production costs, and when the temperature is high in summer, the effect of adjusting through sunshade nets and cooling equipment is not obvious, and there are still a large number of bolting phenomena
