Abstract

The invention provides a method for promoting flowering and fruiting of liquorice root. The method is applied to the liquorice root growth process and adopts the technical route of spraying an exogenous substance to activate endogenous substance transformation. The method comprises the following steps: (1) selecting a KH2PO4 solution with mass fraction of 0.10-0.30% as an exogenous promoting substance; and (2) implementing technology: spraying the selected exogenous promoting substance to the heads of seedlings by adopting a sprayer in the period of emergence, the period of closing of crops, the squaring period, the flowering period and the fruiting period of liquorice root seedlings. The method has the advantages that in cooperation with reasonable field management, flowering and fruiting of liquorice root can be effectively promoted, the yield and quality of liquorice root seeds can be obviously increased and the planting requirements can be met; and compared with methods for naturally growing liquorice root seedlings, the method provided by the invention has the advantages that the plant height of liquorice root can be increased to 27cm, the addition of the branching number of each seedling is 2 on average, the addition of the panicle number can be 25, the addition of the pod number is 204, the addition of the seed number is more than 300, and the seed frequency is 3.3%.

Description

A kind of method promoting Radix Glycyrrhizae to blossom and bear fruit

Technical field

The invention belongs to field of plant growing technology, it is related to promote the solid method of flowering of plant, refers specifically to a kind of promotion The method that Radix Glycyrrhizae blossoms and bears fruit.

Background technology

Radix Glycyrrhizae, as conventional bulk medicinal materials, is widely used in multiple industry such as medicine, chemical industry and food, all has both at home and abroad Very big demand, in recent years China Radix Glycyrrhizae annual requirement reached 15000 tons about, wherein, annual export volume be about 5,000 6000 Ton, only Korea S every year from China import Radix Glycyrrhizae and 3,000 4000 tons of Radix Glycyrrhizae agreement that contracts a film or TV play to an actor or actress, the how transit pin with health product name import Toward the country such as Japan, Germany, France, U.S..Reduce year by year with wild resource, the market of Radix Glycyrrhizae improve year by year, disparities between supply and demand Become increasingly conspicuous.For solving the disparities between supply and demand of Radix Glycyrrhizae, meet the market demand, development Licorice Farmland plantation, become the certainty of people Select.But Radix Glycyrrhizae blossoms and bears fruit later, it has also become the Main Bottleneck that Glycyrrhiza Seeds are bred, how to promote Radix Glycyrrhizae nutritious as early as possible Grow into reproductive growth, be in Radix Glycyrrhizae industry, to continue one of problem in science of research.

Content of the invention

The technical problem to be solved is to provide a kind of conversion activating inherent material by allogenic material, realizes Promote the method that Radix Glycyrrhizae blossoms and bears fruit.

For solving the above problems, a kind of method promoting Radix Glycyrrhizae to blossom and bear fruit of the present invention, refer in growth of Glycyrrhiza uralensis During, take the technology path of the conversion spraying the inherent material of allogenic material activation, comprise the following steps：

（1）The selection of allogenic material：Select the KH that mass fraction is 0.10 0.50%₂PO₄Solution promotes material as external source；

（2）Technology implementation：In the key developmental stages of Radix Glycyrrhizae seedling, using aerosol apparatus, selected allogenic material is sprayed to seedling The symptom of a trend.

Further, described KH₂PO₄The preferred mass fraction of solution is 0.10 0.30%.

Further, described Radix Glycyrrhizae seedling is the Glycyrrhiza uralensis Fisch. seedling transplanted latter 3 years.

Further, the key developmental stages of described Radix Glycyrrhizae are the seeding stage, seal ridge phase, squaring period, florescence and fruiting period.

The present invention compared with prior art has advantages below：

The present invention apply spray in growing process allogenic material activation in material conversion theory, divided using quality The KH for 0.10 0.50% for the number₂PO₄Solution as external source promote material, respectively growth of Glycyrrhiza uralensis seeding stage, envelope the ridge phase, budding Phase, florescence and fruiting period spray, and coordinate rational field management, can effectively facilitate Radix Glycyrrhizae and blossom and bear fruit hence it is evident that improving Glycyrrhiza Seeds yield and quality, meets plantation demand.By finding with growth Radix Glycyrrhizae seedling contrast naturally：Side of the present invention Method can improve Radix Glycyrrhizae plant height and reach 27cm, and the branch amount of averagely every plant seedling increases number and reaches 2, and fruit ear number increases number up to 25 Individual, Fruit pod number increases by 204, and seed number increases by more than 300, and seed frequency reaches 3.3%.

Specific embodiment

By embodiment, the present invention and its effect will be described further below.

Embodiment 1：

（1）Prepare the KH that mass fraction is 0.10%₂PO₄Solution；

（2）Respectively in seeding stage of the transplanting Glycyrrhiza uralensis Fisch. seedling early growth of latter 3 years, envelope ridge phase, squaring period, florescence and knot Fruiting period, using aerosol apparatus by the KH being prepared₂PO₄Solution sprays to the seedling symptom of a trend.

Embodiment 2：

（1）Prepare the KH that mass fraction is 0.20%₂PO₄Solution；

Embodiment 3：

（1）Prepare the KH that mass fraction is 0.30%₂PO₄Solution；

Randomly draw the Radix Glycyrrhizae seedling sample in 10 plants of above-described embodiments respectively, and 10 plants of Radix Glycyrrhizae seedlings naturally growing, Statistics plant height, branch amount, fruit ear number, Fruit pod number, the meansigma methodss of seed number, average Fruit pod dry weight and seed weight, calculate seed Frequency, result is as follows：

Can be seen that from above testing result, the plant height of 3 embodiment samples, branch amount, fruit ear number, Fruit pod number, seed number, average Fruit pod dry weight and the meansigma methodss of seed weight, compared with the seedling of growth naturally, have all obtained largely increasing, especially Seed amount increased 300, and seed frequency increased 3.3%, and therefore, the present invention can effectively facilitate Radix Glycyrrhizae and blossom and bear fruit, bright Aobvious raising Glycyrrhiza Seeds yield and quality, meets plantation demand.
