Description

Cucumber growth regulator and sunlight greenhouse cucumber planting method
Technical Field
The invention belongs to the technical field of promoting high-yield cultivation of plants, and particularly relates to a cucumber growth regulator and a sunlight greenhouse cucumber planting method.
Background
The sunlight greenhouse and the plastic greenhouse are effective equipment for realizing vegetable planting in winter and spring in north China, but because the plastic greenhouse and the sunlight greenhouse in China are generally simple and crude and lack necessary environment regulation and control equipment for temperature, light, water, gas and the like, sub-suitable environments such as low temperature, weak light, high humidity and the like exist in facilities in winter and spring for a long time. The cucumber belongs to a temperature-loving crop, is one of main vegetables for facility cultivation in northern China, and due to the fact that a sub-suitable environment exists in the facility for a long time, the chlorophyll content of the cucumber can be reduced, the activity of carbon assimilation related enzyme is inhibited, photosynthesis is hindered, growth is delayed and the like, and the growth and yield of the cucumber are seriously influenced.
At present, the main research for improving the yield of plants is based on the synergistic effect of a plurality of fertilizer mixtures. For example, patent invention CN102531778A discloses a water-soluble fertilizer containing 5-aminolevulinic acid chemical modifier, which contains protein peptide, water-soluble chelated sucrose, trace element mixture, 5-aminolevulinic acid chemical modifier and penetration enhancer. The water-soluble fertilizer is prepared by combining a plurality of components, the preparation process is complex, and the plurality of fertilizers are added simultaneously, so that the fertilizer and the water cannot be reasonably applied and irrigated according to the growth condition of crops, and the fertilizer and the water are wasted to cause fertilizer damage. In addition, the stability of the chemical modifier of 5-aminolevulinic acid in the water-soluble fertilizer is not high, and the chemical modifier is preferably applied at low temperature at night or in the shade after being applied in the day, namely the operation is not easy. In addition, the water-soluble fertilizer is not suitable for greenhouse soil planting of long-term continuous cropping, and because the greenhouse soil of long-term continuous cropping is easy to cause plant diseases and insect pests and the porosity of the soil is low, various components in the water-soluble fertilizer are not uniformly distributed in the soil and are not easy to be absorbed by plant roots. In summary, the stability and availability of the various ingredients in water-soluble fertilizers, especially 5-aminolevulinic acid, is not high.
Disclosure of Invention
The invention aims to solve the problems of frequent diseases and insect pests of continuous cropping soil of a sunlight greenhouse and low stability and utilization rate of 5-aminolevulinic acid regulators in the prior art. The invention provides a cucumber growth regulator and a sunlight greenhouse cucumber planting method, so that the plant diseases and insect pests of cucumber growth can be reduced, the stability and the utilization rate of a 5-aminolevulinic acid regulator are improved, and the yield of cucumber is obviously improved.
In order to achieve the above objects, the present invention provides a cucumber growth regulator comprising 5-aminolevulinic acid and its derivatives, sodium naphthaleneacetate, sodium polynitrophenate, epibrassinolide, levulinic acid and weakly acidic oxidation potential water, wherein the weight ratio of 5-aminolevulinic acid and its derivatives, sodium naphthaleneacetate, sodium polynitrophenate, epibrassinolide and levulinic acid is 1: 1-3: 10-15: 20-30: 1-5, and the dosage of the weakly acidic oxidation potential water is 50-300mL relative to 1mg of 5-aminolevulinic acid and the derivative thereof.
On the other hand, the invention provides a sunlight greenhouse cucumber planting method, which comprises the following steps:
(1) measuring the pH value of the sunlight greenhouse soil to be alkaline, and then adding humic acid to adjust the pH value to 5.5-6.5;

(3) drip irrigation cucumber growth regulator on roots after field planting and seedling revival;
wherein the cucumber growth regulator is the regulator.
In the invention, levulinic acid can improve the stability of 5-aminolevulinic acid and derivatives thereof, and can be used as a stabilizer of 5-aminolevulinic acid and derivatives thereof, while the prior art generally improves the stability of 5-aminolevulinic acid and derivatives thereof by alkylating 5-aminolevulinic acid and the like, namely chemically modifying 5-aminolevulinic acid, but the chemical modification method is complex and high in cost, and whether the chemically modified 5-aminolevulinic acid can also act per se cannot be predicted. The invention can improve the stability of the 5-aminolevulinic acid and the derivative thereof by adding the levulinic acid, and does not influence the functions of other components of sodium naphthalene acetate, compound sodium nitrophenolate, epibrassinolide and weak acidic oxidation potential water. In addition, the inventor creatively applies the weak acidic oxidation potential water to the agricultural field, thereby being capable of preventing the microorganisms in the soil from having adverse effects on the plant absorption of the 5-aminolevulinic acid and the derivatives thereof, further improving the stability and the utilization rate of the 5-aminolevulinic acid and the derivatives thereof, and improving the production yield. In addition, the weak acidic electrolyzed oxidizing water can also properly improve the opening degree of the air pores of the surface cells of the roots and the permeability of the cell walls, so that the permeability of the roots is maintained in a stable range, and the 5-aminolevulinic acid and the derivatives thereof, sodium naphthalene acetate, sodium compound nitrophenolate and surface brassinolide are more stably and continuously absorbed by the roots of plants, thereby remarkably improving the yield of the cucumbers under the condition of suboptimal temperature.

Preferably, the weight ratio of the 5-aminolevulinic acid and the derivatives thereof, sodium naphthaleneacetate, sodium nitrophenolate, epibrassinolide and levulinic acid is 1: 1.5-2: 10-12: 24-26: 2-3, relative to 1mg of 5-aminolevulinic acid and the derivative thereof, the dosage of the weak acidic oxidation potential water is 100-200mL, so that the stability and the utilization rate of the 5-aminolevulinic acid and the derivative thereof can be further improved, the yield of the cucumber can be further improved, and the plant diseases and insect pests of the cucumber can be reduced.
Those skilled in the art know that weakly acidic electrolyzed oxidizing water is commonly used as a disinfectant in the medical field. The inventor of the present invention found in research that, although the decomposition rate of 5-aminolevulinic acid and derivatives thereof is still high under sub-moderate temperature conditions, through continuous experiments, it was found that various pests, such as downy mildew, powdery mildew, bacterial angular leaf spot, corynespora leaf spot, root knot nematode disease and the like, exist in greenhouse soil for continuous cropping of cucumbers, and the pests can seriously affect the stability and utilization rate of 5-aminolevulinic acid and derivatives thereof, sodium naphthalene acetate, sodium nitrophenolate, and epibrassinolide, and in addition, long-term application of alkaline fertilizers may also be one of the reasons for the high decomposition rate of 5-aminolevulinic acid and derivatives thereof. The inventor creatively applies the weakly acidic electrolyzed oxidizing water to the agricultural field, thereby being capable of preventing the microorganisms in the soil from having adverse effects on the plant absorption of the 5-aminolevulinic acid and the derivative thereof, further improving the stability and the utilization rate of the 5-aminolevulinic acid and the derivative thereof and improving the production yield. In addition, the weak acidic oxidation potential water can moderately improve the openness of the air pores of the surface cells of the roots and the permeability of the cell walls so as to improve the activity of the roots of the seedlings and maintain the permeability of the roots in a stable range, so that the 5-aminolevulinic acid and the derivatives thereof, sodium naphthylacetate, sodium nitrophenolate and epibrassinolide are more stably and continuously absorbed by the roots of the plants.
Furthermore, the inventors of the present invention have found through research that levulinic acid can improve the stability of 5-aminolevulinic acid and derivatives thereof and can be used as a stabilizer for 5-aminolevulinic acid and derivatives thereof, whereas in the prior art, the improvement of the stability of 5-aminolevulinic acid and derivatives thereof is generally performed by chemically modifying 5-aminolevulinic acid, such as alkylating 5-aminolevulinic acid, but such a chemical modification method is complicated and costly, and it is unpredictable whether chemically modified 5-aminolevulinic acid itself can still function. The invention can improve the stability of the 5-aminolevulinic acid and the derivative thereof by adding the levulinic acid, and does not influence the functions of other components of sodium naphthalene acetate, sodium nitrophenolate, epibrassinolide and weakly acidic oxidation potential water.

According to the regulator, the 5-aminolevulinic acid derivative is 5-aminolevulinic acid hydrochloride and/or 5-aminolevulinic acid phosphate, preferably 5-aminolevulinic acid hydrochloride, so that the stability and the utilization rate of 5-aminolevulinic acid can be further improved, and the yield of cucumbers is remarkably improved.
The regulator according to the present invention preferably further comprises a biosurfactant. In the invention, the biosurfactant can ensure that the 5-aminolevulinic acid and the derivatives thereof, sodium naphthalene acetate, compound sodium nitrophenolate and epibrassinolide have better dispersibility in the solution, and can also make 5-aminolevulinic acid and derivatives thereof, sodium naphthalene acetate, compound sodium nitrophenolate, epibrassinolide, levulinic acid and weak acid oxidation potential water adsorbed on the root of cucumber plants, the weakly acidic electrolyzed oxidizing water can moderately improve the openness of the pores of the surface cells of the roots and the permeability of the walls of the cells, so that the permeability of the roots is maintained in a stable range, therefore, the 5-aminolevulinic acid and the derivatives thereof, sodium naphthalene acetate, compound sodium nitrophenolate and epibrassinolide are more stably and continuously absorbed by the roots of the plants, the long-acting property and the utilization rate of the regulator are ensured, and the yield of the cucumbers can be obviously improved. In addition, the biosurfactant does not cause soil pollution.
Preferably, the biosurfactant is a nonionic biosurfactant, more preferably the nonionic biosurfactant is a saponin surfactant and an alkyl glycoside, and further preferably the weight ratio of saponin surfactant to alkyl glycoside is 1: 1-2, thereby further improving the long-lasting property and the utilization rate of the regulator and further obviously improving the yield of the cucumber. In the present invention, the saponin surfactant may be any of various saponin surfactants conventionally used in the art, and may be, for example, polygala tenuifolia saponin, aescin, quillaic acid, and camelliaside, but is not limited thereto, and polygala tenuifolia saponin is preferable. Alkyl glycosides are available, for example, from Beijing Hanolongda scientific development, Inc. under CAS number 157707-88-5.
Further preferably, the total content of the biosurfactant is 0.07-0.25g relative to 1g of the 5-aminolevulinic acid and the derivative thereof, so that the long-acting property and the utilization rate of the regulator can be further improved, and the yield of the cucumber can be further remarkably improved.
The regulator according to the invention preferably further comprises an amino acid compound fertilizer, wherein the amino acid compound fertilizer comprises glycine, lysine, arginine and ornithine; more preferably, the weight ratio of glycine, lysine, arginine and ornithine is 1: 2-5: 1-2: 0.2-0.6; further preferably, the total content of the amino acid compound fertilizer is 0.1-0.2g relative to 1g of 5-aminolevulinic acid and the derivative thereof.
