Description
Technical Field
The invention relates to a propagation and cultivation technology of oil peonies, in particular to a method for delaying the falling leaves of the oil peonies.
Background
The peony for oil is a new woody oil crop, and has the outstanding characteristics of three highs and one lowness: high yield (the five-year yield per mu can reach 300 kilograms, the comprehensive benefit per mu can reach ten thousand yuan), high oil content (the oil content of seeds is 22%), high quality (the content of unsaturated fatty acid is 92%), low cost (the oil peony is drought-resistant and barren-resistant, is suitable for afforestation and forestation of barren mountains, is harvested in one hundred years and is low in cost).
The peony for oil can be used as an oil crop and has great ornamental value. The oil peonies cultivated by the prior art have fallen leaves after going over summer, a dead branch in the peony garden and lack of green leaf vitality, and the ornamental effect of the peony garden is seriously influenced; and the early defoliation period causes less nutrient accumulation, insufficient branches, less flower bud differentiation, weak tree vigor and easy secondary flowering, and directly influences the yield of the next year.
Disclosure of Invention
In order to delay the fallen leaves of the oil peonies and ensure that the ornamental period is longer and the yield of the next year is increased, the invention provides the following technical scheme:
a method for delaying the leaf falling of oil peony comprises spraying a combination agent of a bactericide and cytokinin on plants respectively in 5 periods before planting, during the leaf spreading period, during the flowering period, during the fruit ripening period and after fruit harvesting; the bactericide is one or the combination of two of carbendazim and chlorothalonil; the cytokinin is one or the combination of two of KT and 6-BA.
The cytokinin can promote cell division and regulate differentiation, is beneficial to flower bud differentiation, can increase sugar content and alkaloid of peony for oil, enhance photosynthesis to promote growth, improve plant immunity, improve agricultural product quality and increase yield; the cytokinin also has the function of delaying the degradation of protein and chlorophyll and can delay aging; the 5 periods are the most vigorous periods of cell division, and the spraying of cytokinin is the best in effect and the highest in efficiency. The bactericide can kill bacteria, fungi and microorganisms, reduce the probability of plant infection diseases, and has synergistic effect on the bactericidal effect when being used together with cytokinin.
Further, the method comprises the following steps:
s1, before planting the oil peony: spraying 700-900 times carbendazim solution and 6-BA combined medicament with the concentration of 18-22mg/L on the plants; the carbendazim is a systemic bactericide, and the spraying of the carbendazim before the planting of the plants can enable the plants to generate antibacterial property; the 6-BA has the main function of promoting the formation of buds, and the application of the 6-BA with higher concentration before planting is beneficial to improving the survival rate of planting and improving the activity of plant cells;
s2, leaf unfolding period: spraying 1000-1200 times of chlorothalonil liquid and KT combined medicament with the concentration of 32-38mg/L on the plants; the chlorothalonil has no systemic conduction effect, can only be adhered to the surface of a plant body, has a long drug effect, and is sprayed due to the long interval from the leaf spreading period to the flowering period; KT is an unnatural cytokinin, and has the effects of delaying the aging of in-vitro leaves and cut flowers, inducing bud differentiation and development, and increasing stomatal aperture in addition to the effect of promoting cell division.
S3, flowering period: the plant is sprayed with the combined agent of carbendazim 700-900 times liquid, chlorothalonil 1200-1500 times liquid, 6-BA with the concentration of 8-12mg/L and KT with the concentration of 8-12 mg/L; the combination of the carbendazim and the chlorothalonil is adopted in the flowering period, so that the sterilization effect can be enhanced, the long pesticide effect can be kept, and a good growth environment is provided for plant fruiting; and 6-BA and KT are used in combination to further enhance the cell differentiation effect and delay the leaf senescence.
S4, fruit mature period: spraying 1000-1200 times of chlorothalonil liquid and 6-BA combined medicament with the concentration of 6-10mg/L on the plants; the 6-BA with lower concentration is applied in the fruit ripening stage, so as to prevent the 6-BA with high concentration from generating antagonistic action to hinder the fruit ripening under the condition of ensuring the effect of prolonging the fallen leaves;
s5, harvesting the fruits: the plant is sprayed with a combined agent of carbendazim 800-1000 times liquid, chlorothalonil 1000-1200 times liquid, 6-BA with the concentration of 13-17mg/L and KT with the concentration of 8-10 mg/L.
Further, the method comprises the following steps:
s1, before planting the oil peony: spraying 800 times of carbendazim solution and a 6-BA combined medicament with the concentration of 20mg/L on the plants;
s2, leaf unfolding period: spraying a chlorothalonil 1100-fold liquid and a KT combined medicament with the concentration of 35mg/L on the plants;
s3, flowering period: spraying a combined medicament of 800 times of carbendazim liquid, 1350 times of chlorothalonil liquid, 6-BA with the concentration of 10mg/L and KT with the concentration of 10mg/L on the plants;
s4, fruit mature period: spraying 1100 times of chlorothalonil liquid and 6-BA combined medicament with the concentration of 8mg/L on plants;
s5, harvesting the fruits: the plant is sprayed with a combination medicament of carbendazim 900 times liquid, chlorothalonil 1100 times liquid, 6-BA with the concentration of 15mg/L and KT with the concentration of 9 mg/L. The combination of the bactericide and the cytokinin with the concentrations has the best effects of delaying the falling leaves of the peony for oil and increasing the yield.
The invention has the beneficial effects that: the retention period of the oil peony leaves can be prolonged by 15-20 days, the ornamental period of the oil peony is prolonged, and the yield of the oil peony in the next year is increased.
