Abstract

The invention discloses a management method for prolonging flowering period of sweet osmanthus in a severe environment. The management is carried out from 2 months before start of the flowering period to one week after the flowering period finished, wherein an amino acid foliar fertilizer is sprayed on the sweet osmanthus and an organic fertilizer is used for root irrigation. Compared with the prior art, the method achieves nutrition supplement during the flowering period of the sweet osmanthus, and a problem of low blossom quantity caused by influence of harmful substances due to pollution is avoided. Meanwhile, the amino acid foliar fertilizer can increase hydrophilic colloid in plant cells, thereby improving absorption and storage of nutrients and retaining sufficient carotene and anthocyanin. The management method can prolong the flowering period and improve the resistance of the sweet osmanthus in the severe environment.

Description

The management method at Flos Osmanthi Fragrantis florescence in a kind of prolongation adverse circumstances

Technical field

The invention belongs to nursery stock cultural technique field and in particular in a kind of prolongation adverse circumstances the Flos Osmanthi Fragrantis florescence manager Method.

Background technology

Flos Osmanthi Fragrantis are China's tradition one of ten big famous flowers, integrate greening, beautification, sweetening treatment view and admire with practical have both excellent Good Landscape Tree Species, can with Flos Osmanthi Fragrantis for raw material make osmanthus flower tea, soft aroma and, delicious taste, by masses liked, Flos Osmanthi Fragrantis are in garden Woods has a wide range of applications in building, and Flos Osmanthi Fragrantis coriaceous leaf has the ability of necessarily resistance to smoke contamination, but after standing environmental pollution, meeting Only coming into leaves the situation do not bloomed occur, and present Flos Osmanthi Fragrantis are generally planted in road both sides or industrial park with Landscape Tree Species, automobile The problems such as tail gas, industry manufacture progressively intensification, lead to the Flos Osmanthi Fragrantis amount of blossoming few, florescence shorter problem.

Content of the invention

The purpose of the present invention is for existing problem, there is provided the manager at Flos Osmanthi Fragrantis florescence in a kind of prolongation adverse circumstances Method.

The present invention is achieved by the following technical solutions: a kind of management method extending the Flos Osmanthi Fragrantis florescence in adverse circumstances, Start first 2 months to terminate to be managed in a rear week to the florescence from the florescence, concrete management method includes herein below:

(1) with 7 days as cycle, sprayed to plant using amino acid foliage fertilizer, described amino acid foliage fertilizer is by following weight proportion Fermenting raw materials form: 100 parts of bean cake powders, 150 parts of water, 2 parts of rhodotorula glutinis, 15 parts of fish protein powders, 8 parts of robe powder, will be above-mentioned After raw material mixing, keeping temperature is 26-30 DEG C, ferments 15-25 days, obtains fermentation material, drying to moisture is 32-36%, Ran Hou Add in fermentation material and be equivalent to the brown sugar water that 8 times of mass concentrations of its weight are 6%, soak under conditions of pressure is for 1.5-1.8mpa Bubble 8-10 days, is extracted with vacuum pump and obtains amino acid foliage fertilizer；

(2) with 10 days as cycle, irrigate plant root with organic fertilizer, organic fertilizer by 5 parts of nitrogen-phosphorus-potassium compound fertilizers, 2 parts efficiently After lambda-cyhalothrin, 1 part of caryophyllene, 1 part of safflower oil and 1 part of additive mix homogeneously, 800 times of water dilutions are added to obtain；

Wherein, described additive is put in the first washing water of rice being equivalent to 3 times of weight portion for Radix Tripterygii Wilfordii powder, in 40-50 DEG C of bar Under part, sealing is taken out after placing 3 days, adds the brown sugar being equivalent to its weight portion 15%, and keeping temperature is 35-40 DEG C, and sealing is put After putting 5 days, stand overnight after being cooled to room temperature and obtain final product.

As further improvement of these options, in described nitrogen-phosphorus-potassium compound fertilizer, the weight of N P and K is than for 4:2:3.

Due to air pollution and soil pollution in adverse circumstances, plant stem hydropenia and nutrition, existing management can be led to Method is usually periodically applied fertilizer and is watered it is impossible to ensure the absorption of plant nutrition, in amino acid foliage fertilizer add fish protein powder and Spore powder so as to stem accumulates enough sugars and nutrition before the florescence, irrigate plant root, make plant thin by cooperation organic fertilizer Intracellular hydrophilic colloid is strengthened so as to keep relatively mild respiratory frequency, stable growth；Continue to apply aminoacid leaf at the florescence Leaven, can aid in the accumulation of content and the storage of the internal carotene of plant and anthocyanidin so as to persistently keep nutrition to contain Amount, thus extend the florescence bloomed；After the florescence, because florescence plant nutrition demand is more, magnitude of recruitment is basic with demand Balance, terminates the initial stage at the florescence, nutritional requirement does not directly reduce, if nutritional supplementation quickly reduces, may result in plant Strain is come to harm due to nutritional imbalance, reduces its resistance, may result in flowering delay next time.

The present invention has the advantage that compared to existing technology and carries out nutrition using management by methods in the present invention to the Flos Osmanthi Fragrantis florescence Supplement, it is to avoid it is led to the few problem of the amount of blossoming due to pollution by harmful substance impact, pass through amino acid foliage fertilizer simultaneously Reinforcement to plant cell hydrophilic colloid, the absorption of raising nutrition and storage are so as to keep sufficient carotene and cyanine Element, thus kind of blooming period prolonging, improves resistance in adverse circumstances for the osmanthus fragrans.

Specific embodiment

Embodiment

The management method at Flos Osmanthi Fragrantis florescence in a kind of prolongation adverse circumstances, one after the florescence starts first 2 months to terminate to the florescence Individual week is managed, and concrete management method includes herein below:

Wherein, in described nitrogen-phosphorus-potassium compound fertilizer the weight of N P and K than for 4:2:3.

By terminating the initial stage from florescence the first two months to florescence, it is managed in the present embodiment, improves Flos Osmanthi Fragrantis plant pair The absorption of nutrition and accumulation, arrange controlled trial 1, the heavier road of emission on both sides of the road while the osmanthus fragrans planted enter line pipe Reason, the wherein osmanthus fragrans of side fertilizing, watering according to a conventional method, as a control group 1；Opposite side enters according to method in the present embodiment Line pipe is managed, as experimental group 1；Record is bloomed situation, and wherein matched group is bloomed sparse, and Flos Osmanthi Fragrantis fragrance is thin, and the florescence is 30- 40 days, the fragrance of flowers is strong for experimental group, blooms dense, and the florescence reaches more than 60 days, compares matched group and has clear improvement；

Setting matched group 2, the heavier road of emission on both sides of the road while the osmanthus fragrans planted be managed, the wherein osmanthus of side Hua Shu is managed by the present embodiment method, but stops spraying foliage fertilizer and pouring organic fertilizer, as right after the florescence terminates According to group 2；Opposite side is managed according to method in the present embodiment, as experimental group 2；Continuous cultivation 2 years, situation that it is bloomed Recorded；Wherein matched group 2 and experimental group 2 are essentially identical in First Year upgrowth situation, bloom dense, the fragrance of flowers is strong, but The flowering delay of Second Year matched group 2 7-10 days, also there is certain shortening at the corresponding florescence.

Tested from two above, in the present invention, method improves significantly to the Flos Osmanthi Fragrantis plant in adverse circumstances, Improve Flos Osmanthi Fragrantis to blossom rate, kind of blooming period prolonging, remarkable in economical benefits.
