Problems solved by technology

[0007] At present, there are four main problems in the cultivation of osmanthus fragrans. One is that there are few varieties and the flowering period is concentrated; the other is that it takes a long time for some flower quality Jingui, Yingui and Dangui to enter the flowering period, and the childhood period takes 10 years. About to enter the flowering period
The third is that there is no plastic pruning, the tree shape is chaotic, the tree is too high, the flowering is bulbous, and the flowering parts are moved outwards, resulting in the reduction of flowering parts; the fourth is the lack of guidance on fertilizer and water management and pest control, resulting in unbalanced vegetative growth and reproduction
Above factors all cause the output of sweet-scented osmanthus to be low, and an adult sweet-scented osmanthus tree strain produces less than 5kg
Therefore, the income of flower farmers is not high, and their enthusiasm is affected; the raw material supply of processing enterprises is insufficient, and they are in a state of half-year production and half-year idleness, which affects the benefits of enterprises

Embodiment 1

[0023] Premature cultivation experiment: The experiment was carried out in the Osmanthus Garden of Xian'an Campus of Hubei University of Science and Technology. The variety is Osmanthus osmanthus in the autumn osmanthus category. The 2-year-old plant with more branches was selected and grew vigorously. The 2-year-old plant was planted in the autumn of 2003, with a height of 0.8m.

[0024] During the growing season of 2004 from March to October, apply quick-acting fertilizer every 2 months, apply 3-5kg of human excrement and urine or 50-100g of urea to each tree at a concentration of 1:5, and fertilize in circular furrows with a depth of 10 ~15cm; at the same time, spray 0.2%~0.5% urea or 1500~3000ppm gibberellin on the leaves every half a month; apply base fertilizer once in autumn, mainly organic fertilizers such as decomposed manure or cake fertilizer, 5~10kg per plant , the depth is 30-40cm, and the ring-shaped ditch is applied. In 2005, on the basis of fertilization in 200...

Embodiment 2

[0028] The high-yield cultivation experiment of adult trees was carried out in the second group of Guihua Village, Guihua Town, Xian'an District in 2007.

[0029] The tree with strong growth potential is 14-year-old silver osmanthus, planted on flat land, 3 trees per treatment, repeated 3 times, a total of 9 trees, the average yield in 2006 was 2.5 Kg. The treatment method is (1) fertilization: do not apply basal fertilizer to the trees with strong growth potential, apply flower fertilizer from June to August, apply 25-50kg of human excrement and urine or 100-300g of urea to each tree at a concentration of 1:5, and apply along the drip line of the crown Apply in circular furrows with a depth of 10-15cm. (2) Pruning: Girdle the vigorously growing main branches, girdling as deep as the xylem, 2-3mm wide, and girdling twice, once in April and June, to achieve the purpose of inhibiting vegetative growth and promoting flower bud differentiation. In September 2007, the calculated o...

Abstract

The invention discloses a high-efficiency cultivation technology for early and highly producing osmanthus fragrans. The cultivation technology is characterized in that early production and high production of the osmanthus fragrans are promoted by different fertilizer-applying and trimming technologies. The cultivation technology comprises the following steps of: promoting the rapid growth of the osmanthus fragrans by combination of small-amount multiple fertilizer application and fertilizer spraying on the leaves in the growing seasons in 2-3 years after the osmanthus fragrans is planted, and at the fourth year, adopting branch pulling and girdling to control fertilizer application and promote flower bud differentiation so as to achieve the purpose that the osmanthus fragrans flowers in advance by 2-3 years. The high-efficiency cultivation technology disclosed by the invention has the advantages that the vegetative growth of the osmanthus fragrans is inhibited by intermittent fertilizer application and twice girdling to the osmanthus fragrans with strong growth vigor so as to promote the flower bud differentiation, and repeated and more fertilizer application is adopted for trees with weak growth vigor to restore the tree vigor, so that the flowering parts are added, and the yield is increased by about 20% compared with the yield of the conventional cultivation.

Description

technical field [0001] The invention belongs to the agricultural planting technology, in particular to a high-yield and high-efficiency cultivation technology of sweet-scented osmanthus. Background technique [0002] Osmanthus fragrans( Osmanthus fragrans Lour .) Belonging to the Osmanthus family, it is a unique evergreen broad-leaved shrub or small tree economic tree species in China. It is native to the mountainous areas of southwest my country and has a cultivation history of more than 2,500 years. [0003] With the improvement of people's material and cultural living standards, the requirements for urban landscaping are getting higher and higher. It is not only required to achieve greening, but also to achieve the goals of beautification, fragrance, color and perennial green. Among many landscaping tree species, only osmanthus can approach this goal. Osmanthus fragrans is elegant in appearance, jasper is like a cloud, and osmanthus core is fragrant, refreshing. It is...
