Photinia frugiperda has been widely used in foreign countries, especially in Europe, America and Japan, and is known as the "King of the Red Hedges". Its market prospects are broad and its development potential is huge. Ginseng privet is the new color leaf of Japanese privet series, and the color of the leaves is lightness. The higher golden color is praised by the industry as "the golden partner of Photinia frasery"; the Phnom Penh Cyclovirobuxia is an evergreen shrub with resistance to yin, drought and cold. The variety is yellow throughout the year in garden patches, which is of positive significance to the diversification of yellow plant species in garden patches.
The demonstration and promotion of the project is to increase the economic benefits of the farmers and guide the development of the farmers to diversified industries. In 2012, the project team of the Nanjing Institute of Agricultural Sciences demonstrated and popularized the Photinia serrulata, Jinsen Privet and Phnom Penh Cyclovirobuxine in the two districts of Jiangning and Pukou. Color seedlings and other new varieties. In the process of popularization, the technical results of the integrated color seedling seedling breeding and container seedling cultivation are utilized to greatly improve seedling emergence rate and quality and reduce production costs.
1. Build 200 acres of green seedling cultivation demonstration bases in Jinling Green Valley Modern Gardening Science and Technology Demonstration Park in Jiangning, producing more than 3 million seedlings such as Photinia, and in Houchong Village and Wadian Village of Tangquan Town, Yongning Town, Pukou District and around Regional radiation promotion; in 2012, a total of 1.2 million colored container seedlings were transplanted in the seedling flower science and technology demonstration park of Houchong Village, Yongning Town, and 700,000 colored seedlings were planted in spring. Adopt the model of "base + large households + farmers" model promotion.
2. Establish a seedling flower science and technology demonstration base in Houchong Village, Yongning Town, and formulate Technical Regulations for Production of Containers of Photinia fraseri, and cultivate a number of technology demonstration households.
Technical points
1. Cutting propagation techniques Cutting time: late April to late June, late August to mid-October.
Cutting matrix: Garden soil + rice husk + vermiculite were mixed in a 2:1:1 volume ratio.
Cuttings were cut: they were cut into leaves and buds (length about 5-7 cm) with semi-woody shoots or lignified branches of the year.
Cutting treatment and cutting: as far as possible with the scissors plug. Prior to cutting, the incision was treated with a rooting agent such as naphthaleneacetic acid. The cutting depth is appropriate to about 3 cm. Immediately after the insertion, water is irrigated and the leaves are sprayed with carbendazim and anthraquinone mixture.
Post-insertion management: After the cutting, the air humidity in the arch shed should be kept above 85%, and the temperature should be controlled below 38°C. Shave more than 75% of the shade before cutting it from roots to hair roots. When all the cuttings are rooted and more than 50% of leaves are generated, shade nets and films are gradually removed, and foliar fertilizer or low-concentration water-soluble fertilizers are sprayed at the same time to promote robust growth of the cuttings.
2. Container seedling cultivation technique containers: 10 cm nutrient bowls are used for semi-annual container seedlings, 15 cm nutrient bowls are used for 1 year container seedlings, and 18 cm nutrient bowls are used for 2 year container seedlings.
Matrix: Garden soil, peat, cocoon, pine scales, fine sand, perlite, etc. The content of inorganic matrix is ​​about 20%.
Fertilizer management: After a new root grows, it begins to be applied with 0.3% aqueous solution of body fat, urea and compound fertilizer are used for alternate pouring, and it is poured once every 10 to 15 days.
Pest control: Diseases mainly include anthrax and leaf spot diseases. The control agent has 50% carbendazim 500 times solution, 50% thiophanate WP 800 to 1000 times, etc., spraying once every 7-10 days for 3 to 4 consecutive times. Root diseases can be treated with 800 to 1000 times the enemy root irrigation. Insect pests mainly include aphids and moth larvae. Using periodic spraying control, 800 times imidacloprid, 90% trichlorfon 1000 times and so on were used.
Market Outlook and Benefit Analysis Project Implementation Point Houchong agricultural cultivation cooperatives in Pukou District organized farmers to adopt land transfer, land equity and other forms to achieve large-scale production and standardized planting, and adopted the “market joint company, company plus base, and base with farmer householdsâ€. Industrialization model. Recently, 2 million strains of container seedlings such as Photinia serrulata, Phnom Penh Cyclovirobuxine, and Jinsen Privet were produced annually. The market price was calculated at 1.5 yuan per plant, with sales of 3 million yuan, profit of more than 2 million yuan, and an average yield of about 3 acres. Ten thousand yuan. At the same time, it also provided a large number of jobs for local farmers.
Glass Venlo Greenhouse is Spire-type glass design, design and installation of windows when more convenient and easy. Its roof slope andle can be appropriately according to the local real climate change the environment.
In Venlo greenhouse, foundation is made of reinforced concrete and the side wall is made of brick or reinforced concrete plate. the steel frame always use hot dip galvanized light steel. Roof beam adopts horizontal girder structure and using herringbone connection. The horizontal girder bears 2 or more roofs, which is made of aluminum alloy. This material is used as roof structure material and also glass inlay material. Other beams using gutter style to minimize the section. Delighting material of the roof and side wall using 4 mm thick float glass.
