Embodiment 1

[0024] In June 2016, 300 neem seeds hanging on the tree with cracked peel and no borers were picked and stored in a cool and dry place to keep the seeds moist and ready for use. In July 2016, the red soil and coconut peat were mixed and stirred at a volume ratio of 4:2. During the stirring process, calcium superphosphate was added at a ratio of 60kg per cubic meter of coconut peat to form a cultivation substrate. Fill the cultivation medium in the seedling-raising container, sow the neem seeds directly in the seedling-raising container, avoid direct sunlight, and the temperature is about 30°C. Disinfect the seedbed with broad-spectrum fungicides such as potassium permanganate or chlorothalonil before sowing.

[0025] After sowing, keep the humidity of the cultivation substrate in the seedling container; before the seed radicle grows, spray fresh water 2 to 3 times a day to keep the seeds and cultivation substrate moist; during the radicle growth and seedling growth period, spr...

Embodiment 2

[0028] In July 2016, 300 neem seeds that were naturally mature and fell on the ground without cracks or moths were collected, stored in a cool and dry place, and kept moist for later use. In July 2016, red soil and coconut peat were mixed and stirred at a volume ratio of 4:4. During the stirring process, calcium superphosphate was added at a ratio of 80kg per cubic meter of coconut peat to form a cultivation substrate. Fill the cultivation medium in the seedling-raising container, sow the neem seeds directly in the seedling-raising container, avoid direct sunlight, and the temperature is about 28°C. Disinfect the seedbed with broad-spectrum fungicides such as potassium permanganate or chlorothalonil before sowing.

[0029] After sowing, keep the humidity of the cultivation substrate in the seedling container; before the seed radicle grows, spray fresh water 2 to 3 times a day to keep the seeds and cultivation substrate moist; during the radicle growth and seedling growth perio...

Embodiment 3

[0032] In January 2017, pick 150 neem seeds hanging on the tree with cracked peel and no moths, pick up 150 neem seeds that are naturally mature and fall on the ground, without cracks and moths, and place them in a cool and dry place Store, keep the seeds moist and set aside. In March 2017, the red soil and coconut peat were mixed and stirred at a volume ratio of 4:3. During the stirring process, calcium superphosphate was added at a ratio of 70kg per cubic meter of coconut peat to form a cultivation substrate. Choose a greenhouse with temperature control ability, fill the cultivation medium in the seedling container, sow the neem seeds directly in the seedling container, avoid direct sunlight, and control the temperature at 26°C. Disinfect the seedbed with broad-spectrum fungicides such as potassium permanganate or chlorothalonil before sowing.

[0033] After sowing, keep the humidity of the cultivation substrate in the seedling container; before the seed radicle grows, spra...

Abstract

The invention belongs to the field of plant cultivation, and relates to a seedling breeding method of seedlings of a mangrove forest plant xylocarpus granatum. The breeding method comprises the following steps: sowing mature xylocarpus granatum seeds into a seedling breeding container filled with a cultivation substrate; after sowing, keeping the humidity of the cultivation substrate in the seedling breeding container; when the seedlings are grown to small seedlings with 4-6 of true leaves and a seedling height of 50-70cm, carrying out seedling hardening by using seawater with gradient salinity; transplanting the seedlings in an overcast day or at dusk; and carrying out shading for 5-7 days. According to the invention, a systematic research is carried out on the collection of the xylocarpus granatum seeds and the germination of the seeds and the like, and the mode of combining the seedling breeding of terrestrial plants with seedling hardening by using seawater with gradient salinity is adopted, so that artificial breeding problem of the mangrove forest plant xylocarpus granatum is solved. The breeding method provided by the invention has the characteristics of simple operation, low seedling breeding cost, short seedling breeding time, high survival rate and the like, provides technical support for industrialized seedling breeding and large-scale planting of the xylocarpus granatum, and lays a foundation for restoring the coastal mangrove forest resources and maintaining the ecological balance of shallow water beaches in China.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and relates to a seedling breeding method, in particular to a seedling breeding method of the mangrove plant neem neem. Background technique [0002] Neem is a mangrove plant belonging to the genus Xylocarpus of the Meliaceae family (Meliaceae). It is mainly distributed in the intertidal zone of tropical and subtropical coasts. It is distributed in Hainan, my country, and grows mixed in mangroves on shallow water beaches. [0003] Neem has the following characteristics: Neem is one of the main tree species of mangroves, which has strong anti-typhoon and soil-fixing protection functions; Neem contains a variety of biologically active components, which can be used for the separation and screening of new drugs. In Southeast Asia, neem is used to treat febrile diseases such as diarrhea, cholera and malaria, as well as insect repellents. A large number of studies have been carried out on the biologic...
