How does the butterfly fruit multiply?

  Butterfly fruit is a genus of oligospecies. This is the only species in China. It is an economic tree that uses both grain and oil. Seed (dry kernel) oil content of 33-39%, protein 15-18%, starch 21-40%, sugar 2.5-12%, refined oil for edible. The wood is light and soft, easy to process, and can be used for construction and other materials. The tree is beautiful, the leaves are thick green, and it is a good tree species for greening on the four sides and towns. So how does the butterfly fruit breed?

How does the butterfly fruit breed?

Breeding method:

Seed reproduction

The seed has a short life span and is extremely prone to loss of germination power. Use the on-demand method to cover the soil by 2--3 cm. Germination and unearthing began 10 days after sowing. The 1-year-old seedlings are 40--50 cm high, and they can be afforested. After planting, pay attention to tending management every summer and autumn, and pay attention to pruning and pruning to promote forest growth.

Sowing and breeding

1. Selection: Before seeding, we must first select the seeds. If the seeds are selected well, it is directly related to whether the seeding can be successful. It is best to use the seeds harvested in the year. The longer the seed is stored, the lower its germination rate. Seeds with full, no defects or deformities are used. Use seeds that are free of pests and diseases.

2, disinfection: disinfection contains two concepts, one refers to the disinfection of seeds, and the other refers to the disinfection of the substrate for sowing. Household disinfection of seeds is usually carried out in a hot water of about 60 °C for a quarter of an hour, and then germinated with warm water for 12 to 24 hours. The best way to sterilize the substrate for sowing is to put it in a pan and fry it, and what pests can burn.

3. Germination: Soak the seeds for 12 to 24 hours with warm water (temperature and wash water) until the seeds absorb water and swell. For very common seeds that are easy to germinate, this work can be done.

4, sowing: For small seeds that are difficult to clamp by hand or other tools, one end of the toothpick can be wetted with water, and the seeds are adhered one by one to the surface of the substrate, covering the substrate 1 cm thick, and then The planted flowerpot is placed in water, the depth of the water is 1/2 -2/3 of the height of the flower pot, so that the water is slowly immersed (this method is called "potted immersion method"); for the hand or other tools The larger seeds are picked up and the seeds are placed directly into the substrate and ordered at a distance of 3 × 5 cm.

    Cover the substrate after sowing, covering a thickness of 2 - 3 times the seed. After sowing, the seeding substrate can be wetted by a sprayer or a fine hole shower. After the soil is slightly dried, the water should be drenched. It is necessary to pay attention to the strength of the watering, so as not to wash the seeds;

5. Management after sowing: After sowing in late autumn, early spring or winter, when the cold wave is low, the plastic pot can be used to wrap the flower pot to protect the moisturizing; after the seedlings are unearthed, the film should be uncovered in time. Let the seedlings receive the sun's light before 9:30 in the morning, or after 3:30 in the afternoon, otherwise the seedlings will grow very weakly; most of the seeds will need to be properly seeded after they are out: Unhealthy seedlings are unplugged, leaving the remaining seedlings with a certain amount of space; when most of the seedlings grow 3 or more leaves, they can be transplanted.

Cutting method

It is often used in the late spring and early autumn to carry out cuttings with the branches of the year, or in the early spring, to use the branches of the year to carry out the old branches.

1. Cutting substrate: It is the nutritive soil or river sand, clay soil and other materials used for cutting. Family cutting is limited to conditions that are difficult to obtain the ideal cutting matrix. It is recommended to use the prepared and sterilized cutting matrix provided by this site; it is also possible to use medium-grain river sand, but rinse it with water several times before use. Do not use river sand in sea sand and saline-alkali areas. They are not suitable for the growth of flower plants.

2. Selection of cuttings: When cutting the branches, when the plants grow vigorously from late spring to early autumn, the thick branches of the year are used as cuttings. After cutting the branches, select the strong parts and cut them into 5 to 15 cm long sections, each with more than 3 leaf sections.

    When cutting the cuttings, it should be noted that the upper cut is cut at about 1 cm above the top of the last leaf section, and the lower cut is about 0.5 cm below the lowermost section, and the upper and lower cuts are To level (the knife is sharp). When hardwood cutting is carried out, after the temperature rises in the early spring, the strong branches of the previous year are selected as the cuttings. Each segment of the cuttings usually retains 3 to 4 knots, and the cutting method is the same as that of the young shoots.

3. Management after cutting

Temperature: The optimum temperature for rooting of cuttings is 20 °C ~ 30 °C, below 20 °C, rooting is difficult and slow; above 30 °C, the upper and lower cuts of cuttings are susceptible to infection by bacteria and decay, and temperature The higher the ratio, the greater the proportion of decay.

    When the temperature is low after cutting, the measures of heat preservation are mainly to wrap the flower pot or container used for cutting with the film; when the temperature is too high after the cutting, the measures for cooling are mainly to shade the cuttings, and to cover the sunlight 50~ 80%, at the same time, spray the cuttings, 3 to 5 times a day, the number of times of sunny days is higher, the temperature is lower, the temperature is lower, the number of sprays is less or not.

Humidity: The relative humidity of the air must be maintained at 75-85% after cutting. The basic requirement for rooting of cuttings is that before the cuttings are rooted, it is necessary to ensure that the cuttings are tender and can be photosynthetically used to make rooting materials. But the rooted cuttings are unable to absorb enough water to maintain the water balance in their bodies.

    Therefore, it is necessary to reduce the water evaporation of the cuttings by spraying: under the condition of shading, the cuttings are sprayed 3 to 5 times a day. The higher the temperature of the sunny day, the more the number of spraying, and the lower the temperature of the rainy days, the lower the number of spraying. Less or not spray. However, if the spray is excessively sprayed, the cuttings are easily infested by the bacteria and rot, because many kinds of germs are present in the water.

Illumination: Cutting propagation is inseparable from the sun's rays, because the cuttings continue to carry out photosynthesis to produce nutrients and rooting substances to supply their roots. However, the stronger the light, the higher the temperature in the cuttings, the more vigorous the transpiration of the cuttings, and the more water consumed, which is not conducive to the survival of the cuttings.

    Therefore, after cutting, the sunlight must be covered by 50-80%. After the root system grows, the shading net is gradually removed: the sunshade net is removed every day at 4:00 pm on sunny days, and the next morning before 9:00 am. Shading net.
