1 hard branch cutting seedlings
1.1 Site Preparation
In mid-April, the sandy or light loamy soil plots were selected, and the rafts were made in north and south directions and other directions. The width was 1.1-1.2m, the length was 10-20m, the raft height was 15cm, and the ravioli width was 15cm. The application amount is 8~10kg/m2. Turn the bed 12~15cm deep, so that the feces and soil are fully mixed, and the smashing is done.
1.2 Cutting Collection and Processing
From January to March, from four-year-old or older plants, combined with winter shear plastic surgery, annual branches with a thickness of 0.4 cm or more were cut and stored in cold pits or caves at 0-5°C. The branches were moistened with sand.
In the middle and late April, the cuttings should be cut and treated with rooting material. The sand cuttings should be removed and the cuttings should be cut at a length of 10-12 cm. There should be 2 or 3 nodes per ear. Cut from the top section 1.0 ~ 1.5cm flat cut, cut under the shear or oblique cut. Each 30 to 50 cuttings are tied into a bundle with base moats. The base length is 2~3cm, immersed in 100~150mg/L indole butyric acid solution for 24~48h.
1.3 Cutting and post-insertion management The cuttings are inserted into the substrate at 8~10cm ear length, and the cutting depth is 8~10cm. The upper section is higher than the substrate 1~2cm. Water is applied to the surface of the bowl and the depth of soaking is not less than 12cm. Afterwards, the black agricultural film is buckled and pressed with stone or wood. The plastic film is opened by the pile of the ear, so that the buds on the ear are leaked externally; the film is not removed during the growing season. Remove the weeds that grow from the hole at any time from June to September. 7-8 months to kill the stem and leaf pests. In early November, seedlings were exhumed and the plants were planted. If you do not plan to raise seedlings, you should fill the surface with winter water.
2 tender shoot cutting seedlings
2.1 Preparation of the slotting machine The bed is made of long-width-height (20.00~25.00)m1.10m0.12m in the north-south direction, surrounded by bricks or 1cm-thick wood boards and fixed firmly. The river sand is filled with 10~12cm in thickness.
2.2 Cutting Acquisition and Treatment
From early July to early August, semi-lignified shoots with a thickness of 0.3 cm or more were cut. The cuttings were cut at a length of 7 to 8 cm, and each section had two sections. The upper section had leaves remaining on the leaves, and the lower section had leaves removed. According to the 25~50 spikes and piers, the base extends into 25~40mg/L indole acid solution for 12~24h.
2.3 Cutting and post-insertion management According to the panicle spacing of 6~8cm, the cuttings are inserted into the sand and the cutting depth is 4~5cm. Insert a stick at the edge of the bed and cover the stick with a transmittance of 40%~50%. Shade net. Spray water on the net cloth, spray water once every 40~50min at 8:00-16:00 on sunny days, and spray water once every 60~70min on cloudy days. More water. After 25 to 30 days of cutting, the rooting condition of the cutting pine seedlings was investigated. When the amount of rooting reached 3 to 4 and the length reached 5 to 6 cm, the net could be removed. During weaving the net, weeds should be removed in time if there are weeds on the bed, and grass should be kept on the bed after the net is removed. After removing the net, do not spray too much water on the surface of the bed and keep the bed dry.
In early November, the seedlings will be sprayed out or sprayed on the bed once a winter to prevent drought. In winter, there is little snow and no snow area. It is best to cover the bed with 8~10cm straw.
3 Sowing seedlings
3.1 Fruit picking and storage
From November to January of the following year, the berries are picked, laid on the concrete floor, and pedaled to separate the pulp from the seeds. Sheng in the barrel, repeatedly adding water to panning, pouring out the flesh, peels and pods, remove the seeds of the sink, put it in the shade and dry for 7 to 10 days, and store it in a sand bag.
3.2 Selecting and Making Beds
In mid-to-late April, the flat sandy loam soil was selected, and the manure was spread on the surface, turning the soil 15-20 cm deep, and made a high bed with a width, height, and length of 1.20m0.15m (10.00-20.00) m.
3.3 One day before planting sowing, the seeds were soaked in warm water of 30~40°C for 24 h. One ditch of 2 cm in depth was drilled every 20~25 cm along the bed, and the seeds were sprinkled into the ditch. The seed distance was 2~3 cm. 1cm, sowing rate 2~3g/m2.
3.4 Post-broadcast management Table bed laying 1.0~1.5cm thick rice husk or peat soil. Water was sprayed on the cover, and the seedlings were not less than 8cm.8~10d after soaking on the surface of the bed. The seedlings were basically flush after 20 days. The bed humidity should be maintained before and after emergence. In June-September, the bed is pulled or shoveled every 15 to 20 days to loosen the bed without grass damage. During the growing season, aphids and caterpillars were infested, and 2.5% of deltamethrin was sprayed in time to kill.
Gold and Silver Lonicerae Seedling Technology
Loniceraruprechtiana Regel, deciduous shrub, plant height 3 ~ 4m, crown width 2.5 ~ 3.0m. Leaf oblong to oblanceolate to oblanceolate. Corolla lip, white and yellow. After the leaves fell at the end of October, the red berries were kept on the tree for 3 months. The white flowers are dazzling in the summer, and the red and green leaves are in autumn. The red fruits in winter are lining with the snow on the ground. Solitary planting, clumping planting, planting in the courtyard, attractions, and viewing effects are excellent. The plants are extremely resistant to cold, and as winter fruit plants, they are used more and more in the cold northern regions. At present, there are three kinds of seedlings, including hardwood cuttings, tender cuttings, and sowing. The three methods of biological control of L. caterpillars have their own characteristics. The hardwood cuttings are large and rooted, but the rooting rate is only about 75%; the rooting rate of tender cuttings is as high as 90%, but the roots are relatively few and the short ones are small. Sowing seedlings, large seedlings, more developed roots, but the seedlings are smaller. The three methods are summarized below for reference.
