How to plant Jin Guihua with high survival rate? (It's Miao. )
Spread 1. Cutting: Before sprouting in spring, cut the fully developed annual branches into a branch with a length of 5 cm- 10 cm, leave 2-3 leaves on the upper part, insert them into river sand or loess bed, shade them, or cut off the green branches that grew in that year after the new branches stop growing in summer, and cut them in the same way. 2. High pressure, selecting suitable thick branches from the mother tree in spring, cutting them from the lower side to the radius depth, bending the branches to the opposite side to make them split from the incision to 6 cm-9 cm long, then putting the split part into a clay pot, filling the soil, hanging the clay pot on the branches or replacing the clay pot with a plastic film, watering them frequently during the rooting process to keep the soil moist, and cutting them from the mother tree for reproduction after rooting in autumn. 3. Grafting: taking Ligustrum lucidum or Ligustrum lucidum as rootstock, cutting and grafting before germination in spring. When grafting, the rootstock should be cut off near the root, which is convenient for survival, but it can take root from the scion after survival, which can ensure high grafting survival rate and fast growth after survival. In the cold north, willow can be used as rootstock, which has strong cold resistance and twice the growth rate after survival.
When planting, choose a place with sufficient sunshine, good drainage and deep topsoil for planting. When planting, base fertilizer, compost or plant ash should be planted. When planting, carefully plant big seedlings with soil balls. When potted, the base fertilizer should be placed at the bottom of the pot, and the seedlings with soil balls should be carefully placed in the pot. You can put pots all year round, but in early spring, February and early winter, 10- 1. After survival, big trees are pruned once a year, and potted young trees are pruned 2-3 times a year. Available nitrogen fertilizer can be applied once a year before pruning or flowering, especially one month before flowering, and organic fertilizer (such as peanut cake and bone meal) can be applied once after flowering in winter as the base fertilizer for the coming year. After that, quick-acting nitrogen fertilizer was applied once a year in March, and phosphorus and potassium fertilizer were applied once a year in May and July, 10.
Osmanthus fragrans has fewer pests and diseases, such as leaf-eating pests such as thorn moths, bag moths and leafhoppers. Every April, 3000 times of water can be sprayed with dichlorvos emulsion and flower nutrient solution, and 300 times of water can be sprayed with omethoate and flower nutrient solution from July to August. Prevention is more important than treatment, and pesticides are sprayed in April, July and August every year when no pests are found. Spray it in time if there are pests and diseases, but spray it three times in a row, with an interval of 3 days each time.
