High pressure propagation of Magnolia mandshurica
1. Articles to be used: culture soil (according to volume ratio, the ratio of vegetable garden soil, moss and old bran ash is 1: 0.5: 1, mix well with water, knead into a ball by hand, slightly show watermark, but not drip); branch scissors; grafting knife; plastic film (30 cm long, 25 cm wide); small brown rope, etc.
two。 Mother tree selection: select adult trees with a height of 160-200 cm (easy to operate), strong growth and dense branches.
3. Pressing time: the most suitable time is from early April to early May. At this time, the sap flows vigorously and is easy to peel, which is conducive to wound healing and rooting.
4. Striping method: first, select the 2-3-year-old branch in the dense part of the crown branch, 0.8-1 cm in diameter, peel around 10-15 cm from the base of the branch, 2-3 cm in width, and scrape off the cambium to prevent the cortex from healing again. Bandaging is carried out step by step, first tie up the plastic film with a string at the lower part of the wound, then roll it upwards into a cylinder, then fill in the prepared culture soil until the upper end of the peeling place is 6-8 cm, squeeze it out of the film with your hands to make it into a spinning shape, finally tie it up, and tie it properly around the periphery of the soil mass.
5. Lower tree management: the roots can be rooted half a month after striping, and the roots can be seen outside the film for all the surviving seedlings. Go down the tree from June to September, transplant with soil masses, and pour enough water on the roots. In the future, we should pay attention to drought prevention irrigation and apply rarefied organic fertilizer at the same time, which can be planted in late 10 days.

Cultivation of Magnolia paniculata
Cymbidium is an evergreen herb of Liliaceae, with clumps of plants, fleshy short rhizomes, slender leaves, striped lanceolate, bright green, with broad yellow-white longitudinal stripes in the middle; racemes terminal, florets white. The golden orchid likes the warm and humid semi-overcast environment, is not resistant to cold, and is afraid of being exposed to the hot sun. When it is hot in summer, it should be kept under the shade or in the shade. Daily cultivation should keep the basin soil moist without stagnant water, and create a small environment with moist air. Apply mature dilute liquid fertilizer or compound fertilizer every 20 days or so during the growing period.

Packaging of cut chrysanthemum
Cut chrysanthemum can usually be sent directly to the flower market without packaging in the case of short transportation distance or less transportation, but long-distance transportation, especially transnational cut flower export, must be packed. Cut chrysanthemum can usually be sent directly to the flower market without packaging in the case of short transportation distance or less transportation, but long-distance transportation, especially transnational cut flower export, must be packed. The packaging of cut chrysanthemum follows the general principles of cut flower packaging: ① protects the product from mechanical damage.
