Ankang, Shaanxi Province, known as "Bashan Daughter Red", is a woody plant of Rosaceae and Photinia. It is an evergreen tree and likes warm and humid climate. Cold resistance is not strong, but also resistant to shade. The requirements for soil are not strict. Mainly produced in the Yangtze River basin and south of Qinling Mountains, with a small amount of cultivation in North China. Rich in ornamental value, can also be used as medicine. The flowering period is from May to July, and the fruiting period is 65438+1October.

Management and maintenance

Seedling management

When the saplings are basically in full bloom (about 30 days), the grass should be carefully pulled out to prevent the saplings from being pulled out. Should the density of saplings be too high?

Interplanting in time, transplanting or replanting in time in May if the density is too small. According to the row spacing of 20 cm× 20 cm, plant seedlings and water them to ensure high survival rate. Urea or ternary compound fertilizer 1 time every half month, and the dosage per mu is about 4 kg. Irrigation in time during drought and drainage in time during flood. The common diseases and insect pests in seedbed stage include damping-off disease, damping-off disease, grubs and cutworms, which should be prevented in time. It is also necessary to prevent birds and animals from harming saplings. ?

Post-insertion management

After cutting 1 week, the water content of the substrate should be controlled at 60%~70%, and the relative humidity of the air should be 95%. After cutting 15 days, most cuttings began to take root. The moisture content of the substrate should be controlled at about 40%, and the film should be gradually uncovered for ventilation. When more than 50% cuttings germinate new leaves, the film can be uncovered. Spraying 1 bifofur zinc and carbendazim for 800 times every 20 days to control anthracnose and root rot, promptly pulling out diseased plants and burning them. After all cuttings take root and spread leaves, spray water-soluble chemical fertilizer (0.2% urea) to promote growth. ?

Water and fertilizer management

Apply sufficient base fertilizer before planting and water it in time after planting. Pay attention to watering during the growth period, especially in the high temperature season from June to August, and it is appropriate to water 1 time for half a month. A certain amount of Trim compound fertilizer and organic fertilizer can be topdressing in spring and summer. ?

be cold-proof

The newly transplanted heather must pay attention to cold protection for 2-3 years. After winter, build a strong windbreak wall and leave an opening in the south to let the sun shine in. In addition, cover the ground with a layer of straw or other mulch to prevent the roots from freezing. ?

decrease

When pruning heather, plants with many and thin branches should be pruned vigorously to remove some branches; Light pruning of plants with few and thick branches can promote more germination of flower branches. If the crown is small, cut short the annual branches to enlarge the crown; If the crown is large, the main branches will retract, and the main branches will be replaced by side branches, which will relieve the tree. If heather grows vigorously, cut off long branches after flowering to promote the growth of leaf buds. In winter, for the purpose of plastic surgery, some dense branches and useless branches are thinned out to maintain the growth space and promote the development of new branches. Tree species used for modeling should be pruned 1-2 times a year. If they are used as hedges, they should be pruned frequently to keep a good shape.
