How to improve the planting benefit of Lamei tree?

Chinese plum tree, alias yellow plum blossom, fragrant plum blossom, fragrant plum, dried plum, Chimonanthus genus of Chimonanthus family. The receptacle of the tree is sublignified, jar-shaped or Obovate-elliptic, long 2~5cm, 1~2.5cm in diameter, mouth contracted, and has a subulate lanceolate hairy attachment. Seeds (achenes) oval, chestnut brown. The surface is smooth and shiny. The flowering period is from November to February of the following year, the fruit period is from April to November, the plant height is 3m, the single leaf is opposite, the outer whorl of perianth is waxy yellow, the middle whorl has purple stripes, has strong fragrance, likes light, is slightly shade-tolerant, cold-resistant, should be planted in leeward and sunny place, likes sandy loam with good drainage, drought resistance, strong growth potential, strong branching ability and long life span, and is produced in northwest Hubei and Hanzhong region of Shaanxi Province.

The existing cultivation methods of Prunus mume mainly include sowing, grafting, cutting propagation, sowing, grafting, striping and cutting. the growth rate of the tree is slow, the survival rate is only less than 90%, and the management process is tedious, labor-consuming and time-consuming, and the economic benefit is low.

1. Before and after Cold Dew was planted separately, 50% phoxim or 50% fenitrothion 1000 times solution was sprayed to kill insects in the plum orchard. The Winter Solstice selected the 3-year-old plum tree as the mother plant, sawed off all the main branches at the height above the ground 50cm, and irrigated the whole orchard with overwintering water. In the following year, Rain Water dug semicircular potholes with a diameter of 60cm from the lower side of the root until half of the roots were exposed. From the clump of the mother plant, the main branch of the son root in the center of the mother plant continued to grow, and the separated sub-trees had more roots. The separated trees were planted with a distance of 5m and 4m.

two。 In the third year, around the Qingming Festival, 50% phoxim or 50% fenitrothion 1000 times solution was sprayed on the wax plum orchard to kill insects. Before and after the Beginning of Winter, the robust branches of 1-year-old seedlings were selected for trunk culture, and the 70cm was truncated, and a bud opposite to the lower interface bud was left under the cut mouth as the trunk to prolong the branch, and the rest of the branch from the cut mouth was strong and weak and used as auxiliary branches. In order to prevent the lower side branches from growing too vigorously and not competing with the central branch, two pairs of side branches under the cut buds must be cut off, and the left side branches were only used as auxiliary branches. Within the range of three main branches from the trunk 30cm, select one oblique branch to cut off the head, and leave one side bud as the side branch. Next year, the number of flowering branches of Lamei increased significantly [Jishan Huayao].
