Technical Field

The invention belongs to the technical field of garden tree cultivation and fertilization, and particularly relates to a balanced fertilization method for landscaping goldenrain trees.

Background

Goldenrain tree (scientific name: Koelreuteria paniculata), alias: mu Luan, Koelreuteria paniculata, Sapindaceae, Koelreuteria. Is deciduous arbor or shrub; bark is thick, grey brown to grey black, and longitudinal splitting in old age; the skin hole is small, and the color is uncovered when the skin hole is dark; the small branch has wart points, and is crinkled with short, soft or hairless with the leaf axis and the leaf stalk. The tender leaves of the goldenrain tree in spring are mostly red leaves, the goldenrain tree in summer turns yellow in color, the fruit is purplish red, is similar to a lantern in shape and is very beautiful; the goldenrain tree has strong adaptability and obvious season, and is an ideal greening and foliage tree species. It is suitable for house tree, street tree and garden tree, and goldenrain tree is also good tree species for planting in industrial polluted area. The Koelreuteria paniculata is used as a shade tree, a street tree and a garden tree in spring, summer and autumn and winter, and also used as a greening tree species in residential areas, factory areas and villages. The goldenrain tree can be used to extract tannin extract, flower can be used as yellow dye, and seed can be used to extract oil. The wood is yellow-white, is easy to process and can be made into furniture; the leaves can be used as blue dye, the flowers can be used for medicine, and the leaves can also be used as yellow dye. The fruit contains sterol, saponin, flavonoid glycoside, anthocyanin, tannin and polyuronic acid. Saponin A and Saponin B are separated from the saponin. The dried seeds contain 9.4% of water, 17.5% of crude protein, 0.045% of lecithin phosphate, 7.0% of starch, 9.0% of ash and 20.9% of lipid. The kernel contains 38% of oil, and sterol and palmitic acid are separated after saponification. The leaf contains gallic acid methyl ester, and has inhibitory effect on various bacteria and fungi.

Goldenrain tree grows in calcium-based soil generated by limestone weathering, is cold-resistant, is only distributed in the yellow river basin and the downstream of the Yangtze river basin in China, is rare in the north of the sea river basin, and cannot grow in a laterite area with silicon-based acidity. Goldenrain tree germinates late in spring and leaves fall early in autumn, so that the growth period is short every year, the goldenrain tree grows slowly, wood can only be used for manufacturing small appliances, and seeds can be used for squeezing industrial oil.

Goldenrain tree is a plant which is pleased to light and slightly resistant to half shade; cold resistance; but the planting method is not resistant to flooding, pays attention to soil for planting, is drought-resistant and barren, has strong adaptability to the environment, is favored to grow in calcareous soil, and is resistant to salinization and short-term waterlogging. Koelreuteria paniculata has deep root, strong tillering capacity, moderate growth speed, slow growth of young trees, gradual growth later and strong smoke resistance. In the original area, particularly, xuchang 37154, most of the tombs are planted.

The wind resistance is strong, the low temperature of 25 ℃ below zero can be resisted, and the wind resistance has strong resistance to dust, sulfur dioxide and ozone. The high-altitude grains are mostly distributed in low mountains and plains with the altitude of 1500 meters or less, and the maximum altitude can reach 2600 meters.

Goldenrain tree, which can occupy october in one year. The branches and leaves of the tree are luxuriant and beautiful in spring, and the leaves are bright red and lovely; in summer, the leaves are gradually green, and the yellow flowers are full of trees, so that the leaves are resplendent and magnificent; in autumn, summer flowers fall out, and then capsule branches are full of, such as calyx seu fructus physalis, and are colorful. The excellent tree is a greening landscape tree of the top grade.

Goldenrain tree can be used as urban landscape tree, and goldenrain fruit can be used as Buddha bead, so temple is cultivated.

The goldenrain tree has less pest and disease damage, easy cultivation and management, deep cultivating soil and optimal moist soil. Mainly seeding and propagating, tillering or root cutting, and properly cutting the main root and the thick lateral root during transplanting, so that multiple fibrous roots can be promoted and survival is easy. Harvesting in autumn when the fruit is ripe, and timely drying and shelling. Because the seed coat is hard and not easy to permeate water, if the seed coat is not treated, the seed coat does not sprout in spring sowing in the next year, so the seed coat can be removed in autumn for sowing, and the seed coat can be laminated by wet sand for spring sowing. Because the trunk of the goldenrain tree is not easy to grow straight, stumping and trunk cutting are needed during the first transplantation, and fertilizer and water management is enhanced. Shoots are germinated from the base part in spring, and straight and robust plants are selected and cultured into trunks, so that the trunks grow quickly and are straight. The first cut-off can not meet the requirement, and the cut-off treatment can be carried out in the spring of the second year. Transplanting every 3 years, wherein the main root and the thick lateral root are cut off properly to promote new root. The young Koelreuteria paniculata trees grow slowly, and the dense planting is suitable for the first two times of transplantation, so that the straight main trunk can be cultured conveniently, and the land is saved. After that, the tree crown should be properly thinned and well cultivated.

Related technologies are mostly fertilization methods and cultivation methods for seedling raising and breeding. Due to different growth histories of plant varieties and different species of each family, a great deal of fertilization is mainly used for the transplanted tree varieties, and in addition, various treatment modes such as a large amount of acid rain in south China of Yangtze river and an acidic state of soil have great influence on the ecological environment due to the change of the environment.

The main scheme is a balanced fertilization method aiming at reducing the fertilization amount, reducing the soil acidity state, and improving the fertilization efficiency and the fertilizer absorption capacity.
