Embodiment 1

[0017] The matrix formula is: mix 80%wt Northeast peat and 20%wt Inner Mongolia weathered coal and stack it for 2 weeks, then mix it with perlite at a volume ratio of 9:1, add water and stir evenly, until it is kneaded into a ball without dripping and falls to the ground. Serve on a plate when spread. Gently scrape and compact with a scraper, ready for cutting.

[0018] The full-light spraying method is used for seedling cultivation, supplemented by plant hormones that promote the rooting of Caigui cuttings: select Caigui with vigorous growth as the mother tree, and cut the lignified or semi Lignified branches. The length is 6-8 cm, and the young shoots are cut off, leaving 4 leaves at the top. If the cuttings are tender and small, at least 2 bud nodes should be left, and the incision should be cut about 0.5 cm below the node position of the lowest bud node at the end of the cutting. The upper end is cut into a flat mouth, and the base is cut into an inclined plane. The bas...

Embodiment 2

[0020] Referring to Example 1, the main difference is that 80%wt Northeast peat and 20%wt Inner Mongolia weathered coal (according to mass fraction) were mixed and stacked for 2 weeks, then mixed with perlite at a volume ratio of 7:3, added water and stirred evenly, When it reaches the state of being kneaded into a ball without dripping and falling to the ground, put it on a plate. Gently scrape and compact with a scraper, ready for cutting. The bases of the cut cassava cuttings were treated with 50, 100, and 200 mg / L of GGR, 6-BA, and IBA respectively for 2 hours, and then the cuttings were cut, and the seedlings were raised by spraying under full light. The rooting rate reached 64-82% after 40 days, and over 95% after 60 days.

Embodiment 3

[0022] Referring to Example 1, the main difference is that 80%wt Northeast peat and 20%wt Inner Mongolia weathered coal (according to mass fraction) were mixed and stacked for 2 weeks, then mixed with perlite at a volume ratio of 5:5, added water and stirred evenly, When it reaches the state of being kneaded into a ball without dripping and falling to the ground, put it on a plate. Gently scrape and compact with a scraper, ready for cutting. The bases of the cut cassava cuttings were treated with 50, 100, and 200 mg / L of GGR, 6-BA, and IBA respectively for 2 hours, and then the cuttings were cut, and the seedlings were raised by spraying under full light. The rooting rate reached 60-83% after 40 days and over 95% after 60 days.

Abstract

Cai Gui cutting fast rooting and rooting matrix formula and its application consisting of organic nutrient soil and minerals. The organic nutritional soil is 80-90%WT peat and 10-20%WT weathered coal.25%WT, the organic matter of peat contains no less than 60%WT, the weathering coal contains not less than 40%, and the mineral is one or its mixture in perlite and vermiculite.The volume ratio of minerals is 9: 1-3: 7.After 40 days of cutting, the rooting rate of the matrix screwing screws can reach 40-83%, and the root system is covered with cuttings.

Description

technical field [0001] The invention relates to the field of agriculture and horticulture, and is specially aimed at the rapid propagation of cassia osmanthus seedlings, especially a plug matrix formula for rapid rooting of cassia osmanthus cuttings and its application. Background technique [0002] Caigui is an evergreen small tree or shrub of Oleaceae (Oleaceae). Most of Osmanthus plants are famous ornamental flowers and trees and excellent garden tree species in China. Osmanthus fragrans is one of the top ten famous flowers in China. It has good shape, color, fragrance and rhyme, and has high ornamental value. Yuntian Caigui is an evergreen small tree or shrub belonging to Oleaceae (Oleaceae). Its flowering characteristics are the same as that of ordinary osmanthus. The crown is oval, the bark is off-white, and the young branches are purple. The leaves are opposite, ovate or elliptical, the leaves are thicker and leathery, with obvious veins, and the petioles are yellow-...
