Embodiment 1

[0022] (1) Nursery land selection and site preparation: In 2011, in accordance with the Environmental Quality of Green Food Production Areas (NY / T391), 10 mu of sandy loam soil developed from purple shale was selected to establish an ear picking nursery base in Damiaochang Village, Xinglong Town, Meitan County . At the end of February 2012, the nursery was plowed to a depth of more than 50 cm after all the weeds were removed, leveled and raked finely, and the soil particle size was ≤ 1 cm.

[0023] (2) Sowing green manure: sowing Trifolium baifolium at the beginning of March 2012, 5kg per mu. Before sowing, soak the seeds in warm water at 30°C to 35°C for 2 hours, drain the water and spread them in the air for 10 hours, mix the seeds with plant ash at a mass ratio of 1:1, and then sow. After pulling out weeds in June and September, the coverage of Trifolium baiflora can reach 50%.

[0024] (3) Dig holes and apply base fertilizer: in October 2012, according to the plant spaci...

Embodiment 2

[0032] (1) Nursery land selection and site preparation: In 2012, in accordance with the "Green Food Origin Environmental Quality" (NY / T391), 150 mu of sandy loam soil developed with metamorphic rocks was selected to establish a raw material base in Tiewa Village, Huangjiaba Town, Meitan County. At the end of February 2013, the nursery was plowed to a depth of more than 50 cm after all weeds were removed, leveled and raked finely, and the soil particle size was ≤ 1 cm.

[0033](2) Sowing green manure: Sowing Trifolium cloverleaf at the beginning of March 2013, 5kg per mu. Before sowing, soak the seeds in warm water at 30°C to 35°C for 2 hours, drain the water and spread them in the air for 10 hours, mix the seeds with plant ash at a mass ratio of 1:1, and then sow. After pulling out weeds in June and September, the coverage of Trifolium baiflora reached 60%.

[0034] (3) Dig holes and apply base fertilizer: In October 2013, dig holes according to the density of plant spacing 1...

Abstract

The invention relates to a green and highly-efficient cultivation method for cutting seedlings of Litsea coreana. The method comprises the following seven technical steps: (1) nursery land selection and soil preparation; (2) sowing of green manure; (3) digging of holes and application of a base fertilizer; (4) outplanting of seedlings from a seedling nursery; (5) transplanting of cutting seedlings; (6) seedling management; and (7) pruning and shaping. According to the invention, a measure of planting the green manure is adopted after soil preparation, so costs of weeding and tending managementare reduced; roots are dipped with yellow mud prepared by adopting a water-retaining agent, a rooting agent and the like when the cutting seedlings are taken out of the seedling nursery, so the survival rate of transplanting is improved; and a rooting promotion fertilizer prepared by adopting an EM microbial agent and a rooting agent GGR in a seedling transplanting period and a seedling hardeningperiod is used to promote the growth of seedlings. The method provided by the invention can provide a reliable technical support for construction of a high-quality raw material base of the Litsea coreana, can guarantee the transplanting survival rate of the cutting seedlings to be 90% or above, can realize harvesting and utilization of the Litsea coreana in 5 years after transplanting and planting, can stabilize the output value per mu to 6000 yuan or more, and is applicable to production and cultivation of the green and high-quality raw material of the Litsea coreana.

Description

technical field [0001] The present invention relates to the breeding of trees, and furthermore, relates to a cultivation method of eagle tea cutting seedlings. technical background [0002] The processing and utilization of Eagle Tea has a history of more than 500 years, and the drinking area has reached more than 50 counties (cities) in 7 provinces (regions), mainly in the hot and humid areas in Dalou Mountain and Chishui River Basin in Guizhou Province in summer. It is a well-known traditional herbal tea in these areas for its unique effects of dispelling swelling, relieving heat and quenching thirst.
