Embodiment 1
[0025] The method of cutting podocarpus in summer includes: building a nursery greenhouse: building a nursery and a shade greenhouse before cutting the Podocarpus pine; selecting sandy loam soil with good drainage as a nursery, deep plowing the soil of the nursery, and building a 7-10m long, 8-8- 12cm, the width of the upper bottom is 60-80cm, and the width of the lower bottom is 70-90cm. The furrows between the strips are 5-10cm for drainage, and the surface of the nursery soil is covered with small pebbles with a diameter of 5-7cm to facilitate drainage. and reduce water evaporation; build a plastic greenhouse outside the nursery with a height of 3.2-3.5m to ensure ventilation and shade;
[0026] Soil substrate treatment: Taking advantage of the high temperature in summer, the seedbed soil used for cuttings in nutrient bowls needs to be exposed to the sun for 48 hours in summer for sterilization treatment. During the exposure period, the soil needs to be turned 1-2 times; the...

[0034] Fertilization: When the soil is packed in a nutrient bowl, apply 4g of pure N per kilogram of soil, P 2 o 5 5g,K 2 The ratio of 0.3.5g fertilizes, and mixes with soil and fills the bowl, and embeds the humus soil of 0.5kg at the center position of the nutrient bowl, and other steps are with embodiment 1.
Embodiment 3
[0036] Fertilization: When the soil is filled with a nutrient bowl, 3.0g of pure N is applied per kilogram of soil, and P 2 o 5 3.0g, K 2 O 3.0g ratio fertilization, and mix with soil adornment, bury the humus soil of 0.5kg in the nutrient bowl central position, other steps are with embodiment 1.

Abstract
A summer cuttage Podocarpus macrophyllus method comprises the following steps: building a nursery greenhouse; processing soil matrix: using the summer high temperature to expose the seedbed soil for nursery pot cuttage for 48 hours for sterilization, and turning the soil for 1-2 times in the exposure period; using a 4mm sieve to sieve the exposed soil, and loading the soil into the nursery pots; fertilization: applying pure N 4-5g, P2O5 2.5-5g and K2O 2.0-3.5g in per kg of soil when the soil is loaded in pots, evenly mixing with the soil, and loading the pots; gathering cutting slips; refrigerating and moisturing same; rooting; carrying out cuttage; anaphase management; seedling for sell. The method uses the summer high temperature to expose and sterilize the seedbed soil, and applies thebase fertilizer, thus well solving the problems that an existing Podocarpus macrophyllus seedling growing planting technology is limited by seasons, and developing the Podocarpus macrophyllus cuttagetechnology under summer high temperature conditions. the Podocarpus macrophyllus cuttage survival rate can reach 82% or above.
Description
technical field [0001] The invention relates to a method for cutting Podocarpus pine in summer, and belongs to the technical field of tree planting. Background technique [0002] Podocarpus is a kind of pine tree, also known as Luohanshan, evergreen Luohanshan, soil fir, money pine, cypress, Luohancypress, Jiangnan cypress. It is an evergreen tree, which can be as high as 18 meters. It is usually pruned to keep it low. , the leaves are alternate, arranged in a spiral shape, also divided into male and female, the seed receptacle is larger than the seed, the seed receptacle is red when mature, and with green seeds, it looks like a bald monk wearing a red monk robe, hence the name Podocarpus pine. Podocarpus pine is produced in Jiangsu, Zhejiang, Fujian, Anhui, Jiangxi, Hunan, Sichuan, Yunnan, Guizhou, Guangxi, Guangdong and other provinces, and is cultivated in all provinces south of the Yangtze River. Because potted Podocarpus is available for viewing, its wood is used for c...
