Problems solved by technology

The sexual reproduction period of cycads is longer and the speed is slower. Plants over 10 years old can bloom, and seeds are difficult to obtain. Therefore, most of them are propagated by tillers at present, and the survival rate has increased. It is about 83%, which is still not very ideal.

Embodiment 1

[0020] A tillering propagation method of cycads, comprising the following steps:

[0021] (1) Tiller bud selection treatment: cut off the tiller buds on the 3-year-old cycad mother plant from the root connected to the mother plant with a knife, apply plant ash on the tiller bud wounds, and place the unrooted tiller buds in a cool and ventilated place Let it dry for 2 days and set aside;

[0022] (2) Accelerating the root: the unrooted tiller buds are planted in plain sand, and the depth when the tiller buds are planted is half of its height, watered 1 time after planting, and placed in indoor sunlight to see the light for maintenance;

[0023] (3) transplanting: when the new leaves that grow on the tiller buds are all rolled out by the curling shape, the tiller buds are transplanted in the cultivation soil, and the cultivation soil is composed of the following components by weight fraction: 40% humus, 18 %farmland soil, 14% mycorrhizal soil, 24% river sand, 4% calcium magnesi...

Embodiment 2

[0027] A tillering propagation method of cycads, comprising the following steps:

[0029] (2) Accelerating the root: the unrooted tiller buds are planted in plain sand, and the depth when the tiller buds are planted is half of its height, watered 1 time after planting, and placed in indoor sunlight to see the light for maintenance;

[0030] (3) transplanting: when the new leaves that grow on the tiller buds are all rolled out by the curling shape, the tiller buds are transplanted in the cultivation soil, and the cultivation soil is composed of the following components by weight fraction: 40% humus, 18 %farmland soil, 14% mycorrhizal soil, 24% river sand, 4% calcium magnesi...

Embodiment 3

[0034] A tillering propagation method of cycads, comprising the following steps:

[0035] (1) Tiller bud selection treatment: cut off the tiller buds on the 3-year-old cycad mother plant from the root connected to the mother plant with a knife, apply plant ash on the tiller bud wounds, and place the unrooted tiller buds in a cool and ventilated place Let it dry for 2 days and set aside;

[0036] (2) Accelerating the root: the unrooted tiller buds are planted in plain sand, and the depth when the tiller buds are planted is half of its height, watered 1 time after planting, and placed in indoor sunlight to see the light for maintenance;

Abstract

The invention provides a tillering reproduction method for a sago cycas. The tillering reproduction method for the sago cycas comprises the steps that (1) selecting and processing on a tiller bud are conducted, the tiller bud on a stock plant of the triennial sago cycas is cut off from the root portion connected with the stock plant, plant ash is smeared on the wound of the tiller bud, and the tiller bud which is not rooted is placed in a cool ventilated place to dry for two days as a standby; (2) root promoting is conducted, the tiller bud which is not rooted is planted into the pure sand, watering is conducted once after the planting, and maintaining is conducted in a room with lots of sunshine; (3) transplanting is conducted, the tiller bud is transplanted into the culture soil when the new leaves completely expand from curled leaves; (4) managing is conducted, and the tiller bud is placed in the sunshine when the new leaves appear; the culture soil is watered permeably once when the culture soil is dry, and water is sprayed on the leaves twice in the morning and evening everyday when the tiller bud grows fast; in the seeding stage, pancake fertilizer and water are applied once every two months, and leaf fertilizer is applied once every other month; the soil is replaced once every three years, and scrap iron is added in the soil when the oil replacing is conducted; (5) pest controlling is conducted. According to the tillering reproduction method for the sago cycas, the reproductive survive rate is high and the growth of the sago cycas is good.

Description

Technical field: [0001] The invention relates to a tillering propagation method of cycads. Background technique: [0002] Cycad, commonly known as iron tree, also known as Pihuo banana, Fengwei banana, Fengwei pine, Fengwei grass, Cycadaceae, cycad. One is named for its high wood density, which sinks in water and is as heavy as iron; the other is named for its growth requires a large amount of iron. It is now widely distributed in China, Japan, the Philippines, Indonesia and other countries. Cycas is most famous for its flowering, which is called "iron tree flowering". The cycad tree has a quaint shape, a strong trunk, as hard as iron, smooth and bright feathers and leaves, and is evergreen in all seasons, so it is a very beautiful ornamental tree species. The sexual reproduction period of cycads is longer and the speed is slower. Plants over 10 years old can bloom, and seeds are difficult to obtain. Therefore, most of them are propagated by tillers at present, and the sur...
