Embodiment 1
[0016] Example 1 Test in July, 2015
[0017] (1) Construction of nursery facilities: 180 square meters of simple greenhouses with a height of 2m, not covered with plastic film, only covered with shade nets with a shading rate of 75%; 4 seedbeds with a width of 100.0cm, a depth of 35cm, and a length of 28m are built in the greenhouse. Total area 112㎡
[0018] (2) Substrate treatment: 10 days before cutting, mix vermiculite and humus with a volume ratio of 2:1, put them into nutritional bags with specifications of 10cm (diameter) × 15cm (height), 100 pieces / ㎡, and then The concentration is 1500mg.L -1 The carbendazim was used for disinfection, and the humidity of the substrate was kept at 80%.
[0019] (3) Spike specifications: In mid-August 2015, 11,500 semi-lignified branches with a diameter of more than 0.3cm were collected in that year.
[0020] (4) Trim the cuttings: Harvest the cuttings before 10 am and place them in a cool and ventilated place. Start pruning the cutti...

Abstract
A tender branch cutting seedling raising method for kadsura coccinea comprises seven technical links of seedling raising facility construction, substrate treatment, scion selection, trimming of cuttings, soaking with a rooting agent, cutting, and shading for moisturizing. IBA is dissolved by using a potassium hydroxide strong alkali solution and NAA is dissolved by using a sodium hydroxide strongalkali solution, so as to form potassium salt and sodium salt dissolved in water, so that scion surface layer absorption is facilitated, therefore the rooting rate of the cuttings can be improved by 90% or above; and a low-concentration distilled water solution of the rooting agent is adopted for soaking, the whole cuttings can fully absorb the rooting agent, and the defects that the scions are not dipped in the rooting agent and the treatment time is long to generate phytotoxicity are overcome; a covering mode of a double-layer sunshade net and a small arched shed is adopted, so that the effects of shading and cooling are achieved, the humidity of the nursery land can be kept by natural rainfall, and manual watering is not needed after cutting, the management cost is reduced, and the rooting rate of the cuttings is improved. According to the method, the streamlined operation can be realized, and a basis for the standardized field cutting seedling raising technology of the semi-lignified branches of the kadsura coccinea can be provided.
Description
technical field [0001] The invention relates to a crop cultivation technique, in particular to a method for growing seedlings of cold rice balls by twig cuttings. Background technique [0002] Schisandraceae plants have high medicinal value, such as Schisandra ( Schisandra chinensis ), commonly known as Schisandra chinensis, mainly treats neurasthenia, cough and asthma due to lung deficiency, etc., and is a famous bulk medicinal material. Southern schisandra cold rice balls ( Kadsuracoccinea ), commonly known as "Big Blood Vine", has the effects of relaxing tendons and activating blood, dispelling wind and dampness, reducing swelling and relieving pain; the fruit is made of Yi nationality's health-preserving wine; cold rice ball stems, leaves, and fruits all contain triterpenoids and sterols Volatile oil, the oil content of dried fruit can reach 0.5%~1.0%, which is an excellent raw material plant for the development of health care products for high blood pressure; fresh f...
