Embodiment 1

[0016] 1) Seedling selection, in the early summer season, take one to two-year-old young shoots, cut into 30cm long cuttings, each section contains 3 nodes;

[0017] 2) Soil quality selection: choose sandy loam soil with loose soil quality. In the early stage of cutting, cut the lower end of the cutting seedlings near the joints into a slope, and make one bundle for every 40 roots. When preparing cuttings, it is strictly necessary to ensure that the cuttings do not wilt; the row spacing of the pricking plants is 5cm×10cm; after the cuttings, spray water frequently at the initial stage to keep the soil moisture at 50-60%; after the callus is produced, keep the soil moisture moist; Spray water once every 30 minutes, subject to the formation of water film on the leaves, keep moist 55%; after a large number of roots, gradually increase the light;

[0018] 3) Fertilization and sterilization: After 70% of the cutting seedlings take root, spray a 0.5% foliage fertilizer every five da...

Embodiment 2

[0021] 1) Seedling selection, in the early summer season, take one to two-year-old young shoots, cut into 30cm long cuttings, each section contains 4 nodes;

[0022] 2) Soil quality selection: choose sandy loam soil with loose soil quality. In the early stage of cutting, cut the lower end of the cutting seedlings near the nodes into a slope, and make a bundle of 40 roots. Soak the lower end of the cuttings with indole butyric acid (IBA) solution for 10 minutes, and dry the medicine. After the liquid is ready for cutting, it should be strictly guaranteed that the cuttings will not wilt; the row spacing of the holed plants is 5cm×10cm, and the water should be sprayed frequently at the initial stage after cutting to keep the soil moisture at 60%; after the callus is produced, keep the soil moisture moist; after rooting, Spray water once every 20 minutes, subject to the formation of water film on the leaves, keep moist 65%; after a large number of roots, gradually increase the ligh...

Embodiment 3

[0026] 1) Seedling selection, in the early summer season, take one to two-year-old young shoots, cut into 30cm long cuttings, each section contains 3 nodes;

[0027] 2) Soil quality selection: choose sandy loam soil with loose soil quality. In the early stage of cutting, cut the lower end of the cutting seedlings near the joints into a slope, and make one bundle for every 40 roots. Soak the base of the lower end of the cuttings with 500 mg / kg rooting powder solution for 10 minutes, and dry the liquid medicine. In preparation for cutting, it is strictly necessary to ensure that the cuttings do not wilt; after cutting, spray water frequently at the initial stage to keep the soil moisture at 60%; Form a water film as the standard, keep it moist at 65%; after a large number of roots have taken root, gradually increase the light; the row spacing of the hole-piercing plants is 5cm×10cm, insert 2 / 3 of the cuttings into the holes, water them after burying, and take root and germinate i...

Abstract

The invention discloses a method for improving the survival rate of forsythia cuttings, including 1) seedling selection, 2) soil quality selection, 3) fertilizer supplementation and sterilization, and 4) temperature control. In terms of water control, regular spraying and moisturizing are required to ensure cutting branches No wilting, after the seedlings are cut, maintain high temperature and humidity, and timely and proper disinfection measures prevent the cutting seedlings from being attacked by diseases and insect pests, ensure the good development of the seedling root system, rapid reproduction, and avoid the occurrence of less roots, root loss, aging, and disease susceptibility, etc. defect.

Description

technical field [0001] The invention belongs to the technical field of forestry cultivation, and in particular relates to a method for improving the survival rate of forsythia twig cutting seedling raising. Background technique [0002] Cuttings, also known as cuttings, are a common propagation method for cultivating plants. You can cut the stems, leaves, roots, buds, etc. of certain plants, or insert them into the soil, sand, or soak them in water, and wait until they take root. Planting to make it an independent new plant. In agricultural and forestry production, different plants have different requirements for cutting conditions. Only by understanding and adapting to the needs of different plants can a higher reproductive success rate be obtained. The cultivation method after cuttings plays a key role in the survival rate of cutting seedlings. The time from cuttings to rooting is as long as about one month, and the cultivation and management workload is heavy. , a little...
