Problems solved by technology

False magpie kidney tree is a tall tree with a fruiting period of 5-12 months. When the seeds mature, they will pop up naturally and scatter to the ground. The seed maturity time is inconsistent, and the uniformity of seedling emergence during production is poor. It has certain advantages for large-scale propagation and artificial cultivation The restrictive effect of

Embodiment 1

[0033] At the end of September 2016, the fresh seeds of False magpie kidney tree will be collected from the wild, and after a week of dark indoor germination at 28-30 ℃, they will be sown on a sterilized sand bed, and the seeds will be covered with river sand, with a thickness of about 2 cm. Keep the sand bed moist (about 65%) during the cultivation period. After three weeks of cultivation, the plant height of the seedlings reaches about 10 cm. At this time, the main root is well developed and there are 4-8 lateral roots. Transplant the seedlings with 2-4 true leaves into the substrate with mountain soil and organic fertilizer (10:1, volume ratio), cut off 3 / 4 of the leaves, arrange them neatly in the nursery (60% natural light), water enough Root water. Then water regularly to keep the substrate moist. After 2-3 months of hardening in the nursery, the seedlings can emerge from the nursery, and the rate of emergence from the nursery is over 98%.

Embodiment 2

[0035] In mid-October 2016, the collected mature seeds and river sand were put into bamboo baskets according to the volume ratio (1:4), watered thoroughly and placed in a room at 25°C for a week of germination treatment. During the germination period, the humidity was kept at 60 %about. After the germination is finished, the seeds are sown on-demand on the sand bed that has been treated with 600ppm carbendazim, and covered with river sand with a thickness of about 2 cm. Keep the sand bed moist (about 65%) during the cultivation period. After three weeks of cultivation, the plant height of the seedlings reaches about 10 cm. At this time, the main root is well developed and there are 3-6 lateral roots. Transplant the seedlings with 2-4 true leaves into the substrate with mountain soil and organic fertilizer (10:1, volume ratio), cut off 3 / 4 of the leaves, arrange them neatly in the nursery (60% natural light), water enough Root water. Then water regularly to keep the substrat...

Embodiment 3

[0037] In mid-October 2016, the collected mature seeds were packed in air-permeable cotton bags and stored at 4°C in low temperature and dark conditions; at the end of March 2017, the seeds of False magpie kidney tree preserved at low temperature were taken out and soaked in water , let the seeds fully absorb water; then put them in a breathable cotton bag and put them in a dark condition of 25°C for germination treatment, sow them on a sterilized sand bed 10 days later, cover the seeds with river sand, the thickness is about 2 cm, and cultivate them Keep the sand bed moist (about 65%) during this period. After three weeks of cultivation, the plant height of the seedlings reaches about 10 cm. At this time, the main root is well developed, and there are 4-8 lateral roots, and the seed emergence rate reaches more than 90%. Transplant the seedlings with 2-4 true leaves into the substrate with mountain soil and organic fertilizer (10:1, volume ratio), cut off 3 / 4 of the leaves, ar...

Abstract

The invention discloses a streblus indicus seedling propagation method. The streblus indicus seedling propagation method comprises the steps of seed collection, seed preprocessing, seed sowing, cultivation management and outplanting, wherein specifically, mature streblus indicus seeds are collected, mildew, damaged and verminous seeds are removed, then, bud forcing treatment is performed, 8-12 d before seed sowing, a cultivation groove is manufactured, the cultivation groove is filled with river sand with the granularity being 1-5 mm to obtain a sand bed, a carbendazim solution is used for atomizing the sand bed, a plastic film is used for closing the sand bed for sterilize and disinfect soil, a film is uncovered after 7-10 d, and seeds can be sown; the preprocessed streblus indicus seeds are moved to the sand bed for culture; 20-30 d after culture, the seeds can be transplanted into a nutrient bag for culture seedling hardening, and outplanting is performed after 2-3 months. By adopting the special germination method, on the basis of the specific seedling hardening and then outplanting, the germination rate and the final sprout outplanting rate reach 98% or above, the requirement for large-scale streblus indicus propagation and artificial cultivation is ensured, and economic benefits are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of planting, and in particular relates to a method for propagating seedlings of a false magpie kidney tree. Background technique [0002] False magpie kidney tree (Streblus indica Bur.) is a perennial tree of the Moraceae genus Streblus indica Bur. It is mainly distributed in Yunnan, Guangxi, and Hainan. Its medicinal part is the bark, which has the effect of treating traumatic bleeding, bruises, and gastrointestinal bleeding. Because of its remarkable effect, it is called "hemostatic bark". However, due to the destruction of its growth environment and unreasonable harvesting, its wild resources have been continuously reduced and exhausted. However, there is no relevant report about the seedling propagation and artificial cultivation of False magpie kidney tree. Therefore, the artificial propagation of False magpie kidney tree seedlings is of great significance to species protection, artificial cultivation...
