Embodiment 1

[0014] Embodiment 1, the concentration selection of rooting-promoting medicine

[0015] On September 26, 2010, the experiment was carried out with rooting medicine (ie rooting powder) of three concentrations (500PPm, 1000PPm, 1500PPm) made by ourselves, and the control without rooting medicine treatment, and 30 cuttings were cut for each concentration and control. Using the same management and protection measures, the survey was conducted on June 8, 2011, and only 5 strains survived in the end. Among them, 1 plant survived at 1000PPm, with a survival rate of about 3%; 4 plants survived at 1500PPm, with a survival rate of about 13%; neither 500PPm nor the control group took root and survived. Experiments and experience show that the concentration of 1500PPm is the best recommended concentration.

Embodiment 2

[0016] Embodiment 2, the impact of different cutting time on the survival rate of cutting seedlings

[0017] In the experiment, the treatment concentration of root-promoting drugs was 1500 PPm.

[0018] On April 26, 2011, 110 cuttings were cut with last year's branches (the new year's branches did not grow). After a period of time, the leaves of the cuttings turned yellow and fell off one after another, and none of them survived.

[0019] On May 31 and June 20, 20 cuttings were used to cut the cuttings of the current year's branches, and the survey was carried out on September 30. In May, 4 cuttings survived, with a survival rate of 20%; in June, 5 cuttings survived, with a survival rate of 25%.

[0020] On May 25th and June 25th, 2012, 50 cuttings were used to cut the cuttings of the current year's branches. The survey until September 17th showed that the survival rate of 23 cuttings survived in May was 46%; the survival rate of 27 cuttings survived in June was 54%. .

Embodiment 3

[0022] The selection of cutting seedling transplanting time after embodiment 3, cuttage surviving

[0023] On October 8, 2012, two batches of cuttings in May and June of this year were transplanted into 18 cm nutrient pots. On December 11, a total of 49 plants survived the two batches of transplanting, and the average survival rate of transplanting was 98. %. Among them, 23 live seedlings were transplanted in May, and 22 survived, with a transplant survival rate of nearly 96%; 27 live seedlings were transplanted in June, and 27 survived, with a transplant survival rate of 100%.

[0024] It can be seen that the survival rate of cuttings in May and June is relatively high, which can be used as the recommended cutting time. The higher survival rate of transplanting in October can be used as the recommended transplanting time.

[0025] Conclusion: At present, the best plan for cutting propagation of Nanchuan wood pineapple is as follows: the cuttings are selected from the curren...

Abstract

The invention discloses a cutting propagation method of Artocarpus nanchuanensis and belongs to the technical field of vegetative propagation. The method includes the steps of selection of cutting substrate, selection of cuttings, treatment of cuttings, selection of cuttage time, post-cuttage management, transplanting time selection and the like. The cuttage success rate already reaches 54%. The success in cutting propagation of Artocarpus nanchuanensis solves the problem that seedling demanded sources from plant market are few and meets the market demand for Artocarpus nanchuanensis seedlings. The number of species populations of Artocarpus nanchuanensis is increased, and ex-situ conservation is benefited. Superior character of fine stock plants is maintained by the vegetative propagation of the fine stock plants.

Description

technical field [0001] The invention belongs to the technical field of plant asexual propagation, and in particular relates to a cutting propagation method of Nanchuan wood pineapple. Background technique [0002] Nanchuan wood pineapple ( Artocarpus nanchuanensis S. S. Chang S. C. Tan et Z. Y. Liu), is a perennial tall tree of the genus Jackfruit in the family Moraceae. It is not only a unique species in Chongqing, but also a species of Jackfruit genus naturally distributed in the northernmost part of my country. It is one of the rarest endemic plants in China. The Nanchuan wood pineapple tree is tall and straight, with a beautiful posture. It can be planted alone, in a row, or in groups, all of which can create a good landscape and ecological effect. It is suitable for use as walkways, gardens, and ecological forests. The plant has strong growth potential, rapid forest formation, long growth life span, and all century-old trees can bear fruit normally. It is a very fine...
