Problems solved by technology

[0004] The conventional method of raising guava seedlings is grafting, but the grafting method has a long cycle and low efficiency, and the resulting fruit has certain variability.
In the prior art, there are also methods of raising seedlings by cuttings, including hard branch cuttings and tender branch cuttings. Since

Embodiment 1

[0021] A. Selection of cuttings: On March 15, 2011, select semi-lignified new shoots of guava that year, with a cut length of 15 cm, keep 3 buds, keep the top leaves of the cuttings, cut the lower part of the cuttings into an inclined plane, and store them in moisture;

[0022] B. Cutting preparation: On May 11, 2011, the seedbed matrix was trimmed and paved. The matrix composition was a mixture of humus soil, sandy soil, fine river sand and peat soil, and the weight ratio was 1:2:3:1. Grooves are pressed out in the direction of the length of the seedbed, and the distance between the grooves is 10 cm. Along the direction of the grooves, small holes are inserted at equal intervals with rods of the same thickness as the cuttings. The depth of the holes is 10 cm; Indoleacetic acid was soaked for 2 hours and then taken out to dry;

[0023] C. Cutting: insert the cuttings into the small hole, bury until the upper part of the cuttings is slightly higher than the seedbed level, rinse...

Embodiment 2

[0027] A. Selection of cuttings: On April 2, 2012, select semi-lignified new shoots of guava that year, with a cut length of 18 cm, keep 3 buds, keep the top leaves of the cuttings, cut the lower part of the cuttings into an inclined plane, and then store them in moisture;

[0028] B. Cutting preparation: On May 25, 2012, the seedbed matrix was trimmed and paved. The matrix composition was a mixture of humus soil, sandy soil, fine river sand and peat soil, and the weight ratio was 1:2:3:1. Press out grooves in the direction of the length of the seedbed. The distance between the grooves is 12cm. Along the direction of the grooves, use rods of the same thickness as the cuttings to insert small holes at equal intervals. The depth of the holes is 12cm; put the lower part of the cuttings into 1500mg / L Indoleacetic acid was soaked for 3 hours and then taken out to dry;

[0029] C. Cutting: insert the cuttings into the small hole, bury until the top of the cuttings is slightly higher...

Embodiment 3

[0033] A. Selection of cuttings: On April 25, 2013, select semi-lignified new shoots of guava in that year, with a cut length of 20 cm, keep 4 buds, keep the top leaves of the cuttings, cut the lower part of the cuttings into an inclined plane, and then store them in moisture;

[0034] B. Cutting preparation: On June 20, 2013, the seedbed matrix was trimmed and paved. The matrix composition was a mixture of humus soil, sandy soil, fine river sand and peat soil, and the weight ratio was 1:2:3:1. Press out grooves in the length direction of the seedbed, and the distance between the grooves is 15cm. Along the direction of the grooves, use sticks of the same thickness as the cuttings to insert small holes at equal intervals. The hole depth is 15cm; put the lower part of the cuttings into 1000mg / L ind Indoleacetic acid was soaked for 4 hours and then taken out to dry;

[0035] C. Cutting: Insert the cuttings into the small hole, bury until the top of the cuttings is slightly higher...

Abstract

The invention provides a guava cutting seedling-raising method comprising the steps of A, cutting slip selection, B, cutting preparation, C, cutting, and D, cutting post treatment. According to the invention, half-lignified softwood branches are adopted as cutting slips. Compared with that adopting hardwood branches, a rooting rate is improved. Before cutting insertion, the lower ends of the cutting slips are soaked by a growth regulator. After the cutting slips are inserted into a seedbed, the growth regulator is added in the medium around the cutting slips. With the effects and influences of the two applications of the growth regulators on the lower ends of the cutting slips, the cutting slip activity and the rooting rate can be greatly improved. Water mist is sprayed intermittently to the cutting slips, such that humidity in the sunshade shed can be effectively maintained, and cutting slip rooting can be promoted. The seedbed is subjected to a heating treatment, such that the influence of diurnal temperature difference on the cutting slips can be prevented, and a normal cutting slip rooting environment is ensured. In summary, the cutting method provided by the invention has the advantages of simple steps, convenient management, short period, and high survival rate. With the method, a large amount of seedlings can be cultivated within a short period of time.

Description

technical field [0001] The invention relates to the field of plant cutting propagation, in particular to a guava cutting seedling raising method. Background technique [0002] Guava belongs to the evergreen small trees of Myrtaceae, 2-5m high. It is native to tropical America and was introduced to China in the 16th to 17th centuries. It is now cultivated in Taiwan, Guangdong, Guangxi and Fujian in southern my country, among which Taiwan and Guangxi and Guangdong are the most common. Ripe fruit is pale yellow, fleshy, juicy, juicy, fragrant and sweet. [0003] Guava likes light, likes warmth, is not cold-resistant, and likes fertile, well-drained soil; guava can be grown by seedlings, ring branches (air layering) and grafting. Since the root system can produce root tillers, it can also be used by branching. The guava has a well-developed root system, is resistant to barrenness, has a very high survival rate and a very fast growth rate. The guava seedlings sown in the same y...
