Quick propagating method of megranate

Abstract

The present invention discloses a guava quick propagation method which comprise the following steps: selecting daylight booth or green house of 70% transmittance, dipping cutting in rootage agent and inserting it to medium, keeping indoor relative humidity at 85%-100%, temperature at 25-40 degree, keeping indoor temperature at 25-35 degree after rooting, relative humidity at 75-85%, transplanting the cutting outside of green house for cultivation after the lateral root occur. The propagation rate is quick, rootage rate and transplanting survival rate is high in the present inventive method.

Description

technical field [0001] The invention belongs to the technical field of plant breeding and relates to a pomegranate breeding method. Background technique [0002] At present, my country's pomegranate production has been developing slowly for many years. The main reason is that the popularity rate of fine varieties in the main production areas of my country is low. Most of the production gardens are still old varieties decades ago. There are problems such as hard kernels, small grains, low fruiting rate, poor appearance, and low sugar content. Therefore, scientific and technological workers have been conducting research on the propagation of pomegranate seeds. Not only the reproduction speed is slow, but also the survival rate of some good varieties is very low, and the seedlings are very few, which is difficult to meet the requirements of mass and rapid breeding; the other is the use of plant tissue culture technology, but due to the large one-time investment and Due to the dis...

[0002] At present, my country's pomegranate production has been developing slowly for many years. The main reason is that the popularity rate of fine varieties in the main production areas of my country is low. Most of the production gardens are still old varieties decades ago. There are problems such as hard kernels, small grains, low fruiting rate, poor appearance, and low sugar content. Therefore, scientific and technological workers have been conducting research on the propagation of pomegranate seeds. Not only the reproduction speed is slow, but also the survival rate of some good varieties is very low, and the seedlings are very few, which is difficult to meet the requirements of mass and rapid breeding; the other is the use of plant tissue culture technology, but due to the large one-time investment and Due to the disadvantages of high cost, complicated technical steps, weak test-tube seedlings, low survival rate, and difficult promotion, the productivity of this technology in practical production is still quite limited. So far, this technology has mainly stayed in the laboratory

[0003] In recent years, plant propagation has mostly adopted the more advanced full-light spraying twig cutting seedling raising technology. This technology refers to using semi-lignified twigs as cuttings under full sun conditions, and adopting automatic intermittent spraying equipment to carry out large-scale cultivation. Seedling cultivation, it has the advantages of fast rooting of cuttings, short seedling cultivation period and abundant sources of cuttings, but there are many disadvantages in full-light spray cuttings: first, the cuttings are done in the open air, and it is difficult to quantitatively and accurately control the humidity and temperature. This affects the rooting and growth of cuttings; the second is that the full-light spray cuttings are generally used as a seedbed on the ground for cuttings. The cutting substrate is soil, which has poor air permeability and heavy soil. rooting rate; and the survival rate of cutting seedlings transplanted after cutting is low; third, full-light cutting is a method of cutting in summer, which is limited by seasons, climate and other conditions, and the reproduction coefficient is relatively low. Generally, it can only reproduce 1 or 2 times a year. Fourth, under the strong sunshine in summer and the resulting high temperature, the cutting shoots are easily damaged by sunburn, lose water and wither, and hinder the rooting of cuttings.
