Coffee cutting seedling culture method

Abstract

The invention relates to the field of agricultural technology, and discloses a coffee cutting seedling culture method. The method comprises the following steps of: selecting a robusta coffee straight branch and cutting to obtain a cutting shoot; soaking the cutting shoot in 200mg / L IBA or 200-300mg / L NAA for 0.5-1.5h; inserting the treated cutting shoot into a cutting matrix for primary seedling culture; and then transferring to nutrient soil for later-stage seedling culture to obtain a coffee cutting seedling, wherein the nutrient soil is a matrix obtained by adding calcium superphosphate and surface soil into the excrement of animals for thorough decomposition. The traditional treatment method of a plant growth regulator is changed according to the robusta coffee growth characteristics, and reasonable nutrient soil is added to perform later-stage seedling culture; and the invention provides a systematic and comprehensive robusta coffee cutting seedling culture method which overcomes the shortcomings that the existing method is non-comprehensive and the rooting effect is bad, and is of far-reaching significance for increasing the output of the robusta coffee.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for growing seedlings by cuttings of coffee. Background technique [0002] Coffee (tree) is a perennial evergreen shrub or small tree of the Rubiaceae family. It is a horticultural perennial economic crop. The fruit is one of the three famous beverages with aroma. There are small, medium and large varieties of coffee. Among them, the medium-grained coffee is cross-pollinated, and the yield of the seed tree varies greatly. Some offspring of the same high-yielding mother plant have high yields, and some have low yields, and the differences are large. Long-term use of seedlings, due to the low yield of plants that occupy a considerable proportion in the coffee garden, causes the yield per unit area of ​​coffee to be low. Therefore, the method of seed breeding needs to be reformed urgently. [0003] Cuttings, also known as cuttings, are a common propagation method fo...

AI Technical Summary

Problems solved by technology

[0004] Existing reports on coffee cutting seedling cultivation are few, and only a few documents have reported the experiments of various factors affecting coffee cutting seedling cultivation, such as "Brief Report on Cutting Experiment of Medium-grained Coffee" (Zhang Jixiang et al., China Tropical Agriculture, 2012, 4, total No. 47), which conducted single-factor experiments to verify the suitable cuttings from various aspects such as cutting bed substrate, plant growth regulator, maturity degree of straight shoots, rooting time of cuttings, length of cuttings, whether the cuttings were topped or not. Optimum conditions for each factor

However, this document is only a single-factor exploratory experiment, and does not give a complete method for cutting seedlings, nor does it comprehensively consider the mutual influence of various indicators

And the existing literature also lacks the content of transplanting and growing seedlings after cutting bed cultivation and cuttings are handled when plant growth regulators are processed. Simply go cutting and growing seedlings according to the method announced in this document, and its rooting effect is not very satisfactory, such as rooting rate, Root length, root coefficient, root diameter, and the rooting effect and plant growth status of coffee seedlings in the later stage (plant height, stem diameter, number of leaves, etc.) are important indicators to determine the quality of coffee seedlings. Are the coffee seedlings that come out easy to survive?
