Problems solved by technology

When the light is insufficient, the growth of plants is inhibited; and if the light is too much, it will cause burns to the leaves, which is also not conducive to crop growth (Corot et al 2017, Zhang Minghong 2018)

Embodiment Construction

[0021] The principles and features of the present invention are described below, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0022] A method for hydroponic cultivation of peach seedlings, specifically comprising the following steps:

[0023] 1. Select the seeds of the wild peach in the same year as the test material. Wash off the surface impurities of peach seeds with clean water, soak for 2-3 days to make the seeds fully absorb water; mix the seeds and wet sand at a ratio of 1:5, stack them in a plastic box, keep a certain humidity, and carry out low-temperature stratification in a 4°C refrigerator. The humidity of the sand is advisable to form a ball by hand, and loosen it when you let go; observe whether the seeds are white every 5 days, and after the seeds are white, they are sown in clean vermiculite for 1 week, and a single plant with the same growth is selected and moved to a ...

Abstract

The invention relates to a hydroponic method for peach seedlings. The hydroponic method comprises the following steps that the peach seedlings are cultured by the hydroponic method, the oxygen introduction time is set to be 30min/h in the culture period, a 1/4-fold Hoagland nutrient solution is adopted as the hydroponic nutrient solution, 2500lx illumination intensity and constant temperature of 25 +/-1 DEG C are adopted, and the illumination time is 16h/d. According to the hydroponic method for the peach seedlings, a hydroponic system is established in peaches for the first time, the growth environment of the peach seedlings can be accurately regulated and controlled, and the influence of the external environment on growth of the peach seedlings is explored by clearly and visually observing the root system form and the plant phenotype. The hydroponic method for the peach seedlings is not limited by the field environment, annual supply can be achieved, the research period is shortened,a convenient technical means is provided for scientific research, and the hydroponic method for the peach seedlings has important significance in research of plants (especially root systems) with thepeach seedlings as research objects and the external environment.

Description

technical field [0001] The invention relates to the field of peach cultivation methods, in particular to a hydroponic method for peach seedlings. Background technique [0002] For a long time, peach trees have been planted and scientifically studied by soil cultivation. Due to being in an open-air environment, there are many uncontrollable factors, and the plants are easily affected by the soil environment, resulting in the breeding of diseases and insect pests and uneven nutrient absorption, etc.; and soil cultivation is time-consuming and labor-intensive, and the input cost is high (Rutto and Mizutani 2006, Bent et al 2009). In addition, as a perennial plant, the peach tree has a wide distribution of root systems. Excavating from the soil can easily destroy the integrity of the root system, and it is difficult to clean, which makes it very difficult to observe the root system (Dunying 2011). If the traditional soil cultivation method is used to study the influence of the...
