Problems solved by technology

Soilless hydroponics is more common in annual herbaceous crops, while perennial woody plants are relatively difficult to root, and the tree is too large to be fixed, which makes it difficult to use soilless hydroponics for cultivation. tree and other perennial woody fruit trees for any reported reason for soilless hydroponics

Embodiment Construction

[0024] The root system is the basis for the growth and development of fruit trees. If the root system is stable and strong, the tree body is stable and strong, and it and the tree body contain and restrict each other. The application of the invention can make pear trees take root quickly, and the root system is in good shape, which is beneficial to the research on the pear root system. The specific operation process is as follows:

[0025] (1) Screening of pear saplings

[0026] Select the 1-year life or 2-year life grafting seedling that uses on production for use, and rootstock is pear pear, and kind is common cultivar in production (the present invention takes Cuiguan pear as material). Seedling quality requirements: the thickness of 10 cm above the grafting interface is more than 0.8 cm, the height of seedlings is more than 100 cm, the main root system is about 20 cm long, and there are 5 lateral roots, and the growth is uniform. Before hydroponic cultivation of pear se...

Abstract

The invention discloses a pear tree water culturing method, belonging to the technical field of plant production. The method comprises the following four steps of: (1) selecting plantlets: selecting one-year or two-year pear graftings in production which are uniform in size and growth; (2) determining the formula of a water culturing nutrient solution consisting of 6mM of KNO3, 4mM of Ca(NO3)2, 2mM of NH4H2PO4, 1mM of MgSO4, 50muM of KCl, 10muM of H3BO3, 2muM of MnSO4, 2muM of ZnSO4, 0.5muM of CuSO4, 0.065muM (NH4)6Mo7O24 and 50muM of Fe-EDTA; (3) selecting a water culturing container; and (4) ventilating and changing the nutrient solution during the culture. The pear tree subjected to soilless culture of the method has the advantages of fast root system growing speed, good growth, high survival rate, healthy tree growth, and the like.

Description

1. Technical field [0001] The invention relates to a hydroponic method for pear trees, which uses a formula nutrient solution to carry out soilless cultivation of pear trees, so that pear trees can quickly take root in the nutrient solution and grow normally, and belongs to the fields of plant cultivation and ecology. 2. Background technology [0002] The root system of fruit trees has the functions of fixation, absorption, transportation and storage, and a well-developed root system is the basis for the normal growth and development of fruit trees. Fruit trees with well-developed and robust root systems also grow luxuriantly. Usually, the aboveground and underground parts of fruit trees are mutually contained, restricted and promoted. Therefore, it is necessary to study the growth and development of fruit tree roots and their absorption and utilization of water and nutrients. Characteristics have always been one of the key topics in the field of fruit tree cultivation and p...
