Problems solved by technology

Due to the different growth characteristics of different plants, the substrates used in trees and flowers cannot be completely transferred to corn cultivation. Therefore, to study a cultivation substrate suitable for corn potted plants is a problem that needs to be solved urgently in the research of corn potted plants.

[0040] 4. Soil filling: After the pots and pots required for the test are arranged in order according to the method of 2 above, they can be filled with soil and buried. When filling the soil, pay attention to the surrounding pots and pots at the same time, so as to keep the pots upright and the pots and pots in a suitable position. distance;

[0041] 5. Corn potted culture medium: the organic matter content of the corn potted culture medium is 76.9%, the content of humic acid is 20%, the total content of nitrogen, phosphorus and potassium is 3%, the ratio is 3:1:2, and the trace element zinc The content is 0.1%, the matrix is ​​put into the pot, the filling amount is 4 / 5 of the pot volume, and the packing density is 1 g / cm 3 ;

[0042] 6. Soil loading: According to the purpose and task of the test, select the soil in the plow layer, remove the stones and plant rhizome debris from the retrieved soil, pass it through a sieve with an aperture of 2-3 mm after a little dry, and s...

Abstract

The invention relates to the technical field of agricultural pot culture, in particular to a medium for culturing potted corn. The medium comprises the following components by weight percent: 10-76.9% of organic matters, 20-57% of humic acid, 0-22.9% of nitrogen, phosphorus and potassium and 0.1-10.1% of trace elements, wherein the ratio of nitrogen to phosphorus to potassium is 3:1:2. A method for culturing potted corn comprises the steps of selecting pots, digging a burying ditch, burying the pots, filling soil, filling the medium, filling soil, applying fertilizers, injecting water, sowing seeds and covering vermiculite. The medium and the method have the following beneficial effects: the medium is beneficial to promoting corn root development and realizing deep rooting and root development of corn; tests show the drainage volumes of the potted corn roots with the medium added and vermiculite covered can reach 156-285 milliliters, an increase of 73-216% compared with the conventional soil culture methods; and the root length reaches 1.4 meters, an increase of about 1 meter compared with the conventional soil culture methods.

Description

technical field [0001] The invention relates to the technical field of agronomic potted cultivation, in particular to a corn potted cultivation substrate, and also relates to a corn potted cultivation method. Background technique [0002] Pot test is the most common type of cultivation test. It uses special containers to conduct research on crop nutrition and fertilization, crop growth and development, or crop physiology under conditions such as artificial control of water, fertilizer, light, and temperature. . [0003] As early as 1640, Helmont conducted a willow pot experiment, which is considered to be the beginning of the study of plant physiology, and opened the study of photosynthesis and plant nutrition. Since then, pot experiments have been widely used due to the small volume of pots, the small number of cultivated plants, and the easy control of soil, fertilizer, water and other conditions, which is conducive to accurate single-factor research. [0004] The pot ...
