Example Embodiment

[0020] Example 1. Preparation of volcanic gravel seedling substrate

[0021] Collected volcanic gravel and volcanic ash soil (0-25cm arable layer soil) widely distributed in the wild in Tengchong County, Yunnan Province, dried, air-dried, beaten, and passed through a 40-50 mesh sieve, with the largest particle size <6mm; at the same time, the corn stalks and rice husks are air-dried, air-dried, and crushed, and then passed through a 40-50 mesh sieve, the largest particle size <6mm.

[0022] The bulk density of volcanic ash soil is 0.87g / cm 3 , The pH value is 6.03, the soil organic matter content is 3.80%, the alkali-hydrolyzable nitrogen content is 127mg / kg, the available phosphorus (Olsen-P) content is 13.4mg / kg, the available potassium (NH 4 OAc-K) content is 247mg / kg.

[0023] Using a volume meter, mix the volcanic gravel, volcanic ash soil, corn stalks, and rice husks in a volume ratio of 3:3:2:2, 4:2:2:2, and then pile up and mature for 28 days after adding water , Turn the pil...

Example Embodiment

[0026] Example 2. Verification of the effect of flue-cured tobacco seedlings on the volcanic gravel seedling substrate

[0027] In order to verify the actual effect of the volcanic gravel seedling substrate, the inventors used the conventional peat substrate material (the proportion of peat is 53%) as a control, and the tested flue-cured tobacco variety was Yunyan 87 coated seed, and carried out a comparative test of tobacco floating seedlings. The floating seedling tray uses a 200-hole polystyrene foam grid tray with a size of 34cm×68cm×6cm. The single bowl is in the shape of an inverted stepped platform, the diameter of the small hole at the bottom is 0.6cm, and the volume of the single cavity is about 27cm 3 . Three repetitions are set for each treatment, and 3 trays are repeated each time. The same duplicates are placed in the same nursery pond.

Abstract

The invention discloses a volcanic gravel type flue-cured tobacco seedling substrate and a preparation method thereof. The preparation method of the volcanic gravel type flue-cured tobacco seedling substrate comprises the following steps: mixing the following materials in parts by weight: 2.5-4 parts of volcanic gravels, 2-3 parts of volcanic ash soil, 2-3 parts of corn stalks and 2-3 parts of rice husk, composting and thoroughly decomposing. The volcanic gravel type flue-cured tobacco seedling substrate disclosed by the invention is used for replacing the existing grass carbon-based seedling substrate, and tobacco seedlings cultured by using the volcanic gravel type flue-cured tobacco seedling substrate are similar to or partially superior to the tobacco seedlings cultured by the grass carbon-based seedling substrate on the aspects of the emergence rate, the growth and development of the tobacco seedlings and the like. Since the volcanic gravels and volcanic ash soil used for preparing the volcanic gravel type flue-cured tobacco seedling substrate can be directly obtained from the natural environment and moreover the straws, the rice husk and the like are waste resources, compared with substrate materials prepared from grass carbon and the like, the volcanic gravel type flue-cured tobacco seedling substrate has the advantages of abundant raw material storage capacity, low cost, no generation of wastes and the like and has relatively high social, economic and ecological benefits.

Description

technical field [0001] The invention belongs to the technical field of organic seedling-raising substrates, and in particular relates to a flue-cured tobacco seedling-raising substrate prepared by using volcanic gravel. At the same time, the invention also relates to a preparation method of the flue-cured tobacco seedling raising substrate. Background technique [0002] Flue-cured tobacco is one of the important economic crops in our country. At present, the planting areas are mainly distributed in old, young, frontier and poor areas, which is of great significance to improving the economic level of local farmers. The prerequisite for ensuring the production of flue-cured tobacco is the cultivation of tobacco seedlings. Cultivating timely seedlings, sufficient quantity, neat and strong tobacco seedlings is the basis for obtaining high-quality tobacco leaf production. The ideal high-quality tobacco seedlings should be disease-free, well-developed root system, strong stress ...
