Problems solved by technology

In order to reduce damage to the environment and excessive consumption of natural resources, and make tobacco production sustainable, in recent years, scientific and technological workers from all over the world have made a lot of explorations and attempts, such as using bagasse, dregs and carbonized straw as substitutes. Natural peat soil and expanded perlite, but due to the high comprehensive production cost of these materials and the unsatisfactory actual use effect, it is difficult to popularize and apply them in production

Embodiment 1

[0022] Get product of the present invention according to existing tobacco floating seedling raising tray specification, according to the mass ratio 4: 5.8: 0.2 mixed finished product of red loam and carbonized rice husk and clothes slow-controlled release special-purpose compound fertilizer, every 30kg packs 15 seedling raising trays, Tobacco seedling cultivation experiments were carried out in the seedling greenhouse. After observation and analysis, compared with the grass carbon substrate, the seedling emergence rate was equivalent, the strong seedling rate reached 95.3%, and the strong seedling rate was 3.2% higher than the grass carbon substrate.

Embodiment 2

[0024] Get product of the present invention according to existing tobacco seedling raising dish specification, according to the mass ratio 5: 4.9: 0.1 mixed finished product of red loam and carbonized rice husk and clothing slow-controlled release special-purpose compound fertilizer, every 30kg dresses seedling raising dish 14, in Tobacco seedling experiment was carried out in the nursery greenhouse. After observation and analysis, compared with grass carbon substrate, its seedling emergence rate was equivalent, the strong seedling rate reached 93.3%, and the strong seedling rate was 2.5% higher than grass carbon substrate.

Embodiment 3

[0026] Get product of the present invention according to existing tobacco upland seedling raising mode, according to the mass ratio 5.5: 4.3: 0.2 mixed finished product of red loam soil and carbonized rice husk and clothing slow-release controlled-release special compound fertilizer, evenly spread in the greenhouse about 3- It is 5cm thick, and the tobacco seedling raising experiment was carried out in the seedling greenhouse. After observation and analysis, compared with the grass carbon substrate, its seedling emergence rate is 5.68% higher, and the strong seedling rate reaches 94.3%.

Abstract

The invention discloses a novel tobacco seedling raising matrix and a preparation method thereof. The novel tobacco seedling raising matrix comprises the components in the proportion of 4:5.8:0.2-6:3.9:0.1: red soil, carbonized rice hull and a coated slow release special compound fertilizer. The matrix contains rich organic matters, potassium-phosphorus-potassium and mineral nutritional elements, has proper physical performance and potential of hydrogen, and has the advantages of wide material source, simple and labor-saving machining equipment, low cost, high puffing permeability of the matrix, high water retaining and nutrient preserving capacity and convenience in decentralized operation of farmers.

Description

technical field [0001] The invention belongs to the technical field of crop seedling raising, and relates to a crop seedling raising substrate and a preparation method thereof, in particular to a novel tobacco seedling raising substrate and a preparation method thereof. Background technique [0002] At present, in the production of tobacco seedlings, the substrate sources used mainly rely on non-renewable natural resources such as natural peat soil and expanded perlite, and these resources are very limited and are facing depletion. In order to reduce damage to the environment and excessive consumption of natural resources, and make tobacco production sustainable, in recent years, scientific and technological workers from all over the world have made a lot of explorations and attempts, such as using bagasse, dregs and carbonized straw as substitutes. Natural peat soil and expanded perlite, but due to the high comprehensive production cost of these materials, and the unsatisfa...
