Embodiment Construction

[0023] The special substrate for tobacco soilless seedlings includes: 20-30% bio-organic fertilizer, 65-80% organic material, 2-5% chemical fertilizer, 1-2% sulfuric acid, 0.5-1.5% fungicide and 5-20mg / kg blending agent.

[0024] The bio-organic fertilizer is high-quality bio-organic fertilizer produced by inoculating Beijing Puyuan Company's "organic waste fermentation koji" at 55-65° C. for 5-7 days after high-temperature fermentation.

[0025] The chemical fertilizers include: urea, ammonium sulfate and zinc sulfate.

[0026] The organic materials are: rice husk, straw carbide and rice husk ash.

[0027] Described bactericide: metalaxyl, oxaxyl.

[0028] Described regulator: rooting agent, naacetic acid, brassinolide.

[0029] The beneficial microorganisms are bacteria, fungi and actinomycetes forming a composite flora.

[0030] Described preparation method is as follows:

[0031] 1. Complete the production of organic fertilizer: first dry the manure of livestock and po...

Abstract

The invention discloses a matrix special for tobacco soilless seedling and a preparation method thereof. The matrix consists of the following raw materials: 20-30% of microbial organic fertilizers, organic matrix materials including carbonized rice hulls and rice hull ash, 65-80% of plant straws, 2-5% of fertilizers, 1-2% of acid regulating agents, 0.5-1.5% of bacteriacide and 5-20mg/kg of regulating agents. The matrix special for the tobacco soilless seedling contains 6% of organic matter, 1.8% of humic acid and larger than 5.4% of N, P and K, and is rich in various trace elements such as Ca, S, Si, Mg, Zn, Fe and B. When the matrix is used for raising seedlings, tobacco seedlings have lots of root hair and large root capacity; stem leaves on the ground are thick and stout and do not grow excessively; the seedlings do not suffer from seedling diseases, do not need recovery after transplanted, directly grow root to survive, and has high survival rate; and tobacco leaves have high grade and large yield. Therefore, the purposes of improving quality, increasing yield and increasing income can be achieved.

Description

technical field [0001] The invention relates to the technical field of tobacco cultivation, in particular to a tobacco soilless seedling cultivation substrate and a preparation method thereof. Background technique [0002] Tobacco production has a long history in our country. With the development of tobacco production technology and the continuous improvement of the quality requirements of tobacco leaves, the fertile soil of dry fields in the past is no longer suitable for the requirements of tobacco production. Now the soil quality in dry fields is far worse than before. The organic matter content is less than 3%, the aggregate structure is less, the texture is heavy, cold and hardened, salinization and harmful pesticide residues are serious, and the time for flue-cured tobacco seedlings is mid-March, and the outside has not yet thawed , It is necessary to dig back the frozen soil, thaw it indoors, and then fry it dry in a pan. After the medicine is sterilized, mix it with ...
