Seedling substrate dedicated for tobacco

Abstract

The invention discloses a seedling substrate dedicated for tobacco, which is composed of turf, perlite, vermiculite and a water soluble fertilizer, wherein the substrate is prepared from the following raw materials in weight: 75-80 kg of the turf, 2-5 kg of the perlite, 15-20 kg of the vermiculite, and 0.6-0.7 kg of the water soluble fertilizer of which the water content is not greater than 2%. According to the seedling substrate dedicated for the tobacco, the problems that tobacco seeds are smaller, and the contents of a rooting agent and a growth regulator in a vegetable seedling substrate are higher can be effectively solved, and the runt seedling phenomenon is prevented. The seedling substrate dedicated for the tobacco has the advantages of simplicity in preparation, reasonable prescription, stable performance, cost saving, strong water-retaining property, less weed, lighter phytotoxicity and good sprouting; according to the seedling substrate dedicated for the tobacco, not only can the substrate be disinfected, but also a disease-pest control and prevention effect can be achieved on the seedlings in the substrate; the nutrition requirements of the tobaccos in the seedling cultivation process can be completely met, and the proportion can be properly adjusted according to the characteristics of the cultivated tobacco variety; the seedling substrate dedicated for the tobacco is a special seedling substrate prescription which is suitable for northern tobaccos.

Description

technical field [0001] The invention relates to an agricultural seedling-raising matrix formula and its application field, in particular to a special matrix formula for tobacco seedling raising. Background technique [0002] At present, due to the influence of climatic factors, the tobacco-growing area in Northeast my country still implements the two-stage seedling raising method of early cropping. As time goes by, it becomes more and more difficult to collect the nutrient soil that has the effect of raising seedlings, and the intrinsic nutrient content of the nutrient soil is not good after collection. Balanced, it is easy to cause differences in the growth of tobacco seedlings in the mother bed. In the cultivation of flue-cured tobacco seedlings, there is no special seedling substrate at present, and most of them use vegetable seedling substrates. Due to the small tobacco seeds, and the high content of rooting agents and growth regulators in vegetable seedling substrates, i...
