Abstract

The invention discloses a soil-free plug seedling substrate. The seedling substrate comprises a substrate body and additives, wherein the substrate body is formed by mixing vermiculite and fully fermented and decomposed organic substrate materials in volume ratio of 1:1; and the added amounts of the additives are as follows: 3-5kg of bioorganic fertilizer in per cubic meter, 0.2-0.3kg of potassium sulfate in per cubic meter, 0.5-0.6kg of diammonium phosphate in per cubic meter, 30-40g of carbendazim in per cubic meter and 50-60g of 65% zineb powder in per cubic meter. According to the invention, soil-producing renewable resources are fully utilized, the seedling cost can be obviously reduced, the cultured seedlings grow vigorously, and the seedlings have no obvious growth delaying period after the planting. The substrate is particularly suitable for industrial plug seedling with low root disintegration rate, and is suitable for long-distance transportation. Therefore, the substrate has a brilliant application prospect.

Description

technical field [0001] The invention relates to the field of soilless cultivation, in particular to a soilless plug seedling raising substrate and a method thereof. Background technique [0002] In recent years, with the development of protected horticulture and the large-scale promotion and application of plug seedling technology, the demand for soilless seedling substrates has increased sharply. The seedling substrate can provide seedlings with a stable and coordinated growth medium of water, air, fertilizer and structure, and is an important part of soilless plug seedling cultivation. At present, most of the seedling substrates based on peat are the most widely used and the most ideal application effect. However, peat resources are limited, cannot be regenerated in a short period of time, and are limited by production areas, transportation is difficult, and sales prices are high, resulting in high seedling cost. Therefore, how to reduce the cost of raising seedlings and...
