Problems solved by technology

[0002] The current soilless seedling cultivation of vegetables uses solid substrates. It is generally accepted at home and abroad that the choice of solid substrates is the compound substrate of "peat: vermiculite 2:1 (volume ratio)". The method has always been to irrigate the nutrient solution. The configuration of the nutrient solution is cumbersome and costly. It also needs a certain configuration of containers and irrigation machinery. Especially under the conditions of industrial seedling cultivation, a set of special nutrient solution devices are required. Safety, if you pour too much, it will easily produce concentration barriers, if you pour too little, it will not meet the needs of seedling growth and development
If the nutrients are simply mixed into the original substrate, the buffering property of the substrate is not as good as that of the soil, resulting in a concentration barrier at the time of emergence, so it is very difficult to develop a vegetable solid soilless seedling nutrient masterbatch

Embodiment 1

[0014] The original matrix of peat and vermiculite mixed in a volume ratio of 2:1, including 2.2 kilograms of potassium sulfate compound fertilizer, 14 grams of fulvic acid, and 10 kilograms of zeolite powder adsorbent in each cubic meter of the original matrix, can be evenly mixed.

Embodiment 2

[0016] The original matrix of peat and vermiculite mixed in a volume ratio of 2:1, including 1.8 kg of potassium sulfate compound fertilizer, 12 grams of fulvic acid, 9 kg of zeolite powder adsorbent, and 5-8 chitin per cubic meter of the original matrix. grams, 50-100 grams of water-retaining agent, just mix evenly.

[0017] Put the solid nutrient matrix of the present invention directly into the hole tray, pour enough water and sow directly, the seedlings emerge quickly and neatly, and the cotyledons are hypertrophic, the growth and development of the seedlings are fast and robust, and the management only needs to be watered as needed, which greatly simplifies Seedling raising procedures and improved seedling quality. In the end, it can achieve better than conventional nutrient solution cultivation:

[0018] (1) The seedling period is shortened by about 1 / 3;

[0019] (2) The index of strong seedlings is increased by about 30%;

[0020] (3) The output is increased by about...

Abstract

The invention discloses vegetable soil free culture of seedling nutrition master agent, and relates to the technical improvement on vegetable culture of seedling, in particular to a preparation for comprehensive nutrition master agent used for preparing the substrate of vegetable soil free culture of seedling, and belongs to the field of agriculturally industrial culture of seeding. The invention provides the vegetable soil free culture of the seedling nutrition master agent without concentration obstacle and being capable of continuously fertilizer feeding and simplifying the culture of seeding procedure. The invention comprises primary substrate which combines grass carbon and vermiculite with volume proportion of 2:1. The invention is characterized in that the primary substrate of each cubic meter comprises 1.5 to 2. 5 kg of lemery type composite fertilizer, 10 to 15 g of fulvic acid, and 8 to 10 kg of zeolete sorbent, which are mixed evenly.
