A kind of seedling substrate production device, process and the seedling substrate block produced by the same

Abstract

The invention provides a seedling-raising matrix production device, a process and a seedling-raising matrix block produced, belonging to the field of plant cultivation. The process includes the following steps: preparation of raw materials; loading; Under the action of the microwave field, the wetted matrix material is rapidly heated, and the hot-melt solidified fibers in it can be melted in a controllable manner. The matrix raw materials are bonded to each other; after cooling and forming, after the compact is moved to a certain level, the water seepage system, the microwave generating device and the pressure mechanism are closed, cooled and demolded to form a solidified matrix block. The cured matrix with improved moisture distribution produced by the present invention has relatively stable appearance structure and microstructure and better moisture characteristics.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a seedling-raising matrix production device, a process and a seedling-raising matrix block produced therefrom. Background technique [0002] Substrate cultivation is an important soilless cultivation method and the most important modern commercial cultivation method. Typically, the first stage of commercial substrate cultivation is the nursery phase, during which it is common practice to place seeds in a nursery substrate filled in hole nursery trays. In more specialized commercial nurseries, Seedling blocks made of rock wool or other synthetic materials are often used. Once a plant is rooted and leaves grown in the seedling medium, it can then be transplanted to the next growth stage, usually to another seedling medium of a larger volume in the same facility or another facility. [0003] The goal of the breeder is to ensure that the seeds grow quickly but...

Problems solved by technology

A difficulty that arises from this is ensuring that all climatic conditions supplied to the seeds during the nursery phase, such as water, oxygen levels, are suitable to obtain seedlings with optimum performance

For example, seeds need to have access to enough water for the radicle to grow and take root quickly and efficiently; however, if the water content of the seedling substrate is too high, the oxygen content tends to become lower, which results in roots that are too long and not strong enough

[0004] This puts forward high requirements on the substrate moisture, but due to the limited capacity of the seedling substrate block, the water in it is easy to be excessive, and it is also easy to be evaporated so that the moisture content is too low

For example, under ideal conditions, the water content in the seedling substrate is about 75%, but in reality, a little watering will cause the water content to exceed 100%

Too high water content leads to low germination rate and low quality of plants, which often makes nursery growers tend to water less seedling substrates, often resulting in poor seedling growth

Especially for those crop types that develop slowly during the germination and nursery phases, such as sweet peppers, traditional substrate blocks can cause certain problems, for example, the risk of fungal growth due to poor moisture management during cold and wet winter conditions Very high, and the risk of poor rooting is also great; due to the limited capacity of existing matrix block products, the moisture in the matrix block is prone to drastic changes, too high or too low
