Nutrient matrix for soilless seedling cultivation of rice

Abstract

The invention discloses a rice soilless seedling raising nutrition matrix. The formula of the matrix comprises an original matrix with turf and vermiculite mixed according to the volume ratio of 3 : 1. The rice soilless seedling raising nutrition matrix is characterized in that 3.5 kg-4.5 kg of potassium chloride compound fertilizer, 10 g-15 g of fulvic acid, 8 kg-10 kg of zeolite powder adsorbents, 8 g-10 g of chitin and 10 g of silicon fertilizer are added into each cubic meter of original matrix and are evenly mixed. The rice soilless seedling raising nutrition matrix can meet the requirement of whole rice seedling stage growing and developing, extra nutrient solutions do not need to be poured, and the matrix has multiple effects of nutrition, drought resisting and disease resisting and is suitable for promotion and application.

Description

technical field [0001] The invention relates to the technical improvement of rice seedling raising substrates, in particular to the preparation of nutrient substrates for rice seedling raising without soil, and belongs to the field of industrialized seedling raising in agriculture. Background technique [0002] Soilless seedling cultivation is the core technology of industrial seedling cultivation. Most of the current soilless seedling cultivation adopts solid substrates. It is recognized at home and abroad that the choice of solid substrates is the compound substrate of "peat: vermiculite 2-3:1 (volume ratio)". No substance is added to this mixed matrix, and its nutritional method has always been to water the nutrient solution. The preparation of the nutrient solution is cumbersome and costly, and certain preparation containers and watering machines are required, especially under the conditions of industrialized seedling cultivation.

[0002] Soilless seedling cultivation is the core technology of industrial seedling cultivation. Most of the current soilless seedling cultivation adopts solid substrates. It is recognized at home and abroad that the choice of solid substrates is the compound substrate of "peat: vermiculite 2-3:1 (volume ratio)". No substance is added to this mixed matrix, and its nutritional method has always been to water the nutrient solution. The preparation of the nutrient solution is cumbersome and costly, and certain preparation containers and watering machines are required, especially under the conditions of industrialized seedling cultivation. A set of special nutrition is also required. Liquid device, in addition, there is a certain degree of insecurity when using it. If it is poured too much, it will easily cause concentration obstacles, and if it is poured too little, it will not be able to 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 solid soilless seedling nutrient substrate for rice
