Paddy rice seedling raising substrate

Abstract

The invention discloses a paddy rice seedling raising substrate. The paddy rice seedling raising substrate comprises the following raw materials by weight: 15 to 25 parts of sieved alga peat soil, 5 to 12 parts of rice chaff charcoal, 5 to 12 parts of humus soil from remote mountains, 8 to 16 parts of selenium-rich mineral matters, 6 to 16 parts of decomposed straw powder and 5 to 12 parts of herb residues, wherein the herb residues are prepared by subjecting mixture of pine needle, Radix Stemonae, Eupatorium adenophorum, Dendrobium, licorice root and Radix Codonopsis to high-temperature aerobic fermentation. The substrate is proper in composition, excellent in physical and chemical properties, good in air permeability and strong in water retention and fertilizer conservation capabilities, can meet demands of seedlings for oxygen, nutrients and moisture, enables seedlings to be strong, has improved adaptability and reduces seedling raising cost.

Description

technical field [0001] The invention relates to vegetable seedling raising, in particular to a rice seedling raising substrate. Background technique [0002] Soilless cultivation refers to the method of cultivating crops and raising seedlings with substrates without using natural soil. It is mainly used in the production of fruits, vegetables or flower seedlings. It is an advanced high-yield and high-quality cultivation technology that saves water, fertilizer and labor. Substrate cultivation is a method with the largest promotion area in soilless cultivation. It fixes the root system of the crop in an organic or inorganic substrate, and supplies the crop nutrient solution through drip irrigation or trickle irrigation. At present, most countries in the world use gravel, sand, mud (grass) charcoal, vermiculite, chaff charcoal, rock wool, sawdust, etc. as fixed substrates. The ideal cultivation substrate recognized in the world is peat and rock wool. But peat and rock wool a...

AI Technical Summary

Problems solved by technology

At present, the ratio of rice seedling substrates in the market is very chaotic, resulting in poor physical and chemical properties of the substrate, poor permeability, poor water and fertilizer retention capacity, etc., resulting in poor root development of seedlings, thin plants, and poor resistance, which seriously affects the quality of seedlings. Colleagues still have problems such as inconvenient long-distance transportation
