Problems solved by technology

For example, some light materials are used to improve the water retention after a series of treatments, but the water permeability is still poor; if the seedlings are raised with plant ash, the seedlings produced are weak
Using minerals such as vermiculite and perlite as the substrate for rice seedlings generally has problems such as poor packing, easy breakage when taking seedlings, and easy falling apart when putting them on the rice transplanter.

Abstract

The invention discloses a rice soilless seedling raising nutritional medium and a preparation method thereof. The rice soilless seedling raising nutritional medium is prepared from the following raw materials: carbonized rice husks, cassava residues, sucrose slag, livestock and poultry manure, a straw powder, tea residues, waste tobacco leaves, microbial fungi, a plant growth promoter and water. The rice soilless seedling raising nutritional medium provided by the invention takes agricultural wastes as raw materials to avoid damage to topsoil; the nutrient components are abundant and the content of organic matters is high, so that the rice can obtain full nutrition supply during the whole seedling. The rice seedlings cultivated by the rice soilless seedling raising nutritional medium havethe advantages of developed root systems, high packing force, robust seedling stems, high survival rate after transplanting, high adaptability, few pests and diseases and robust growth.

Description

technical field [0001] The invention relates to the field of rice planting, in particular to a nutrient matrix for soilless seedling cultivation of rice and a preparation method thereof. Background technique [0002] Rice mechanized transplanting is the main development direction of high-efficiency rice cultivation technology, and it is also an important means to improve rice production efficiency. However, due to the high requirements for rice seedlings in rice mechanized transplanting, it is difficult to cultivate high-quality rice seedlings suitable for machine transplanting, which has become an important factor affecting rice production. One of the main factors of mechanized transplanting. [0003] The rice seedling substrates used today mainly include the following two types: one is a substrate made of a mixture of local soil, fertilizers, and growth regulators, and the other is a substrate made of other resources through different treatments such as composting and ferm...
