Rice machine transplanting seedling cultivation substrate, preparation method and application

Abstract

The invention discloses a rice machine transplanting seedling cultivation substrate, which comprises the following components: in mass percentage, 0.014 to 0.9% of bactericide, 42% to 90% of pig manure ferment, 15% to 45% of agricultural by-product residue, 0.5 to 5% of a dispersant and the rest being a filler. The invention also discloses a preparation method for the rice machine transplanting seedling cultivation substrate. The method comprises the following steps: (1) fenaminosulf, fludioxonil and azoxystrobin are taken, the dispersant and the filler are added for mixing, and after stirringand crushing, bactericide powder is obtained; (2) the pig manure and superphosphate are mixed for piling fermentation and transferred to a fermentation tank for fermentation and maturity, and the pigmanure ferment is obtained; (3) traditional Chinese medicine residue, alcohol fermentation biogas residue and edible fungus residue are mixed for piling maturity, and after drying and crushing, the agricultural by-product residue is obtained; and (4) the bactericide powder, the pig manure ferment, the agricultural by-product residue and the filler are mixed to obtain the rice machine transplanting seedling cultivation substrate. Through adding the bactericide in the pig manure ferment, diseases can be prevented while the rice machine transplanting seedling cultivation substrate provides nutrition, and in match with the agricultural by-product residue, the above effects are further enhanced.

Description

technical field [0001] The invention relates to the technical field of rice growth substrates, in particular to a rice machine-transplanted seedling-raising substrate, a preparation method and an application. Background technique [0002] The mechanization of rice planting is the main development direction of modern rice farming technology in my country. It is of great significance to stabilize grain production under the conditions of rural labor force transfer and aging, promote large-scale rice production, and improve labor production efficiency. [0003] Rice needs sufficient nutrient supply during the growth period. At present, most of the machine-transplanted seedling-raising substrates are seedling-raising substrates that use zeolite as a carrier and add fertilizers, or use crop straws to add decomposed organic fertilizers, crushed soil, decomposing agents and other auxiliary materials to process seedling-raising substrates. Wait. In addition, there are diseases such ...
