Problems solved by technology

Agricultural wastes such as rice husks and straws are widely used as biomass resources. The seedlings bred on such substrates are strong and neat, with tightly packed roots, and the seedlings are not easy to break, but the disadvantages are poor water permeability and low water retention. low rate
Mineral resources are mostly used in perlite, vermiculite, etc. This type of matrix has strong water retention and water permeability, large root volume, and strong rooting force, but the disadvantage is that the packing is poor, and it is easy to break when taking seedlings and rolling seedlings. fall apart

Abstract

The invention discloses a matrix for rice hole tray seedling raising. The matrix comprises the following components in parts by weight: 100 parts of straw powder, 20-40 parts of plant ash, 40-60 parts of vermiculite and 5-10 parts of polyacrylamide particle. Compared with the existing rice seedling raising matrix, the rice seedling raising matrix disclosed by the invention has the advantages of easy water seepage and favorable water retention property, and the raised seedlings are strong and regular and have the advantages of high root weight, compact root and low tendency to rupturing and falling apart of the seedling piece.

Description

technical field [0001] The invention relates to a substrate for growing seedlings in plug trays of rice. Background technique [0002] At present, the industrialization of rice seedling cultivation is rapidly popularizing in various rice areas across the country, and soil for seedling cultivation has become the main problem in current agricultural production. Because rice seedlings have high requirements on soil quality and a large amount of soil, the soilless or matrix seedlings of rice came into being. [0003] The existing substrates for rice seedlings can be roughly divided into biomass resources and mineral resources. Agricultural wastes such as rice husks and straws are widely used as biomass resources. The seedlings bred on such substrates are strong and neat, with tightly packed roots, and the seedlings are not easy to break, but the disadvantages are poor water permeability and low water retention. low rate. Mineral resources are mostly used in perlite, vermiculi...
