Machine-transplanted rice seedling raising substrate

Abstract

The invention discloses a machine-transplanted rice seedling raising substrate. The substrate is prepared from, by weight, 100 parts of plant ash, 30-50 parts of vermiculite and 4-6 parts of polyacrylamide particles. Compared with an existing rice seedling raising substrate, according to the machine-transplanted rice seedling raising substrate, water seepage is easy, the water-retaining property is good, raised seedlings are robust and regular, the root number is large, roots are twined compactly, and seedling pieces are not prone to break and fall apart.

Description

technical field [0001] The invention relates to a machine-transplanted rice seedling raising substrate. 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, vermiculit...

AI Technical Summary

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
