Multifunctional seedling culture matrix block prepared from plant straw and preparation method of seedling culture matrix block

Abstract

The invention relates to a multifunctional seedling culture matrix block prepared from plant straw and a preparation method of the seedling culture matrix block. The matrix block takes plant straw compost or turfy soil as a main material, miscellaneous Al2O3*nH2O powder, phosphorus diamine, efficient water-absorbent resin and plant growth-promoting and disease-resisting bacillus are added, the peripheral surface is coated with an elastic and degradable fiber net prepared from polylactic acid, a small hole I is formed in the center of the upper surface of the seedling culture matrix block and used for accommodating seeds, and multiple small holes II are formed around the small hole I and used for accommodating controlled-release fertilizer. The seedling culture matrix block can be applied to centralized and advance seedling culture before field transplantation in case of transplantation and can be implanted in a field through direct ditching, and the matrix block immediately meets requirements of water absorption and germination of the seeds after absorbing water. The seedling culture matrix block is widely applied to seedling culture for forest fruits, crops, flowers, plants and vegetables, can be transplanted in the field and a greenhouse in one step and can also be directly embedded in the field, the plastic culture hole cost is saved, a large quantity of crop straw is consumed, environmental pollution is reduced, the soil fertility is enhanced, and the matrix block has the very bright popularization prospect and the significant social and economic benefit.

Description

(1) Technical field [0001] The invention relates to a multifunctional plant straw-based seedling-raising substrate block and a preparation method thereof, belonging to the field of agricultural production materials. (2) Background technology [0002] In recent years, crop straws have been piled up for a long time to occupy land, and the environmental pollution caused by seasonal stubble burning has become increasingly serious. Traditional plastic seedling cultivation holes commonly used in agricultural production and scientific research are easily damaged and costly. They are also easy to damage the root system of seedlings when transplanting, and easily cause environmental pollution in farmland. Therefore, there is an urgent need to develop straw-based seedling-raising substrate nutrient blocks for removing crop straws, reducing environmental pollution, saving costs, and improving soil fertility. (3) Contents of the invention [0003] The purpose of the present invention...
