Industrialized rice seedling matrix and method of raising seedlings

Abstract

The invention provides an industrialized rice seedling matrix and a method of raising seedlings. The industrialized rice seedling matrix is prepared from, by weight, 20%-30% of straw leavening materials, 15%-25% of peat, 10%-20% of organic fertilizer, 5%-10 % of clay, 2%-5% of adhesive, 1%-4% of water-retaining agents, 2%-5% of vermiculite, 0.5%-0.8% of seedling strengthening agents, 0.5%-4.0% of nitrogenous fertilizer, 0.2%-3.0% of phosphatic fertilizer, and 0.6%-2.0% of potash fertilizer. By adding ingredients including organic fertilizer, water-retaining agents, adhesive and the like, the seedlings bred by the industrialized rice seedling matrix have the advantages of growing evenly, strongly and orderly, providing high efficiency, obviously reducing costs of breeding seedlings at the same time, and obviously decreasing load of rice transplanters and labor intensity of farm work due to seedling trays of finished products.

Description

Technical field: [0001] The invention belongs to the technical field of rice seedling raising substrates, and in particular relates to an industrialized rice seedling raising substrate and a seedling raising method thereof. Background technique: [0002] Traditional rice seedling raising is often done directly in the paddy field. With the development of science and technology, more and more rice seedling raising machines are used for rice seedling raising. However, the rice seedling raising machine still uses the traditional seedling raising process, that is, directly laying rice seeds Seedlings are raised in a seedling tray filled with paddy field soil. Due to the compaction and solidification of the soil, it is difficult to separate the mature seedlings, which is not conducive to mechanical transplanting. In addition, topdressing is required during the growth of the rice seedlings, resulting in high production costs. In view of the above-mentioned defects, it is necessary ...
