specific Embodiment approach 1

[0013] Specific embodiment one: a kind of cold region rice seedling raising substrate of the present embodiment, the cold region rice seedling raising substrate is made of 30~60 parts of lignocellulosic materials, 10~30 parts of fly ash, 10~20 parts of peat, It is made of 10-20 parts of vermiculite and 10-20 parts of perlite; wherein the wood fiber material is edible fungus residue or straw powder.

[0014] The edible fungus residue in this embodiment is the compost after the edible fungi are cultivated.

[0015] The pH value of the rice seedling-raising matrix in the cold region of the present embodiment is between 4.5 and 6.0, and due to the addition of fly ash and vermiculite, it has the advantages of good thermal insulation and good water retention. The rice seedling-raising matrix in the cold region of the present invention is used The seedlings emerge quickly and neatly in the early stage. There is no need for disease prevention or weeding during the entire seedling cult...

specific Embodiment approach 2

[0016] Specific embodiment two: the difference between this embodiment and specific embodiment one is that the rice seedling raising substrate in cold regions is composed of 40 to 60 parts of crushed straw, 10 to 20 parts of fly ash, and 10 to 15 parts of peat in parts by mass. , 10-15 parts of vermiculite and 10-15 parts of perlite. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0017] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that the rice seedling raising substrate in the cold region is composed of 40 to 60 parts of edible fungus slag, 10 to 20 parts of fly ash, 10 to 15 parts by mass. It is made of peat, 10-15 parts of vermiculite and 10-15 parts of perlite. Others are the same as in the first or second embodiment.

Abstract

The invention provides a cold region paddy seedling culture matrix and relates to a paddy seedling culture matrix, and the cold region paddy seedling culture matrix is used for solving the problems of slow seedling emergence of the earlier stage, more irrigation times, serious damping off during the mid-to-late stage of seedling growing and obvious fertilizer removal during the later stage of the seedling when the existing paddy seedling culture matrix is applied in paddy cultivating areas of cold regions. The cold region paddy seedling culture matrix is prepared from edible fungus residues, coal ash, grass carbon, vermiculite and perlite, or ground straw, the coal ash, the grass carbon, the vermiculite and the perlite. The paddy which uses the cold region paddy seedling culture matrix does not need disease preventing and weeding during the seedling culture period, only needs to be irrigated, is convenient to operate, time-saving and labor-saving, has high quality seedlings and stronger stress resistance, no damping off, bacterial wilt and other diseases are caused during the seedling stage, and the seedlings are short and strong, have wide leaves and bright green color. The cold region paddy seedling culture matrix is applied in the paddy field.

Description

technical field [0001] The invention relates to a rice seedling raising substrate. Background technique [0002] In my country, the rice area north of 40 degrees north latitude is usually called the cold area rice cultivation area. Heilongjiang Province is located in the northernmost part of my country and is one of the high latitude rice areas in the world. The rice planting area is 44°20′18.44~50° north latitude 15′1.01, it belongs to the cold area rice cultivation area. The characteristics of rice growth in cold regions are short growth days, less active accumulated temperature, slow warming in the early stage, short high temperature time in the middle stage, rapid cooling in the late stage, and more cold damage from low temperature. [0003] Rice dry-raising and sparse planting technology has played a decisive role in the high and stable yield of rice, but dry-raising seedlings are prone to blight, which requires acid adjustment and disinfection. The technical links suc...
