Embodiment Construction

[0017] In order to further understand the content, features and effects of the present invention, the following examples are given, and detailed descriptions are given below with reference to the accompanying drawings.

[0018] see figure 1 :

[0019] The invention relates to a seedling raising method of rice seedbeds in cold regions. Before seedling raising, mechanically pulverized crop straw and rice husks with a thickness of 15-20 cm are spread on the seedling bed, and EM active liquid is used to ferment to form an isolation and temperature-increasing layer, and the seedlings are raised in trays on the seedling bed.

[0020] Further, the method for raising seedlings in the interlayer of the rice seedbed in the cold region, the specific method is:

[0021] S101, collecting the crop stalks in the field and the rice husks produced during rice processing, and drying to remove moisture for later use;

[0022] S102. Choose a standardized seedling field as the seedbed, place the...

Abstract

The invention discloses a method for interlayer seedling cultivation on a rice seedbed in a cold region. The method comprises the following steps: before seedling cultivation, paving mechanically-crushed crop straws and rice husks which are 15-20 cm in thickness on the seedbed, fermenting by utilizing an EM active liquid to form an isolated warming layer and performing wobble-plate seedling cultivation on the seedbed. According to the method disclosed by the invention, aiming at the problems of low temperature during the rice seedling cultivation in the cold region, poor seed seedling emergence, irregular seedling emergence and the like, the mechanically-crushed crop straws and rice husks are paved on the seedbed; the isolated warming layer is formed by utilizing the EM active liquid formed by various microorganisms belonging to three floras like photosynthetic bacteria, lactic acid bacteria and saccharomycetes, so that the seedbed soil temperature is improved; as the wobble-plate seedling cultivation is performed on the seedbed, the problem of poor seed seedling emergence caused by low soil temperature during seedling cultivation is favorably solved, and the normal growth and development of seedlings is ensured; an isolation layer after fermentation can also be taken as a rice compost for field production, so that the application of chemical fertilizers can be reduced.

Description

technical field [0001] The invention belongs to the field of rice seedling raising, and in particular relates to a method for raising seedlings in interlayers of rice seedbeds in cold regions. Background technique [0002] Improving the emergence rate of seeds and rationally cultivating strong seedlings are the key to the development of machine-transplanted rice seedlings. At present, there are mainly problems in rice machine-transplanted seedling raising in my country, such as large seedling amount, poor seed emergence, irregular seedling emergence, small elasticity of seedling age, and poor quality of seedlings. Rice in Heilongjiang, Jilin and other cold areas in Northeast my country has special conditions for rice growth compared with other rice areas. First, the time suitable for rice growth and development is short, the active accumulated temperature is small, the temperature rises slowly in the early stage, the high temperature time in the middle stage is short, and th...
