High-emergence-rate intelligent factory rice seedling raising method and system

Abstract

The invention discloses a high-emergence-rate intelligent factory rice seedling raising method. The method comprises the following steps: selecting seeds, and soaking the selected rice seeds in a seedsoaking device at the room temperature; preparing a seedling raising substrate, and stirring and mixing field soil and nutrient soil to form a seedling raising substrate; laying the seedling raisingsubstrate and the soaked rice seeds in a seedling raising tray; putting the seedling raising plate into a darkening chamber to promote the rice seeds to germinate, and setting the temperature of the darkening chamber to be 26-28 DEG C, the humidity to be 30-40% and the darkening time to be 48 hours; and moving the seedling raising plate out of the darkening chamber, airing the seedlings in a sunshade for 6-8 hours, then putting the seedlings into an open-air seedling pool for seedling management, and transplanting the seedlings after the seedlings naturally grow for 18-20 days. The high-emergence-rate intelligent factory rice seedling raising method disclosed by the invention performs accelerating germination by adopting the darkening chamber, the humidity and temperature are accurately controlled, the budding time is controlled to be 48 hours and is shortened by nearly half compared with 3-4 days of a traditional method, the budding rate is increased to 95% or above from 85% of traditional seedling raising methods, seedlings are neat and consistent in height, labor and cost are saved, the crop yield is greatly increased, and plant diseases and insect pests are reduced.

Description

technical field [0001] The invention belongs to the technical field of rice seedling raising, and in particular relates to a method and system for raising rice seedlings in a smart factory with a high emergence rate. Background technique [0002] At present, the way of rice production relying on natural conditions still accounts for the vast majority. As a result, the rice yield per unit of land is low, more land is occupied, and grain production is greatly affected by natural conditions. As the area of ​​cultivated land gradually decreases, the total domestic rice output decreases, and how to increase the output per unit area of ​​land becomes particularly important. [0003] Industrial rice seedling raising is a production method that uses modern agricultural equipment for intensive seedling raising. It integrates mechatronics, standardization, and automatic control. It is a technology that combines modern agricultural engineering and agronomy. The technology of industria...

Problems solved by technology

[0004] The technical problems solved by the present invention: low germination rate and many diseases lead to poor seedling quality in the later stage, low seedling emergence rate, not strong and straight seedling growth, easy occurrence of plant diseases and insect pests in the seedling stage directly leads to low yield, etc., and the cost is high, and large-scale production cannot be carried out.
