Embodiment Construction

[0026] A rice factory seedling raising method, comprising the following steps:

[0027] (1) Seed drying: choose sunny weather before seed selection, spread the seeds 6cm thick in a dry place in the leeward direction, and dry the seeds for 2 days;

[0028] (2) Seed selection: Pour the seeds into 20% salt water and stir thoroughly, rinse the grains, remove the sunken plump seeds, and then wash them with water for 23 times;

[0029] (3) Seed soaking: Soak the selected seeds in the rice soaking solution for 12 hours, so that the seeds can absorb enough water, and the moisture content is controlled at 25%;

[0030] (4) Broken chest: Soak the seeds that have absorbed enough water in warm water at 55°C for 35 minutes, then put them into the chest-broken chamber and keep the temperature at 38°C, let the seeds burst into the chest. At this stage, special attention should be paid to its temperature to prevent high-temperature burning of buds. The lowest germination temperature is 10-12...

Abstract

The invention discloses an industrial rice seedling raising method. The method comprises the steps of seed drying, seed selection, seed soaking, seed breaking, seedling growing, sowing, delivery of the seedlings to a land and the like. According to the method, since rice seeds are socked in self-made rice seed soaking liquid, a very good sterilization and disinfection effect can be achieved, diseases and insect pests can be prevented, development of root systems of the seedlings is promoted, and the bud ratio of the seeds is increased; due to the fact that the rice seeds are covered with uniform nutrient soil rich in nutrition, various nutrients required by emergence of the rice seeds can be provided, propagation of soil-borne diseases is suppressed, quick growth of the rice seeds is promoted, and the seedling growing period is shortened. The quality of the seedlings produced through the method is higher than that of seedlings produced through a traditional seedling growing method, the root systems of the seedlings are developed, the seedlings are robust, the quantity of diseases and insect pests in the seedling stage is small, the emergence rate is high, seedling growing cost is lowered remarkably, and therefore the method is suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to an industrial rice seedling raising method, which belongs to the technical field of agricultural cultivation. Background technique [0002] 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 industrialized seedling raising is the key to reducing labor intensity and accelerating the development of machine-transplanted rice seedlings, and it is also a key link to realize the mechanization of rice production. At present, most of the main rice producing areas in our province have built industrial seedling-raising greenhouses. Although they have effectively promoted the increase in grain production, there have been some new problems that need to be solved urgently. The existing seedling raising...
