Embodiment 1

[0024] A rice seedling raising method comprising the steps of:

[0025] (1) Seedling field selection and seedbed preparation: choose the dry land with smooth ground and convenient irrigation and drainage as the dry land for raising seedlings, make the seedbed by 1m width, surround the seedbed with planks, the end surface of the plank is higher than the seedbed bed surface, cover the seedbed bed surface A layer of wet and soft clay. The clay is taken from the soft soil with a sand content less than 20% at a depth of 5cm in the paddy field. After taking out the clay, add water and stir it into a muddy state. Scrape the clay to a thickness of 5cm and dry it in the sun for 1 day. Until the clay is not sticky to the hands, use the seedling tray mold to print the seedling tray pattern on the surface of the clay that is consistent with the inner surface of the seedling tray, and open water leakage holes in the clay layer, and then use a transparent film to build a rainproof shed, and ...

Embodiment 2

[0031] A rice seedling raising method comprising the steps of:

[0032] (1) Seedling field selection and seedbed preparation: choose the dry land with flat ground and convenient irrigation and drainage as the dry land for raising seedlings, make a seedbed with a width of 1.4m, surround the seedbed with planks, the end surface of the plank is higher than the seedbed bed surface, cover the seedbed bed surface The upper layer is wet and soft clay. The clay is taken from the soft soil with a sand content of less than 20% at a depth of 15cm in the paddy field. After the clay is taken out, add water and stir it into a muddy state. Scrape the clay evenly. The thickness of the clay is 9cm. Let it dry for 2 days , until the clay does not stick to hands, and then use the seedling tray mold to print the seedling tray pattern on the surface of the clay that is consistent with the inner surface of the seedling tray, and open water leakage holes in the clay layer, then build a rainproof shed...

Embodiment 3

[0038] A rice seedling raising method comprising the steps of:

[0039] (1) Seedling field selection and seedbed preparation: choose dry land with flat ground and convenient irrigation and drainage as the dry land for raising seedlings, make a seedbed with a width of 1.2m, surround the seedbed with planks, and the end surface of the plank is higher than the seedbed bed surface, cover the seedbed bed surface The upper layer is wet and soft clay. The clay is taken from the soft soil with a sand content of less than 20% at a depth of 10cm in the paddy field. After taking out the clay, add water and stir it into a muddy state. Scrape the clay to a thickness of 7cm and let it dry for 1 day , until the clay does not stick to hands, and then use the seedling tray mold to print the seedling tray pattern on the surface of the clay that is consistent with the inner surface of the seedling tray, and open water leakage holes in the clay layer, then build a rainproof shed with a transparent...

Abstract

The invention belongs to the technical field of rice planting, in particular to a dry raising method for rice seedlings. The method comprises the following five steps of rice field selection and seedbed preparation, substrate preparation, seed soaking and germination, sowing and rice seedling management. Wood boards surround a seedbed. The upper end surfaces of the word boards are higher than the bed surface of the seedbed. A layer of wet and soft clay covers the bed surface of the seedbed. The clay is scraped flat at the thickness of 5-9cm and sun-dried for 1-2 days till the clay is not sticky on hands. Then, a rice seedling plate mold is utilized for printing seedling plate patterns on the clay surface. The seedling plate patterns are the same as those in the inner surface of a seedling nursery plate. Water leakage holes are arranged in a clay layer. A transparent thin film is utilized for setting up a rain-proof shed. The clay is sun-dried 25-30 days such that the clay is dried to be adobe. The adobe is like the seedling nursery plate. Material is selected on the spot. The manufacture is simple without cost. After transplanting of seedlings, the adobe can be automatically decomposed into mud used for planting crops after the adobe is exposed to the sun and rain. There is no need to recycle. The method is safe without causing pollution.

Description

【Technical field】 [0001] The invention relates to the technical field of rice planting, in particular to a method for raising rice seedlings under dry conditions. 【Background technique】 [0002] Rice machine transplanting is the main development direction of modern rice farming technology in my country. It is of great significance to stabilize grain production, increase rice yield per unit area, promote large-scale rice production, and improve labor productivity under the conditions of rural labor force transfer and aging. With the development of society and economy, the transfer and aging of rural labor force, with the support of policies, rice machine transplanting in my country has developed rapidly. At present, there are mainly dry seedling raising and wet water seedling raising methods in my country. The dry seedling raising method is usually used in the environment of growing seedlings in greenhouses, but whether it is dry seedling raising or wet water seedling raising...
