Embodiment 1

[0023] A rice seedling raising method, which is based on the dry seedling raising method, and at least includes the steps of seedling field selection, bed soil configuration, and sowing, wherein the bed soil configuration step includes the following content:

[0024] A, carry out soil conditioning to the seedling field of selection: configure the acid solution that concentration is 0.32% and spray the dose of 0.5g per square meter of field area of ​​seedling field, spray, guarantee that the pH value of seedling field soil is between 5;

[0025] B. Configure bed soil and bed soil composition: Lay according to the ratio of the number of seedlings to the area of ​​the bed soil at 2:1, and the thickness of the bed soil is 3cm, where the unit of the bed soil area is cm2, and the unit of the number of seedlings is one, and then configure the nutrition Components, and sprinkled in the bed soil, wherein the nutrient components and concentrations are 3.2% of organic fertilizer, 1.2% of ...

Embodiment 2

[0035] A rice seedling raising method, which is based on the dry seedling raising method, and at least includes the steps of seedling field selection, bed soil configuration, and sowing, wherein the bed soil configuration step includes the following content:

[0036] A, carry out soil conditioning to the seedling field of selection: configure the acid solution that concentration is 0.32% and spray the dose of 0.5g per square meter of seedling field area, spray, guarantee the pH value of seedling field soil between 4.7;

Abstract

The invention relates to the technical field of crop seedling cultivation, in particular to a rice seedling raising method. The method is based on a dry seedling raising mode and at least comprises the steps of rice field selection, bed soil preparation and sowing, wherein the bed soil preparation step comprises the steps that soil adjustment is conducted on a selected rice field, bed soil and bedsoil components are prepared, and the softness of the bed soil is adjusted. The method has the advantages that the rice seedling field soil is configured into an acidic environment, rice seeds are quick in water-absorbing and sprouting, the physiological function is vigorous, the development of rhizoctonia solani can be inhibited, the seedling resistance is enhanced, and the seedling age of the seedlings is shortened; by setting the laying area and thickness of the bed soil, the seedling raising efficiency in the unit area is improved, the nutrient competition among seedlings is reduced, andit is ensured that the seedlings can accept nutrients evenly; nutrients in the bed soil can meet the nutritional requirements of the seedlings during growth; meanwhile, ethyl acetate can dissolve metal components in the bed soil, so that the risk of metal pollution of the seedlings is reduced.

Description

technical field [0001] The invention relates to the technical field of crop seedling raising, in particular to a rice seedling raising method. Background technique [0002] Paddy rice is a cereal crop belonging to Oryza genus, and the representative species is rice. Rice is native to China and India, and was cultivated by the ancestors of the Yangtze River Basin in China 7,000 years ago. Rice is divided into indica rice and japonica rice, early rice and middle and late rice, glutinous rice and non-glutinous rice according to rice type. There are other classifications, which are divided into paddy field rice and floating rice according to whether it is cultivated without soil; divided into seasonal rice and "lazy rice" (regenerated rice) according to the life cycle; divided into ordinary rice and giant rice of about 2 meters according to height. Rice; divided into ordinary fresh rice and "sea rice" according to salt tolerance (in fact, it mainly uses fresh water). The frui...
