Rice seedling raising method

Abstract

The invention relates to the technical field of agricultural production, in particular to a rice seedling raising method. The method comprises the following steps of 1, seed treatment, wherein pure and plump seeds are selected to be aired on sunny days for 2-3 days, after being aired, the seeds are soaked and disinfected, and then sterile water is used for rinsing the seeds; 2, seed soaking for accelerating germination, wherein the seeds of which moisture is drained are put into a culture dish, and a germination accelerating agent is sprayed to keep the surfaces of the seeds humid; 3, preparation of seed bed soil, wherein the seed bed soil is composed of pond slit, straw leavening, chitin, medical stone, humic acid, propiconazole, urea, nitrogenous fertilizer and potash fertilizer; 4, seedling raising, wherein the seed bed soil is loaded to a seedling raising disc, the seedling raising disc is put into a seedling raising shed, then buds are sowed in the seedling raising disc, and aftersowing, the seedling raising disc is uniformly covered with soil and thoroughly dripped by water. The rice seedling raising method has the advantages that the disease resistance and germination capability of rice seedlings are improved, and the seedlings are high in survival rate.

Description

technical field

[0001] The invention relates to the technical field of agricultural production, in particular to a rice seedling raising method. Background technique

[0002] Rice is one of the most important food crops in the world, and nearly half of the world's population uses rice as a staple food. my country is a big rice planting country, and the planting area is basically maintained at about 420-450 million mu. According to different methods, rice can be divided into indica rice and japonica rice, early rice and middle-late rice, glutinous rice and non-glutinous rice. There are various ways to eat rice, rice porridge, rice cakes, rice cakes, rice noodles, etc. In addition to being edible, rice can also be used as industrial raw materials for wine making and sugar refining. Rice husks and rice straws also have many uses. However, at present, the survival rate of transplanted rice seedlings cannot be improved as much as possible, the yield is small, and the cultivatio...

Embodiment 1

[0023] A rice seedling raising method, comprising the following steps:

[0024] (1) Seed treatment: choose pure and plump seeds to dry in sunny days for 2 days, turn the seeds every 2 hours during the drying period, soak and disinfect the seeds with strong chlorine solution after drying, and rinse with sterile water for 2-5 and drain the water naturally;

[0025] (2) Seed soaking and accelerating germination: soak the drained seeds in a germination agent with a temperature of 30°C for 25 hours, then remove them and spread them out in a culture vessel, and spray the germination agent to keep the surface of the seeds moist until 90% of the seeds When the long buds of 0.3cm grow out, the seeds are spread out and dried to obtain the rice buds; 0.2 parts of tea polyphenols, 2 parts of vitamin C, and 400 parts of water.

[0026] (3) Making seedbed soil: the pond mud is dried and broken through a 30-mesh sieve as the seedbed soil base material, and the seedbed soil is composed of t...

[0029] A rice seedling raising method, comprising the following steps:

[0030] (1) Seed treatment: choose pure and plump seeds to dry in sunny days for 3 days, turn the seeds every 3 hours during the drying period, soak and disinfect the seeds with strong chlorine solution after drying, and rinse with sterile water for 2-5 days and drain the water naturally;

[0031] (2) Seed soaking and accelerating germination: soak the drained seeds in a germination agent with a temperature of 40°C for 40 hours, then remove them and spread them out in a culture vessel, and spray the germination agent to keep the surface of the seeds moist until 98% of the seeds When growing 1 cm long buds, the seeds are spread out and dried to obtain rice bud seeds; the germination agent consists of the following raw materials in parts by weight: 0.2 parts of cyanamide, 4 parts of ammonium molybdate, 4 parts of ferric diamine fulvic acid , 0.3 parts of tea polyphenols, 5 parts of vitamin C, and 600 parts ...
