Embodiment 1

[0019] A high-yield planting method of organic selenium-enriched rice, comprising the following steps:

[0020] A: Seed selection and disinfection: choose full-grained rice seeds, dry them in the sun, soak them with Tripterygium wilfordii extract for 3 hours at a material-to-liquid ratio of 1:2, remove and drain the water after soaking, and then press them with 0.1% sodium selenate solution Liquid ratio 1: 1.3 Soaked for 2 hours, then fished out and dried to obtain sterilized rice seeds, and set aside; wherein, the tripterygium wilfordii extract was prepared according to the following method: Tripterygium wilfordii was crushed to 80 mesh, and the ratio of material to liquid was 1:15. Add water, soak for 10 hours, filter to remove residue, and obtain Tripterygium wilfordii extract;

[0021] B: Seedling field finishing: choose a flat land as the seedling field, choose a sunny period, expose the seedling field to the sun for 2-3 days after plowing, and apply bio-organic fertilize...

Embodiment 2

[0034] A high-yield planting method of organic selenium-enriched rice, comprising the following steps:

[0035] A: Seed selection and disinfection: select full-grained rice seeds, dry them in the sun, soak them with Tripterygium wilfordii extract for 4 hours at a ratio of material to liquid 1:2, remove and drain the water after soaking, and then press them with 0.1% sodium selenate solution After soaking for 2 hours at a liquid ratio of 1:1.3, remove and dry to obtain sterilized rice seeds and set aside; wherein the tripterygium wilfordii extract is prepared by the following method: tripterygium wilfordii is crushed to 80 mesh, and added according to a material-to-liquid ratio of 1:25 Soak in clear water for 15 hours, filter to remove slag, and obtain Tripterygium wilfordii extract;

[0036] B: Seedling field finishing: choose a flat land as the seedling field, choose a sunny period, expose the seedling field to the sun for 2-3 days after plowing, and apply bio-organic fertili...

Embodiment 3

[0048] A: Seed selection and disinfection: choose full-grained rice seeds, dry them in the sun, soak them with Tripterygium wilfordii extract at a material-to-liquid ratio of 1:2 for 5 hours, remove and drain the water after soaking, and then press them with 0.1% sodium selenate solution After soaking for 2 hours at a liquid ratio of 1:1.3, remove and dry to obtain sterilized rice seeds and set aside; wherein the tripterygium wilfordii extract is prepared by the following method: tripterygium wilfordii is crushed to 80 mesh, and added according to a material-to-liquid ratio of 1:25 Soak in clear water for 15 hours, filter to remove slag, and obtain Tripterygium wilfordii extract;

[0049] B: Seedling field finishing: choose a flat land as the seedling field, choose a sunny period, expose the seedling field to the sun for 2-3 days after plowing, and apply bio-organic fertilizer 3kg / m 2 , leveling the ground, spraying and watering, making the soil moisture content 30%-40%, spray...

Abstract

The present invention belongs to the field of agricultural cultivation technology, and particularly relates to a high-yield cultivation method of organic selenium-enriched rice. The method includes the following steps: A, selecting rice seeds and sterilizing the rice seeds; B, arranging rice seedling beds; C, sowing the rice seeds and cultivating rice seedlings; D, preparing a large field; E, transplanting the rice seedlings; F, managing the field; and J, harvesting the rice. Insect disinfestation for the rice seeds is carried out using Tripterygium wilfordii extracts; meanwhile, Tripterygium wilfordii extracts are used to dissolve the selenium and biological pesticides in the rice production process, and further improvements on the prevention and control of plant diseases and insect pests are realized in the overall growth process of the organic selenium-enriched rice. Instead of chemical fertilizers, bio-organic fertilizers are used in the rice cultivating process, which ensures a variety of nutrients required in the rice cultivating process and improves the rice yields. The rice yields and the selenium content of the organic selenium-enriched rice are higher than those of rice planted with traditional cultivation technology, and pesticide residues are significantly lower than that of the rice planted with the traditional cultivation technology.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a high-yield planting method of organic selenium-enriched rice. Background technique [0002] Rice is the main food crop in my country, and rice is the staple food in the middle and lower reaches of the Yangtze River, the southeast coastal areas and some Heilongjiang areas. my country has a large population, a large demand for rice, and a large per capita consumption. In recent years, there have been many problematic rice, such as the poisonous cadmium rice in Hunan, which has sounded the alarm for people on the food safety of rice staple food. At the same time, with the improvement of people's living standards, people have higher and higher requirements for food nutrition and safety. Due to the uncontrolled use of pesticides and fertilizers in the production process of ordinary rice products, the food safety performance of ordinary rice cannot be effec...
