Problems solved by technology

[0006] The production of domestic selenium-enriched rice mainly has three kinds of ways at present: the one, spray selenate solution on the foliage at the heading stage or the filling stage, but this method directly contacts selenate solution through rice ear, and the content of bound selenium in the rice is low, There are obvious toxic effects on organisms, and the safety is relatively poor; the second is to spray a large amount of inorganic selenium solutions such as selenate in the paddy field soil. The use of inorganic selenium solution seriously pollutes the soil environment; the third is to plant directly in natural selenium-rich areas. This method is difficult to quantify and control the selenium content, and there are regional limitations, which is not conducive to large-scale standardized production in different places

Embodiment 1

[0028] A planting method for improving anthocyanins in black rice, comprising the following steps:

[0029] (1) Seed treatment period: sun-dry the black rice seeds for disinfection, dry them in the sun for 2 days at 8:00-18:00 on a sunny day, and turn them every 1 hour. The solution is soaked at normal temperature for 48h, and the amount of sodium selenate used per 100g of dry black rice seeds is 1.3mg. The sodium selenate solution submerges the rice seeds and is 10cm higher than the rice seeds. After taking it out, it accelerates germination and sows;

[0030] (2) Seedling stage: When the seedling grows to 2 leaves and 1 heart, choose a sunny day at 16:00 in the afternoon to spray 100mg / L sodium selenate solution on the seedling, the spraying amount per mu is 5500mL, and then ventilate and harden the seedling;

[0031] (3) Paddy field management: According to the conventional planting density and method, plant the seedlings in the paddy field, spray 100mg / L sodium selenate so...

Embodiment 2

[0035] A planting method for improving anthocyanins in black rice, comprising the following steps:

[0036] (1) Seed treatment period: Sun-dry the black rice seeds for disinfection, dry them in the sun for 3 days at 8:00-18:00 on a sunny day, turn them over every 1 hour, the thickness of the seeds when they are dried is 8-15cm, and then use sodium selenate The solution is soaked at normal temperature for 48 hours, and the amount of sodium selenate used per 100 g of dry black rice seeds is 1.5 mg. The sodium selenate solution submerges the rice seeds and is 10 cm higher than the rice seeds. After taking it out, it accelerates germination and sows;

[0037] (2) Seedling stage: When the seedling grows to 2 leaves and 1 heart, choose a sunny day at 18:00 in the afternoon to spray 100mg / L sodium selenate solution on the seedling, the spraying amount per mu is 5000mL, and then ventilate and harden the seedling;

[0038] (3) Paddy field management: According to the conventional plant...

Embodiment 3

[0042] A planting method for improving anthocyanins in black rice, comprising the following steps:

[0043] (1) Seed treatment period: sun-dry the black rice seeds for disinfection, dry them in the sun for 2 days at 8:00-18:00 on a sunny day, and turn them every 1 hour. The solution is soaked at normal temperature for 48h, and the amount of sodium selenate used per 100g of dry black rice seeds is 1.4mg. The sodium selenate solution submerges the rice seeds and is 10cm higher than the rice seeds. After taking it out, it accelerates germination and sows;

[0044] (2) Seedling stage: When the seedling grows to 2 leaves and 1 heart, choose a sunny day at 17:00 in the afternoon to spray 100mg / L sodium selenate solution on the seedling, the spraying amount per mu is 5300mL, and then ventilate and harden the seedling;

[0045] (3) Paddy field management: According to the conventional planting density and method, plant the seedlings in the paddy field, spray 100mg / L sodium selenate so...

Abstract

The invention provides a planting method for increasing anthocyanin in black rice. The planting method includes: using a selenate solution in a seed treatment period, a seedling period, a tillering period, an elongation period and a booting period. The black rice planted by the method is high in anthocyanin content; through rice stalk absorption, the rice is enabled to reach selenium-enriched level, content of all selenium and macromolecular combined selenium in the black rice is increased, and the black rice is high in nutrient content.

Description

technical field [0001] The invention belongs to the field of crop planting, and in particular relates to a planting method for increasing anthocyanins in black rice. Background technique [0002] The seed coat of black rice contains natural anthocyanins. Anthocyanins are a kind of water-soluble flavonoids, which have anti-oxidation and anti-arteriosclerosis effects, can regulate the immune function of the human body, and prevent cardiovascular and cerebrovascular diseases. Therefore, increasing the content of anthocyanins is of great significance to the improvement of the nutritional value of black rice. [0003] With the improvement of people's living standards, agricultural production is changing from a single high-yield goal to high-quality high-yield. As an essential trace element for the human body, selenium is the active center of glutathione peroxidase (GSH-Px) and one of the important indicators of crop quality. Adequate intake of selenium can not only prevent sele...
