Example Embodiment

[0024] Example 1

[0025] A method for planting selenium-rich rice includes the following steps:

[0026] S1. Paddy field pretreatment: select the fields planted with milk vetch, carry out pressing, irrigation, retting, rotary tillage and rake leveling, and ridging. Among them, during the pressing process, the pressing depth is 15 cm, and the pressing amount is 3500kg / mu; in the process of irrigation, irrigate to a depth of 15cm, then retort for 40 days;

[0027] During the period from the green to the first flowering of Chinese milk vetch, spray an aqueous solution of organic selenium fertilizer with a spraying amount of 160 kg / mu. The weight ratio of organic selenium fertilizer to water is 1:600, and the selenium content in organic selenium fertilizer is 0.1 mg / mu. kg;

[0028] S2. Seedling transplanting: After the pretreatment of the rice field, keep the water depth of the rice field at 10cm, set a frequency-vibration insecticidal lamp per mu of rice field, and plant the seedlings...

Abstract

The invention discloses a selenium-enriched rice planting method. The method comprises the following steps: S1, pretreating a rice field; S2, transplanting rice seedlings; S3, fertilizing during tillering: 7-9 days after transplanting the seedlings, keeping the water depth in the rice field to be 8-10 cm, and applying 100-120 kg of a mixed fertilizer per mu, wherein the mixed fertilizer includes the following raw materials in parts by weight: 100-165 parts of an organic fertilizer, 60-90 parts of an inorganic fertilizer, 3-5 parts of chitosan, 8-12 parts of croton powder, and 15-25 parts of a coating material; S4, fertilizing during full heading: after the seedlings are full in heading, keeping the water depth in the rice field to be 8-10 cm, dressing 3-4 kg of urea per mu, and spraying 40-180 kg of an aqueous solution of an organic selenium fertilizer per mu, wherein the weight ratio of the organic selenium fertilizer to water is 1: (400-600); the content of selenium in the organic selenium fertilizer is 0.1-0.3 mg/kg; S5, harvesting. The rice planted by adopting the method provided by the invention is high in selenium content and good in quality.

Description

technical field [0001] The invention relates to the technical field of rice planting, in particular to a method for planting selenium-enriched rice. Background technique [0002] Selenium is a very important trace element in the ecological environment. It is now medically proven that selenium deficiency is related to various diseases. 72% of my country's regions are in selenium-deficient and low-selenium belts. The lack of selenium in the soil has caused the general lack of selenium nutrition in my country's agriculture and animal husbandry. Therefore, the selenium content in people's food is low, and the lack of selenium intake seriously affects people's health. . [0003] There are two ways for the human body to supplement selenium: one is to take inorganic selenium directly; the other is to eat more foods or drinks rich in organic selenium. Inorganic selenium has a low absorption rate and has certain toxicity. Selenium supplement products on the market include selenometh...
