Embodiment 1

[0024] A planting method of high-quality selenium-enriched rice, comprising the steps of:

[0025] S1. Paddy field pretreatment: select a field where broad beans are planted, and after picking green broad beans, carry out green pressing, watering, retting, rotary tillage and harrowing, and ridge division, wherein, in the green pressing process, the green pressing depth is 20cm, and pressing The green quantity is 2500kg / mu; in the irrigation process, the water is irrigated to a water depth of 8cm, and then retting is done for 30 days;

[0026] At the early flowering stage of the broad bean, the aqueous solution of organic selenium fertilizer was sprayed at a spray rate of 200 kg / mu, wherein the weight ratio of organic selenium fertilizer to water was 1:600, and the content of selenium in the organic selenium fertilizer was 0.1 mg / kg;

[0027] S2, transplanting: after the paddy field is pretreated, transplant the seedlings, keep the water depth of the paddy field at 11cm, set tw...

Abstract

The invention discloses a planting method for high-quality selenium-rich rice. The method includes the following steps of firstly, preprocessing a rice field, wherein a field where broad beans are planted is selected, and green manuring, irrigation, wet compositing, rotary tillage and harrowing and ridging are conducted after broad beans are picked; secondly, transplanting rice seedlings; thirdly, conducting tillering and fertilizer applying; fourthly, stocking ducks; fifthly, conducting full heading and fertilizer applying, wherein ducks are driven out after full heading is conducted on the seedlings, the water depth of the rice field is kept at 9-11 cm, 1-3 kg of urea, 1-2 kg of potassium metasilicate and 100-280 kg of organic selenium fertilizer aqueous solution are applied in a dressing mode in each mu of field, the weight ratio of organic selenium fertilizer to water is 1 to 500-700, and the selenium content in organic selenium fertilizer is 0.1-0.3 mg / kg; sixthly, conducting harvesting. Planted rice is high in selenium element content, good in quality and high in yield.

Description

technical field [0001] The invention relates to the technical field of rice planting, in particular to a method for planting high-quality 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 inclu...
