Problems solved by technology

[0005] In the prior art, the selenium content in rice is increased by spraying sodium selenite during the rice growth period, but there is poor absorption by rice, and the selenium content in rice will be insufficient if the spraying amount is small, and the rice will die and yield will be reduced if the spraying amount is large and other technical difficulties restrict the production of selenium-enriched rice
[0006] However, the research on selenium-enriched and zinc rice has not been reported yet.

example 1

[0048] 1. Preparation of selenium fertilizer and zinc fertilizer

[0049] Sodium Selenite 4 kg

[0050] Zinc sulfate 1 kg

[0051] 2. Application method

[0052] In Jinwanxiang 1 and Genza "Xiuyou 5" rice, the young panicle differentiation stage, the full ear stage of rice, the flowering stage and the filling period of rice are divided into three times, and a large ultra-low particle mist machine is used to select useful shade. After four o'clock in the afternoon or in the afternoon (to prevent direct sunlight and affect fertilizer efficiency), generally in mid-September, hyperosmotic additives can also be added when spraying leaves, and high-concentration selenium fertilizers and zinc fertilizers (total weight) can be sprayed per acre. 58 grams, mixed with 50 kilograms of water, spray evenly, the amount of selenium and zinc fertilizer is 60 grams per mu each time, and environmental protection, low toxicity and pollution-free fertilizers and pesticides should be selected dur...

Abstract

The present invention discloses a kind of nutritious rice with rich organic selenium and zinc and its production method. The nutritious rice with rich organic selenium and zinc has organic selenium content of 0.16-1.12 mg / kg and zinc content of 0.5-1.5 mg / kg. The nutritious rice with rich organic selenium and zinc is made of paddy with rich organic selenium and zinc, and the paddy with rich organic selenium and zinc is produced through applying selenium and zinc enriched fertilizer compounded with selenite, zinc fertilizer, organic nitrogen fertilizer, phosphate fertilizer and potash fertilizer and multifunctional trace elements during paddy growth.

Description

technical field [0001] The invention belongs to a kind of rice, in particular to a kind of rice rich in nutrient elements and a production method thereof. Background technique [0002] Selenium is one of the essential nutritional elements for human body and animals. The Chinese Nutrition Society lists selenium as one of the 15 daily dietary essential elements. Modern medical research has confirmed that selenium has a variety of physiological functions, and the main source of selenium in the body is food. Selenium in natural foods alone is not enough to meet the normal requirements of the human body. To ensure human health and prevent and treat related diseases, there should be sufficient selenium intake. Especially when there are no specific medicines for many diseases such as cancer and viral diseases, it is particularly important to prevent the occurrence of various diseases by taking enough selenium. However, inorganic selenium is highly toxic, and it is imperative to ...
