Problems solved by technology

At present, methods to increase zinc content in rice can be roughly divided into two categories. One is to cultivate rice varieties that can be enriched in zinc in the endosperm through genetic technology, but this method often leads to the reduction of stress resistance of rice and brings potential health risks; the second is to strengthen the zinc content in rice through agricultural fertilization measures
At present, the commonly used zinc fertilizer is mainly zinc sulfate, but in the existing methods or researches, the number of times of spraying zinc fertilizer is relatively large, and the amount is relatively large. If it is necessary to spray once every 10-15 days
Not only the required labor costs are high, but also the risk of environmental pollution

Embodiment 1

[0026] Apply basal fertilizer to the field before sowing. In this embodiment, the species tested is Huanghuazhan, which is sown after the base fertilizer is applied, and then the seedlings are transplanted. The transplanting density of seedlings is 15,000-18,000 holes per mu, 3-4 holes per hole. During the whole growth period of rice, a large amount of inorganic chemical fertilizers, herbicides and pesticides are not applied. Arrange insect-proof lamps in the field to repel insects, and the entire field weeding work is carried out manually. Seed treatment, seedling raising, soil preparation, transplanting and other processes are all conventional rice planting processes.

[0027] Prepare zinc fertilizer: take sugar alcohol chelated zinc fertilizer, mix sugar alcohol chelated zinc fertilizer with water evenly to make sugar alcohol chelated zinc fertilizer solution, wherein, the volume ratio of sugar alcohol chelated zinc fertilizer mixed with water is 0.1 -0.3:100.

Embodiment 2

[0040] Apply basal fertilizer to the field before sowing. In this embodiment, the species tested is Huanghuazhan, which is sown after the base fertilizer is applied, and then the seedlings are transplanted. The transplanting density of seedlings is 15,000-18,000 holes per mu, 3-4 holes per hole. During the whole growth period of rice, no large amount of elemental inorganic fertilizers are applied, herbicides are not sprayed, and pesticides are not used. Insect-proof lamps are arranged in the field to repel insects, and the entire field weeding work is carried out manually. Seed treatment, seedling raising, soil preparation, transplanting and other processes are all conventional rice planting processes.

Abstract

The invention provides a method for planting zinc-rich rice, comprising the following steps: transplanting rice seedlings after sowing, and spraying zinc added with Bacillus atrophaeus microbiota to the leaves during the booting stage, early stage of filling and late stage of rice growth respectively. Fertilizer, the zinc fertilizer is a sugar alcohol chelated zinc fertilizer, and the irrigation of the paddy rice adopts a controlled irrigation mode during the whole growth period of the paddy rice. The invention has simple operation and low cost, and the content of zinc element in the planted rice is greatly increased, and is suitable for popularizing planting.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for planting zinc-rich rice. Background technique [0002] Zinc is an essential trace element for human life activities and is inseparable from human health problems. Existing studies have confirmed that there are four aspects to the impact of zinc on human health. One is to participate in important physiological and biochemical reactions of living organisms such as protein, nucleic acid synthesis, and substance metabolism as a component or activator of various enzymes; the other is to directly act on it. In the synthesis and secretion of growth hormone, promote the growth and development of the human body; the third is to inhibit fat peroxidation or thiol oxidation, enhance the resistance of biofilms, and then improve the digestive function of the human body, anti-cancer, anti-aging; the fourth is to regulate the immune mechanism of the human b...
