Embodiment 1

[0050] In a rice planting base in Jiangsu, zinc-enriched rice was cultivated according to the method of raising seedlings in seedling trays, and a total of 9 groups of seedlings were cultivated.

[0051] Specific steps are as follows:

[0052] 1) Before the seedling soil is placed on the plate, the seedling soil is mixed with the zinc-rich nutrient, and the weight ratio of the zinc-rich nutrient to the seedling soil is 0.1-10:1000 based on the weight of zinc.

[0053] 2) Put the seedling soil mixed with zinc-rich nutrient into the seedling tray;

[0054] 3) According to the rice seedling raising method, sowing, film covering and water injection are carried out;

[0055] 4) After the seedlings are raised, transplant the seedlings to the field mechanically or manually, and finally harvest the zinc-rich rice.

Embodiment 1

[0057] Embodiment 1: According to the dosage of transplanting rice seedlings in 2 mu of fields, with conventional seedling raising and mechanical transplanting, the zinc content is detected after the rice is finally harvested;

Embodiment 2-7

[0058] Example 2-7: According to the amount of seedling transplanting in 2 acres of field, the seedling soil and zinc-enriched nutrient (calculated by the weight of zinc) are respectively according to the weight ratio of 1000:1, 1000:2, 1000:4, 1000:6, 1000: 8. Mix 1000:10 evenly, and then operate as usual until the rice is harvested, and the zinc content of the rice is detected.

[0059] Embodiment 8,9,10,11 used ratio is the same as embodiment 7.

[0060] The final result obtained by the above-mentioned embodiment is shown in the table below:

Abstract

The invention discloses a zinc-rich nutrient for rice, a preparation method thereof and a method for producing zinc-rich rice with the nutrient. The zinc-rich nutrient comprises the following components in parts by weight: 0.5-25.5 parts of a zinc source by zinc weight, 0.3-1.8 parts of bio-organic fertilizer, 1.8-2.5 parts of humic acid and 0.01-0.05 part of a fertilizer binding agent. The zinc-rich nutrient is applied in the rice planting process. The rice produced by the method has the zinc content of 18.2-27.5 mg / kg and can be directly cooked or processed into other rice products to be eaten.

Description

technical field [0001] The invention belongs to the field of crop planting, and in particular relates to a zinc-enriched nutrient for rice, its preparation and a method for producing zinc-enriched rice. Background technique [0002] About two-thirds of the residents in my country take rice as their staple food. As one of the most important food crops in my country, the planting area of ​​rice accounts for half of the planting area of ​​food crops in my country, and the distribution area is vast. Due to population pressure, etc., in the past rice production, our country paid great attention to the output and ignored the quality of rice. Today, with the gradual improvement of living standards, people's demand for nutritional balance is getting higher and higher, which makes the nutritional quality of rice in recent years. more and more attention. [0003] Zinc, element symbol Zn, is the fourth most common metal and one of the essential micronutrient elements for the human bod...
