Embodiment 1

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

[0051] Specific steps are as follows:

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

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

[0054] 3) According to the way of raising rice seedlings, sowing, mulching and water injection;

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

Embodiment 1

[0057] Example 1: According to the amount of seedling transplanting in 2 acres of field, the zinc content was tested after the final harvest of rice by conventional seedling raising and mechanical transplanting;

Embodiment 2-7

[0058] Example 2-7: According to the amount of seedling transplanting in 2 acres of field, the nursery soil and the zinc-rich nutrient (calculated by the weight of zinc) were respectively in weight ratios of 1000:1, 1000:2, 1000:4, 1000:6, 1000: 8, 1000:10 mix uniformly, then follow the routine operation until the rice is harvested, and detect the zinc content of the rice.

[0059] The ratios used in Examples 8, 9, 10, and 11 are the same as in Example 7.

[0060] The final results obtained in the above examples are shown in the following table:

[0061] Example Weight ratio of nursery soil to zinc-rich nutrient (based on zinc weight) Rice zinc content (mg / kg) Example 1 1000:014.4 Example 2 1000:118.2 Example 3 1000:221.3 Example 4 1000:425.4 Example 5 1000:626.1 Example 6 1000:826.9 Example 7 1000:1027.5 Example 8 1000:1026.5 Example 9 1000:1027.0 Example 10 1000:1026.8 Example 11 1000:1027.1

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 specifically relates to a zinc-rich nutrient for rice, its preparation and a method for producing zinc-rich rice. Background technique [0002] Approximately two-thirds of my country's residents use 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 country's food crops, and the distribution area is vast. Due to population pressure and other reasons, my country’s rice production in the past paid great attention to yield and ignored the quality of rice. Today, with the gradual improvement of living standards, people’s demand for balanced nutrition is increasing, which has made the nutritional quality of rice also more important in recent years. More and more attention. [0003] Zinc, the element symbol Zn, is the fourth most common metal and one of the essential micronutrient elements in the human body. Its content in th...
