Embodiment 1

[0048] Embodiment 1: Cultivate according to normal rice seedling raising, transplanting, paddy field management;

Embodiment 2-32

[0049] Example 2-32: At different stages of rice, different amounts of the zinc-enriched nutrient for rice of the present invention were applied, and the remaining zinc-enriched rice was cultivated in the same way as the control group.

[0050] method one:

[0051] 1) Applying the zinc-enriched nutrient for rice at the same time when the base fertilizer is applied to the rice, the amount of the zinc-enriched nutrient for rice is 2-20 kg / mu in terms of the weight of zinc;

[0052] 2) Carry out water and fertilizer management according to conventional rice planting methods, and finally harvest zinc-rich rice.

[0053] Method Two:

[0054] 1) At any one of the tillering and jointing stage, booting stage or filling stage or any combination thereof during the rice growth process, the zinc-enriched nutrient for rice is applied to the paddy field, and the amount of the zinc-enriched nutrient for rice is The weight of zinc is 2~16kg / mu;

[0055] 2) Carry out water and fertilizer ma...

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 for rice comprises the following components in parts by weight: 0.5-25.5 parts of a zinc source by zinc weight, 6.5-9.2 parts of bio-organic fertilizer, 0.05-0.15 part of ferrous sulfate, 0.33-4.8 parts of an acid-base buffer agent 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 14.6-40.2 mg / kg, meets the requirements of the national food standard, maintains the original nutrients while achieving the zinc-rich aim, has good physiological activity and is easy to digest and absorb.

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...
