Problems solved by technology

Improving and cultivating zinc-rich wheat varieties through genetic breeding is a one-and-done cause for improving the nutritional value of wheat zinc, and it is also a long-term work with broad development prospects; but it is a long-term systematic project, and wheat varieties have Certain regional adaptability, as far as the current research progress is concerned, it is still too early to be popularized and applied, and the problem of zinc nutrition deficiency cannot be solved to the greatest extent; Nutritional function of wheat will become a reality
The cultivation of zinc-rich wheat through transgenic technology has made significant progress, but the safety debate of genetically modified food seems to be inconclusive, and there are still many obstacles to the promotion and application of genetically modified wheat
[0008] As for the improvement of wheat zinc nutritional status through wheat zinc-enriched cultivation technology, using the existing popularized common wheat varieties, in the process of its growth and development, to improve the nutritional environment, improve the utilization rate of wheat zinc nutrition, and increase the wheat zinc content. At present, there are not many reports on the research. At present, the main research content is mostly the effect of zinc application on wheat yield or the research on preventing zinc deficiency in wheat. At the same time, there are also some studies on increasing the zinc content of crops by spraying zinc fertilizer on the leaves. Strengthening studies are rarely found, but it has been found from a few studies that this zinc-enriching pathway in wheat is still feasible, but the increase in zinc content in wheat is still relatively low, generally not exceeding 50mg / kg

Embodiment 1

[0031] The wheat field in Dingyan Town, Rugao City, Jiangsu Province was selected as the fertilizer effect test field, and the wheat cultivar was Yangmai-16, which is widely planted in the plain area of ​​the lower reaches of the Yangtze River. m = 66 square meters of community, keep a 1-meter isolation distance around each community. Select one of them as the control group of conventional wheat cultivation (do not add the wheat-specific zinc fertilizer of the present invention), and the group that adds the wheat-specific zinc fertilizer of the present invention adopts the same cultivation technique as the control group. When harvesting, gather wheat Grains, the zinc content therein was measured, and the zinc content of the wheat grains of the control group was measured to be 41.5 mg / kg.

Embodiment 2-13

[0033]First, the natural nano material attapulgite powder is modified by heat treatment at 100-200°C, and an appropriate amount of modified attapulgite (0.2-0.4kg) is weighed, and an appropriate amount of sulfur (0.05-0.2kg) is added respectively, After mixing evenly (the specific combination method is weighed according to the table below, and the following mixing and dosage methods are also shown in the table below), ultrafinely pulverize into a powder with a particle size of less than 48 μm, so that the proportion of nano-level is 3~ 25%, for later use; then weigh an appropriate amount of zinc salts such as zinc sulfate, zinc oxide, zinc citrate, and zinc acetate (0.25kg in terms of zinc), grind them into powder, and then add corresponding amounts of attapulgite and sulfur Mix it evenly; finally add an appropriate amount of crushed organic fertilizer (purchased from Jiangyin Changqing Fertilizer Co., Ltd.) (1-2.5kg), mix well and granulate on a disc granulator, disc Spray an...

Embodiment 14-23

[0037] First, the natural nano-material attapulgite powder is modified by heat treatment at 100-200°C, weigh 0.3kg of modified attapulgite, add 0.1kg of sulfur, mix well, and ultrafinely pulverize the particle size to less than 48μm powder, so that the proportion of nano-levels is 3-25%, set aside; then weigh an appropriate amount of zinc sulfate (0.05-2.5kg in terms of zinc), crush it into powder, and then add the corresponding amount of bumps The mixture of bar clay and sulfur, mix it evenly; finally add 1.5kg of crushed organic fertilizer (purchased from Jiangyin Changqing Fertilizer Industry Co., Ltd.) powder, mix well and granulate on a disc granulator, disc Spray an appropriate amount of fertilizer binder during granulation (the amount of fertilizer binder is 0.5% of the total weight of the prepared wheat-specific zinc fertilizer), pack it into bags (each bag contains 0.05-2.5kg of zinc), seal and affix the ingredient label ,spare.

Abstract

The invention discloses a specific zinc fertilizer for wheat, preparation of the specific zinc fertilizer and a method for producing zinc-rich wheat. The specific zinc fertilizer for wheat comprises the following components in parts by weight: 0.5-25 parts of a zinc source (counted by weight of zinc), 2-4 parts of an adsorbent, 0.5-2 parts of an acid conditioning agent, 10-25 parts of an organic fertilizer and a fertilizer binder, wherein the weight of the fertilizer binder is equal to 0.3%-0.5% of that of the specific zinc fertilizer for the wheat. The specific zinc fertilizer for the wheat is applied in a planting process of the wheat. The wheat produced by utilizing the specific zinc fertilizer and the method has the advantages that the content of the zinc maximally can reach 160mg/kg and is equal to four times of that of the normal wheat, the wheat cultured by utilizing the manner is natural and is rich in zinc, and the absorption and utilization rates of biologic zinc to a human body are high.

Description

technical field [0001] The invention belongs to the field of crop planting, and in particular relates to a special zinc fertilizer for wheat, its preparation and a method for producing zinc-rich wheat. Background technique [0002] Zinc is one of the essential trace elements for the human body. It plays an extremely important role in the growth and development of the human body. It is often hailed as the "flower of life" and "the source of intelligence". Scientists have shown that zinc participates in the metabolic process of more than 80 enzymes in the human body, especially DNA and RNA polymerases, which directly participate in the synthesis of nucleic acid and protein, cell differentiation and proliferation, and many metabolisms. There are also some enzymes in the human body that need zinc. Therefore, zinc is an essential substance in important physiological processes such as human growth and development, reproductive genetics, immune endocrine, nerves, and body fluids. Z...
