Problems solved by technology

In previous studies, there are many ways to enrich zinc and iron in crops. Many studies have shown that spraying zinc and iron fertilizers on the leaves can increase the zinc and iron content of rice, but it is difficult to increase the zinc and iron content in rice after reaching a certain level. further increase

Embodiment 1

[0031] The giant embryo rice variety "Fuju No. 1" was used.

[0032] 1) Prepare a seedling bed in a width of 0.8-0.9 meters, and lay a layer of 3-4cm seedling matrix on the seedbed. The seedling matrix is ​​composed of 20 parts by weight of expanded perlite particles, 5 parts by weight of rice bran, and 10 parts by weight of cassava stem crushed chips , 6 parts by weight of sweet potato slag, 8 parts by weight of plant ash, additionally add the imported compound fertilizer of 0.3% of total weight, the actinomycetes solvent of 2.5% of total weight, wherein the effective active bacteria content is 120-130 million units / gram, After mixing and stirring evenly, add water to make the water content reach 73-75%, and make it by composting and fermenting for 65-70 days;

[0033] 2) Put the giant embryo rice seeds in the drying box at 38-39℃ for 2.4-2.6 hours, take them out and dry them indoors for 2 hours, soak the seeds in the zinc-rich seed soaking solution for 40-48 hours, and keep ...

Embodiment 2

[0049] The giant embryo rice variety "Fuji No. 4" was used

[0050] 1) Prepare a seedling bed in a width of 0.8-0.9 meters, and lay a layer of 3-4cm seedling matrix on the seedbed. The seedling matrix is ​​composed of 20 parts by weight of expanded perlite particles, 5 parts by weight of rice bran, and 10 parts by weight of cassava stem crushed chips , 6 parts by weight of sweet potato slag, 8 parts by weight of plant ash, additionally add the imported compound fertilizer of 0.3% of total weight, the actinomycetes solvent of 2.5% of total weight, wherein the effective active bacteria content is 120-130 million units / gram, After mixing and stirring evenly, add water to make the water content reach 73-75%, and make it by composting and fermenting for 65-70 days;

[0051] 2) Put the giant embryo rice seeds in the drying box at 38-39℃ for 2.4-2.6 hours, take them out and dry them indoors for 2 hours, soak the seeds in the zinc-rich seed soaking solution for 40-48 hours, and keep t...

Abstract

The invention relates to a cultivation method for zinc-rich and iron-rich giant embryo rice, in particular to the technical field of rice cultivation. Seeds are treated with scientific formula of seedsoaking liquid. Seedbeds are treated with multi-effect agent. The steps of treating rice seedlings with nutrient solution enable giant embryo rice seedlings to be sensitive to absorb zinc and iron from seeds. Therefore, seeds can absorb and accumulate zinc and iron from seedling stage, which is beneficial for the transfer and accumulation of zinc and iron in rice during the filling period. Giantembryo rice is adopted as zinc-rick and iron-rich cultivated species. According to the features of giant embryo rice, a set of cultivation method for zinc-rich and iron-rich giant-embryo rice is invented with special formulation medium, methods for germination and seedling as well as special ways to use zinc and iron fertilizer. As a result, the efficiency of accumulating zinc and iron in rice canbe greatly improved. Additionally, the content of zinc and iron in zinc-rich and iron-rich giant embryo rice is much higher than general zinc-rich and iron-rich rice.

Description

technical field [0001] The invention relates to a cultivation method of zinc-rich and iron giant embryo rice, belonging to the technical field of rice cultivation. Background technique [0002] Zinc is an essential trace element for the human body and is known as the "flower of life" and "the source of intelligence". Zinc plays an extremely important role in important physiological processes such as human growth and development, reproductive inheritance, immunity, endocrine, etc. It is necessary to supplement the human body. The trace element zinc has received widespread attention. Iron is also an essential trace element for the human body. Iron deficiency can cause iron-deficiency anemia. At present, iron-deficiency anemia is high in the population at home and abroad. Iron-deficiency anemia affects the overall quality of the people and is an urgent problem to be solved in the world. Adding zinc and iron nutritional fortifiers to food increases the amount of zinc and iron a...
