Embodiment 1

[0031] In 2017, a demonstration base was established in Fushang Village Committee, Dabu Township, Yanshan District, Guilin City. The soil selenium content of the base reached 0.89 mg / kg, which belongs to selenium-rich soil. The demonstration area is 246 mu, and the planting variety is the conventional rice "Baishang 139".

[0032] The planting steps are as follows:

[0033] (1) Selection and arrangement of seedling fields: In Fushang Village, select seedling fields with flat terrain and fertile soil, apply 1000kg of decomposed farmyard manure per mu of seedling fields;

[0034] (2) Seed disinfection and germination treatment: A. Pre-soak in clean water for 12 hours, then remove and drain the water; B. Soak in 85% strong chlorine essence 400 times solution for another 12 hours, then wash and drain; C. Then use clean water After soaking for another 6 hours, drain and accelerate germination. When accelerating germination, pay attention to the temperature of 30°C±5°C and humidity ...

Embodiment 2

[0056] In 2018, a demonstration base was established in Jiangyan Village Committee, Baishou Town, Yongfu County, Guilin City. The soil selenium content of the base reached 0.65 mg / kg, which belongs to selenium-rich soil. The demonstration area is 214 mu. The planting varieties are conventional rice "Liuxiangzhan" and "Ivory Xiang Occupy" and so on.

[0057] The planting steps are as follows:

[0058] (1) Selection and arrangement of seedling fields: In Fushang Village, select seedling fields with flat terrain and fertile soil, and apply 1000kg of decomposed farmyard manure per mu of seedling fields;

[0059] (2) Seed disinfection and germination treatment: A. Pre-soak in clean water for 10 hours, pick up and drain the water; B. Soak in 85% strong chlorine essence 400 times solution for 12 hours, then wash and drain; C. Then use clean water After soaking for another 8 hours, drain and accelerate germination. When accelerating germination, pay attention to the temperature of 30...

Embodiment 3

[0082] In 2018, a demonstration base was established in Yanshan Village Committee, Huixian Town, Lingui District, Guilin City. The soil selenium content of the base reached 0.75mg / kg, which belongs to selenium-rich soil. The demonstration area is 189 mu. The planting varieties are conventional rice "Ivory Xiangzhan", "Meixiang accounted for" and so on.

[0083] The planting steps are as follows:

[0084] (1) Selection and arrangement of seedling fields: In Fushang Village, select seedling fields with flat terrain and fertile soil, and apply 1000kg of decomposed farmyard manure per mu of seedling fields;

[0085] (2) Seed disinfection and germination treatment: A. Pre-soak in clean water for 12 hours, pick up and drain the water; B.

Abstract

The invention belongs to the field of rice planting methods, and particularly provides a method for planting selenium-rich rice by plant-derived humic acid organic fertilizers. The method includes thesteps: (1) rice seedling bed selection and arrangement; (2) seed disinfection and germination treatment; (3) sowing; (4) rice seedling management; (5) field selection, land preparation and application of the plant-derived humic acid organic fertilizers serving as base fertilizers prepared by mixing, crushing and fermenting 40-50% of sugarcane filter mud, 10-20% of rice husks, 10-20% of corncobs,20-30% of livestock excrement and urine, 5-10% of humic acid and 5-10% of microbial agents; (6) rice transplanting; (7) field water and fertilizer management; (8) disease pest and weed comprehensive control; (9) harvesting. Organic selenium in soil is activated by the organic fertilizers comprising organic materials such as the humic acid and agricultural by-products, selenium is enriched by a physiological mechanism of rice, addition of exogenous selenium is omitted, the applying quantity of chemical fertilizers is decreased, pollution caused by pesticide residues is reduced, the yield and the quality of the rice can be improved, and sustainable development of agricultural production is facilitated.

Description

technical field [0001] The invention belongs to the field of rice planting methods, and specifically provides a method for planting selenium-enriched rice by utilizing plant-derived humic acid organic fertilizer. Background technique [0002] The content of selenium in human tissue is 1 / 10000000, but it determines the existence of life, and its great effect on human health is irreplaceable by other substances. In recent years, my country has set off an upsurge in the development of selenium-enriched industries. At present, the types of selenium-enriched products are increasing, especially agricultural products. Among agricultural products that are relatively mature in development and utilization are selenium-enriched tea, selenium-enriched rice, selenium-enriched eggs, selenium-enriched poultry meat, selenium-enriched edible fungi, and selenium-enriched vegetables and fruits (sweet potatoes, corn, bayberry, apples, etc.). [0003] Rice is an enduring product, and the popula...
