Embodiment 1

[0017] First produce selenium-enriched liquid fertilizer according to the following steps:

[0018] (1) According to the weight ratio, add 1 part of pig, sheep, cattle and other stable manure to 10 parts of water, and after natural storage for 8 months, filter it through 200 mesh to obtain the filtrate.

[0019] (2), by weight, with 1 part of sodium selenite, add 50 parts of filtrate, stir evenly, carry out natural biological fermentation at a temperature of 21° C. for 25 days to obtain selenium-enriched liquid fertilizer.

[0020] The production method of using this selenium-enriched liquid fertilizer for selenium-enriched agricultural products is to dilute 1 part of selenium-enriched liquid fertilizer with 500 parts of water (by weight), and spray it on the plants after 15:00 when there is no wind before the agricultural products are harvested. Behind the leaves, and does not form water droplets on the ground.

Embodiment 2

[0022] First produce selenium-enriched liquid fertilizer according to the following steps:

[0023] (1) According to the weight ratio, add 1 part of pig, sheep, cattle and other stable manure to 8 parts of water, and after natural storage for 6 months, filter it through 100 mesh to obtain the filtrate.

[0024] (2), by weight, with 1 part of sodium selenite, add 50 parts of filtrate, stir evenly, carry out natural biological fermentation at a temperature of 28°C for 20 days to obtain selenium-enriched liquid fertilizer.

[0025] This selenium-enriched liquid fertilizer is used for the pollution-free production method of selenium-enriched tea, after 1 part of selenium-enriched liquid fertilizer is diluted with 400 parts of water (by weight), spray 50kg on the tea tree per mu, and focus on the back of the blade, and do not Form water droplets on the ground. They were sprayed 7 days, 14 days, 21 days, and 28 days before tea mining. The selenium content in tea is shown in Table ...

Embodiment 3

[0027] First produce selenium-enriched liquid fertilizer according to the following steps:

[0028] (1) According to the weight ratio, 1 part of manure such as pigs, sheep and cattle, and 14 parts of water are added, and after natural storage for 8 months, it is filtered through 300 mesh to obtain the filtrate.

[0029] (2), by weight, add 1 part of sodium selenite and 50 parts of filtrate, stir well, and carry out natural biological fermentation at a temperature of 25°C for 30 days to obtain selenium-enriched liquid fertilizer.

[0030] This selenium-enriched liquid fertilizer is used in the pollution-free production method of selenium-enriched pears, after 1 part of selenium-enriched liquid fertilizer is diluted with 500 parts of water (by weight), spray 60kg per mu on the pear tree, focus on the back of the blade, and Does not form water droplets on the ground. They were sprayed 7 days, 14 days, 21 days, and 28 days before the crystal pears were picked. See Table 2 for th...

Abstract

A Se-enriched liquid fertilizer is prepared from barnyard manure through proportionally mixing it with water, natural stacking for at least 6 months, filtering, proportionally mixing the filtrate with sodium selenite, and natural fermenting for 15-35days. It can be used to culture Se-enriched agricultural crops and obtain the Se-enriched agricultural products by diluting it with water and spraying it on the plants of agricultural crops.

Description

technical field [0001] The invention relates to a fertilizer for producing selenium-enriched agricultural products, in particular to a fertilizer for producing selenium-enriched tea and selenium-enriched fruits (such as pears, grapes, strawberries, peaches, green plums, and plums), and at the same time relates to the use of the fertilizer in the production of selenium-enriched agricultural products method. Background technique [0002] At present, there are two main methods of supplementing selenium for the production of selenium-enriched agricultural products. One is to directly spray inorganic selenium such as sodium selenite on the leaves of plants or apply it in the soil; the other is to apply organic selenium fertilizer in the soil apply. The former is not only low in the availability of selenium and economically poor due to a large amount of drifting away, soil fixation, etc., but also causes environmental pollution due to excessive seleni...
