Problems solved by technology

In recent years, with the large-scale promotion of hybrid rice and super rice, problems such as lodging, serious pests and diseases, and yield not reaching the ideal level are often encountered during rice cultivation, and the emergence of these problems also seriously limits the high-yield and high-quality rice. chemical production
[0003] During the growth and development of rice, although the demand for micronutrient elements is very small, any lack or high content of any trace element in the soil will affect the growth and development of rice, resulting in a serious decline in yield and quality, and Further affect human health through the food chain

Embodiment 1

[0021] Weigh 30g of borax, 10g of ammonium molybdate, 10g of sodium molybdate, 5g of zinc sulfate heptahydrate, 15g of chelated zinc, and 3g of sodium selenite, pour them into 75g of water, then put the solution into a magnetic stirrer, set the speed After stirring at 800rpm for 3 minutes, add 2g of compound amino acid, 0.5g of synergist and 2g of emulsifier, set the rotation speed at 1200rpm and stir for 30 minutes to obtain boron-zinc-molybdenum fertilizer specially used for rice. The fertilizer is mixed with 200 times of water, and sprayed once every 7 days in the initial stage of rice growth, and the amount of spraying per mu of paddy field is 50ml.

[0022] The compound amino acid is composed of cystine, leucine, methionine, arginine, serine, tyrosine, threonine, lysine, isoleucine and histidine.

Embodiment 2

[0024] Take by weighing 37g of borax, 12g of ammonium molybdate, 12g of sodium molybdate, 6g of zinc sulfate heptahydrate, 18g of chelated zinc, and 3.5g of sodium selenite, pour them into 100g of water, then put the solution into a magnetic stirrer, set After stirring at 900rpm for 4 minutes, add 3g of compound amino acid, 0.8g of synergist and 3g of emulsifier, set the rotating speed at 1280rpm and stir for 35 minutes to obtain boron-zinc-molybdenum fertilizer for rice. The fertilizer is mixed with 250 times of water, and sprayed once every 10 days in the initial stage of rice growth, and the amount of spraying per mu of paddy field is 100ml.

[0025] The compound amino acid is composed of cystine, leucine, methionine, arginine, serine, tyrosine, threonine, lysine, isoleucine and histidine.

Embodiment 3

[0027] Weigh 42g of borax, 14g of ammonium molybdate, 12g of sodium molybdate, 7g of zinc sulfate heptahydrate, 21g of chelated zinc, and 4g of sodium selenite, pour them into 180g of water, then put the solution into a magnetic stirrer, set the speed After stirring at 1000rpm for 5 minutes, add 3.5g of compound amino acid, 1.5g of synergist and 4g of emulsifier, set the rotation speed at 1350rpm and stir for 40 minutes to obtain boron-zinc-molybdenum fertilizer specially used for rice. Mix the fertilizer with 300 times of water, spray once every 14 days in the initial stage of rice growth, and the spray amount per mu of paddy field is 200ml.

[0028] The compound amino acid is composed of cystine, leucine, methionine, arginine, serine, tyrosine, threonine, lysine, isoleucine and histidine.

Abstract

The invention discloses a boron-zinc-molybdenum fertilizer special for rice. The fertilizer is prepared from borax, ammonium molybdate, sodium molybdate, zinc sulfate heptahydrate, chelated zinc, sodium selenite, compound amino acid, a synergist and an emulsifying agent. According to the boron-zinc-molybdenum fertilizer, nutrients can be balanced, the water retention capability and the fertilizer retention capability can be improved, growing and early maturing of the rice can be promoted, the quality of the rice can be improved, and the yield of the rice can be increased; by spraying the fertilizer, the zinc content in the rice can be increased, and the health care functions of the rice are improved; in addition, the soil structure can be adjusted, pest and disease damage can be prevented and controlled, the utilization rate of the fertilizer can be increased, and the very good economic benefit and social benefit are achieved.

Description

technical field [0001] The invention relates to the field of pesticides and chemical fertilizers, in particular to a special boron, zinc and molybdenum fertilizer for rice and a preparation method thereof. Background technique [0002] Rice is an important commodity grain in my country. It has the characteristics of wide planting area and large area. In addition to self-sufficiency, some of it can be exported every year, which is of great significance to my country's food security. Therefore, rice production has always been a hot field of research. In recent years, with the large-scale promotion of hybrid rice and super rice, problems such as lodging, serious pests and diseases, and yield not reaching the ideal level are often encountered during rice cultivation, and the emergence of these problems also seriously limits the high-yield and high-quality rice. chemical production. [0003] During the growth and development of rice, although the demand for micronutrient element...
