Abstract
A kind of method that cadmium application drops in acidic soil conditioner on rice, belongs to soil conditioner field.Described soil conditioner includes cyanogen ammonia slag and regulus, and cyanogen ammonia slag and regulus proportioning are respectively 40：60 or 50:50.Every mu of rice terrace is 70 80 Kg from soil conditioner, is uniformly spread fertilizer over the fields within 5 days in transplanting rice before seedling, and every mu of late July imposes the Kg of urea 11, treats rice maturity in October, investigation drop cadmium situation.This method can effectively reduce the content of beary metal such as cadmium ion, reach increasing crop yield, improve agricultural product quality, and safely, green.
Description
Technical field
The invention belongs to soil conditioner technical field, cadmium drops in more particularly to a kind of acidic soil conditioner on rice should
Method.
Background technology
Rice is one of China and the most important crops of world's most area, as China the first generalized grain crop,
There is larger cultivated area in the whole nation, played a significant role in China's grain security.Rice because its plant it is with a long history and
Cultivation it is intensive etc., fertilising and miscarriage turn into an important factor for influenceing Rice Production.The wherein weight such as soil cadmium ion
Tenor height is one of factor for influenceing paddy soil and rice yield.At present, paddy field application by throwing them is Common compound fertilizer, right
It is very undesirable that cadmium effect drops.
The content of the invention
The purpose of the present invention is that the content of beary metal height such as cadmium ion is good for human body in soil and rice for existing rice
The weak point of Kang Buli situation, there is provided a kind of application of acidic soil conditioner on rice reduces the technical side of cadmium ion
Case.
A kind of method that cadmium application drops in acidic soil conditioner on rice, described acidic soil conditioner include cyanogen ammonia
Slag and metal magnesium slag, cyanogen ammonia slag and metal magnesium slag proportioning are respectively 40：60 or 50:50.
The species and scope of described cyanogen ammonia slag, including but not limited to dicyandiamide, single cyanogen ammonia, thiocarbamide, carbendazim and cyanogen ammonia
Change all solids thing after calcium hydrolysis solid and liquid separation.
The composition of described cyanogen ammonia slag includes calcium carbonate, organic carbon, silica, alundum (Al2O3) and di-iron trioxide,
The ratio of above-mentioned constituent each component is：Calcium carbonate 80-85%, organic carbon 9-10%, silica 2-3.5%, alundum (Al2O3) 1-
1.5%, di-iron trioxide 0.6-0.9%, micro- magnesia, calcium hydroxide, chlorine, sodium are no more than 1%, and the pH value of cyanogen ammonia slag exists
Between 9-10.
The composition of described metal magnesium slag includes calcium oxide, silica, magnesia, alundum (Al2O3) and three oxidations two
Iron, the ratio of above-mentioned constituent each component are：Calcium oxide 53-56%, silica 29-31%, magnesia 7-8%, di-iron trioxide
5-6.5%, alundum (Al2O3) 1-2.5%, trace element, potassium, chlorine, sodium, boron, molybdenum are no more than 1%, and the pH value of metal magnesium slag is in 11-12
Between.
A kind of method that cadmium application drops in acidic soil conditioner on rice.Soil conditioner is applied in rice terrace for every mu
70-80 Kg。
Application process：Uniformly spread fertilizer over the fields within 5 days in transplanting rice before seedling, every mu of late July imposes the Kg of urea 11, treats 10
Month rice maturity, investigation rice is to the uptake situation of cadmium ion.
Cadmium ion in the later paddy soil of mugineic acid soil conditioner and harvest rice is respectively than without using acidity
The total cadmium content rate of descent of paddy soil and rice of soil conditioner is between 55-75%.
The present invention has following remarkable result：
1st, the present invention in soil conditioner contain cyanogen ammonia slag, metal magnesium slag can be used as soil conditioner and in micro member
Fertilizer, the middle trace quantity mineral substance element needed for improved soil, supplement plant growth, improves the pH value of acid soil, improves it
The utilization rate of its fertilizer.
2nd, product of the present invention and method can effectively reduce cadmium pollution in rice terrace and rice, improve agricultural product quality and
Effect of increasing production, and safely, green.
Embodiment
The embodiment of the present invention is with reference to embodiment.
Every mu of rice terrace of the embodiment of the present invention is 75Kg and 80Kg from soil conditioner, common with general paddy field application by throwing them
Composite fertilizer contrasts.
Embodiment 1：
Test site is in hengyang, hunan province Liao Tian Town rice terrace, from excellent No. 59 kinds of late rice gold, in transplanting rice before seedling 5
My god, mid-July per it is per mu it is even spread fertilizer over the fields 75Kg soil conditioners, every mu of late July, which imposes, builds the Kg of peak urea 11, treats water in October
The rice maturity period, investigation drop cadmium situation, the later paddy soil of rice application acidic soil conditioner and harvest rice in cadmium from
Son is respectively than the paddy soil without using acidic soil conditioner and the total cadmium content rate of descent of rice 60%.P in soil H values by
5.02 bring up to 6.27, and every mu of increasing production of rice 16.19%, every mu increases income 112 yuan.
Embodiment 2：
Test site is in hengyang, hunan province Liao Tian Town rice terrace, from excellent No. 59 kinds of late rice gold, in transplanting rice before seedling 5
My god, mid-July per it is per mu it is even spread fertilizer over the fields 85Kg soil conditioners, every mu of late July, which imposes, builds the Kg of peak urea 11, treats water in October
The rice maturity period, investigation drop cadmium situation, the later paddy soil of rice application acidic soil conditioner and harvest rice in cadmium from
Son respectively than the paddy soil without using acidic soil conditioner and the total cadmium content rate of descent of rice 72%, P in soil H values by
5.02 bring up to 6.29, and every mu of increasing production of rice 18.50%, every mu increases income 132 yuan.
Ningxia Daiei Chemical Co., Ltd. be it is domestic first cyanogen ammonolysis product is registered as agricultural chemicals and plant growth regulation
Enterprise, according to experiment, the demonstration in agriculture application field for many years, it was found that cyanogen ammonia is in soil improvement and Effects on Plant Growth, work(
