Problems solved by technology

At the same time, the soil quality of farmland has deteriorated seriously, and production efficiency has dropped sharply
In addition, the long-term unreasonable use of farmland chemical fertilizers will also have a serious adverse impact on the water quality of lakes, surface water and groundwater resources, which is directly related to the water security of people in surrounding areas
At the same time, a large amount of NO3- accumulated in the soil can be converted into N2O through denitrification and released into the atmosphere, resulting in greenhouse effect

Embodiment 1

[0037] Embodiment 1 (wheat)

[0038] According to the technical regulations of wheat cultivation management, it is divided into two parts: base fertilizer and topdressing fertilizer. Among them, base fertilizer accounts for about 60% of the total fertilization amount, and topdressing fertilizer accounts for about 40%. Phase fertilizer, vegetative growth phase three fertilizer and reproductive growth phase fertilizer.

[0039] Three control groups CK were set up in the improvement experiment of wheat acidified soil 0 、CK 1 、CK 2 And treatment group T, each set up 3 repetitions;

[0040] CK 0 In order to operate completely in accordance with traditional fertilization methods, no reagents are added;

[0041] CK 1 Only in the base fertilizer stage, according to the nitrogen content of organic fertilizer (about 1.5%), add 1.0% NBPT;

[0042] CK 2In addition to adding 1.0% NBPT in the base fertilizer stage according to the nitrogen content of organic fertilizer (about 1.5%),...

Embodiment 2

[0054] Embodiment 2 (corn)

[0055] According to the technical regulations for corn cultivation management, corn fertilization is roughly divided into two parts: base fertilizer and topdressing. Among them, base fertilizer accounts for about 40-50% of the total fertilization, topdressing accounts for about 50-60%, and topdressing includes fertilizer at seedling stage and vegetative growth. Phase I fertilizer, fertilizer in the second phase of vegetative growth, fertilizer in the third phase of vegetative growth and fertilizer in the reproductive growth phase.

[0056] Three control groups CK were set up in the improvement experiment of maize acidified soil 0 、CK 1 、CK 2 and treatment group T, with 3 repetitions for each treatment;

[0057] CK 0 In order to operate completely in accordance with traditional fertilization methods, no reagents are added;

Embodiment 3

[0071] Embodiment 3 (rice)

[0072] According to the rice cultivation and management technical regulations, it is roughly divided into two parts: base fertilizer and topdressing fertilizer. Among them, base fertilizer accounts for about 60-80% of the total fertilization amount, and topdressing fertilizer accounts for about 20-40%. Fertilizer, vegetative growth phase II fertilizer, vegetative growth phase III fertilizer and reproductive growth phase fertilizer.

Abstract

The invention discloses an improvement method of acidified soil in a farmland. The improvement method comprises the steps of applying base fertilizer and applying additional fertilizer; when the basefertilizer is applied, N-butyl-thiophosphoryl triamide and aminoguanidine are respectively added according to the nitrogen content of organic fertilizer; when the additional fertilizer is applied, aminoguanidine and phenylhydrazine hydrochloride are respectively added according to the nitrogen content of applied nitrogen fertilizer. According to the overall improvement method, the defects that thetraditional improver is complex in operation, long in cycle and short in time of duration, the accumulation of heavy metals and the deterioration of physical and chemical properties of soil can be caused after long-time use of the traditional improver and so on are overcome; on the premises of ensuring the normal growth and yield of crops, the pH value of the acidified soil is efficiently and rapidly increased, and the quality of the soil is improved; in addition, the improvement method has the advantages of being simple and convenient to operate, stable in effect, long in time of duration and the like.

Description

technical field [0001] The invention relates to an improvement method, in particular to an improvement method for farmland acidified soil. Background technique [0002] Since the green industrial revolution in the 1960s, the world's total grain output has increased year by year. However, this substantial increase in grain output was obtained through intensive agricultural production based on the application of large amounts of nitrogen fertilizers. my country is a large agricultural country, and its grain output increased from 325 million tons in 1981 to 618 million tons in 2017, a growth rate of 90.2%, while the use of nitrogen fertilizers increased by 2-3 times, accounting for 35% of global nitrogen fertilizer consumption . [0003] The long-term excessive application of chemical fertilizers in farmland promotes the nitrification of the soil, and the NH in the soil 4 + Rapid conversion to NH under the catalysis of ammonium monooxygenase (AMO) 2 OH, which is then convert...
