Abstract
It is reduced efficiently to apply the invention discloses a kind of nitrogenous fertilizer and plants rice method, including rice carries out plate rice breeding, wide-and narrow-row rice density plant, deep placement base manure placed in the middle in rice narrow row, the step such as strain side deep placement top dressing in rice wide row using the Nutrition Soil or matrix that mix and stir slow-release fertilizer.The present invention passes through Deep layer of rice field fertilising and rice strain rhizosphere fertilization, reduce fertilizer waves mistake loss and Loss in Runoff, have to utilize and improve utilization rate of fertilizer, in the case where keeping rice yield not subtract, subtract nitrogen fertilizer application up to more than 20%, nitrogenous fertilizer pollution of area source can be efficiently controlled, there are significant social economy's ecological benefits.
Description
Technical field
The present invention relates to a kind of nitrogenous fertilizer reducing application amount to plant rice method.
Background technology
Existing rice field nitrogen application process, utilization rate of fertilizer is low, and nitrogenous fertilizer pollution of area source is big, it is necessary to further be changed
Enter.
The content of the invention
It is an object of the invention to provide one kind to improve utilization rate of fertilizer, can efficiently control the nitrogenous fertilizer of nitrogenous fertilizer pollution of area source
Decrement, which is efficiently applied, plants rice method.
The present invention technical solution be：
A kind of nitrogenous fertilizer decrement, which is efficiently applied, plants rice method, it is characterized in that：Comprise the following steps：
（1）Rice carries out plate rice breeding using the Nutrition Soil or matrix for mixing and stirring slow-release fertilizer：Rice using plastics cave dish or
Hard disk seedling, more increase slow-release fertilizers in seedling raising ground substance or in Nutrition Soil, not cause rice shoot fertilizer damage as degree, and is mixed and stirred
It is even, select slow-release fertilizer species to be its fertilizer efficiency and apply speed in releasing for the 30 days nitrogen of being manured into soil and reach highest, applied before accomplishing seedling planting
With the purpose that fertilizer is had an effect by seedling strain rhizosphere behind transplanting crop field；The management requirement standard operation that seedbed is educated by drought；
（2）Wide-and narrow-row rice density is transplanted：Rice is planted using width line mode, and planting density increases than conventional during transplanting
20%；Using 30 centimetres of wide row line-spacing, 20 centimetres of narrow row line-spacing, conventional spacing in the rows；Or using 40 centimetres of wide row line-spacing, narrow row line-spacing
20 centimetres, spacing in the rows reduces 20% than conventional；
（3）Deep placement base manure placed in the middle in rice narrow row：During rice transplanting, middle position wire deep placement base manure, is applied in narrow row
Fertile depth is 5 ~ 6 centimetres, and the amount of nitrogenous fertilizer of administration is more conventional to reduce 20% ~ 30%；
（4）Strain side deep placement top dressing in rice wide row：Chase after and use tillering fertilizer and ear manuer.During top dressing 8 centimetres away from rice strain in wide row
Position, ribbon side dressing, 6 ~ 8 centimetres of fertilization depth, the more conventional reduction 20% ~ 25% of the amount of nitrogenous fertilizer of administration.
The present invention is applied fertilizer by Deep layer of rice field and rice strain rhizosphere fertilization, and reduce fertilizer waves mistake loss and Loss in Runoff,
Have using utilization rate of fertilizer is improved, in the case where keeping rice yield not subtract, subtract nitrogen fertilizer application up to more than 20%, can be effectively
Nitrogenous fertilizer pollution of area source is controlled, there are significant social economy's ecological benefits.
With reference to embodiment, the invention will be further described.
Embodiment
A kind of nitrogenous fertilizer decrement, which is efficiently applied, plants rice method, comprises the following steps：
（1）Rice is using the Nutrition Soil for mixing and stirring slow-release fertilizer（Or matrix）Carry out plate rice breeding.Rice uses plastics cave dish（Root
Cave band natives work transplanting）Or hard disk seedling（Root cave band soil transplanted by machine）, it is in seedling raising ground substance or in Nutrition Soil to increase more
Slow-release fertilizer（Specific data are not cause rice shoot fertilizer damage degree of being）, and uniform mixing, it is that its fertilizer efficiency is applying to select slow-release fertilizer species
The releasing of 30 days nitrogen of soil applies speed and reaches highest, is applied before accomplishing seedling planting, transplants fertilizer behind crop field and passes through seedling strain rhizosphere and sends out
The purpose of power.The management requirement standard operation that seedbed will be educated by drought, is educated by drought, not only cultivates the stalwartness that root amount is sufficient, seedling strain is short
Seedling, also can slow slow-release fertilizer fertility rate of release.（2）Wide-and narrow-row rice density is transplanted.Rice is planted using width line mode,
Planting density is than conventional increase by 20% during transplanting.Using 30 centimetres of wide row line-spacing, 20 centimetres of narrow row line-spacing, conventional spacing in the rows；Or use
40 centimetres of wide row line-spacing, 20 centimetres of narrow row line-spacing, spacing in the rows reduce 20% or so than conventional.By increasing density, to improve topsoil soil
Rice root starting point abundance in earth, subtract nitrogen fertilizer application increase yield to realize.（3）Deep placement base manure placed in the middle in rice narrow row.Rice
During transplanting, the middle position wire deep placement base manure in narrow row, 5 ~ 6 centimetres of fertilization depth is advisable, and the amount of nitrogenous fertilizer of administration is more conventional to be subtracted
Few 20% ~ 30%.（4）Strain side deep placement top dressing in rice wide row.According to the requirement of rice high yield high-quality management, optimum period chase after with tillering fertilizer and
Ear manuer（Fertilizer application period is the same as conventional）.Away from the cm position of rice strain 8, ribbon side dressing in wide row during top dressing.Fertilization depth 6
~ 8 centimetres, the more conventional reduction 20% ~ 25% of the amount of nitrogenous fertilizer of administration.
