Abstract
The invention discloses a rice planting method for efficiently applying nitrogenous fertilizer in a quantity reducing mode. The rice planting method comprises the steps that nutrient soil or substrates mixed with slow release fertilizer are adopted to carry out plate rice seedling raising on rice; the rice is planted in wide rows and narrow rows in a densification mode; base fertilizer is deeply applied in the middles of the narrow rows of the rice; deep application and topdressing are carried out beside plants in the wide rows of the rice. The volatilization loss and runoff loss of the fertilizer are reduced through rice field deep fertilizer application and rice plant rhizosphere fertilizer application, the utilization rate of the fertilizer can be improved, under the conditions of keeping the yield of the rice not to be reduced, the applied nitrogenous fertilizer can be reduced by over 20 percent, the non-point source pollution of the nitrogenous fertilizer can be effectively controlled, and remarkable social, economic and ecological benefits are achieved.
Description
Technical field
The present invention relates to a kind of nitrogenous fertilizer reducing application amount and 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 large, needs to be improved further.
Summary of the invention
The object of the present invention is to provide and a kind of improve utilization rate of fertilizer, the nitrogenous fertilizer decrement that effectively can control nitrogenous fertilizer pollution of area source is efficiently used and is planted rice method.
Technical solution of the present invention is:
A kind of nitrogenous fertilizer decrement is efficiently used and is planted rice method, it is characterized in that: comprise the following steps:
(1) paddy rice adopts and mixes and stirs the Nutrition Soil of slow-release fertilizer or matrix carries out plate rice breeding: paddy rice adopts plastics cave dish or hard disk seedling, in seedling raising ground substance or in Nutrition Soil, increase slow-release fertilizer more, not cause rice shoot fertilizer damage for degree, and uniform mixing, select slow-release fertilizer kind to be its fertilizer efficiency releasing of the 30 days nitrogen that is manured into soil to execute speed and reach the highest, use before accomplishing seedling planting, the object that after transplanting land for growing field crops, fertilizer is had an effect by seedling strain rhizosphere; The management expectancy standard operation that seedbed is educated by drought;
(2) wide-and narrow-row rice density is planted: paddy rice adopts wide-and narrow-row mode to plant, and during transplanting, planting density increases by 20% than conventional; Adopt wide every trade apart from 30 centimetres, narrow row line-spacing 20 centimetres, conventional spacing in the rows; Or adopting wide every trade apart from 40 centimetres, narrow row line-spacing 20 centimetres, spacing in the rows reduces 20% than routine;
(3) deep placement base manure placed in the middle in paddy rice narrow row: during rice transplanting, middle position wire deep placement base manure in narrow row, fertilization depth is 5 ~ 6 centimetres, the more conventional minimizing 20% ~ 30% of the amount of nitrogenous fertilizer used;
(4) in the wide row of paddy rice, strain side deep placement topdresses: chase after with tillering fertilizer and ear manuer.Apart from rice strain 8 centimetres of positions in the Shi Kuan that topdresses is capable, ribbon side dressing, fertilization depth 6 ~ 8 centimetres, the minimizing 20% ~ 25% that the amount of nitrogenous fertilizer used is more conventional.
The present invention is by Deep layer of rice field fertilising and rice strain rhizosphere fertilization, decrease waving of fertilizer and lose loss and Loss in Runoff, have to utilize and improve utilization rate of fertilizer, when keeping rice yield not subtract, subtract nitrogen fertilizer application and can reach more than 20%, can effectively control nitrogenous fertilizer pollution of area source, there are significant social economy ecological benefits.
Below in conjunction with embodiment, the invention will be further described.
Embodiment
A kind of nitrogenous fertilizer decrement is efficiently used and is planted rice method, comprises the following steps:
(1) paddy rice adopts the Nutrition Soil (or matrix) mixing and stirring slow-release fertilizer to carry out plate rice breeding.Paddy rice adopts plastics cave dish (transplanting of root cave band natives work) or hard disk seedling (root cave band soil transplanted by machine), increase slow-release fertilizer (concrete data are not for causing rice shoot fertilizer damage for degree) in seedling raising ground substance or in Nutrition Soil more, and uniform mixing, select slow-release fertilizer kind to be its fertilizer efficiency releasing of the 30 days nitrogen that is manured into soil to execute speed and reach the highest, use before accomplishing seedling planting, the object that after transplanting land for growing field crops, fertilizer is had an effect by seedling strain rhizosphere.The management expectancy standard operation that seedbed will be educated by drought, is educated by drought, not only cultivates the healthy and strong seedling that root amount foot, seedling strain are short, also can the fertility rate of release of slow slow-release fertilizer.(2) wide-and narrow-row rice density is planted.Paddy rice adopts wide-and narrow-row mode to plant, and during transplanting, planting density increases by 20% than conventional.Adopt wide every trade apart from 30 centimetres, narrow row line-spacing 20 centimetres, conventional spacing in the rows; Or adopting wide every trade apart from 40 centimetres, narrow row line-spacing 20 centimetres, spacing in the rows reduces about 20% than routine.By increasing density, to improve rice root starting point abundance in topsoil soils, to realize subtracting nitrogen fertilizer application increase yield.(3) deep placement base manure placed in the middle in paddy rice narrow row.During rice transplanting, middle position wire deep placement base manure in narrow row, fertilization depth 5 ~ 6 centimetres is advisable, the more conventional minimizing 20% ~ 30% of the amount of nitrogenous fertilizer used.(4) in the wide row of paddy rice, strain side deep placement topdresses.According to the requirement of rice high yield high-quality management, optimum period, chases after with tillering fertilizer and ear manuer (fertilizer application period is with conventional).Apart from rice strain 8 cm position in the Shi Kuan that topdresses is capable, ribbon side dressing.Fertilization depth 6 ~ 8 centimetres, the minimizing 20% ~ 25% that the amount of nitrogenous fertilizer used is more conventional.
