Abstract
The invention relates to agricultural chemistry, in particular to a fertilizer special for rice in black soil of cold regions and application of the fertilizer. The fertilizer special for the rice in black soil of the cold regions consists of a nitrogen fertilizer, a phosphate fertilizer, a potash fertilizer and zinc, wherein an active ingredient N of the nitrogen fertilizer accounts for 21 to 24 weight percent of the nitrogen fertilizer; an active ingredient P2O5 of the phosphate fertilizer accounts for 10 to 13 weight percent of the phosphate fertilizer; an active ingredient K2O of the potash fertilizer accounts for 12 to 14 weight percent of the potash fertilizer; and an active ingredient Zn accounts for 0.22 to 1.2 weight percent. The formula of the fertilizer special for the rice in black soil of the cold regions is provided according to a nutrient condition and a fertilizer supply law in black soil areas of the cold regions, and the fertilizer can obviously improve the yield and quality of the rice.
Description
Technical field
The present invention relates to agrochemistry, specifically a kind of cold ground black earth paddy rice-dedicated fertilizer and application thereof.
Background technology
Heilongjiang Province is the japonica rice plantation area of China's maximum, and existing rice area more than 4,350 ten thousand mu, wherein more than 40% is planted in black soil region.According to assay: produce 100 kilograms of paddy and straw, need nitrogen (N) 2.1-2.4 kilogram, phosphorus (P
2o
5) 0.9-1.3 kilogram, potassium (K
2o) 2.1-3.3 kilogram.Paddy rice is very strong to nitrogen reflection.Water paddy soil is due under flooding condition, aerobe growth is suppressed, nitrogen transformation in soil with organic matter becomes mineralising state slow or very difficult, and Nitrogen In Soils can run off with draining and infiltration water in addition, so the nitrogen that paddy growth needs must lean on fertilizer to supplement.The atteration major part of rice-cultivating is rich in phosphorus and potassium, and the phosphorus potassium running off from soil is also few than nitrogen.When phosphorus potassium is not enough, paddy growth is obstructed, maturation delays, disease resistance reduces.Take nitrogen as main, composite fertilizer's best results of the phosphorus potassium of arranging in pairs or groups in right amount.Like absorbing nitric nitrogen with most dry crops and compare, paddy rice likes absorbing ammonium nitrogen.I have carried out years of researches to paddy rice nitrogen, phosphorus, potassium nutrition and quality relation, according to black soil region nutrient situation and fertilizer rule, black soil region Fertilizer Prescription Special for Rice has been proposed, result of study shows, use this special fertilizer can obviously improve rice yield, improve quality, for black soil region, produce high-grade rice the foundation that applies fertilizers scientifically is provided.
Summary of the invention
The object of the invention is to provide a kind of cold ground black earth paddy rice-dedicated fertilizer and application thereof.
For achieving the above object, the technical solution used in the present invention is:
A cold ground black earth paddy rice-dedicated fertilizer, comprises, nitrogen, phosphorus, potassium and zinc are applicable to cold ground black earth paddy rice-dedicated fertilizer and are comprised of nitrogenous fertilizer, phosphate fertilizer, potash fertilizer and zinc, and the effective constituent of nitrogenous fertilizer, phosphate fertilizer, potash fertilizer and zinc is N:21%--24%, P by weight percentage
2o
5: 10%--13%, K
2o:12%--14%, Zn:0.22-1.2%.
Described paddy rice-dedicated fertilizer effective constituent, by weight nitrogen (N): phosphorus (P
2o
5): potassium (K
2o): zinc (Zn) is 1.9: 1: 1.2: 0.2.Described nitrogenous fertilizer is selected from urea, phosphate fertilizer and is selected from that monoammonium phosphate, potash fertilizer are selected from Repone K, zinc is selected from zinc sulfate.Described native paddy rice-dedicated fertilizer optimum proportion formula is: urea 397kg, monoammonium phosphate 250k, Repone K 217kg, zinc sulfate 136kg.
The application of cold ground black earth paddy rice-dedicated fertilizer: described paddy rice-dedicated fertilizer is applied to cold ground black earth, and rate of fertilizer application is at 20-25 kg/acre.
The present invention has advantages of:
Fertilizer provided by the present invention is to have proposed black soil region Fertilizer Prescription Special for Rice according to black soil region nutrient situation and fertilizer rule, adopts fertilizer of the present invention can obviously improve rice yield, improve quality.Field experiment proves, use paddy rice-dedicated fertilizer of the present invention, paddy rice growing way is good, tiller many, resistant to lodging, ripe morning, quality better, increasing both production and income, compare with conventional fertilizer, plant height improves 4.3cm, and grain number per spike increases by 9.8/fringe, and thousand seed weight increases 1.22g, from output, paddy rice-dedicated fertilizer is processed output per mu yield 650kg/ mu, than conventional fertile volume increase 45kg/ mu, the stimulation ratio 7.44% processed.In 2.85 yuan/kg of paddy rice, use paddy rice-dedicated fertilizer of the present invention, than conventional fertile processing, increase income 128.25 yuan/mu.
Embodiment
Embodiment 1
Paddy rice-dedicated fertilizer is urea 397kg, monoammonium phosphate 250kg, Repone K 217kg, zinc sulfate 136kg.By above-mentioned listed material and proportion relation thereof, take after raw material, mechanical stirring mixes granulation and obtains paddy rice-dedicated fertilizer.
Embodiment 2
Paddy rice-dedicated fertilizer is urea 400kg, monoammonium phosphate 250kg, Repone K 230kg, zinc sulfate 120kg.
Each composition in above-mentioned fertilizer is mixed to rear granulation, oven dry, screening according to corresponding ratio, and then metering packing, makes paddy rice-dedicated fertilizer material.Paddy rice-dedicated fertilizer should evenly spread fertilizer over the fields Tanaka by fertilizer before raking the soil level in soaked field, then fertilizer is harrowed into topsoil 6-8 centimetre or deeper and more, accomplishes deep fertilizer spraying, and fertilizer is executed in the reducing zone of rice terrace.Rice terrace is different from dry land, rice terrace under flooding condition minute zone of oxidation and reducing zone two-layer.The soaked rear upper soll layer of summer rice has the zone of oxidation of several centimetres and even 1-2 centimetre, is mainly here that aerobic bacteria carries out activity, below soil layer, be exactly reducing zone, be mainly that anaerobes carries out activity.During fertilizer surface fertilizing, in zone of oxidation, ammonium nitrogen carries out nitrification through microbiological oxidation and becomes nitrous state or nitric nitrogen, under be seeped into reducing zone, can not be run off by adsorption by soil; In addition, in the reducing zone of waterflooding, very easily produce denitrification, make nitrate-nitrogen reduction become molecular state nitrogen, or Nitrous Oxide, nitric oxide gas and scatter and disappear.Nitrogenous fertilizer deep placement, imposes on reducing zone fertilizer, to weaken the nitrogen loss of two processes of nitrification and denitrification, thereby improves utilization rate of fertilizer.While raking the soil level except sowing in spring, carry out deep fertilizer spraying, also can apply fertilizer in the autumn.Rate of fertilizer application is at 20-25 kg/acre.
