Description
Technical field
The present invention relates to agricultural technology field of planting, and in particular to a kind of fertilization of rice method suitable for salt-soda soil.
Background technique
Saline alkali land area is wide in world wide, according to UNESCO and food and agricultural organization's incomplete statistics, entirely
The area in world salt-soda soil is 9.5 hundred million hectares, and wherein China is 0.99 ten thousand hectares, close to 100,000,000 hectares, that is, 1,500,000,000 mu.Its
In, 2.8 hundred million mu of salt-soda soils are to be badly in need of transformation, and in this 2.8 hundred million mu of salinization lands, have 1.4 hundred million mu to plough at 1,800,000,000 mu
Within red line, remaining 1.4 hundred million mu are Unutilized Energies that Ministry of Land and Resources defines.
With the increase of urban size, cultivated area is constantly reduced, while the size of population is continuously increased, and the mankind are also facing
The severe challenge of grain.
Rice is the staple food crop in China, and there is nearly 2/3 population in the whole nation using rice as staple food.Rice cropping area accounts for
The 1/3 of foodstuff planting area, but yield accounts for about the 40% of total output of grain.And salt-soda soil, since natural conditions are severe, salinity contains
Amount is high, and it is less to can adapt to the crop grown in salt-soda soil.
Therefore Rice Production is extremely important in guarantee China's grain security supply respect.Existing research table
Bright, salt alkaline tolerance rice has certain salt tolerant alkali ability, can be effectively reduced soil salinity and alkalinity, reaches the effect in improvement salt-soda soil
Fruit.Alkaline land soil fertility is poor, and the content of organic matter is low, and soil aggregate structure is poor, and usual people can be improved by blindness fertilising
Soil fertility increases rice yield.
Base fertilizer is a most basic link in fertilising, extremely to crop growth especially seedling stage and plant growth early period
Close it is important, application base fertilizer generally will be from the aspect of four: i.e. the depth of the type, quantity of base fertilizer, fertilizer variety and application.
Base fertilizer is a most basic link in fertilising, extremely to crop growth especially seedling stage and plant growth early period
Close important, base fertilizer fertilizer practice generally will be from the aspect of four: i.e. the depth of the type, quantity of base fertilizer, fertilizer variety and application
Degree.
From type, organic fertilizer (including farmyard manure, barnyard manure, green manure and cake fertilizer) optimum makees base fertilizer application, furthermore nitrogen,
Phosphorus, potassium and micro- fertilizer are also all suitable for base fertilizer.Determine base fertilizer application quantity especially applying quantity of chemical fertilizer, it is necessary to consider soil fertility
Just, the organic fertilizer of 3 cubic metres/mu or more should be applied in soil of the organic matter lower than 1.2%.
When available nitrogen, phosphorus, potassium and microelement are lower than the effective critical value of crop fertilization in soil, bottom should be just selected first
It applies these fertilizer, especially crop and needs more phosphate fertilizer in early period.The specific dosage that various fertilizer make base fertilizer can refer to locality
The composite factors such as many years of field manure trial result and target output are determining, the 30% of the total dosage of nitrogenous fertilizer on general high fertility soil
Left and right bottom application, in, low fertility soil then have 50%~70% nitrogenous fertilizer as base fertilizer, and phosphorus, potash fertilizer and micro- fertilizer are as primary as possible
Whole bottom application.From fertilizer variety, ammonium bicarbonate in nitrogenous fertilizer, general calcium, diammonium, calcium magnesium phosphate, three material in phosphate fertilizer, chlorine in potash fertilizer
Change potassium, potassium sulfate, plant ash, zinc fertilizer, manganese fertilizer etc. in micro- fertilizer, are all suitable for making base fertilizer.
It is said in terms of depth, general base fertilizer should be applied within entire topsoil, i.e., 15~20 centimetres of depth.For organic
Fertilizer, nitrogenous fertilizer, potash fertilizer, micro- fertilizer, are equably sprinkling upon earth's surface, plough bury immediately after can mixing, accomplish fertilizer and full topsoil soils
Uniformly mixing, so that nutrient is absorbed and utilized in crop difference root zone.Phosphate fertilizer is due to poor mobility, and after being manured into soil easily
It is fixed and loses validity, therefore applied in bottom application Shi Yingfen upper layer and lower layer, i.e., lower layer applies to 15~20 centimetres of depth, upper layer
It applies to 5 centimetres or so of depth.Upper layer mainly meets the needs of crops seedling stage is to phosphorus, and lower layer supplies the plant growth intermediary and later stages
Phosphorus nourishing.
The fertilizer for making base manure application is the fertilizer of late effect property mostly.Barnyard manure, compost, family's animal manure etc. are most common base manure.
The phosphate fertilizer and potash fertilizer of chemical fertilizer generally also make base manure application.The nitrogenous fertilizer of chemical fertilizer, such as ammonium hydroxide, liquefied ammonia and ammonium hydrogen carbonate, precipitating
The chemical fertilizer such as calcium phosphate, calcium magnesium phosphate, ground phosphate rock are suitable to make base manure.Join chemical industry raw medicine: diethyl aminoethyl hexanoate in fertilizer additive generally use
(DA-6), compound sodium nitrophenolate, chloropyuril (KT-30), Nafusaku etc.；The ingredient of base manure: generally there are turf, perlite, vermiculite.
Rice cultivation fertilising is the key that Rice Cropping in salt-soda soil, and the application of base fertilizer is even more the weight of entire fertilising process
In weight therefore study the base fertilizer method of administration of suitable salt-soda soil rice cultivation a kind of to realizing that the rice rational application of fertilizer especially must
It wants.
Summary of the invention

In being first continuously increased the trend then reduced, and behave oneself best at 10000kg/ mus of dose, yield reaches 324.3kg/ mus.
The yield of rice in the case of 1 Different Fertilization of table
As a result two are measured:
By the measurement of Plant Height of Rice it can be seen that being continuously increased with base fertilizer amount of application, Plant Height of Rice is in first continuous
Increase the trend then reduced, and behave oneself best at 10000kg/ mus of dose, plant height reaches 98.5cm.
The plant height of rice in the case of 2 Different Fertilization of table
By the long measurement of Flag Leaves in Rice it can be seen that being continuously increased with base fertilizer amount of application, Flag Leaves in Rice are long in first
It is continuously increased the trend then reduced, and is behaved oneself best at 10000kg/ mus of dose, 22.5cm is reached.
The sword-like leave of rice is long in the case of 3 Different Fertilization of table
In conclusion by the way that yield to rice, plant height, sword-like leave be long etc., indexs are measured, and find it in 10000kg/
Behave oneself best when mu, therefore, 10000kg/ mus of organic fertilizer base fertilizer amount of application is best.
