Description
Technical field
The present invention relates to agricultural technology field, particularly relate to a kind of promote Root Growth of Rice and turn green live put oxygen special fertilizer and preparation method thereof.
Background technology
The growth needs oxygen of rice root. When root system oxygen supply deficiency, Root Growth of Rice is suppressed, and new root is sprouted slow, and time serious, root system is dead. The bad function causing Root Absorption nutrient and moisture of root growth dies down, and the growth of corresponding Oryza sativa L. overground part is affected. When transplanting rice is owing to pulling up seedlings and transplanting, rice shoot root system is to damage, typically requires 5-7 days even longer time restoration ecosystem, root systems and could sprout the root that makes new advances, be commonly referred to as period of seedling establishment during this period of time after transplanting. Rice striking root is lived, and early low position tiller is many in a fast then tiller generation, thus being favorably improved the rice tillering percentage of earbearing tiller, and increases the effective fringe of Oryza sativa L. and yield; And alive of rice striking root is slow, tiller occurs late then effective tillering to reduce, rice yield reduction. In production, turning green a phase of living after rice transplanting, in order to prevent losing Seedling, after transplanting, generally to pour water and to set up the water layer of certain depth immediately; In tillering stage in order to prevent the loss of field fertilizer, field is generally also kept to be in the state of shallow water, until field Seedling number reaches number of targets and carries out draining dry field. And the oxygen needed for Root Growth of Rice comes from air, and after water layer is set up in rice field, the speed that air spreads to rhizosphere is severely impacted, the long waterflooding in rice field can cause that From The Rhizosphere of Rice oxygen supply is not enough, make Root Growth of Rice slack-off and Root Absorption function dies down, rice shoot period of seedling establishment after transplanting is elongated, and the tiller of Oryza sativa L. occurs late and the low change of rate of tillering panicle, finally affects rice yield. Magnesium is the moderate-element needed for paddy growth, and the effective content of magnesium in part rice field is relatively low, and when in rice field, the under-supply paddy growth of magnesium is suppressed, the underproduction is obvious, when the serious magnesium deficiency in rice field or dead at once causing rice seedling without magnesium elements.
Lack at present provide growth required for Oryza sativa L. simultaneously nitrogen, phosphorus, potassium, magnesium nutrient, and provide the fertilizer of oxygen needed for root growth the tillering stage of turning green after rice transplanting.
Summary of the invention
It is an object of the invention to solve the defect that above-mentioned prior art exists, there is provided a kind of and be possible not only to the disposable nitrogen required for Oryza sativa L. offer growth, phosphorus, potassium, magnesium nutrient, and root system oxygen supply can be increased, alleviate rice striking root tillering stage because the root system oxygen supply deficiency problem that causes of waterflooding, promote alive of rice striking root, promote rice tillering Cheng Sui, and finally increase yield put oxygen special fertilizer and preparation method thereof.
A kind of promote Root Growth of Rice and turn green live put oxygen special fertilizer, its raw material is by mass parts, including: carbamide 45-50 part, calcium superphosphate 20-23 part, potassium chloride 11-17 part, Magnesium dioxide 10-15 part, attapulgite 3-6 part, carboxymethyl cellulose 0.3-0.7 part, bitter pueraria root extract 1.0-1.5 part, Rhizoma Coptidis extract 0.5-1.0 part.
Further, promotion Root Growth of Rice as above puts oxygen special fertilizer with work of turning green, and described calcium superphosphate is phosphorus pentoxide effective content is the calcium superphosphate of 18%.
Further, promotion Root Growth of Rice as above puts oxygen special fertilizer with work of turning green, and described potassium chloride is potassium oxide effective content is the potassium chloride of 60%.
Further, promotion Root Growth of Rice as above puts oxygen special fertilizer with work of turning green, and described magnesium peroxide powder is industrial Magnesium dioxide, its effective ingredient 30%.
Further, promotion Root Growth of Rice as above puts oxygen special fertilizer with work of turning green, and described carboxymethyl cellulose is density is 0.5g/cm3, effective content be 95% industrial carboxymethyl cellulose.
Further, promotion Root Growth of Rice as above puts oxygen special fertilizer with work of turning green, described bitter pueraria root extract, carrying out extracting 3 times on 65 DEG C of shaking baths through absolute methanol for dry bitter Amylum Puerariae Radicis end, united extraction liquid, concentrating under reduced pressure reclaims methanol, transpiring moisture, spray drying obtains bitter pueraria root extract powder, and the size-reduced machine of powder is pulverized, and crosses the bitter pueraria root extract powder that 100 mesh sieves obtain.
The preparation method putting oxygen special fertilizer of a kind of promotion Root Growth of Rice described above and work of turning green, comprises the following steps:
1) pulverize after the carbamide of described weight portion, calcium superphosphate, potassium chloride and Magnesium dioxide being mixed, cross 100-160 mesh sieve, add the bitter pueraria root extract of described weight portion, Rhizoma Coptidis extract, stirring and evenly mixing, the composite granulated fertilizer that then technique causes diameter to be 3-4 millimeter routinely;
2) above-mentioned composite granulated fertilizer is put in rotary drum seed-coating machine, 30-40 DEG C preheats 5-10 minute, seed-coating machine rotating speed is 50-55 rev/min, preheat the attapulgite that backward rotary drum sprays into described weight portion and the carboxymethyl cellulose solution prepared by described carboxymethyl cellulose, control temperature after having sprayed and be 35-40 DEG C, discharging after 20-25 minute, air-dry, be namely promoted Root Growth of Rice and turn green live put oxygen special fertilizer.
Further, method as above, the concentration of described carboxymethyl cellulose solution by mass percentage, for 2%-5%.
Beneficial effects of the present invention:
1. the present invention by adding the Magnesium dioxide of appropriate amount in fertilizer, it is possible to the slow releasing oxygen in tillering stage of turning green after rice transplanting, promotes Root Growth of Rice, accelerate rice striking root tiller, thus promoting that low position tiller occurs, improving Oryza sativa L. number of productive ear, laying the first stone for rice high yield.
2. the present invention by adding the magnesium elements needed for paddy growth in fertilizer, can increase rice field magnesium elements supply, effectively reduces the under-supply adverse effect to Oryza sativa L. of rice field magnesium, promotes paddy growth.
3. the nitrogen in reasonable disposition fertilizer of the present invention, phosphorus, potassium ratio, the nutrient of fertilizer can meet Oryza sativa L. demand, contribute to play kind high yield potential; Fertilizer passes through attapulgite and carboxymethyl cellulose coating, reduces the rate of release of nutrient in fertilizer, reduces fertilizer loss; Fertilizer combination transplants the disposable deep placement in front whole field, contributes to the artificial input reducing in Rice Cropping.
4., by adding Chinese herbal medicine hardship Pueraria lobota and Rhizoma Coptidis extract in fertilizer in the present invention, it is possible to effectively suppress the generation of rice sheath blight disease and Pyricularia oryzae, thus reducing the use of chemical agent, while improving Rice Production safety, reduce the chemical agent pollution to environment.
5. the effect of increasing production that product of the present invention uses on Oryza sativa L. is obvious.
