Technical Field

The invention relates to a rice fertilizer in a fertilizer preparation technology, in particular to a tillering fertilizer special for kinds of rice.

Background

The rice is which is the main food crop in China, has the characteristics of planting area, large area and the like, the yield accounts for more than 30% of the total yield of the food in China, although the sowing area of the rice is reduced year by year, the total yield of the rice is in the trend of increasing year by year with the introduction of new varieties, the quality of the rice production directly influences the food safety in China, the problems of poor tillering, lodging, serious pest and disease damage, unsatisfactory yield and the like are often encountered in the cultivation process of hybrid rice and super rice along with the large-area pushing of the hybrid rice and the super rice, the high-yield and high-quality production of the rice is also severely limited by the problems of series such as rice quality reduction, rice field ecological environment damage and the like, and the great part of the problems is considered to be caused by improper fertilization or fertilizer selection errors.

The prior art considers that the factors influencing the rice tillering are more and complex, but generally considers that the factors are related to the total nutrient quantity level absorbed by a rice root system and the contents of a nitrogen source, a cell auxin, a mitogen, naphthylacetic acid, abscisic acid and gibberellin, the total nutrient quantity level absorbed by the rice root system and the nitrogen source limit the upper limit of the rice tillering, the reasonable proportion of the cell auxin and the mitogen can promote the rice tillering, and the naphthylacetic acid, the abscisic acid and the gibberellin can inhibit the growth of the tillering bud, so that the hormone balance in the rice body is regulated and controlled in the tillering period, the key effect on the rice yield increase and quality improvement is not obvious, the related products related to the special tillering fertilizer for the rice in the market at present have the defects of low absorption efficiency, single function , single residue , the soil yield increase effect is not obvious, the rice yield increase effect is not easy to increase, and the rice plants are not easy to be degraded completely.

Disclosure of Invention

The technical problem to be solved by the invention is to provide special-purpose tillering fertilizers for rice, so as to solve the defects in the technical background.

The technical problem solved by the invention is realized by adopting the following technical scheme:

special rice tillering fertilizer comprises the following raw materials in parts by mass:

0.1-0.3 part of uniconazole

During preparation, the raw materials are weighed and sieved by a 100-mesh sieve, the raw materials are fully stirred and uniformly mixed, and the obtained mixture is added into a granulator for granulation to obtain the finished fertilizer.

As a further limitation of , the potash fertilizer is or any combination of potassium chloride, potassium sulfate, potassium nitrate, potassium feldspar powder, potassium magnesium salt, potassium humate and kiln dust potash fertilizer.

As a further limitation of , the supplemental nitrogen fertilizer is of ammonium bicarbonate, ammonium chloride, sodium nitrate, calcium nitrate, ammonium nitrate, or any combination thereof.

The phosphate mixture is defined in the step and is a mixture of ammonium dihydrogen phosphate and magnesium phosphate or potassium dihydrogen phosphate in a mass ratio of 3: 1-5: 1.

And , the tillering inducer is a compound mixture of at least three of cytokinin, polynucleic acid, potassium indolebutyrate and chitosan and S-abscisic acid in a mass ratio of 20: 1-30: 1.

As a further limitation of step , the raw materials can be optionally added with bentonite and/or trace element agent, the bentonite is optionally added in an amount of no more than 5% of the total mass of the raw materials, and the trace element agent comprises amino acid, zinc citrate, EDTA-Fe and EDTA-Zn.

The step is limited, when the special tillering fertilizer for rice is used, the special tillering fertilizer for rice is matched with a soil conditioner for use, the soil conditioner is a mixture of calcined potash feldspar and coal dust, zeolite, bentonite, vermiculite and organic carbon powder which are sieved by an 80-mesh sieve, and the mass ratio of the calcined potash feldspar is not less than 30%.

, the special tillering fertilizer for rice can be mixed with a compound fertilizer for granulation when the special tillering fertilizer for rice is granulated, wherein the mass fraction of total nutrients (nitrogen element + phosphorus trioxide + potassium oxide) in the compound fertilizer is more than or equal to 30%, the mass fraction of total nitrogen is more than or equal to 15%, the percentage of water-soluble phosphorus occupying effective phosphorus is more than or equal to 30%, the mass fraction of organic matters is more than or equal to 20%, and the pH value is 4.5-5.3, the special tillering fertilizer for rice is granulated after being mixed according to the mass ratio of the tillering fertilizer to the compound fertilizer of 1: 10-1: 30, and rice is directly fertilized in the tillering stage.

Has the advantages that: the special tillering fertilizer for rice has a scientific formula, is safe and comprehensive in function, provides a good carbon source and a good nitrogen source, can improve the activity of microorganisms, can improve the physicochemical property of rhizosphere soil, can stimulate a large amount of growth of fibrous roots of rice to provide dry matters for rice tillering, stimulates cell division and tissue differentiation by adding the tillering inducer, promotes rice tillering rooting, regulates and controls the capability of plants for balancing water absorption, nutrients and coordinating metabolism in vivo, promotes the absorption of the root system of rice to nutrient substances, increases the spike number and thousand kernel weight of rice, and further improves the quality and yield of rice.
