Description
Technical field
The present invention relates to a kind of paddy rice-dedicated fertilizer with slow release effect, belong to Crop fertilizer technical field.
Background technology
Rice is the second-biggest-in-the-world cereal crops for being only second to wheat.China's sown area accounts for cereal crops sown area
30% or so, and rice yield accounts for more than the 40% of total grain output, sown area and total output occupy cereal crops first place.The whole nation
More than 60% population is that the important leverage of the population of the world 22% is supported in the arable land in the world of China 7% using rice as staple food.
Rice normal growth and development needs more nutrient, especially big to the requirement of three kinds of nitrogen, phosphorus, potassium elements,
Supplied by soil merely, it is impossible to meet the needs of rice growth, it is therefore desirable to apply fertilizer.Nitrogenous fertilizer is rice growth mistake
The first big nutrient required in journey, play an important roll to improving crop yield, but apply excessively, can run counter to desire；
It is excessive in rice growing season nitrogen fertilizer application, rice plant nutrient growth can be caused luxuriant, plant increases softening, causes under rice early stage
Portion covers, and humidity and the relative raising of temperature, draws badly, gives pest and disease damage to provide condition；It is a large amount of in rice body and nitrogenous fertilizer is excessive
Accumulation nitrate nitrogen causes poisoning, and lower blade withered morning, root is easy to aging, and the cane of ineffective tillering will lodge, and bring and seriously subtract
Production, therefore the used in amounts of nitrogenous fertilizer strictly controls.Chemical fertilizer is applied frequently with mode multiple by several times at present, to ensure rice abundance
Nutrient supply, but it is time-consuming laborious, and cost input is more, with nitrogen, phosphorus, the increase of potassium amount of application, macronutrient phase
To enrichment, not only cause utilization rate to decline, and waste resource, pollute environment, as macronutrient is superfluous, soil
Middle micronutrient levels has been unable to meet demand, and rice trace element deficiency is also increasing, though develop a variety of has at present
Machine fertilizer, but its nutrient is volatile, is lost in, and fertilizer efficiency is fast, not persistently, and is relatively also easy to produce pest and disease damage.
The content of the invention
It is an object of the invention to solve the deficiency of paddy rice-dedicated fertilizer in the prior art, there is provided a kind of with slow release effect
Paddy rice-dedicated fertilizer, its nutrient is balanced, utilization rate of fertilizer is high, can effectively avoid paddy growth nitrogenous fertilizer early stage surplus, mid-term nitrogenous fertilizer fertilizer
Effect deficiency can strengthen paddy disease-resistant insect pest ability to adverse effect caused by paddy growth, improve the yield and product of rice
Matter.
Technical scheme
A kind of paddy rice-dedicated fertilizer with slow release effect, is made up of the raw material of following parts by weight：33~35 parts of oxamides, 15
~16 parts of urea, 22~25 parts of phosphate fertilizer, 23~25 parts of potash fertilizer, 1~2 part of zinc fertilizer, 1~2 part of siliceous fertilizer.
Further, the phosphate fertilizer is the mixture of MAP, Diammonium phosphate (DAP) or the two arbitrary proportion.
Further, the potash fertilizer is potassium chloride.
Further, the zinc fertilizer is zinc sulfate.
Further, the siliceous fertilizer is nano active silicon.
The nitrogenous fertilizer of the present invention is mixed by slow-release nitrogen fertilizer with common azophoska by special proportioning, and the paddy rice-dedicated fertilizer is total
Nutrient content is 44%~47%, and wherein nitrogen N effective content is 20%~21%, phosphorus P2O5Effective content for 10%~
11%th, potassium K2O effective content is 14%~15%, and the pure nitrogen level of wherein oxamides accounts for the 55%~60% of nitrogen pool.
The preparation method of the above-mentioned paddy rice-dedicated fertilizer with slow release effect：By oxamides, urea, phosphate fertilizer, potash fertilizer, zinc fertilizer and
After siliceous fertilizer crushes, it is uniformly mixed, then through being granulated, and dried at a temperature of 60-80 DEG C, produce paddy rice-dedicated fertilizer.
The paddy rice-dedicated fertilizer that the present invention has slow release effect is applied as base manure, and every mu of amount of application is 40~50kg.
The advantage of the invention is that：(1) apply simply, applied as base manure, and rice top dressing number can be reduced, saving of labor saves
When；(2) Fertilizer nutrient is balanced, and fertilizer amount and rice demand are basically identical, it is ensured that the supply of rice prometaphase nutrient, coordinates
Middle trace element, is more beneficial for paddy growth needed for rice；(3) rice is typically to like ammonium crop, the ammonium nitrogen in special fertilizer
Fertilizer is more beneficial for the growth of rice；(4) oxamides in special fertilizer has good sustained release performance, both may insure rice early stage
To the demand of nitrogen, and can ensures the lasting supply of rice middle and later periods nitrogen.Compared with habits fertilization, using the rice of the present invention
Special fertilizer can make increasing production of rice more than 7%, obvious effect of increasing production when nutrient dosage is identical.
