Description
Technical field
The present invention relates to agricultural technology field, specifically a kind of special fertilizer rich in selenium of Oryza sativa L..
Background technology
Selenium element is one of required important trace element of human physiological activity, but selenium cannot synthesize in human body, human body
Picked-up to selenium element is mainly derived from the enrichment of plant Se in Environment to external world, metabolism and converted product, and therefore, human body is for selenium
The main source that element is taken in is food.
Along with the raising of people's living standard, people are more and more higher to the quality requirements of rice.Oryza sativa L. is to weigh in the world
One of cereal crops wanted, rice is one of main source of South Asia, Southeast Asia and Chinese people's nutrition and energy, its selenium content
Height is closely related with human nutrition situation.There is the population of nearly 2/3rds in China with rice as staple food.But China is large-area
Soil belongs to Que Xihuodi selenium district, and most of rice of production all belong to scarce selenium rice.Most area rice selenium content is
0.011-0.055mg/kg, average out to about 0.025mg/kg, less than normal contents 0.04-0.07mg/kg of China's grain selenium
Standard.Expection content demarcated by the Chinese Academy of Agricultural Sciences GB13105.1991 standard regulation selenium-rich people's rice is 0.2-0.31mg/kg.
On Oryza sativa L. selenium-enriching cultivation technology is applied, what at present research was more is Foliar application of selenium, to the research of soil spraying selenium relatively
Few, and soil is the main source of selemium nutrition.It is to be solved that soil spraying selenium presently, there are following difficult point: input amount is big, and dosage is difficult
Control, environment is easily caused pollution etc..
At present, the most also there is no a kind of selenium-rich medicine fertilizer being exclusively used in Oryza sativa L..
Summary of the invention
Solving the technical problem that of the present invention is to provide a kind of special fertilizer rich in selenium of Oryza sativa L., can not only efficiently control water
Rice disease, it is provided that the nutrient needed for Oryza sativa L., and can the higher high quality white rice of output Se content.
The technical solution used in the present invention is as follows:
A kind of special fertilizer rich in selenium of Oryza sativa L., comprises the following raw materials by weight percent: chitin 10-20%, phenyl allyloxy thiophene
Azoles 0.5-1%, humic acid 40-50%, nitrogenous fertilizer 1-1.5%, phosphate fertilizer 0.7-1%, potash fertilizer 0.5-0.6%, sodium selenite 0.2-
0.5%, zinc fertilizer 0.01-0.02%, boron fertilizer 0.02-0.03%, excipient supplies 100%.
Described excipient refers to fertilizer rich in selenium to make the auxiliary agent needed for granule or carrier.
Further, the part by weight of described chitin, probenazole and humic acid is 20-40:1-2:80-100.
As optimal case, the part by weight of described chitin, probenazole and humic acid is 30:1:80.
Compared with prior art, the present invention possesses and provides the benefit that:
(1) indoor biometrics result shows, by chitin, probenazole, humic acid mixture according to a specific ratio to rice blast
The suppression potentiation of pathogenic bacteria is obvious, and not only control effect is good, and advantageously reduces applications of pesticide amount and reduce pesticide cost.
(2) present invention is specifically directed to Oryza sativa L. and design, and fertilizer integrated with pesticide in one and is made granule spreads fertilizer over the fields, it is possible to subtract
Light farming operation, time and labour saving is laborsaving.
(3) fertilizer rich in selenium rice-cultivating of the present invention is utilized, it is possible to produce the selenium-rich high-quality rice that selenium content is higher.
Detailed description of the invention
Below in conjunction with embodiment, technical scheme and beneficial effect are described further, of the present invention hundred
Proportion by subtraction, in addition to Special Statement, is all weight percentage.
One, chitin, probenazole and humic acid and the built agent Toxicity Determination to rice blast
After prerun determines each medicament effective inhibition concentration scope, by chitin, probenazole and humic acid and mixed
Ingredients presses active constituent content gradient series 5 concentration of dilution, if clear water comparison.With reference to " farm-chemical indoor determination test standard
Then antibacterial " carry out, use mycelial growth rate method to measure the medicament virulence to rice blast.Measure by decussation method after 72h
Colony diameter, calculates each process net growth, mycelial growth inhibition rate.
Mycelial growth inhibition rate is converted into probit value (y), and liquor strength (μ g/mL) is converted into logarithm value (x), with minimum
Square law tries to achieve virulence regression equation (y=a+bx), and thus calculates the EC of every kind of medicament50Value.
It is antagonism that co-toxicity coefficient method (CTC) according to the abundant method of Sun Yun evaluates the potentiation of pharmacy mix, i.e. CTC≤80
Effect, 80<CTC<120 is summation action, and CTC>=120 are potentiation.Statistical result is as shown in table 1:
Measurement result shows, when the part by weight of chitin, probenazole and humic acid is 20:0.5:80, in addition
Effect；When the part by weight of chitin, probenazole and humic acid is 20:2:50, in antagonism；During other weight ratios,
Being shown as potentiation, wherein part by weight is that 30:1:80 potentiation is the most obvious.
