Description
Technical field
The present invention relates to agricultural technology field, specifically a kind of Oryza sativa L. selenium-enriching cultivation method.
Background technology
Selenium is a kind of important biological element, has great impact to the health of humans and animals, but organism is not
Itself can synthesize selenium, so the selenium in organism mainly passes through food intake.Therefore, food selenium content directly affects human body selenium
Trophic level.
China belongs to scarce selenium country, has 72% soil to belong to low selenium or scarce selenium soil, this means that on this soil
Plantation crop selenium content also very low it is impossible to meet needed by human body, so it is raw for enriching external source selenium to increase the selenium content of plant
Produce the main path of Se-rich farm products, be also the common methods manually producing Se-rich farm products at this stage.
Rice is the main meals of China resident, and Semen oryzae sativae rich in selenium is to pass through the fertile life of artificial interpolation selenium during paddy growth
Produce the Oryza glutinosa of selenium-rich, the selenium in Semen oryzae sativae rich in selenium is mainly existed with organic selenium form according to the study, so Semen oryzae sativae rich in selenium is a kind of safety
The selenium-enriched food of nutrition.Therefore pass through to increase Oryza sativa L. Se content, the intake improving human body selenium in the way of improving diet is slow
Solution human body lacks the effective means of selenium.
Content of the invention
The technical problem to be solved of the present invention is to provide a kind of Oryza sativa L. selenium-enriching cultivation method, can not only efficiently control
Rice disease, provides the nutrient needed for Oryza sativa L., and being capable of the higher high quality white rice of output Se content.
The technical solution used in the present invention is as follows：
A kind of Oryza sativa L. selenium-enriching cultivation method, concretely comprises the following steps：
(3) 7-10 days after transplanting, every mu is spread fertilizer over the fields fertilizer rich in selenium 70-100kg；
(4) in Rise's boot period, every mu is spread fertilizer over the fields fertilizer rich in selenium 80-120kg；
Fertilizer rich in selenium described in step (1) and step (2) comprises the following raw materials by weight percent：Chitin 10-20%,
Probenazole 0.5-1%, humic acid 40-50%, nitrogenous fertilizer 1-1.5%, phosphate fertilizer 0.7-1%, potash fertilizer 0.5-0.6%, Monohydrated selenium dioxide
Sodium 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 be made auxiliary agent or the carrier needed for granule.
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 beneficial effect that the present invention possesses is：
(1) indoor biometricses result shows, by chitin, probenazole, humic acid according to a specific ratio mixture to rice blast
Substantially, not only control effect is good for the suppression potentiation of pathogenic bacteria, 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 and is spread fertilizer over the fields, can subtract
Light farming operation, time and labour saving is laborsaving.
(3) present invention can produce the higher selenium-rich high-quality rice of selenium content.
Specific embodiment
With reference to embodiments technical scheme and beneficial effect are described further, of the present invention hundred
Divide ratio in addition to Special Statement, be all weight percentage.
First, chitin, the probenazole and humic acid and built agent Toxicity Determination to rice blast
Determine through prerun after each medicament effective inhibition concentration scope, by chitin, probenazole and humic acid and its mixed
Ingredients is pressed active constituent content gradient series and is diluted 5 concentration, if clear water comparison.Reference《Farm-chemical indoor determination test is accurate
Then antibacterial》Carry out, the virulence to rice blast for the medicament is measured using mycelial growth rate method.Measured with crossing method after 72h
Colony diameter, calculates each process net growth, mycelial growth inhibition rate.
Mycelial growth inhibition rate is converted into probit value (y), 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.
Evaluating the potentiation of pharmacy mix, that is, CTC≤80 are antagonism to co-toxicity coefficient method (CTC) according to the abundant method of Sun Yun
Effect, 80<CTC<120 is summation action, and CTC >=120 are potentiation.Statistical result is as shown in table 1：
Measurement result shows, the part by weight of chitin, probenazole and humic acid is 20:0.5:When 80, in addition
Effect；The part by weight of chitin, probenazole and humic acid is 20:2:When 50, in antagonism；During other weight ratios,
It is shown as potentiation, wherein part by weight is 30:1:80 potentiations are the most obvious.
