Description
Technical field
The present invention relates to control of plant disease technical field.
Background technology
The control of rice disease ensures rice high yield and important means.Still there are some problems at present in the application of paddy rice plant protection technology, as medicament select improper, dispenser is inaccurate for period, causes effect of chemical control bad, and medicament effective dose and number of times can be made to increase, make the decline of Rice Resistance characteristic of disease, the increase of pathogen pesticide resistance etc., finally cause the paddy rice underproduction.Along with continuous differentiation and the improvement of culture technique, growing environment, the pathogen ecotope of paddy rice all change, add peasant household to rice cultivating technique grasp bad, cause that Han Didao district disease species increases, enlarged areas, harm aggravation, bring inestimable loss to Rice Production.Existing certain methods can not meet the needs of production, and does not note carrying out diagnosing, preventing and treating in disease generation early stage or initial stage in the process of preventing and treating.But do not propose in prior art to prevent and treat according to the fertility of paddy rice main stem leaf age.
Summary of the invention
The object of this invention is to provide a kind of prevention and controls of rice disease, to take leaf age diagnose method to prevent and treat rice disease, according to the fertility of paddy rice main stem leaf age, rice disease is is effectively prevented and treated.
The present invention solves the problems of the technologies described above the technical scheme taked to be:
A prevention and controls for rice disease, is characterized in that: described method takes leaf age diagnose method to prevent and treat rice disease; Rice Leaf is utilized to determine that rice disease control approach is the length of time: rice seedling blight control approach is the paddy rice 2 leaf phase; The control approach of oriental sesame leaf pinta is in the paddy rice 9.2 leaf phase; Leaf pest and bacterial brown spot control approach are in the paddy rice 9.3 leaf phase;
Sheath maize ear rot control approach is paddy rice booting initial stage and booting latter stage; The control approach of brown stain fringe is paddy rice booting latter stage and full heading time; Banded sclerotial blight control approach is paddy rice 10.1 leaf phase and booting stage.
30% auspicious seedling water cleaning agent 1.5ml/m is used in the rice seedling 2 leaf phase
2, control rice seedling blight (good to rice seedling blight control efficiency, seedling quality is good); 2% kasumin liquor 90 milliliters/mu is used, spouting liquid 20 liters/mu, water prevention rice brown spot (good to oriental sesame leaf pinta control efficiency) in the paddy rice 9.2 leaf phase; In the paddy rice 9.3 leaf phase, use 2% kasumin liquor 90 milliliters/mu, control leaf pest and bacterial brown spot; Use 43% latter stage at booting initial stage and booting and make every effort to overcome well suspending agent 20 milliliters/mu, spouting liquid 15 liters/mu, control sheath maize ear rot; 3% polyoxin aqueous solution 90 milliliters/mu is used, spouting liquid 15 liters/mu, control brown stain fringe in booting latter stage and full heading time; Use 24% full fringe suspending agent 20 milliliters/mu in paddy rice 10.1 leaf phase and booting stage, spouting liquid 15 liters/mu, prevents and treats banded sclerotial blight.
The base reason of the inventive method is as follows: the growing process of paddy rice main stem leaf age reflection paddy rice.By the investigation of Leaf ageeourse, the growing process each organ can be inferred, the diagnosis of Here it is growing process; Also can according to Leaf ageeourse at that time, the Leaf ageeourse of a period of time after inferring, thus infer the critical periods such as ear differentiation, jointing, reduction division, heading.For realizing the high-quality, highly efficient and productive of Rice Production, must apply fertilizer to its colony in good time, irrigating, the management of the aspect such as plant protection is most important.The control measures of Different Leaf Age phase, the effect produced also will show specific Leaf-Age-Period.Therefore, managing by main stem leaf age, is the best method guaranteeing promptness and accuracy.
Leaf age computational methods: N leaf exposes process leaf age from dew point to pulvinus calculates, and first estimates the length of N leaf.Method is: add 5 centimetres with the length of next leaf of N leaf, is N leaf length, then measures the physical length that N leaf is extracted out, then divided by the N leaf length estimated, as the ratio of N leaf length.As calculated the leaf age of the 5th leaf extraction, first the length of 5 leaves is estimated, sizing length as 4 leaves is 11 centimetres, add 5 centimetres, namely the estimation length of 5 leaves is 16 centimetres, if 5 leaves have extracted 2 centimetres out, with 2 divided by 16, equal 0.12, approximate 0.1, namely the 5th leaf has taken out 0.1 leaf age, the leaf age now investigated is 4.1 leaf age values.Make a record, be so calculated to three leaves reciprocal (11 leaf kinds be 9 leaves, 12 leaf kinds be 10 leaves) all by this method.2 leaves and sword-like leave, subtract 5 centimetres for estimated value by the fixed length of last leaf, actual extension elongation, divided by estimated value, obtains leaf age value at that time.The time of leaf age record is all investigation phase beginning with transplanting date, and once, investigation is to full heading time always in investigation in later every five days.
Rice disease occurs and paddy rice leaf age correlation: before mainly occurring in rice seedling with 11 leaf rice seedling blights, stand pin phase, 2 leaf phases and 3 leaf phases, oriental sesame leaf pinta occurs in paddy rice 5 leaf phase and the 10 leaves phase of launching respectively, leaf pest and the bacterial brown spot phase of starting mainly launches the phase at paddy rice 10 leaf, panicle blast starts the phase 8 days (full heading time) after Rice Heading, sheath maize ear rot mainly occurs in booting stage, brown stain fringe mainly occurs in full heading time, and banded sclerotial blight mainly occurs in sword-like leave extensin period.
The invention has the beneficial effects as follows:
The present invention, according to paddy rice main stem leaf age growing process dispenser diseases prevention, changes peasant in the past and leans on experience, sees that disease dispenser is accustomed to.It is exactly according to paddy rice main stem leaf age growing process that paddy rice leaf age diagnosis prevents and treats rice disease, select control approach dispenser diseases prevention, reduce spraying times, reach control efficiency, change peasant in the past to lean on experience, see that disease dispenser is accustomed to, peasant is freed gradually from the out-of-date methods in past (seeing calendar), and scientifically according to the fertility of paddy rice main stem leaf age, rice disease is is effectively prevented and treated.Control efficiency is see embodiments of the invention part.
