Abstract
The invention discloses a rice disease prevention and treatment method and belongs to the technical field of crop disease prevention and treatment. The rice disease prevention and treatment method comprises the following steps of seed treatment, leaf cooling treatment, leaf blast prevention and treatment, rice false smut prevention and treatment, and irrigation and drainage treatment. An acetic acid and strong chlorine mixed solution is used for conducting seed soaking treatment, the rice morbidity is reduced, large-area generation of various diseases of rice is effectively restrained, and therefore the rice yield is improved.
Description
Technical field
The invention belongs to crop disease control technical field, particularly one prevents and treats rice disease method.
Background technology
Paddy rice is the one of draft Oryza, is also the longest main one as grain in Oryza, for annual, gramineous plants, unifacial leaf, property happiness is warm and humid, is the main food of people's daily life, paddy rice about contains the starch of more than 75%, the protein of about 8%, the fat of 0.5 ~ 1%.Still containing a small amount of B family vitamin; The content of vitamin is different because of the kind of rice and plantation place.Also containing multiple organic acids such as acetic acid, fumaric acid, succinic acid, Glycolic acid, citric acid and malic acid, the monose such as glucose, fructose, maltose.
Rice blast is one of important disease of paddy rice, can cause the significantly underproduction, and the underproduction 40% ~ 50% time serious, even No kernels or seeds are gathered, as in a year of scarcity.This disease all has generation in various places, wherein occurs as many with leaf portion, joint portion, can cause the underproduction in various degree after generation, and especially panicle blast or joint pest occur early and weigh, and can cause dead ears so that total crop failure, at present, rice blast may occur in any region and any season.
Bakanae disease is sick also known as excessive growth, and all there is generation in Chinese Ge Dao district.Sick grain is broadcast rear often germination and maybe can not be unearthed.Disease of falling ill seedling stage seedling is thinner and taller than strong seedling, and blade leaf sheath is elongated, and leaf look yellowish, and root system development is bad, and the sick seedling of part is dead before transplanting, and withered seedling has light red or white mould powder.
The microbial crop pest of various cause of disease greatly affects grain-production, and crop failure, grain quality are declined.
Summary of the invention
The object of the invention is to: for above-mentioned Problems existing, the invention provides one and prevent and treat rice disease method, plant physiology function can be regulated, strengthen crop disease-resistant anti-adversity, there is bactericidal, and there is the feature such as resistance of rainwater washing against, lasting period length.
Technical scheme of the present invention is: one prevents and treats rice disease method, comprises the following steps:
1), seed treatment: prior to seeding, Cotton seeds is carried out to the rice paddy seed before sowing or uses acetic acid and strong chlorine oil mixed solution to carry out seed soaking;
2), blade cooling process: in the shooting stage, carry out blade spraying ethanolic solution in every 10-15 days;
3), leaf seasonal febrile diseases control: leaf seasonal febrile diseases are when occurring sick leaf or infection center, and mu 40-60ml doubly sprays to water 1000 containing 25% Prochloraz missible oil medicine; Panicle blast is before cut heading and Qi Suihou, and a point secondary carries out emphasis prophylactic treatment to fringe portion, and mu 80-100ml contains 25% Prochloraz missible oil medicine to the spraying of 800 times, water;
4), false smut control: in the booting later stage, 5-7 days before cut, dosage is suitably strengthened in control panicle blast basis, and as many days overcast and rainy during heading flowering, answer emphasis to spray medicine protection, mu contains 25% Prochloraz missible oil to the spraying of 800 times, water with 100;
5), fill with drainage sunk well: respectively the process of draining dry field is carried out to paddy rice field at tillering stage of paddy rice, shooting stage and full heading time, drained by the water in rice field and carry out dry field, continue after continuing 2-3 days to fill with shallow water.
Further, described step 1) the seed soaking Yangtze river basin and areas to the south soak seed 24 hours, and the Northeast soaks seed 48 hours at 36 hours Huanghe valleys of soaking seed.
Further, described step 2) ethanolic solution be the ethanolic solution of percent by volume 20%-30%.
In such scheme, step 1) seed carries out seed soaking, and can kill the rice blast fungus spore that the surface of the seed may carry, reduce probability of catching an illness seedling stage; 25% used Prochloraz missible oil medicine, it is suppress ergosterol biosynthesis, has protection and eradicant action, has remarkable preventive effect to various crop sac fungi and imperfect fungus disease.Plant physiology function can be regulated, strengthen crop disease-resistant anti-adversity, volume increase of enlarging afforested area, and there is the feature such as resistance of rainwater washing against, lasting period length.
Beneficial effect of the present invention is: one of the present invention prevents and treats rice disease method, uses acetic acid and strong chlorine oil mixed solution to carry out seed soaking, reduces the probability of rice pathogenesis, effectively suppresses the large area of the various disease of paddy rice to occur, thus improves rice yield.

In order to better the present invention is described, do following field trial:
Test paddy field carries out, experimental field middle fertility, and water conservancy irrigation and drainage facility is general, point four regions, and one of them region is conventionally planted, last night control group, other three ground use embodiment 1-3 rice cultivation respectively, get the mean value of twice investigation.Test repetition 3 times, averages.
In units of strain, 5 samplings, investigate 5 clumps that are connected, totally 25 clumps at often, record investigation total strain number, diseased plant rate and sick progression.Carry out severity Scaling according to rice leaf sheath and blade disease symptom, severity Scaling standard is as follows:
0 grade: complete stool is anosis, plant is healthy;
1 grade: 4th blade and following leaf sheath thereof, blade morbidity (be 1st slice leaf with sword-like leave);
3 grades: 3rd blade and following leaf sheath thereof, blade morbidity;
5 grades: 2nd blade and following leaf sheath thereof or blade morbidity;
7 grades: sword-like leave blade and following leaf sheath thereof, blade morbidity;
9 grades: complete stool morbidity, withered ahead of time.
Plant number × 9 of disease index=∑ (the sick number of sheets × relative disease progression at different levels) × 100/ always investigation
Control efficiency (%)=(CK-PT) × 100/CK,
In formula, CK and PT is respectively the disease index of check plot and test region, and what the calculating of control efficiency adopted is the formula not investigating state of an illness radix before process.
Result of the test shows:
Check plot rice disease incidence average out to 68.7%, disease index average out to 6.25; Through the test region of embodiment process, disease index average out to 1.96, average control efficiency is 68.64%.Illustrate that the present invention has good inhibitory action, at the damage by disease and insect of paddy rice actual production control paddy rice, the output of paddy rice can be improved.
