After typhonic rain passes, orchard of each district orange is different degree is damaged, stricken be hit by a natural adversity consequence farming the work resumes in busy orchard, and plant diseases and insect pests of gush drug prophylaxis and treatment. After this typhonic rain passes, and other places of Guangxi Wu city, He Zhou, guest, Guilin, orange occurrence doubt seems day bright ill question, but differ somewhat with common insolation disease written complaint, the reason is difficult affirmatory!
September 22, in this locality (Wu city cheats hill) the content that orchard of sanded candy orange collects, introduce according to orchard host, gush of typhonic a kind of green tea passes drug, farming a few kinds of drug that endowment inn helps a gush, oil having breed kind drug, after typhonic rain 34 days look to the orchard, the problem of discovery, blade and fructification have, have a common characteristic, it is to happen in face of exposed to the sun entirely.
Judge slight medicine one-sidedly to kill + day bright, chroma of medicine of gush of typhonic a kind of green tea is exorbitant, mix operable drug undeserved, liquid medicine is inhomogenous bring about slight medicine to kill, sun of consecutive fine day is violent after typhonic rain, day bright is brought about!
Orange fruit grower considers as disease, it is acute anthrax disease, judge according to face of blade, acute anthrax disease was contracted after considering as a typhoon rain, individual view is to disapprove of this viewpoint, because happen in face of exposed to the sun entirely, and the symptom of acute anthrax disease and this symptom also differ somewhat.
Yesterday, he Zhouzhao's smooth fruit grower, the sanded candy orange that oneself also discover after also discovering typhonic rain has this problem, saw the picture that he sends, with article photograph symptom almost same, according to his introduction, gush of his typhoon a kind of green tea medicine. Somebody considers as medicine to kill, somebody considers as day of bright disease, somebody considers as acute anthrax, somebody considers as air the bacterium, discuss more complex more occasionally. He filled later, prescription is commonly used, local typhoon a kind of green tea does not have the orchard of gush medicine, also appeared this problem.
Yesterday, the fruit grower of guest gold show says, the sun of typhonic a kind of green tea is so fierce, oneself fertile mandarin orange is little also day bright is ill, two days are basked in to appear a lot of days after typhonic rain bright is ill, it is to do really do not understand!
The reason follows typhonic rain + day bright is concerned, but analytic also do not come out, send friend ring, discuss this issue, did a dilettante person say a word " had seen water knife? Strength enough iron can cut off, the rain below the typhoon also has particular strength, also have certain harm to orange. Also have certain harm to orange..
Symptom of orange occurrence above, had not had commodity value, the proposal is excised, after typhonic rain antiseptic kill insect. According to the view of oneself and friend, summary reason is as follows: One, typhonic a kind of green tea has slight medicine to kill, the symptom is not apparent, add bright of day of the high temperature after rain through typhonic rain, appear this symptom. 2, typhonic rain has harm to orange, the principle of water knife, add bright of day of the high temperature after rain. 3, it is so inside chamber fruit, never the sun is point-blank over- , the belt after the typhoon passes comes out, encounter bright of high temperature day to be basked in bad.
