Young today assistant receives # of plan of # cereal abundant a paddy is planted of establish door leave a message, the paddy of his home appeared undesirable growth state, neighbour says to him, the likelihood was gotten establish withered disease, want to ask this how to differentiate does paddy stand withered disease and how prevent and to how prevent and prevent and cure?
Paddy establishs withered disease, paddy grows a kind of very common disease in the process, produce an area extensive, basically have in area of establish of water seed rice happen, affecting the crop of paddy, judgement paddy establishs withered disease to basically have at 3 o'clock, it is from the root the ministry analyses:
1, the paddy individual plant that surveys sicken, whether does root ministry have mildew layer?
2, the paddy individual plant that surveys sicken, whether color is Brown?
3, the paddy individual plant that surveys sicken, have cankered appearance?
Usually, be affected to establish the paddy of withered disease, root ministry can have Brown (or hoar) mildew layer appears, if root ministry is accompanying cankered phenomenon, explain already very serious, because establish withered sick early days cankered symptom is not quite apparent, once have decay, causing reduction in production is inevitable.
In cultivating a process actually, paddy establishs withered disease to be given priority to in order to prevent, main precautionary measures has at 4 o'clock:
1, sow density to cannot pass close, it is transplant or direct seeding no matter it is such, had sowed close rice field, produce the odds that establishs withered disease to be able to increase.
2, notice water fertilizer manages, this fill water wants seasonable fill water, this catchment wants seasonable drain off water, the use of fertilizer need not introduce too much, base fertilizer + top application + fertilizer of face of blade is same cannot little, the purpose is those who raise paddy seedling oneself fight a gender, increase the capacity of counteractive disease.
3, be aimed at transplant cropland, job of raise rice seedlings should reach the designated position, seedling the way corp is growing is exuberant, make sure transplant arrives after land for growing field crops, appear without weak seedling, facilitating seedling is fast turn green, tillering, reduce the descent of disease.
4, if had happened to establish the rice field of withered disease before, before growing rice, can undertake alexipharmic handling to soil, spirit of usable drug evil mildew, armour frost spirit, will reduce the odds that establishs withered ill happening with this.
Above 4 o'clock is precautionary measures, and field after once happen,establishing withered disease, want to hit medicine in time to undertake preventing and cure, had jumped over earlier.
Establish withered disease in the light of paddy, the drug on market also has many, common armour frost spirit and evil mildew are for instance clever, nevertheless, some places may be used for long, fight a gender bigger already, the proposal is used answer dispensation agent, armour frost · is for instance evil mildew spirit, Jia Shuang. Fu Meishuang, will improve result of prevention and cure with this.
Establish withered disease how to be judged about paddy and precaution and measure of prevention and cure, young assistant says so much, if you still have other experience of better prevention and cure, in welcoming to be commented on below, leave a message, everybody discusses study together.
