A lot of mango grow period of time before door ask " the mango of my home how does fruit begin to blacken from interior, cankered, expand gradually peel, what reason be? " , encounter disease of mango black heart, a lot of fruit grower see fruit have a problem, go blindly making agriculture chemical, is not go seeking an issue from general management.
Produce relatively serious main concentration to be in at present Sichuan, Yunnan, wait for the variety with bigger gains to happen with Kate, Ji Lu, Jin Huang again heavier.
Black heart disease is a common only say, also be called " soft nose is ill " . Appear in left and right sides of a week after Xie Hua commonly, mango interior submits form of water be soiled, subsequently all round embryo nigrescent, below damp environment, can have purulent liquid of black, 5 days or so diffuse peel surface, ill following defect, fruit handle falls off, serious Shi Quanshu young fruit all drops.
Measure of prevention and cure of disease of mango black heart:
Disease of mango black heart is managing fluctuation to weigh time, florescence, young fruit period inchoate precaution is crucial, fruit grower people the period using drug that did not ignore a key certainly, do not wait on ill go using drug passively again, use medical cost not only tall, return the result that short of expects. Of course although go up ill also had be toed treat, can increase concentration with preparation of Chinese herbal medicine, shorten interval period goes using drug, security of preparation of Chinese herbal medicine is high, the sensitive period that can grow in crop uses drug, place of traditional and chemical medicine cannot reach this.
Fat to phosphorous potash fertilizer, boron demand is more when mango blossoms, blossom around attention is additional phosphor, Potassium, boracic, zinc, molybdenum the microelement in waiting, beautiful fruit of preparation of each sparge Chinese herbal medicine is installed 150, 300 times + soil fertility flourishing 300 times, among them answer match Wo Feng element 1 times 600 times. The high energy material such as the amino acid in preparation of Chinese herbal medicine, polysaccharide, calcic, zinc and in microelement, enhance its to fight go against force of gender, immunity, benefit resists at mango florescence undesirable climate, stimulative pollination be fertilized, reduce abnormal fruit, fruit defeating Yo to appear, still can promote fructification chromatic, enhance waxiness layer ply, it is good to make fructification expresses light, big, raciness; If florescence appears,spend corrupt, can keep away from fill florescence to use drug, at the same time answer distribute garlic oil 1500 times. Still can prevent the happening of common disease on the mango such as disease of mango horn spot, anthrax disease effectively.
Fruit period of young fruit and Peng, need much nutrient material, must complement sufficient calcium is fat, install 2~3 of 300 times sparge with beautiful fruit second, among them answer match Wo Feng element, when necessary can the calcium that gush applies chela to join state is fat, benefit is formed at wall of young fruit cell and cellular film, enhance peel ply, stimulative fructification is normal development.
In addition, need controls nitrogenous fertilizer employ to measure, flourishing of a few the way corp is growing, Xie Se is deep the awn fruiter with deep layer of green, earth suggests to should apply nitrogenous fertilizer less, or not employ, with microbial bacterium fertilizer abstruse farming happy, organic fertilizer is given priority to, abstruse farming fertilizer of happy microbial bacterium can reform edaphic granule structure, stimulative root system grows, what contain among them is beneficial microbial it is all round root border decide breed quickly, form take an advantage, restrain plant diseases and insect pests invade catch, enhance tree body to fight go against a gender.
Disease of mango black heart produces an account:
Black heart disease happens to still basically cultivate body nutrition lopsided, nitrogen, phosphor is overmuch, inadequacy of the microelement in waiting brings about calcic, magnesian, boracic, zinc, manganese.
In addition still wait with condition of temperature, illumination, precipitation, soil about, general and acidity soil and sandy soil hair get a severe disease; Amount of employ of dung of nitrogenous fertilizer, chicken is large, if the gallinaceous dung of employ is sufficient become thoroughly decomposed, burn a root easily, still can carry egg of bacteria, bug, cause certain harm to establishing system, cause tree situation ability of weak, disease-resistant is reduced; Nitrogenous fertilizer is used overmuch, calcic, boracic complement of the microelement in waiting is not seasonable, bring about the flourishing that establish system to grow, immune force is reduced, at the same time Jie fought the absorption to calcic element, bring about cellular wall not thick, fructification skin is not thick, fight a gender low, light touch is ill, .
If encounter microtherm overcast and rainy,open florescence, bring about pollination be fertilized undesirable, embryonic development is undesirable bring about blacken, relative humidity of a few orchards comes on higher heavier.
