Abstract
The invention relates to a method for preventing and treating white spots of carica papaya fruits. The method comprises the following steps: trace element fertilizers (magnesium sulfate, ferrous sulfate, zinc sulfate, calcium nitrate or lime, foliage fertilizers and the like) are supplemented once every month one month after picking fruit of the carica papaya, after applying organic fertilizers, chicken manure and macroelement fertilizers such as N, P, K, B and the like, 30-60kg of the lime or 5kg of the calcium nitrate per mou is added to irrigation water for fertigation, the magnesium sulfate can be fertigated at 20-40kg/time per mou or broadcast, and soil is sprayed with water for more than 30 minutes to cause the fertilizers to dissolve into the soil after broadcasting; the fertigation concentration is not more than 0.1%, more than 10 liters of water is applied to each plant in combination with spraying 200-500 times of foliage fertilizers such as complex Fe, Mg, Ca, Zn, Mo, Cu, Mn and the like. The method can prevent and treat the white spots of the carica papaya fruits; whiten and fade fruit disease spots, turn the spots green, help the young fruit skin to normally develop into dark green, and improve the fruit quality.
Description
Technical field
The present invention relates to a kind of guard method of fruit, relate to a kind of method for preventing and treating melon tree fruit with leukodermic specifically.
Background technology
Papaya papaw Carica pa paya L. has another name called pawpaw, newborn melon, papaw, Caricaceae, and papaya papaw belongs to, and the evergreen tropical fruit tree of perennial herb originates in South America.Add up according to FAO in 2007: 371345 hectares of the area under cultivations of whole world papaya papaw, 6937097 tons of output, 5800 hectares in China, 145000 tons.Papaya papaw is nutritious, and vitamin content is very high, and is very popular, is called as the king of world's fruit nutrition, ranks first of the ten kinds of fruit comprehensive nutrients in the world.The papaya papaw purposes is wide, mellow fruit, and it is edible to make fruit, helps digest, controls stomach trouble; Immature Chinese olive, except that can do vegetables edible, also can pickle, preserved fruit, make jam and canned fruit juice, be again good feed; Chinese olive contains abundant papain simultaneously, and extensive use in medicine, food, process hides, weaving and beauty treatment is the primary raw material of papain industry.Papaya papaw has the cultivation history in more than 300 year in China, it is the tropical fruit (tree) of the tool development prospect of China, yet, the papaya papaw disease affects the agricultural production of papaya papaw, papaya papaw disease main harm has two aspects, on the one hand being the plant of harm fruit, is the harm fruit on the other hand, and that finds at present has a mosaic disease, eqpidemic disease, anthracnose etc., mosaic disease mainly are harm papaya papaw plant, their early stage, the water logging spot appears between the offshoot of stem, vein and tender leaf, occur the mosaic disease symptom on the anaphase blade, the blade major part comes off, and fruit also can be infected.Eqpidemic disease and the anthracnose fruit of mainly causing harm, and anthracnose a speciogenesis is general especially, the severe diseases that causes harm, not only cause harm fruit but also cause harm blade and vein.Virus disease has also been found in the papaya papaw producing region, has influenced the yield and quality of papaya papaw, has not only spread unchecked but also also seriously influenced in the U.S. plantation of papaya papaw in the South China.At some state of an illness, the researcher has carried out conscientious research, has found out the method for control, and the patent No. is that the patent of 02134731.X is reported at the method for preventing and treating of papaya virosis, a kind of method of preventing and treating of preventing and treating papaya virosis is provided, can the effectively preventing papaya virosis.
The papaya fruit Leucoplakia is newfound fruit physiological disease, does not appear in the newspapers so far, and the researcher finds that the generation of this disease has significant impact to fruit appearance quality, reduces the economic worth of fruit.The orchard of morbidity does not have the effectively preventing method at present, so that ripe pawpaw can not be sold, cause to lose and receive, main morbidity place comprises Le Dongxian spike town, Hainan Province, Huang Liu town, the town that benefits the nation, a plurality of pawpaws garden, Jiu Suo town, and susceptible kind has: No. 9, big Bai Piri liter, Malaysia.Disease tolerant variety has: rise rascal day, No. 2, little Bai Piri liter, fringe excellent No. 2 and platform farming, the Leucoplakia symptom is rounded, the oval patch of young fruit fruit surface, move back green bleaching, then fruit is covered with circular spot, serious plant white circular spot is practiced in flakes, inlays green color stripe, and fruit bagging also has scab, on the sunny side, the plant on mountain top is found earlier and is relatively more serious.Sick pericarp surface smoothing does not have depression, the fruit after-ripening, and the fruit disease portion that color spot is light and the color differentiating of strong portion are not obvious.The fruit that color spot is heavy is pale yellow color spot, can not change into golden yellow together with original green pericarp part, the greeny ring spot in edge, meat, local flavor, soluble solid and shelf life of sick fruit and normal fruit do not have significant difference, but because the difference of outward appearance, the procurement price in field is than normal low %30-50%, and economic benefit obviously descends.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can effectively prevent and treat the leukodermal method of papaya fruit, and can be widely used in the method for preventing and treating of agricultural production.
In order to achieve the above object, the technical solution adopted in the present invention is:
The amount of growth of papaya papaw is big, the output height, and part high yield plant can be received 20 kilograms of fruits every month summer, particularly after beginning to gather, must in time replenish the nutritive element of being taken away by fruit.So general pawpaw garden replenishes still timely macroelement.But the part trace element can not get replenishing.Therefore begin fruit picking one time every month microelement-supplementing fertilizer after 1 month plant: magnesium sulfate, ferrous sulfate, zinc sulphate, nitrate of lime, lime, foliage fertilizer etc.At organic fertilizer, chicken manure, behind the macroelement fertilizer such as N, P, K, B, lime by 5 kilograms in 30～60 kilograms every mu or nitrate of lime, to be sneaked into to irrigate in the irrigation water and executed, magnesium sulfate also can be irritated and be executed, and by 20～40 kilograms/time every mu, also can spread fertilizer over the fields.Having spread fertilizer over the fields fertile must the water spray was dissolved in the soil fertilizer more than 30 minutes.The concentration that filling is executed is not more than 0.1%, more than every strain 10 premium on currency.During the fertilising operation, fertilizer is dissolved in the fertilizer pond in proportion, in the pond, stir, dissolve, irrigate a few minutes of spraying water earlier, open the switch fertilising of fertilizer pond again, use sufficient (having sprayed rich water) by fertilizing amount and close fertile pond switch at last, allow water wash pipeline, spray band, shower nozzle and the face of land fertilizer of irrigation system.Time is assigned as: sprayed water in advance 5 minutes, and---fertile filling 25 minutes---washed 10 minutes.Foliage fertilizers such as combination with spraying 200～500 times of complexing Fe, Mg, Ca, Zn, Mo, Cu, Mn.Prevent the concentration of Leucoplakia spray foliage fertilizer to implement at ordinary times according to normal requirement.Magnesium sulfate and complex compound generally mix with borax and execute, ferrous sulfate not with other fertilizer mixed applyings, complexing iron and other chemical fertilizer are executed in that the dissolving back is mixed respectively.The plant that scab takes place was spread fertilizer over the fields magnesium sulfate 150 grams every 15 days, connect Shi Sanci, sprayed foliage fertilizers such as complexing Fe, Mg, Ca, Zn three times.
The beneficial effect that the present invention has is that the present invention can prevent and treat the papaya papaw Leucoplakia, and the fruit scab can be desalinated by hickie, changes green, and the young fruit pericarp development is normally dark green, improves the exterior quality of fruit, guarantees peasant's income.
