Abstract
The invention relates to a method for preventing and treating calathea rotundifolia cv.fasciata leaf spot, which is characterized in that turfy soil Klasmann No. 414 is used as a culture substrate; the temperature is controlled at 22-28 DEG C in the day and 20-25 DEG C in the night, and the humidity is controlled at 75-85 percent in the day and 80-95 percent in the night; solution prepared by dissolving 0.2-0.4 gram of urea, 0.2-0.4 gram of monopotassium phosphate and 0.1-0.2 gram of micronasole into 100 L of water is sprayed at the time before sunlight irradiates plants in the morning once a month from plantlet introduction to sale; when an EC (earth current) value of soil is more than 0.12, clear water is sprayed, and when the EC value of the soil is less than 0.25, 1-1.2 g/L of a water solution containing peters professional 20-20-20 or 0.8-0.9 g/L of a KNO3 water solution is sprayed alternatively, wherein the peters professional 20-20-20 comprises the following components in percentage by weight: 20% of total nitrogen, 8.04% of ammonium nitrogen, 11.96% of nitrate nitrogen, 0.02% of boron, 0.01% of chelate copper, 0.10% of chelate iron, 20% of water-soluble phosphoric anhydride, 0.056% of chelate manganese, 20% of water-soluble potassium oxide, 0.01% of molybdenum, 0.25% of water-soluble magnesium oxide, 0.0162% of chelate zinc, and the balance of water.
Description
Technical field
The invention belongs to field of plant growing technology; Calathea orbifolia culture technique field particularly.
Background technology
States such as the original tropical America of Calathea orbifolia Brazil are screened cultivation and are formed by Europe (Belgium, Holland) people from roundleaf arrowroot original seed.The property half how wet cloudy environment of happiness high temperature, chilly is cold, avoids high light, blade length was opened the night blade and was closed up daytime.18 ℃ to 30 ℃ of growth thermophilics require relative air humidity higher, avoid basin soil and environmental drying.Leaf perfectly round, the food value of leaf is plump, the leaf look verdant, is arranged with neat striped on it, has high ornamental value, and is lovable especially.More furthermore relatively happiness is cloudy, is suitable for the long period to do potted plant viewing and admiring indoor.Because its blade is very large, strain shape is vigorous, and it is planted in large-scale wide-mouth flowerpot, can be used for arranging large-scale public places such as market, hotel, meeting room, reception room.With middle-size and small-size exquisite pottery pot plantation, then be suitable for doing general parlor, study, bedroom ornaments at home, a kind of sentiment is not arranged yet.
Because Calathea orbifolia is a kind of new varieties from external introduction; At present a spot of listing can be seen in domestic several flowers wholesale market few in number, domesticly just introduces, and is less at the culture technique area research; Therefore also there is certain defective in China's flower characteristic; Finished product like listing is spent and the large-area yellowish-brown spot of blade often occurred, and promptly so-called leaf spot is particularly in the listing of " May Day " " 11 "; This situation has had a strong impact on the Calathea orbifolia quality, has reduced its economic worth.
Summary of the invention
The present invention is intended to overcome the deficiency of prior art, and a kind of method that prevents the Calathea orbifolia leaf spot is provided.
The method of control Calathea orbifolia leaf spot is characterized in that cultivation matrix is turfy soil Klasmann414 number; 22-28 ℃ of temperature daytimes; 20-25 ℃ of nights, humidity daytime 75%～85%, night 80%～95%; From introducing seedling to selling spray in every month 1 time with the potassium dihydrogen phosphate of the urea of 0.2-0.4g and 0.2-0.4g and reach the peaceful 0.1-0.2g of gram and be dissolved in the solution that is made into the 100L water, the fertile time of spray be morning sunlight shine plant and do not carry out before; Water as follows during this period or water fertilizer: as the EC of soil value>0.25 the pouring clear water,<0.25 o'clock with containing the flower the more aqueous solution or the 0.8-0.9g/L KNO of 20-20-20 1-1.2g/L for the EC value of soil
3The aqueous solution pouring of rotating; Described flower the more 20-20-20 composition and percentage by weight is: full nitrogen 20%, wherein: ammonium nitrogen, 8.04%, nitrate nitrogen 11.96%; Boron 0.02%, copper (huge legendary turtle is closed attitude) 0.01%, iron (huge legendary turtle is closed attitude) 0.10%, water-soluble phosphoric anhydride 20%; Manganese (huge legendary turtle is closed attitude) 0.056%, water soluble oxidized potassium 20%, molybdenum 0.01%; Water soluble oxidized magnesium 0.25%, zinc (huge legendary turtle is closed attitude) 0.0162%, water surplus.
Leaf spot does not take place in the blade of using the Calathea orbifolia that the present invention cultivated, and is best in quality during list marketing, and blade is light green, can not curl for a long time, and appreciative value is strong, has higher prospect for sales.
Embodiment
Example 1
Test material is to introduce Calathea orbifolia 400 strains from Holland, and cultivation matrix is the turfy soil Klasmann414# from German import, and separating tests group and control group make an experiment for two groups, every group 200 strain.
Experimental group: strict control temperature and humidity; 22-24 ℃ of temperature daytimes, 20-22 ℃ of nights, humidity; Daytime 75%～78%; Night 80%～83%, from introducing seedling to selling spray in every month 1 time with the potassium dihydrogen phosphate of the urea of 0.2g and 0.2g and reach the peaceful 0.1g of gram and be dissolved in the solution that is made into the 100L water, the fertile time of spray be morning sunlight shine plant and do not carry out before.Normally water fertilizer during this period, promptly do not water, water the principle that then irrigates, as EC value > according to not doing; 0.25 the pouring clear water,<0.25 pouring nutrient solution is with spending the more 20-20-20 (component content is seen table one) 1g/>L or 0.8g/L KNO for the EC value
3The solution pouring of rotating.
Control group: strict control temperature and humidity, on 20-22 ℃ of temperature daytimes, at 18-20 ℃ of nights, humidity is normally watered or fertile daytime 75%～85% night 85%～90%, does not promptly water according to not doing, and waters the principle that then irrigates, as EC value>0.25 the pouring clear water is as EC value<0.25 pouring 0.6-0.7g/L KNO
3Solution.
Result of the test: the Calathea orbifolia of experimental group plantation, best in quality, and also blade is light green; Can not curl for a long time, appreciative value is strong, and the green apple of control group plantation; Plant has 5～8 blades the yellowish-brown spot to occur from introducing back growth in the time of 4 months in every strain, when plant strain growth to 8 month; Except that the young leaves that does not launch fully, large tracts of land yellowish-brown spot has appearred in other blade, and whole plant loses ornamental value.
