The fertilizing method of lotus is supported in a kind of potted plant pond
Technical field
The invention belongs to floriculture field, be specifically related to a kind of fertilizing method of cultivating lotus, the fertilizing method of lotus is supported in especially potted plant pond.
Background technology
Lotus (formal name used at school: Nelumbo nucifera), have another name called lotus flower, fragrant marshweed herb etc., Nymphaeales, the perennial aquatic and herbaceous flowers of Nelumbonaceae.Originate in Tropical Asian and Temperate Region in China, China just has cultivation to record as far back as the Zhou Dynasty, is one of China's ten large famous flowers.Subterranean stem is long and plump, has meropodium, and leaf shield is circular.Florescence 6, to September, is singly born in bennet top, and petal is most, and embedding life, in holder cave, has red, pink, white, purple isochrome, or has lathe work, fringing.Nut is oval, and seed is avette.
Lotus happiness is fertile, if be planted in the pond of humus plumpness, can not apply fertilizer.But in the north, the general foster method in potted plant pond that adopts of sight cultivation, man-made pond(pool) area is little, and aquatic animals and plants is few, and humus is few, needs artificially applying fertilizer.In traditional lotus cultivation, often only focus on supplementing the nutrient components such as nitrogen (N), phosphorus (P), potassium (K), and other nutrient components have been ignored, as calcium (Ca), magnesium (Mg), iron (Fe), zinc (Zn), manganese (Mn), copper (Cu), molybdenum (Mo) etc., what can cause that lotus can not be abundant, balanced obtains the required various nutrient components of growth, growth to its leaf, flower, fruit etc. has a negative impact, and reduces sight.In addition, overfertilization can be burnt seedling, therefore wants thin fertile duty to execute, and applies fertilizer targetedly according to the feature of different growing stages, in order to avoid cause waste or play negative interaction.
Summary of the invention
Technical problem to be solved by this invention is to provide the fertilizing method that lotus is supported in a kind of potted plant pond, adopt this fertilising scheme, can make lotus obtain fast, fully required nutrient component in each vegetative period, keep balanced in nutrition, normal growth, improves the ornamental quality of lotus leaves, flower, fruit.
The technical solution used in the present invention is:
A fertilizing method for lotus is supported in potted plant pond, comprises the following steps:
1), transplanting time
Before transplanting, apply the soya-bean cake fertilizer that becomes thoroughly decomposed as base fertilizer, during transplanting, in root week, apply root-growing agent;
2), seedling stage
When lotus grows the floating leaf of 4-5 sheet, applying phosphate fertilizer is main composite fertilizer: soon ammonium dihydrogen phosphate (ADP), potassium dihydrogen phosphate, superphosphate, boric acid, manganese sulphate, zinc sulphate, copper sulphate, molybdic acid, nickelous sulfate, NaFeDTPA, sodium silicate mix with soil, roll into a ball into 4-5 native ball, execute earth upper strata in basin; Apply fertilizer 2-3 time;
3), bud stage
After bud water outlet, apply phosphorus potash fertilizer: be about to the beancake powder that becomes thoroughly decomposed, urea, potassium dihydrogen phosphate, superphosphate, boric acid, manganese sulphate, zinc sulphate, copper sulphate, molybdic acid, nickelous sulfate, NaFeDTPA, sodium silicate mix, and are divided into 4-5 part, fill in basin mud; Apply fertilizer 3-5 time;
4), full-bloom stage
At full-bloom stage, apply composite fertilizer: be about to become thoroughly decomposed beancake powder, urea, potassium dihydrogen phosphate, superphosphate, boric acid, manganese sulphate, zinc sulphate, copper sulphate, molybdic acid, nickelous sulfate, NaFeDTPA, sodium silicate mix, and are divided into 4-5 part, fill in basin mud; Apply fertilizer 2-4 time;
5), bloom the later stage
Blooming, the later stage applies composite fertilizer: the beancake powder that is about to become thoroughly decomposed, urea, ammonium dihydrogen phosphate (ADP), potassium dihydrogen phosphate, superphosphate, boric acid, manganese sulphate, zinc sulphate, copper sulphate, molybdic acid, nickelous sulfate, NaFeDTPA, sodium silicate mix, be divided into 4-5 part, fill in basin mud; Apply fertilizer 1-2 time.
Particularly, the fertilizing method of lotus is supported in this potted plant pond, comprises the following steps: with diameter 50cm, and the earthen basin of dark 30cm, every basin one strain is benchmark:
1), transplanting time
Before transplanting, apply soya-bean cake fertilizer that 200-250g becomes thoroughly decomposed as base fertilizer, during transplanting, in root week, apply 1L root-growing agent;
The effect of this step is: short root strong sprout, improve survival rate.
2), seedling stage
When lotus grows the floating leaf of 4-5 sheet, applying phosphate fertilizer is main composite fertilizer: soon 12-17g ammonium dihydrogen phosphate (ADP), 10-15g potassium dihydrogen phosphate, 3-6g superphosphate, 50-70mg boric acid, 10-15mg manganese sulphate, 15-20mg zinc sulphate, 2-3mg copper sulphate, 2-3mg molybdic acid, 2-3mg nickelous sulfate, 0.5-0.7g NaFeDTPA, 3-4g sodium silicate mix with soil, roll into a ball into 4-5 native ball, execute earth upper strata in basin; Apply fertilizer 2-3 time;
The effect of this step is: promote the growth of root, stem, leaf, prevent yellow leaf, leaf roll, strengthen ability disease-resistant, resistant to lodging, improve plant vigor.
3), bud stage
After bud water outlet, apply phosphorus potash fertilizer: be about to the 100-150g beancake powder that becomes thoroughly decomposed, 5-8g urea, 15-20g potassium dihydrogen phosphate, 5-8g superphosphate, 0.1-0.15g boric acid, 10-15mg manganese sulphate, 15-20mg zinc sulphate, 2-3mg copper sulphate, 2-3mg molybdic acid, 2-3mg nickelous sulfate, 0.3-0.5gNaFeDTPA, 3-4g sodium silicate mix, be divided into 4-5 part, fill in basin mud; Apply fertilizer 3-5 time.
The effect of this step is: promote root system development, flower bud differentiation.
4), full-bloom stage
At full-bloom stage, apply composite fertilizer: be about to the 25-40g beancake powder that becomes thoroughly decomposed, 10-15g urea, 10-15g potassium dihydrogen phosphate, 5-8g superphosphate, 0.1-0.15g boric acid, 10-15mg manganese sulphate, 15-20mg zinc sulphate, 2-3mg copper sulphate, 2-3mg molybdic acid, 2-3mg nickelous sulfate, 0.3-0.5gNaFeDTPA, 3-4g sodium silicate mix, be divided into 4-5 part, fill in basin mud; Apply fertilizer 2-4 time.
The effect of this step is: promote the growth of leaf, flower, fruit, improve sight.
5), bloom the later stage
Blooming, the later stage applies composite fertilizer: be about to the 20-30g beancake powder that becomes thoroughly decomposed, 5-8g urea, 5-8g ammonium dihydrogen phosphate (ADP), 5-8g potassium dihydrogen phosphate, 2-5g superphosphate, 25-50mg boric acid, 3-5mg manganese sulphate, 8-12mg zinc sulphate, 1-2mg copper sulphate, 1-2mg molybdic acid, 1-1.5mg nickelous sulfate, 0.2-0.3gNaFeDTPA, 2-3g sodium silicate mix, and are divided into 4-5 part, fill in basin mud; Apply fertilizer 1-2 time.
The effect of this step is: promote plant continued growth, kind of blooming period prolonging.
More preferably, described root-growing agent is methyl α-naphthyl acetate 0.1-0.15ppm, indolebutyric acid 0.2-0.3ppm, the root-growing agent of 6-BA0.2-0.25ppm.
The beneficial effect that the present invention has:
The present invention supports the different growing stages of lotus in potted plant pond, for lotus supplements each growth stage desired nutritional composition, comprise macroelement and trace element, in conjunction with traditional root organic fertilizer, make lotus can obtain comprehensively, fully desired nutritional composition in each vegetative period, keep balanced in nutrition, guarantee the normal growths such as root, stem, leaf, fruit, be conducive to ornamental raising.
