To cultivate potted camellia, the following three points should be noted:
Nitrogen fertilization spring shoots camellia generally start sprouting at 18 °C. The branches are smoked twice a year for the first time in spring (about mid-March to mid-April) and called "Spring Shoots"; the second time in summer (about mid-July to early September). "Summer tip; the second time in the spring (about mid-July to late September), called "summer tip." Branches with flower buds generally do not germinate summer shoots. The flower buds of camellia grow in the spring Therefore, raising the spring shoots is the key to whether or not the camellia flower can be grown well.When the spring shoots begin to germinate, nitrogen fertilizer is the main precipitating fertilizer, once every 10 days, until the spring shoot starts In the condition, it is also possible to apply foliar spraying with 1,000 times more potassium dihydrogen phosphate, about 0.1% urea, and about 300 times less rice vinegar mixed with diluted solution. After so many root and root fertilization, the spring of camellia The tip will grow very lush and the leaves can reach the maximum limit.
Phosphorus and potassium promote flower bud Camellia in the spring tipping foot, into the lignification, there will be a short period of dormancy. The beginning of the dormancy period is the beginning of the flower bud differentiation stage in which camellia is transferred from vegetative growth stage to reproductive growth. At this time, we must not apply nitrogenous fertilizer, but we must change phosphorus and potash fertilizer once every 10 days. At the same time, foliar sprays were performed using 1000-fold potassium dihydrogen phosphate, a small amount of borax and rice vinegar mixed with a diluted solution. This can not only control the camellias, but also can promote flower bud differentiation and shorten the time of flower bud differentiation, improve the effect of plants on photosynthesis, promote the synthesis of carbohydrates, flower bud differentiation and bud formation.
Leaving buds to protect the flowers Camellia cultivated by the above method can form a large number of buds, and then the buds will quickly expand, to be carried out in the late mid-August, a sparse buds, generally one branch of the big seedlings can leave two buds, each branch of the small seedlings only Leave a bud, and make the size of buds spread evenly to extend the time of flower viewing. After sparse buds, several thin phosphate fertilizers may be applied between September and October, and proper shading should be taken care of, especially against the western sun. Watering should be done so as to “never dry or pour,†so that the pots and soils are kept in a state of “see and see wet†to prevent the buds from falling off or being burnt.
In addition, the Camellia is a hi acidic flower. In order to reform the pH of the potted soil, a thin ferrous sulfate water should be applied every 20 days during the growth period to keep the leaves green and green, and to promote the plants to be robust and attractive.
