[0004] At present, the discoloration of hydrangeas is mainly caused by watering aluminum sulfate, but aluminum sulfate is an acidic substance. If it is applied too much, it will have a negative impact on the texture of the soil and other substances in the soil, and increase the amount of sulfur, which will affect the growth of plants. Growth, and the application of aluminum sulfate will only deepen the blue color of the hydrangea, and cannot achieve the effect of completely changing the color

Embodiment 1
[0021] (1) select a vigorous hydrangea plant;
[0022] (2) The soil for planting Hydrangea is selected from the mixed soil of red soil and mulch soil, the pH is 5.0, and the weight ratio of red soil and rot leaf soil is 1:1;
[0023] (3) select the NPK fertilizer that contains N, P, K for fertilization, and its weight ratio is N:P:K=5:5:30;
[0024] (4) The NPK fertilizer is made into a liquid and watered on the roots of the Hydrangea.
Embodiment 2
[0026] (1) select a vigorous hydrangea plant;
[0027] (2) The soil for planting Hydrangea is selected from the mixed soil of red soil and leaf rot soil, the pH is 6.0, and the weight ratio of red soil and leaf rot soil is 3:1;
[0028] (3) select the NPK fertilizer that contains N, P, K for fertilization, and its weight ratio is N:P:K=10:10:30;
[0029] (4) The NPK fertilizer is made into a liquid and watered on the roots of the Hydrangea.

Abstract
The invention provides a method for changing the color of hydrangea, comprising the following steps: (1) selecting a healthy hydrangea plant; (2) selecting a mixed soil of red soil and humus soil for planting hydrangea; (3) selecting a mixed soil containing N , P, and K NPK fertilizers for fertilization, and the weight ratio is N:P:K=(5-10):(5-10):30. Compared with the prior art, the hydrangea discoloration method of the present invention can not only avoid the phenomena such as soil acidification and sulfur element increase caused by the application of aluminum sulfate, but the most important thing is that the specific ratio of N, P, and K in the fertilizer can effectively use The color of the hydrangea has changed to blue, and the buds have increased significantly. In addition, NPK is a large amount of elements required by plants, and the use of the NPK fertilizer of the present invention will not cause negative effects on plant growth.
Description
technical field [0001] The invention relates to a method for changing the color of hydrangeas, which belongs to the field of flower planting. Background technique [0002] Hydrangea (scientific name: Hydrangea macrophylla), also known as hydrangea and hydrangea, is a plant of the genus Hydrangea in the saxifrage family. The Hydrangea flower is white and plump, large and beautiful, and its flower color can be red or blue, which is pleasing to the eye and refreshes the mind. It is a common potted ornamental flower and tree. The hydrangea was cultivated in China earlier, and the hydrangea was planted in the gardens in the south of the Yangtze River built in the Ming and Qing Dynasties. The parks built in the early 20th century are also inseparable from the planting of hydrangeas. Modern parks and scenic areas are planted in patches to form a landscape. [0003] Hydrangea likes warmth and humidity, is not resistant to drought, and avoids waterlogging; likes a semi-shady envir...
