Problems solved by technology

[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.

Embodiment 3

[0031] (1) select a vigorous hydrangea plant;

[0032] (2) The soil for planting Hydrangea is selected from the mixed soil of red soil and leaf rot soil, the pH is 5.5, and the weight ratio of red soil and leaf rot soil is 2:1;

[0033] (3) select the NPK fertilizer that contains N, P, K for fertilization, and its weight ratio is N:P:K=5:5:30;

[0034] (4) The NPK fertilizer is made into a liquid and watered on the roots of the Hydrangea.

Abstract

The invention provides a hydrangea macrophylla color change method. The method includes the steps: (1) selecting strong hydrangea macrophylla plants; (2) selecting red soil and leaf mould mixed soil for planting hydrangea macrophylla; (3) selecting NPK fertilizers containing N, P and K for fertilizing, wherein N:P:K=(5-10):(5-10):30. Compared with the prior art, the hydrangea macrophylla color change method has the advantages that the problems of soil acidification, sulfur element increase and the like caused by application of aluminum sulfate can be avoided; more importantly, the hydrangea macrophylla can be effectively turned into cyan by a specific ratio of N, P and K, and buds are increased remarkably in size; in addition, N, P and K are major elements for plants, and application of the NPK fertilizers cannot 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...
