How to graft green flowers and Qionghua and control diseases and insect pests

Qionghua seedlings usually take seven to eight years to bloom, and if they are grafted with branches that grow into geranium buds, they can blossom in a good year after survival. How does the grafting method work? The following is for everyone. Grafting methods of Qionghua and control methods of diseases and insect pests.

Qionghua grafting method

1. Material selection

This step is very important because it is related to the flowering time after grafting. If it is a seedling, then it can blossom in seven or eight years, so the waiting time is too long. However, if you choose adult branches with buds, then once you survive, you can blossom in a good year. Therefore, the selection of the mother's branch that can bloom is usually relative to the periphery above the crown.

two。 Soil selection

Although this plant is relatively adaptable, it can grow ordinary soil. However, the roots of plants planted in sand will be more developed, so we should choose this kind of soil.

3. Time selection

Under normal circumstances, we will choose early March, because this stage is the time for budding, when the temperature is more appropriate, neither cold nor hot.

4. Concrete steps

Cut a length of about 5 cm from the selected branch, preferably using a terminal bud and grafting using a "high connection" method. When finished, put it in a shadow environment or take appropriate shadow measures. When the leaves grow out, they can receive the sun.

5, points for attention

Because of the growth correlation between the main branch and the branch of the plant, we should cut off the top of the main branch after the lateral branch is grafted. This can accelerate the growth of scions and enter the flowering stage more quickly.

Qionghua flowering time

When will Qionghua blossom? In fact, Qionghua is in April every year; when it blossoms in May, the flower can last about 20 days.

Pest control methods of Qionghua

1. Growing season

Although Qionghua is not picky about the growth environment, it does not mean that its growth rate is always on the same line. Like all flowers, Qionghua can only grow rapidly at a certain time, but we are very happy. When it grows, we must not forget that at this time, diseases and insect pests are actually the most dangerous creatures. If we often use fertilizer, the amount of fertilizer applied each time is very small, when the leaves are still yellow, we should understand the causes of diseases and insect pests that make the leaves unnutritious.

At this point, we should take measures to treat diseases and insect pests. Generally speaking, we will choose the solution of ferrous sulfate. If you spray this solution on the leaves, it will effectively kill the abominable pests, but you must pay attention to the proportion of the solution. If too much or too little is not good, then we must see that we need to use 1/1000 of the solution.

2, rainy season

In fact, Qionghua itself was very vulnerable to insects at that time. This is because its very good characteristic is that its leaves actually have a lot of fur, so pests will not hurt their roots, but despite its strong defense function, its epidermis is its weakness, and the degree of keratinization here is not high. Some pests take advantage of this feature, they can secrete certain substances, and these substances happen to be this thin layer of keratin can dissolve. This provides a considerable possibility for the invasion of pests and diseases.

This usually happens in the rainy season, so we should pay attention to the rainy season and we must take effective measures to protect Qionghua. Our measure is usually to spray pesticides, which are commonly used pesticides, so they don't have to worry about buying them. Its name is Bordeaux.
