Causes of excessive growth of cotton and its control
The phenomenon of excessive growth of vegetative organs such as stems, branches and leaves of cotton plants, which makes vegetative growth and reproductive growth out of balance, is called overgrowth, commonly known as "crazy growth". The vegetative growth and reproductive growth of cotton are carried out synchronously after budding. If the vegetative growth is too fast and the reproductive growth is inhibited, it will cause bud and boll shedding, and in serious cases, there will be no boll formation. The reason for overgrowth: mainly due to the application of too much fertilizer and water. The period from budding to the early stage of flowering is the fastest vegetative growth period in cotton life. If the supply of nitrogen fertilizer is too much, it will result in the proportion of carbon and nitrogen metabolism.

Control techniques of overgrowth of Cotton
At present, cotton has entered the budding stage, the prevention and control of cotton overgrowth must start from now on. The so-called overgrowth means that cotton loses the function of normal growth, that is, it only blossoms but does not bear peaches, or blossoms more than peaches. First of all, the reason is caused by climate factors, the second is the blind introduction of cotton varieties, and the second is that the cultivation means do not adapt to climate change. According to records, when the temperature exceeds 35 ℃, the pollen development is abnormal and can not pollinate normally, while the persistent drought aggravates the shedding of buds and bolls. In addition, some cotton areas appeared in the middle of August.

Propagation management of oleander
The propagation method of oleander can be propagated by cutting, ramet and striping, among which cutting is the most commonly used propagation method. Cutting can be carried out in both spring and summer. If the cuttings were soaked in clean water for 7 ~ 10 days before cutting and kept fresh, they could take root ahead of time and the survival rate would be improved. The specific method is that the 1-to 2-year-old branches cut in spring are cut into stem segments of 15 cm ~ 20 cm, 20 or so are tied up in a bundle, soaked in clean water, and the water depth is 1 ℃ 3 of that of the stem segment. The water at the same temperature is changed once every 2 days, and the temperature is controlled at 20 cm ~

What are the symptoms, causes and characteristics of oleander witches 'broom disease? How to prevent?
The arbuscular pathogen of oleander mainly damaged the branches of oleander. The disease occurred on individual branches at the beginning, showing a large number of axillary buds and adventitious buds sprouting, clusters of many thin and weak branches, stagnation of main shoot growth, shortened internodes of branches, smaller leaves, and inconspicuous mosaic. Infected branchlets can also take out branchlets, new branchlets base swelling, light red, often clustered into a group, branchlets increasingly thin, leaves are getting smaller, appearance like a nest, forming typical arbuscular symptoms. Victim branchlets are mostly erect, branches have tubercles. Cortices decayed, stripped, ulcerated,

Cutting technique of oleander in spring
Oleander has long leaves like bamboo, flowers like peaches, and a long flowering period, which can last from mid-April to mid-September. Blooming flowers, thick green branches and leaves, proud frost fighting snow in winter, has a high ornamental value, is an excellent green tree species. At the same time, it has strong resistance to sulfur dioxide, so it is also an ideal plant for factory greening. The propagation of oleander is relatively easy, and it can be propagated by means of pressing, tillering, cutting and so on. The number of female plants is limited by striping and tillering, so it is not easy to propagate in large quantities. Use spring field cuttings

Plant gold-- Taxus chinensis
Taxus is a species left over from the Quaternary glacier, known as the "living fossil" of the plant kingdom, is a rare and endangered plant in the world, and it is listed as a first-class protected plant in China. When the yew fruit is ripe, the red fruit is full of branches and colorful, which is named because it is very similar to the "Acacia bean" in the south. It is not only an important timber tree species, ornamental tree species, but also a precious medicinal plant. In 1989, the United States took the lead in the detection of paclitaxel from the substances contained in Taxus. Experiments have shown that paclitaxel has a unique anti-tumor mechanism and significant anti-tumor effect, and is considered to be the most effective.
