Morphological characteristics of Angelica sinensis
Angelica sinensis is a perennial herb with a height of 0.4 million meters. Root fleshy, conical. After cultivation, most of the branches. After planting in the second year, the stem is erect, 1-1.2 meters high, light purple (a few are light comprehensive color). The leaves are 2-3-pinnately compound, and the base of the petiole is sheathlike clasping. Terminal compound umbel, florets white. The fruit is oval and double hanging, and the two petals are dehiscent after maturity. The flowering period is from June to July and the fruiting period is from August to September.

Swiss research uses mushrooms to improve wood properties
Switzerland's Federal Laboratory for Materials Testing and Research said Tuesday it is experimenting with mushrooms to improve certain properties of fir and spruce trees in order to expand the use of these woods. Fir and spruce, which account for 60% of Swiss trees, have the advantages of mechanical endurance and ease of processing, but also have weaknesses such as difficulty in fine processing and difficulty in long-term use. In addition, protective coatings such as fire, anti-corrosion or anti-ultraviolet coatings are difficult to penetrate into these woods, thus limiting their development and utilization, such as for building exterior materials. Researchers experimented with wood-eating mushrooms to change

How to prevent mushroom wilt
The dead mushroom is the phenomenon that the small mushroom on the mushroom bed shrinks, yellowes and dies. The mushroom withered in pieces or in batches, which will seriously affect the yield. 1. The reason for the death of mushrooms: 1. The temperature at the end of autumn was too high (more than 23 ℃), and the temperature increased during the period of mushroom emergence in spring (the temperature was 21 ℃ for several consecutive days), resulting in the death of young mushroom seedlings due to lack of nutrition. 2. Due to poor ventilation, insufficient oxygen and high concentration of carbon dioxide in the mushroom room, the heat generated in the process of metabolism can not be released quickly, which will make the young mushroom seedlings due to insufficient oxygen supply or

How to control the specification of mushrooms
In the sale of Agaricus bisporus, purchasers have very strict requirements for fresh mushrooms (2cm in diameter), which directly affects the production efficiency of mushroom farmers. The technology of how to control the size of mushrooms is introduced as follows. First, the mushroom variety commonly used by the replacement strain is "As2796" strain, which is a large-grain hybrid. Its main advantages are wide adaptability, strong stress resistance, large size and high yield, which are suitable for fresh sale in the market, but relatively few meet the specifications of merchants. If there is an order contract, it should be in time.

How to control mushroom maggots
Maggot larvae that harm mushroom fruiting bodies and hyphae are collectively referred to as "maggots". There are 4 common species, namely, gnat, gall fly, dung fly and so on. Their larvae, maggots, are morphologically similar to the naked eye, while adults are only significantly different from flies. Maggots (larvae) eat the fruiting body, turning mushrooms into waste products, and some endanger the hyphae. Mushrooms eaten by fungus maggots

Extraction of crop growth agents from mushrooms in Japan
Noda Edible Fungi Co., Ltd. of Japan has developed a growth agent extracted from mushrooms that can promote crop growth, which contains four natural plant hormones and a new glycoprotein that promotes the growth of crop roots. The experimental results show that spraying this growth agent on leaves or stems can promote the growth rate of herbaceous crops by 6 to 8 times and woody crops by 2 to 4 times, and there is no drug residue. At present, the growth agent has been used in the rapid breeding of trees, flowers, vegetables and other crops.

How should geranium spot disease be prevented and treated?
Pelargonium spot disease control: a, small area planting, artificial removal of sick leaves, concentrated burning. 2. Improve the planting environment. Crop rotation shall be implemented in areas with serious disease, and planting density shall not be too dense to facilitate ventilation and light transmission, and accumulated water shall be removed in time. 3. During the disease period, spray 100 - 150 times of Bordeaux mixture or 500 times of 80% Diyindan wettable powder, or mix 50% thiophane methyl 1000 times and 80% Diyindan 500 times, or spray 45% chlorothalonil or polychlorothalonil.

Prevention and treatment of spot disease of pelargonium
The main symptoms are damaging leaves, primary waterlogged spots, and then round, 2-3 mm in diameter, slightly sunken in the center, with a small brown center and a spreading edge around the yellow. The old spot can be up to 6-10 mm in diameter and is irregular, dark brown, with concentric lines and less light black mildew layer due to the limitation of leaf veins. Disease spots on the leaves can converge with each other for a long time, often making the leaves black, wrinkled and withered. The condition of the disease mainly occurs in the older and weak tissue, so it is more common in the lower old lobe. Overcast and rainy

Make the geranium blossom more
1. Too much watering or rain, long-term stagnant water in the basin, causing rotten roots, yellow leaves or plant growth, all affect flowering. two。 Excessive fertilization, especially too much nitrogen fertilizer, is easy to cause branches and leaves to grow, no flowering or rare flowering, poor flower quality. However, insufficient or non-fertilization will also affect the normal growth and flowering of plants. Therefore, more phosphorus and potassium fertilizer should be applied in early spring or early autumn. 3. The temperature is too high or low. Winter room temperature is more than 20C, coupled with poor ventilation, branches and leaves are easy to grow, affecting the flowering of the following year.
