Nowadays people pay great attention to diet. People who are used to eating big fish and meat are now popular with “wild vegetablesâ€. Therefore, many wild vegetables in the countryside have become frequent visitors on the table. Among many wild vegetables, the toon is most popular. Citron is also known as "tree vegetables", which is rich in nutrients and high in food value. Let's take a look at its cultivation management techniques.
Cultivation and management techniques of camphor
1, seed selection
The cultivation of the camphor, the seedling method is seed reproduction, which has a great influence on the yield and quality of the camphor. The ripening time of the seeds of Toona sinensis is from October to November, and when the capsules are changed from green to reddish brown, they can be collected. The age of the selected fruit is preferably 15 to 30 years, which can effectively ensure the fullness of the seed and increase the germination rate in the later stage.
2, seed treatment
The seed coat of the toona sinensis is hard, and the water absorption ability is poor when it is broadcasted, and the germination is troublesome. The seed can be soaked before sowing. Method: Soak it in warm water of about 25~30 °C for 24 hours (one day and night). After the seeds are removed, the water can be controlled to spread effectively at room temperature and covered with a towel. The germination time is usually about one week, and water is poured once a day to increase the sprouting rate.
3, sowing
When the seed buds grow to 1 to 2 mm, they can be sown. The choice of sowing time should be appropriate, not too early or too late. If it is too early, the low temperature is not conducive to the growth of seedlings, causing the toon to suffer from night cream. But too late will shorten the growth period of the seedlings. The sowing time is from the end of March to the beginning of April, and the lowest temperature can be sown at 1~5 °C. The sowing soil is preferably loose and fertile sandy loam as a seedbed, and 50 kg of calcium phosphate is applied per mu. After cultivating the soil, the germination seeds can be evenly spread, and the seeds can be mixed with 15-20 times of sand, and the soil is covered after sowing. 1~1.5 cm can be.
4, post-production management
Weeding in time after sowing, keeping the soil temperature (controlled at 20-23 ° C during the day, 12 to 15 ° C at night) and humidity, about 7 to 10 days to emerge. After the emergence of the camphor, the fertilizer and water management should be done according to the drought conditions and the growth of the seedlings to promote the growth of the seedlings.
5, transplanting seedlings
As the seedlings grow, when the seedlings grow to 2 to 3 leaves, the seedlings are once, and 4-5 leaves are fixed. Be careful not to hurt the roots when the seedlings are harvested. The seedlings are fixed according to the plant spacing of 20 cm and the row spacing of 25~30 cm. The seedlings are timely watered and fertilized.
In the process of seedling growth, we must pay attention to cultivating loose soil and promote the growth of seedlings. When the camphor seedling grows to 50~100cm, it can be sprayed once with 15% paclobutrazol WP 1500 times, which can accelerate the lignification of seedlings, increase plant branching trees, enhance cold resistance and ensure winter safety.
The above is the cultivation and management of the camphor. The wild vegetables have high nutritional value and high edible value. Modern people like to eat. If there are conditions, you can try it, and the prospects are still very impressive. For planting points, please refer to the above.

Cosmetics are compound mixtures made of various raw materials through reasonable deployment and processing. Cosmetics have a wide variety of raw materials with different properties. According to the raw material properties and uses of cosmetics, it can be roughly divided into two categories: matrix raw materials and auxiliary raw materials.
The former is a kind of main raw material of cosmetics, which occupies a large proportion in cosmetic formulations and plays a major functional role in cosmetics. The latter is responsible for shaping, stabilizing or imparting color, fragrance and other properties to cosmetics, which are not used in cosmetic formulations, but are extremely important. Cosmetics are chemical mixtures made of natural, synthetic or extracted substances with different functions as raw materials and processed through production procedures such as heating, stirring and emulsification.
