Preface:
The timing and method of seeding is crucial if we want to grow the small aroma. Many of the newcomers spread out and ended up without seeds or even particles. When will the seed plant take root? How do you treat the soil to keep it alive


Basic analysis of the aroma
The aroma is an umbrella aroma of one or two years of herbivorous plants with a straight tubing height of 60-80 cm. The whole fragrance of the fragrance is derived mainly from volatile oil components in plants。

The aroma is not only available as a spice, but also has important medicinal and health value. The aroma contains a wealth of active substances, such as aroma brain and adehyde, which have the effect of ventilating and spreading the cold in the air。

From a nutritional point of view, the aroma is rich in proteins, vitamins and minerals. Per 100 grams of fresh aroma contains 3. 3 g of protein, 4. 2 g of carbohydrates, vitamin c 38 mg, carrot 2. 1 mg and various mineral elements such as potassium, calcium and iron。
These nutrients not only provide the unique fragrance but also provide the necessary nutrients for the human body。


The timing of planting is precisely controlled
The growth and development of the aroma has strict temperature requirements. The most appropriate growth temperature is between 15 and 25 °c, with a marked decrease in growth over 30 °c and almost stagnation below 5 °c。
On the basis of this characteristic, spring and autumn are the best periods for the field to plant aroma。

Spring cultivation should be chosen to start at temperatures above 10°c, usually around the spring. Temperatures are gradually rising during this period, the soil is unfrozen and fully hydrated, and it is well suited to the growth of the aroma seeds and seedlings。

Autumn planting should take place after the summer heat has receded, usually before and after the fall, at a time when the temperature is gradually decreasing, but the temperature is still high, contributing to the rapid growth of seeds。

Seed treatment technology details
Treatment of thorium seeds is a key component of successful planting. The aroma seeds are in a double-suspension structure, each containing two seeds. Commodity seeds are usually treated separately, but seed treatment requires special attention。

Inadequate seed handling has a direct impact on the growth rate and the quality of seedlings。
Seed treatment begins with the clean selection and removal of impurities, pest fruit and empty particles. Selected seeds are to be separated and dichotomy is to be separated by light hand or professional separation equipment。

Separated seeds also require drying or drying to reduce their water content to less than 13 per cent, which will facilitate both seed storage and gerontization。


Points for soil selection and improvement
The requirements of the aroma for soil are more stringent. The ideal planting soil should be loose, air-transmitting sandy soil. Soil ph is appropriate for 6. 5-7. 5 and organic content is required to exceed 2 per cent。
If soil conditions are not ideal, improvements are needed to create suitable growth environments。

For adhesive soils, the soil structure can be improved by adding materials such as river sand and decomposition. Each acre of land can be added 2,000 - 3,000 kg of sand, fully mixed with the topsoil。
At the same time, the application of 1500-2000 kg of decomposition organic fertilizer will not only improve soil structure but also provide sufficient nutrients。


Scientific fertilizer management system
Fertilizer management of the aroma should be based on the principle of "basic, supported by fat". It is based on organic fertilizer, which is applied to mature farmers by 2000-2500 kg per acre, combined with 100 kg of compound fertilizer. The base fats should be thrown deep into the soil during the process to ensure that the fertilizer is fully mixed with the soil。

The pursuit of fat during growth is determined by the growth of the aroma and soil fertility. The first fat chase is usually carried out with urea per acre up to 15-20 cm。
The second follow-up was carried out after the first harvest, mainly to supplement fast-activated nitrogen fertilizer and promote rapid regenerative growth。


Water management fine-tuning policy
The aroma is a drought-resistant crop, and the key to water management is to keep the soil wet without water. The soil content at seeding is 60-70 per cent suitable for wet or dry seeding. During growth, irrigation levels are adjusted in a timely manner in accordance with weather conditions and soil conditions。

The irrigation method recommends the use of glitter or drip irrigation to avoid flooding. Each recharge should be carried out in a light and hard manner, generally in a dry and wet state on the surface of the soil。
The soil moisture should be maintained at 70-80 per cent of the water held in the field during the booming season of the aroma so as to meet the growth needs of the plant without causing oxygen deficiency at the root。

Concluding remarks:
The aroma cultivation is a more technical and economic agricultural activity. Through scientific cultivation management, not only can significant economic benefits be achieved, but it can also provide markets with quality agricultural products. In practice, care should be taken to apply planting techniques in a flexible manner, adapted to local climatic conditions and soil characteristics, in order to achieve high quality production of aroma。
