The planting method and planting time of Huo Xiang

When planting Huoxiang, it is best to choose loam or sandy loam in fertility, control the temperature at 18-25 degrees, properly apply some nitrogen, phosphorus and potassium fertilizer, control the amount of water, and take good drainage measures. and timely removal of weeds in the garden can grow healthily. When planting, it is best to plant from the end of March to early April in spring or from September to October in autumn, and sow seeds in shallow trenches as far as possible.

When planting Huoxiang, we should also pay attention to the following points:

1. Temperature: Huoxiang has the characteristics of high temperature and light. Generally, the annual average temperature of planting Huoxiang should reach about 1926 degrees. The temperature suitable for the growth of Huoxiang is 15-25 degrees Celsius, and the temperature of the planting site should be kept between 20-25 degrees at the time of emergence. The temperature of later growth should not be lower than 16 degrees and not higher than 35 degrees, otherwise it will affect the growth rate and even cause Huoxiang to stop growing.

2. Water and fertilizer management: Huoxiang generally has the best effect of whole fertilizer, that is to say, it should be fully applied each time, including nitrogen fertilizer, potassium fertilizer, phosphate fertilizer, organic fertilizer, farm fertilizer and so on. Secondly, it is necessary to combine watering and ploughing when fertilizing, which is conducive to the absorption of nutrients, while maintaining the moisture of the soil and maintaining the water supply needed for the normal storage of plants. Finally, we should pay attention to timely drainage when there is more rainfall to prevent flood hazards.

3. Plant density: if sowing in spring, the sowing rate per mu is generally 500 to 800 grams, while sowing in autumn is 500 grams to 600 grams per mu. From the above sowing rate, we can see that the density of sowing in autumn will be higher than that in spring. The row spacing of spring sowing is generally between 25~30cm, while that of autumn sowing is generally between 30~35cm.

4. Pest control: it is a point that needs to be paid attention to in the process of planting. The main diseases of Huoxiang are Fusarium wilt, corner spot, brown spot and spot blight. We can use carbendazim, Bordeaux solution, Metalaxyl manganese zinc and Rhizoctonia. And the biggest harm is red spider, silver leaf moth, leaf borer, ground tiger, mole cricket and so on. In general, mites are used to kill trichlorfon.
