Timing of cultivation
Cultivation times are usually in the spring of each year, when the environmental climate is more suitable for seed growth and is generally grown by seedlings. In the case of warm areas of the south, sowing can be done every spring, february and march, and in the case of the north, it will have to wait until after april until the ambient temperature stabilizes. Seeding is also possible at the summer fall festival, and the best planting time is in spring。
Soil selection
Before planting, it needs to be given a choice of fertile and flat plots, preferably sandy soils, with enough bottom fat on the plots, with a higher demand for fertilizers, which can be applied more appropriately when applying, and a higher resistance to fertilizer, which is less likely to be fertile, followed by a tilling process that combines both fertilizer and soil. There is also a need for good irrigation and drainage systems on the plots, so that the amount of water in the fields can be better understood, both during the dry and heavy rains。
Three, dig the ditch
In preparation for seed breeding, seeding needs to be spread at a distance of about half a metre, followed by stripping, with a depth of 1. 5-3 centimetres to dig the ditch, and once seeding is completed, cover a layer of soil of 1-3 centimetres and then water the base。
Iv. Last containment
After the planting has been completed, the matrix needs to be kept in a micro-humid state, and when the seedlings grow to about 3 cm, care needs to be taken whether weeds appear in the field. When the plant grows to 6-9 cm, the seedlings begin, the small seedlings that are weak and in poor condition are uprooted, and the spacing of the plant is 12-15 cm。
