Yuzhu seeds are suitable for autumn sowing. The collected seeds can be used for sowing after germination treatment.
October is a good time for sowing, not only because the newly collected seeds have not been stored and will not be damaged, but also because October has relatively good temperature and light conditions, which is conducive to seed germination.
If it is not suitable to plant in autumn, the time of planting can be adjusted to about March next spring. This involves the storage of seeds.
The seeds of Yuzhu can be stored in sand. Mix the seeds with wet sand and put them in a dark place. Pay special attention to the temperature control, 0 ℃ ~ 5 ℃.
If the temperature is too high, it will cause seeds to germinate or rot. if the temperature is too low, it will cause seeds to be frostbitten, which will affect the germination rate of seeds after sowing.
Planting Yuzhu land is very important, which is not only related to the germination rate, but also related to the quality of the plant.
The choice of land depends on the texture of the cultivated soil. It is better to choose sandy loam which can drain water in time as its planting land. It is also necessary to ensure that the selected soil has a certain ventilation capacity for the normal germination of seeds. In addition, we should pay attention to the pH value of the soil. It is better to be slightly lower than 7, which is more suitable for its growth.
Land selection also depends on the geographical location of the land, to ensure that it can receive sufficient light without affecting the normal growth of the plant because of the strong sunlight.
Before the seeds are put into the soil, it is necessary to turn the soil deeply once to ensure that it is more than 30cm and bring enough air to the soil. When turning over the soil, you should pick out the big stones in the soil, so as not to affect the germination of seeds.
In addition, some basic fertilizer should be applied to the soil, and the amount of application can be determined by the number of specific planting
Finally, we need to level the soil surface, and then adjust it into a high border of about 13cm.
Before sowing, dig a ditch horizontally on the border every 10 cm or so, with a depth of about 3 cm.
Then evenly spread the seeds in the ditch, not too compact, about 10-12g dry seeds per square meter. Then cover the seeds with soil until they are flush with the border. Then cover the soil with a layer of grass or leaves to keep warm and moisture.
