怎样浸泡辣椒种子

How to soak pepper seeds

1.播种前5天,用温度为52~55℃的水净泡种子,置于室温下8~12小时。

Five days before sowing, the seeds were soaked in water at 52 ℃ ~ 55 ℃ for 8 ~ 12 hours at room temperature.

2.将种子从水中捞出,用湿纱布包好,沥干水分置于恒温箱、热炕或暖气片上部(暖气片上应垫木板,以免烫坏种子)催芽,温度尽量维持在28~30℃,不得过高。

Remove the seeds from the water, wrap them with wet yarn cloth, and put the drained water in the incubator, hot Kang or upper part of the radiator (the heating plate should be padded with wood to avoid damaging the seeds) to accelerate the bud. The temperature shall be kept at 28 ℃ ~30 ℃ as far as possible, and it shall not be too high.

在这期间应经常翻种子 ,以力透气,在水分不足时应淘洗种子。当有80%的种子露白时,即可播种。

During this period, the seeds should be often turned over for ventilation. When the water is insufficient, the seeds should be washed. When 80% of the seeds are white, they can be sown.

1)要用科学方法管理辣椒。

We should use scientific methods to manage pepper.

2)要做好观察记录。

Observation records should be made.

4.待辣椒成熟后,交流我们的收获。

When the pepper is ripe, we will share our harvest.

1)种辣椒不是想象的那么简单。

Growing pepper is not as easy as you think.

2)这是我收获的辣椒

This is the pepper I harvested

5.将自己种植的种植的辣椒取出种子,在进行种植,看能不能长出新的辣椒。

Take out the seeds of your own pepper and plant them to see if they can grow new pepper.
