Method of pre-sowing treatment of asparagus seed

Asparagus, also known as Yongcai, is a very popular vegetable in our country. With a wide range of planting area, the planting method of asparagus is generally based on seed planting. Before sowing, we should pay attention to the treatment of the seeds to improve the quality and germination rate of the seeds. So how to deal with the seeds of asparagus before sowing? The following editor will give you a brief introduction, let's have a look!

1. Seed selection

Before sowing, we should first select the seeds, mainly those with full seeds and suitable size. The seeds with dry, cut and damaged seed coat were selected to ensure the quality of the seeds and improve the germination rate. According to the planting method to control the sowing rate, if it is to raise seedlings, then the general amount of seeds per mu is about 50 jin, if it is directly sown in the field, then the amount of seeds should be controlled at about 10 jin / mu. After selecting the seeds, put them in a container, then put them in the microwave equipment and treat them over medium heat for about 15 seconds.

2. Soaking seeds

After microwave treatment, the asparagus seeds were directly soaked in clean water for about two hours. Then put the seeds into the seed soaking agent and soak the seeds for about half an hour. After soaking the seeds, take out and clean them. Seed soaking agents can be purchased on the market or prepared by themselves. Various substances such as chloropyruron, algin, citric acid and potassium nitrate are fully mixed with water. Then in the process of soaking seeds, we should pay attention to constantly stirring for at least 10 minutes. After soaking, wash it with clean water and soak it in the nutrient solution for two hours, and finally wash it again.

3. Accelerating budding

After doing a good job of soaking the seeds, the work of accelerating germination can be carried out. After soaking the seeds, wrap the seeds in wet gauze to squeeze out the excess water. Then refrigerate in an environment of about 5 degrees for about 11 hours. Then take it out and soak it in warm water of about 25 degrees for half an hour. Finally, remove it and put it in a thermostat for about 22 hours. If you want to observe the seeds frequently, when most of the seeds are white, you can start sowing.

4. Matters needing attention for budding

When the seeds sprout, we should pay attention to washing the seeds with clean water every day to keep the seeds moist so that the seeds can be heated evenly. After the germination work is over, we should spray some compound micro-fertilizer on the seeds. First of all, prepare about 4G of compound micro-fertilizer and 45g of water, mix them well, and then spray them evenly on the seeds. Finally, the seeds are evenly mixed with fine soil and sowed by traditional methods.
