1, solarization is an economical and useful way to kill germs and avoid the transmission of germs to the plant, but also can be useful to improve the germination rate and enhance the germination potential of asparagus seeds. Before plowing, pick a sunny day to put the seeds on the cloth bag, thickness 1-2 cm, sun exposure for 2-3 days, before dipping the seeds can also be used in other ways to disinfect.
2, asparagus seed skin thick and sturdy, there is a layer of wax on the outside, so it is difficult to absorb water, and it must be immersed in seed germination before plowing.
3, cleaning treatment will be placed in the seeds in the water, fish out the poor quality seeds on the water surface, and then soak in 40 ℃ ~ 50 ℃ warm water, with the hand repeatedly gently rubbing the appearance of the seeds, so that the color of the seeds on the outside of the grey, presenting small grooves, marking the wax of the seed skin has been broken, and then change the warm water for soaking, general soaking 2-3 days, sooner or later, each time to change the 25 ℃ ~ 30 ℃ of warm water.
4, seed disinfection disease is the main factor affecting the growth and development of asparagus, the seed is the center of the disease carriers, in order to prevent the onset of disease, before sowing, we should use fungicides to deal with seeds. Generally use 50% carbendazim wettable powder 10 grams plus 2.5 liters of water, soak the seeds 1 kg, soak for 24 hours.
5, germination germination is an important way to progress the germination rate of seeds and shorten the seedling time. The way is to have soaked seeds out, put people in a tile pot, covered with a wet cloth, placed in a warm box at about 25 ℃.
6, in order to avoid smothering the seeds, every day, late morning and early evening water to clean 1 time, after 2-3 days the seeds can show white. When the seeds have about 10% white can be plowed. If more whitening, early whitening of the radicle will grow too long, plowing is simple to bruise damaged, affecting the seedling rate.
