Asparagus is a famous lazy crop cultivation is very simple, because there is no special requirements for soil moisture temperature and other aspects. Regular consumption of asparagus has a good effect on the prevention of cancer. Secondly, although asparagus is good to grow, it is still rare in the Chinese market, so the price is more expensive than ordinary vegetables, usually ten dollars a pound. Since it's not very productive, what should I pay attention to when growing asparagus?
Germination method, we need to soak asparagus seeds in warm water before sowing, a little longer than other seeds. Usually need to soak for seven or eight days, then fish out the seeds and soak them in formalin solution for six hours, then wrap them in cotton cloth and rinse them with water. Finally, the seeds are wrapped and placed at 30°C to germinate. Usually after three days, eighty percent of asparagus seeds will grow sprout white, and then we can sow.
Reasonable ground preparation, before sowing, we need to make the ground ten days in advance. In order to realize the high yield of asparagus, we usually choose a plot of land close to the water source, and at the same time to be relatively flat, try not to have depressions. If this is the case, the depressions need to be filled in, using an excavator if necessary. Next, it is best to plant in loose, sandy soil, which is more permeable.
Planting density, although in the case of planting density is very small can also produce asparagus, but if you compare carefully, you will find that the higher the density of asparagus will grow better and more vigorous than the low density of asparagus, so don't think that the more planted in an acre of the higher the yield, the most important thing is to reasonable planting density. Generally speaking, the optimal planting density is 25-35 centimeters per plant and 100-150 centimeters per row.
Scientific fertilization, in order to get high yield, fertilization is also special. Generally we need to open a ditch when applying basal fertilizer, and this ditch is not the same as the previous ditch. Generally need to dig about 50 cm, and then the livestock manure poured into the ditch, pile a layer of soil, planting time need to first water the place where the base fertilizer is applied. In addition to the base fertilizer, asparagus is also fertilized three times. The first time, when it breaks through the ground, it uses mainly human feces. The second time, it uses human feces with a little urea ten days before harvest. Finally, after harvest, it is sprinkled with some organic rotting fertilizer, urea, phosphorus fertilizer and potash for maintenance, so that it can grow a second time without reducing the yield.
Effective prevention of disease, the main disease of asparagus belongs to stem blight. The main control method is to clean up the planting site, use ditches for drainage, till and loosen the soil, apply less or no nitrogen fertilizer, and apply more potash fertilizer, so that the plant grows healthily and strengthens its resistance. Secondly, spray Bordeaux solution or 50% carbendazim 800 ~ 1000 times and spray insecticide to control pests. And spray every 15 days or so.
Summary; asparagus has high price, high demand and good planting prospect. There are few farmers in China who grow asparagus, but it is not easy to grow asparagus well. I hope that after studying the asparagus planting conditions and methods in this article and the management skills after planting, combined with their own actual situation and flexible use, planting high-quality and high-yield asparagus, to get a high return.
