What are the cultivation methods for Northeast asparagus bean?
Asparagus bean is mainly grown for the tender tips of its vines, and this vegetable is loved by many households. Many people grow one or two plants on their balconies, which both beautifies the environment and provides food. So what are the cultivation methods for Northeast asparagus bean?
1. Seed selection: There are actually quite a few varieties of asparagus bean, such as the tender tips of chayote, the seedlings of peas, the tender tips of asparagus, and so on. The asparagus bean most commonly seen on the market today is the tender tips of asparagus and the tender tips of chayote, because it can be harvested multiple times without affecting the yield of its original product, especially chayote. However, asparagus bean takes different forms in different regions, and the key is to see what that region is better suited to growing. For example, in the Hunan region, peas are better suited to cultivation, so peas can be grown as asparagus bean.
2. Sowing: There are two ways to sow asparagus bean. One is to make small furrows one by one in the prepared land, with a furrow depth of about three to four cm, then evenly scatter the asparagus bean seeds into the prepared furrows, finally cover the seeds with one to two cm of thin soil, then water each furrow once and cover it with a layer of plastic film, or pile on a layer of rice straw or dry grass compost, all of which are fine. This can speed up emergence. The second sowing method is relatively simple: water the land to be planted once to make sure all the soil is irrigated, then evenly scatter the asparagus bean seeds, finally use a tool to bury the seeds into the soil, or cover them with a layer of fine soil, and then cover with a layer of dry grass.
3. Fertilizing: For asparagus bean, we eat the tender tips of the plant, so our goal is to make the stems and branches of the vegetable grow more, so that the yield of asparagus bean will be higher. Generally, during the growth of asparagus bean, we need to fertilize continuously. Usually, after each harvest, one fertilization is needed to promote its growth rate and shorten the time until the second harvest. The fertilizers usually used are mainly urea and biogas slurry water, which can make the seedlings grow faster. At the same time, in routine management, we can remove the main growing point of the vine to promote the growth of side branches, which can greatly increase the yield.
4. Pest and disease control: Asparagus bean can be said to have no diseases, and only occasionally some pests appear, such as aphids, cabbage worms, moth pests and leaf rollers, etc. They mainly harm the leaves and stems of asparagus bean, which lowers the quality of asparagus bean and, in severe cases, causes the plant to wither and die. For routine daily control, manual capture and traps can be used for trapping and killing, and when necessary, chemical control can be used. The most commonly used agents are chlorothalonil solution, trichlorfon and Bordeaux mixture. Note that no chemical spraying should be carried out within half a month before harvest.
Growing Northeast asparagus bean is relatively simple, and its growth rate is also very fast. Generally, it can be harvested once every four to five days, enough to stir-fry a plate of fresh and tasty green vegetables.
