The Latest Tutorial on Field Management Techniques and Methods for Asparagus Bean
Asparagus bean is a perennial wild famous vegetable with well-developed vines, which can be processed into agar and has high nutritional value. It can also be planted and sold for considerable economic value. So now it can also be propagated and planted artificially, and throughout the entire planting process you can find that planting is only one step, while management runs through the entire growth cycle, so the final quality and yield mostly depend on management.
1. Thinning and Weeding
After the seedlings emerge, weeds growing among the seedlings should be pulled out promptly before they grow large; whenever weeds appear, pull them out at any time. For thinning, thin once after the seedlings have all emerged, remove diseased and pest-damaged seedlings, and transplant weak seedlings separately or simply thin them out. Combined with weeding, you can loosen the soil between the rows with a small stick, which is beneficial for growth. When the seedlings grow to about 10 cm tall, the second thinning should begin. Seedlings with fast growth can first be transplanted into the field, leaving the others to continue growing. Each thinning must be carried out after watering to avoid damaging the roots.
2. Light Management
Seedlings need a certain amount of light, but because they are delicate themselves, outside light is too intense for the seedlings. So you can build an arched shed over the seedbed, and cover it with shade netting to block strong light and reduce sunlight exposure. This can prevent sunburn and water loss. The shade cover should remain until it is time for hardening off the seedlings, and only then can it be removed.
3. Fertilizer and Water
Asparagus bean has a weak root system, so its drought tolerance is weak, and it must maintain sufficient moisture to grow well. Therefore, after the seeds emerge, water every day to keep them moist. Then when they grow to 2 to 4 cm, begin applying some human and livestock manure, but it must be diluted with water and must have been disinfected and fully decomposed. The fertilization rate per mu is between 50 jin and 100 jin. Mainly apply nitrogen fertilizer, do not use chemical fertilizer at first, and you can add some superphosphate and potassium nitrate fertilizer. Then when they grow to 6 cm, carry out another topdressing, basically the same as the first application.
4. Planting Soil
The soil chosen at the beginning must be deep and fertile soil, but sometimes natural conditions are not sufficient, so the soil must be improved before planting. For example, dig out the gravel in the soil, improve the soil for planting, dig up some fertile soil, then add leaf compost and mix it together, and test a certain pH to make sure it is suitable before planting. When trace elements are lacking in the soil, foliar spraying of fertilizer should be done in time. When soil compaction occurs during the growing period, loosen the soil promptly to maintain good soil structure.
Generally, growing vegetables requires considering the management content above, but when growing asparagus bean, the specific management content we need to do is somewhat different, and certain adjustments need to be made according to the growth characteristics of asparagus bean. Only with this targeted management can management work be done well.
