Cultivation method of gray vegetables

In fact, we do not know much about gray vegetables, so many people do not know that there are grey vegetables, which is a wild plant with strong adaptability to the environment and can be seen everywhere in rural areas. the main part of use is its new tender leaves, which have a unique taste, can also prevent anemia and promote growth and development, and play the effect of calcium supplement. So today, the editor will give you a brief introduction to the planting method of gray vegetables.

1. Soil preparation and fertilization

Due to the vitality of gray vegetable is very strong, it does not have great requirements for planting land, and it can even be planted with a small basin on the balcony of the home, but in order to make gray vegetables grow better, we can choose to plant in plots with fertile soil, convenient watering and deep soil layer under certain conditions, and we can do a little deep digging during soil preparation, but it is best to ensure the leveling of the land. Finally, farm manure can be applied evenly according to the average fertilizer requirement of about 5000 jin per mu.

2. Seed treatment

Grey vegetables grow and reproduce faster, so we usually use planting and sowing, but before planting, we need to make a simple treatment of planting, first of all, sift out the impurities in the seeds with fine sieving, then plant them in clean water, and fish out the seeds that float on the surface an hour later, and the seeds that sink to the bottom are relatively high-quality seeds, then we can prepare to sow.

3. Sowing method

There are two most commonly used methods for planting gray vegetables, namely, sowing and strip sowing. Sowing is to spread the seeds evenly on the whole soil, then irrigate the soil with water, and finally press the seeds into the soil to wait for seedlings. In the case of strip sowing, we need to make ditches about ten centimeters wide and five centimeters deep according to the distance between each row, and then spread the seeds evenly into the ditch. Then cover the seeds with a thin soil about three centimeters thick, and finally pour through the place where the seeds have been sown. Among them, strip sowing is more convenient for later field operation, so the editor suggests that it is appropriate to use strip sowing.

4. Field management

Seedlings will emerge about five or six days after sowing. Due to the strong resistance of gray vegetables, there are basically no diseases and insect pests. Secondly, under the condition of sufficient application of base fertilizer, there is generally no need for topdressing in the later stage. Only need to do a good job of water management and field weeding management. First of all, we need to check the seedlings in the field first, and then timely alkaline interseedlings and replenish seedlings, and then water the seedlings to ensure that they can survive, and the second is to weed about ten days after planting. At this time, we can adopt the way of mid-tillage, which can not only reduce the loss of nutrients but also promote the growth of gray vegetables, and if the leaves of gray vegetables are yellow, then it is the phenomenon of malnutrition. So the appropriate amount of topdressing micro-fertilizer, finally, pay attention to drainage and timely irrigation, as well as the late weeding is mainly artificial weeding.

5. Timely harvest

Grey vegetables can be harvested many times, and the first harvest can be carried out when the gray vegetables grow to about eight to ten centimeters, because if they continue to grow, they will be relatively old, and then the taste will not be very good. The second thing to pay attention to is that if the base fertilizer is fully applied, appropriate amount of urea will be needed for each harvest after the third harvest, but if the base fertilizer is insufficient. Then fertilization is needed after the first harvest, which can usually be harvested every half a month or so.
