When to plant Silene conoidea? Detailed guide to planting time and methods
Silene conoidea is an annual herbaceous plant that can be eaten as a wild vegetable. In some regions it is called maihuangcai, lantern grass, wild spinach or rabbit head, and it is a wild vegetable loved by many people. And now we all know that wild vegetables are actually more popular than cultivated vegetables, and growing Silene conoidea is also a trend in market development. So when is Silene conoidea generally planted? And how should it be grown? Let's take a look together below.
1. Sowing time
The planting industry is developing rapidly now, and planting techniques are constantly being improved. If greenhouse cultivation techniques are used, it can basically be grown all year round. But if it is grown in open fields, it is generally in March and April each spring and September and October in autumn. The planting time is related to the planting region as well as climate, temperature and various other factors. As for the specific planting time, it can be decided according to the temperature at which the local soil warms up.
2. Land preparation
⟦NL>Wild vegetables all have relatively strong vitality and do not have high demands for soil, so Silene conoidea can generally be planted in ordinary soil. However, it is even better if there is a relatively abundant water source near the planting site, or if drainage and irrigation are relatively convenient. Land preparation generally requires deep plowing of 30 to 40 cm, then breaking up the clods of soil as finely as possible, and finally spreading sufficient farmyard manure and raking the land level. Water ditches should be made well in the field to facilitate later field operations.
3. Sowing methods
There are two most commonly used sowing methods for Silene conoidea, namely broadcast sowing and drilling. For broadcast sowing, the land needs to be watered wet first, then the seeds are evenly scattered on the soil. A stick or broom can be used to gently press the seeds into the soil, and finally a layer of rice straw is covered for insulation. If the seeds are not pressed in, then fine soil must be used to cover the seeds, and rice straw also needs to be covered. For drilling, small furrows need to be made one by one, the small furrows watered thoroughly, then the seeds evenly scattered in, covered with soil, and plastic film put on for insulation.
4. Temperature control
Temperature management after sowing is very important. It affects whether Silene conoidea can emerge and how it grows. After sowing, the field temperature should generally be kept at around 15 to 20 degrees, and about one week before emergence, the temperature of the planting site should generally be between 20 and 25 degrees. Such temperatures can let the seeds of Silene conoidea sprout and grow quickly. When about 75 percent of the seeds have emerged, the rice straw or film covering the field should be removed promptly to avoid burning the seedlings.
5. Scientific management
Later fertilizer and water management, weeding and pest control directly affect the yield and quality of Silene conoidea. Before emergence, we should spray water to keep the soil moist, so as to avoid soil crusting and affecting seedling growth. When most of the seedlings have sprouted tips, we need to spray foliar fertilizer to promote the growth of the sprouts and achieve the effect of uniform and strong seedlings. When Silene conoidea has grown three to four true leaves, carry out reasonable thinning. After thinning comes the period of vigorous growth for Silene conoidea, when the water demand is very large, so watering should be done scientifically and combined with weeding and fertilizing to promote rapid seedling growth. The most common diseases and pests of Silene conoidea are downy mildew, aphids and cabbage caterpillars, which can respectively be treated and killed with metalaxyl wettable powder, imidacloprid wettable powder and dimethoate emulsifiable concentrate.
The above is all the content that the editor wants to share with everyone today. It mainly discusses the planting time and planting methods of Silene conoidea. If there are friends who want to grow Silene conoidea, through the above text you can roughly understand how to grow Silene conoidea, and I also hope it can help more friends in need.
