The latest points for attention in spinach planting

Spinach is very rich in nutrients, and it is said to have anti-cancer effects. Spinach is a very popular seasonal vegetable at present. Spinach tastes slippery and tastes very good. The most important thing is that the cultivation of spinach is also very simple. It has a strong ability to adapt to the environment, so it has derived varieties that can adapt to various environments, and now the planting range of spinach is getting wider and wider. So today, the pro-agricultural network will take you to learn several problems that need to be paid attention to in the process of spinach planting. As long as you grasp these problems, the spinach planted will be strong and tender.

1. Time

Spinach was a kind of vegetable with obvious seasonality in previous planting, but later, with the progress of planting technology and the research and development of varieties, it is basically possible to plant in four seasons, but it is best to sow in mid-March in spring. the temperature change in summer is more obvious, so it is better to sow in batches, so the yield will be higher, so the first batch is sown in early May. The second batch was sown at the end of June and the third batch was sown at the beginning of July. And autumn is the whole season can be sown, winter can only be sown in November, otherwise it will be frozen to death, so every other season has the most suitable time for planting, you must grasp it.

2. Seed selection

At present, there are many varieties of spinach, and each variety has different resistance, so it determines which varieties are better to be planted in what season, such as planting six in summer, we need to choose varieties with strong resistance to high temperature and drought. In winter, we need to choose those with strong cold resistance. Autumn is generally the peak period of disease occurrence, so we need to choose those with strong disease resistance, while Rain Water is more abundant in spring. Then you need to choose the one with strong anti-waterlogging ability, and the second is to look at your local climate change and temperature change to select seeds.

3. Accelerating budding

Spinach is a very magical thing. It does not need to be germinated when sowing in spring, because it will soon emerge as long as it is sown, but once it is sown in summer and autumn, it must be germinated quickly and shorten the growth period. This can reduce diseases to a certain extent. We usually soak the seeds in clean water for a day or so, or refrigerate them for a day. Then take it out and put it at room temperature for sprouting, normally it will all sprout in four or five days, which can increase the emergence rate and shorten the growth cycle, which is very helpful.

4. Temperature

The best temperature for spinach growth is about 15 to 25 degrees Celsius. Under this condition, spinach grows faster than usual and does not have any diseases and insect pests. Although we can only grow spinach in the four seasons, it means that spinach can grow at any temperature, but the yield and quality of spinach are not high when the temperature is lower than 5 degrees and higher than 30 degrees. At that temperature, if there is no artificial careful maintenance, then the spinach planted is relatively thin and has little moisture, of course, we can also carry out artificial temperature control, such as physical cooling, or ecological cooling and other methods.

5. Nutrients

To a large extent, the quality of spinach is related to the fertility of the soil. The correct fertilization method is to slowly increase the amount and concentration of fertilizer each time. This is the best way for spinach to grow. Because spinach is a leafy vegetable, so we mainly promote the growth of spinach, then the most commonly used fertilizer is urea, or fecal water. The spinach watered in this way is tender and strong, so it looks very fresh and appetizing.
