Matters needing attention in spinach planting

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

1. Time

Spinach was a vegetable with obvious seasonality in the previous planting, but with the progress of planting technology and the development of varieties, it could basically be planted in four seasons, but it was best to sow in mid-March in spring, and the temperature change in summer was obvious. It was better to sow in batches, so the yield would be higher. Therefore, the first batch was sown in early May, the second batch was sown at the end of June, and the third batch was sown in early July. Autumn can be sown throughout the season, winter can only be sown in November, otherwise it will be frozen to death, so every season has the most suitable time for planting, must grasp well oh.

2. Seed selection

Now spinach varieties are very many, each variety has different resistance, so it also determines what kind of varieties are better to plant in what kind of season, such as planting in summer six need to choose varieties with high temperature resistance and drought resistance, while winter needs to choose varieties with strong cold resistance, autumn is generally the peak period of disease, so it is necessary to choose strong disease resistance, and spring rainfall is sufficient, then it is necessary to choose varieties with strong flood resistance. The second is to look at the climate change and temperature change of their own location to select seeds.

3. Germination

Spinach is a very magical thing, it does not need to germinate when sowing in spring, because it will sprout soon as it is sown, but once it reaches summer and autumn, it must germinate quickly, so as to shorten the growth period, which can reduce diseases to a certain extent. We usually soak the seeds in clean water for about one day, or put them in the refrigerator for one day, and then take them out and put them at room temperature for germination. Under normal circumstances, it will germinate completely in four or five days, which can improve the emergence rate and shorten the growth cycle, which is very helpful.

4. Temperature

The temperature suitable for spinach growth is preferably about fifteen to twenty-five degrees Celsius. Under this condition, spinach grows faster than usual and has no diseases and insect pests. Although we are only able to grow spinach in four seasons, it means that spinach can grow at any temperature. However, when the temperature is lower than five degrees Celsius and higher than thirty degrees Celsius, the yield and quality of spinach are not high. If there is no artificial careful maintenance at that temperature, Well, the spinach planted is relatively thin and has no moisture. Of course, we can also manually regulate the temperature, such as physical cooling or ecological cooling.

5. Nutrients

The quality of spinach is largely related to the fertility of the soil. The correct way to fertilize is to slowly increase the amount of fertilizer and the concentration of fertilizer each time. This is the best way to grow spinach. Since spinach is a leaf-eating vegetable, we mainly promote the growth of spinach. The most commonly used fertilizer is urea, or fecal urine. The spinach irrigated in this way is tender and strong. It looks very fresh and appetizing.
