A detailed explanation of the latest growing environment requirements for spinach cultivation
Spinach is one of the most popular vegetables in our country. Spinach is extremely high in nutritional value, and it has various effects such as stopping bleeding and quenching thirst, and promoting bowel movements. Its status among vegetables is relatively high, and growing spinach has also become a major vegetable cultivation project in our country. However, growing spinach still requires certain conditions, because spinach has certain requirements for its surrounding growing environment. So what kind of environment does growing spinach need? Let's take a look below!
1. Temperature
Spinach has very strong cold resistance, the strongest among all leafy vegetables. As long as the temperature after sowing is not lower than 4 degrees, it can germinate and emerge normally, but the most suitable temperature for seed germination is around 18 degrees. Its optimal growth temperature is also around 18 degrees. When the temperature exceeds 26 degrees, the growth of spinach will be limited and it cannot grow normally. The aboveground plants can develop normally at temperatures as low as around 6 degrees, so during the spinach cultivation process, the surrounding temperature must be strictly controlled so that the growth of spinach is in the most suitable environment, promoting growth and preventing problems caused by unsuitable temperatures.
2. Light
Spinach needs a relatively long period of light during its growth process, because flower bud differentiation is directly related to light duration and intensity. A long light duration and high intensity are beneficial to the flower bud differentiation of spinach and promote flowering, pollination and fertilization. Moreover, when promoting flower bud differentiation, not only must light be ensured, but it should also be kept at a low temperature as much as possible. After flower bud differentiation, increasing the temperature and maintaining the light duration can promote bolting and flowering in spinach. By increasing the pollination rate, the growth capacity of spinach becomes stronger and stronger, and the quality and yield will further increase.
3. Water
Spinach is a vegetable with a relatively large water requirement. This is because spinach has large leaves, is tender and full of water, and has many water-demanding organs. Therefore, during the cultivation process, sufficient water must be ensured in the field. Insufficient water will cause spinach plants to be short and weak, reducing yield, lowering quality, and making commercial value extremely low. If it is kept for a long time in a high-temperature, waterless environment, the growth of spinach will be inhibited, and the reproductive growth rate cannot be controlled, making spinach prone to premature bolting. During the cultivation process, the air humidity for spinach should be maintained at around 85%, and the soil humidity must not be lower than 70%.
4. Soil
Spinach does not have great requirements for soil. It can quickly adapt to various different soils and grow normally, but yield and quality will also differ to a certain extent. Therefore, if you want to grow high-yield and high-quality spinach, you should still choose soil with high fertility, looseness, and strong ability to retain fertilizer and water. Pay attention to the PH value of the soil. Slightly alkaline soil is beneficial to the growth of spinach, while soil that is too acidic will cause spinach to be unable to grow. Spinach has strong growth capacity, so we should increase the nitrogen fertilizer content in the soil to promote the growth of spinach.
The above four points are a brief introduction to the growing environment requirements for spinach cultivation. The prerequisite for growing spinach is to consider these factors well. See whether the cultivation area is suitable for spinach cultivation. You cannot choose blindly, otherwise all your efforts will be in vain, and you will be the only one who suffers.
