How To Improve The Output Of Greenhouse Vegetables

1.Water It Properly

Keeping adequate water is an important factor to ensure the normal growth of vegetables. Choosing a proper time for water and reasonable water amount is an important measure to improve the yield of vegetables, especially in winter. Because the temperature in the greenhouse is lower in winter, the water absorption and evaporation are slower, which is easy to cause adverse effects on the moisture content of the air in the greenhouse and the growth of vegetables. The following points should be paid attention to: first, the watering time should be selected when the temperature is higher, usually after 11:00 a.m. of the day and before 2:00 p.m. During this period, the temperature inside the vegetable greenhouse is higher, which will not cause the occurrence of frost damage. It is also possible to choose water deep in the ground at higher temperatures for irrigation. Pay attention to observe and measure the temperature throughout the shed. Generally, the temperature is a little higher on the sunny side. Water more, and water less in the colder areas. In consideration of the influence of weather, water more on sunny days and less on rainy days is due to high air humidity and low pressure, which is not conducive to water absorption and easy to cause frostbite. The best approach is to use drip irrigation. Not only can achieve the goal of water conservation but also can reduce the humidity in the greenhouse environment to keep dry, conducive to the growth of vegetables and water absorption.

2. Reasonable Fertilization

The right amount of organic elements is also necessary for the growth of vegetables. To improve the yield of the greenhouse, organic base fertilizer should be selected as the first choice. Organic base fertilizer can not only improve the content of soil microelements, but also promote the reproduction of beneficial microflora in the soil, change soil structure, and enhance the storage and supply of organic fertilizer and water by soil substrates. When fertilizing, it is best to pay attention to the principle of a few times, to leave a certain amount of time for vegetables to absorb fertilizer.

3. Reasonable Ventilation

In winter, though the temperature is low, ventilation is unavoidable. Reasonable ventilation is to improve the fresh air in the greenhouse, reduce the carbon dioxide content, and reasonable transmission of light, so that the vegetables have a great degree of photosynthesis, prevent the occurrence of diseases such as yellow, weak light disease, adverse to the growth of vegetables


It is well known that light determines the growth rate of this vegetable. However, in winter, due to the influence of climate, the time of light is short, the days are short and the nights are long.At this time, it is necessary to choose some expected lights to the vegetables such as LED grow lights. Aokairuisi has been engaged in the production of LED grow lights for more than ten years, and the product quality is widely popular by customers.

So when we grow vegetables in winter, we need to pay attention to many aspects.
