Every year, the two volts and three volts in summer are very suitable for planting cabbage. Because cabbage is a vegetable that many farmers often eat, it is relatively simple to grow and store. If you want to grow high-quality cabbage, you should pay attention to what kind of cabbage. What about planting management skills? Let's go check it out!
First, the choice of varieties and plots
Introduced by professional growers, summer cabbage, heat-resistant, early maturing of the ball, short growth period, and strong varieties of anti-cabbage virus are better. In this way, the leaf area of ​​the cabbage is large and thin, the root system is shallow, the summer temperature is high, and the transpiration is large; therefore, the cabbage has strict requirements on water and soil. Therefore, it is suitable for planting in areas where the soil is loose and fertile, and irrigation and drainage are convenient.
It is generally recommended to plant high ridges, which not only facilitates irrigation and drainage, but also enhances the permeability of the field and reduces the occurrence of diseases. Such as soft rot. First of all, the field is applied to the base fertilizer, organic fertilizer is about 5,000 kg/mu, compound fertilizer is about 50 kg/mu, and the soil is deep into the soil together, and the soil is even and meticulous. Then ridges, the line spacing is about 50 cm, and the plant spacing is about 20 cm (depending on the variety description).
Second, sowing and management
Cabbage seedlings have a wide adaptability to weather temperature, and when the product organs are formed, they prefer lower temperatures (15-22). Cabbage likes the mildness of the early stage and the cold growth environment in the later stage. That is to say, in the time period of the hot tail cold head, it can be sown. Of course, we should also consider the characteristics of the variety, resistance, etc.; I want to see the maturity of the cabbage as early as possible, and generally choose the early broadcast.
Cabbage can be used for sowing or ditching (no need to transplant), watering is not enough to make water, and after planting, cover the soil and compact it properly. After the sowing, the field should be kept moist, but not water. Generally, the cabbage is 3-5 days old and it is easy to germinate and emerge.
Third, check the seedlings to fill the gap
After the seedlings, it is recommended to have a time seedling, which is more conducive to the normal growth of cabbage, carried out in 2 leaves. When the seedlings are inspected, it is necessary to check the lack of seedlings and weak seedlings, remove the sick, weak, and dense seedlings, and replant the lacking seedlings. When 5-6 leaves are used, the seedlings can be fixed, and the weeds in the field are removed.
Fourth, fertilizer management
Generally, in the case of sufficient fertilizer in the field, it is not necessary to topdress before the cabbage ball-forming period; if the field is barren, it will be topdressed in 7-8 leaves, the weather is hotter in the early stage, and the manure is obeyed. When it is as thin as possible, that is, the concentration is lower; during the rosette period, the amount and concentration of human excrement should be increased to meet the nutrient requirements of cabbage; during the ball-forming period, the demand for potassium in cabbage is increased, not only to apply nitrogen fertilizer, It is also necessary to increase the potash fertilizer, which can be mixed with urea and compound fertilizer, watering after topdressing, meeting the characteristics of large water requirement during the heading period of Chinese cabbage, and also promoting the rapid absorption and utilization of nutrients; during the ball-forming period, sufficient water can also prevent dried cabbage. The heartburn occurs, but there is no water in the field. Try not to flood the water to prevent disease.
Watering should be reduced or stopped before harvest to ensure quality and storage and transportation; if it is rainy, it is necessary to drain water in time.
V. Pest Control
In summer, the temperature is high and the humidity is high, and summer cabbage is prone to soft rot and dry heart disease. This is the main disease affecting the yield and quality of Chinese cabbage. There are certain plans during planting, strictly guard against water accumulation in the field, and dense planting density, reduce humidity; provide better conditions for the growth of cabbage, pay attention to the lyrics in the field during the balling period, and have a high probability of dry and heartburn. Excessive watering and humidity are prone to soft rot. Therefore, it is necessary to control the water consumption during the ball-forming period, so that it is better to moisten without water. In the early stage of the ball, it is necessary to properly supplement the cabbage with calcium, which is also an important management measure to reduce the dry heart.
In summary, farmers should pay attention to the cultivation and management techniques of Chinese cabbage, so that the quality and output of cabbage are constantly rising, and the transformation of economic benefits is realized. I hope this article can help everyone.
