How does spring cabbage grow properly? Four Key Points for Improving the Survival Rate of Spring Cabbage Seedlings
Many vegetables like to eat, and cabbage is also popular with people. Cabbage is one of the spring vegetable cultivation, and it is a vegetable variety with a large cultivation area. Why is it cultivated widely? This is because sugarcane cultivation has less investment, labor saving, high yield, and can be cultivated everywhere. Now it's almost the spring season of spring cabbage, and the following is a brief introduction to the technical points of cabbage seedlings.
Key points of spring cabbage seedling technology
1, choose the best species
In the spring open field planting, you can use varieties such as Zhonggan 15, Zhonggan 21, etc., which have early maturity, high yield and strong disease resistance. In early spring cold shed cultivation, you can use varieties such as selected 8398 and Chunqiang, which have strong cold resistance and strong disease resistance.
2, prepare the seedbed
In the nursery bed soil, the soil should be fertile, and the Shangyu has not planted the garden soil of cabbage, cabbage, radish and other vegetables. Each seedling bed covering an area of ​​0.1 mu needs to be applied with 500 kg of high-quality ring fertilizer and 5 kg of ternary compound fertilizer. The organic and inorganic fertilizers are evenly spread and then turned deep and flat. If you use Yangshuo seedlings, you should do a good job of impotence, cover the plastic film on the surface for 15 days, and wait until the ground temperature rises before planting.
3, timely seeding
The best sowing time for the early spring cold shed cabbage and the cabbage cabbage in North China is between late December and mid-January. It is generally used in solar greenhouse or improved impotence seedlings, which can ensure the growth of seed. Generally, the planting density of early-maturing varieties is about 4,500, and the medium-early-maturing varieties are 3,500-4,000, and the amount of acres used is about 50 grams.
Before sowing, the seeds generally do not need to be germinated, and the seeds can be broadcast live. The seedlings should be poured with water at the bottom of the seedlings. The seeds should be evenly distributed. After sowing, the fine soil should be covered to protect the nursery from cracking.
4, seedbed management
Before the emergence of the seedlings, the temperature of the greenhouse or impotence should be kept at 15 °C ~ 25 °C, and the seedlings can be emerged after five days of basic sowing. After emergence, we should pay attention to the timely release of the wind, and the temperature is best maintained at 10 °C ~ 20 °C. If the seedlings grow too densely, then we have to carry out the seedlings, which can prevent the seedlings from growing.
When the seedlings grow to 3 true leaves (about mid-February), the seedlings must be transplanted again, and the seedlings can be transplanted into the nutrient bowl. Remember that the temperature of the seedbed is generally between 8 °C and 20 °C. In March, the seedlings must be re-smelted at a low temperature before planting, and the amount of air is gradually increased. The minimum temperature of the seedbed can be gradually reduced to about 5 °C, so that it can adapt to the cultivation environment of the field, which is conducive to rapid seedling raising and improvement. Survival rate.
The above is the technical point of spring cabbage seedlings. Would you consider cultivating cabbage? When we grow cabbage, we must keep in mind the points introduced in the above-mentioned small and medium-sized series. I believe that it will help you to grow high-yield cabbage. Do you have any high opinions on the management of cabbage planting? Welcome to share the message.
