How to grow autumn napa cabbage? Planting time and management methods for autumn napa cabbage
1. Planting Time
Planting napa cabbage is generally done from July to August. There is a rural saying that describes it this way: radishes in the first fu, vegetables in the second fu. This means that the fu days period is the most suitable time for planting napa cabbage. The South has a longer warm period, so the time can be postponed a bit.
2. Planting Methods
1. Choose good seeds
Napa cabbage is a seasonal vegetable, mainly divided into three seasonal varieties: spring, summer and autumn. Different seasons correspond to different seeds, so you must choose well. Do not mix them up
2. Soil preparation
From July to August, there is generally a lot of rain in most places, and this is a good time to fertilize. Apply different fertilizers according to your own situation. If you are growing it for your own consumption, you can increase the amount of farmyard manure to improve the quality of the napa cabbage. After spreading the fertilizer, prepare the soil, taking care to break up the soil well and avoid large clods.
3. Broadcast sowing seeds
For small plots, you can directly broadcast the seeds, taking care to spread them evenly. After sowing, you can cover with a thin layer of soil. To maintain soil moisture, you can scatter some crushed leaves or chopped straw. Then you can just wait quietly for the seedlings to emerge.
3. Management
1. Reasonable fertilization
Applying fertilizer
During the growing period, napa cabbage seedlings need enough nutrients to sustain growth, so we can use about 4 jin of ammonium nitrate and spread it directly into the holes where the napa cabbage will be planted before sowing. Remember to mix the soil in the holes evenly with the ammonium nitrate, and then proceed with planting.
During the rosette stage, apply a top dressing once, mainly nitrogen fertilizer supplemented by potassium fertilizer. During the heading stage, also apply top dressing, mainly potassium fertilizer supplemented by nitrogen fertilizer, to help the napa cabbage expand. The above top dressings can be applied by flushing with irrigation water.
2. Pest and disease prevention
Napa cabbage is susceptible to aphids and noctuid pests, so timely control is needed, and low-toxicity pesticides should be sprayed as much as possible.
3. Weeding
In addition, weed in a timely manner to avoid competition for nutrients, which can affect the growth of the napa cabbage.
