Introduction of Chinese cabbage cultivation techniques;
1, tank container selection
Pots, discarded pots and wooden boxes can all be used to cultivate expensive vegetables. Rectangular wooden cases are the best. The length and width of the wooden box are not limited, and the height is 15 cm, which can hold 12- 13 cm thick soil layer. No matter what container, there should be holes in the bottom, and excess water can seep out of the basin (box) after watering. The size of the wooden box should be based on portability and can be moved indoors in winter.
2. Soil and base fertilizer
Choose sandy soil with good water permeability, take 20- 100 g of decomposed livestock manure and bean cakes from each basin (box) and mix them evenly into the soil as base fertilizer, and then put them into containers.
3. Planting density
The plant spacing is 4×4 cm.
4. Placement
After transplanting 1 week, put it in a semi-shady place, and move it to the leeward and sunny place after delaying the seedlings.
water
Be timely and appropriate. Do "see dry and wet, don't do it, pour it through." "Seeing dry" refers to the situation that the soil water content is low, and the method of knocking on the basin to listen to the sound is generally adopted; The sound is crisp and the soil water content is low, which is "dry"; The sound is heavy and muddy, and the soil contains a lot of water and is "wet". It can also be used to observe the color and properties of leaves of Sedum alfredii (or grass in a pot) to determine the wet and dry conditions of the soil.
You can't water half of it, otherwise the top is wet and the bottom is dry, and you can't water it when the soil water content is high, so that the soil water content is saturated and the air is lacking. In both cases, the leaves are easy to turn yellow, leading to the death of Feicai.
