Why can’t cultivated leeks see light? What will happen if you see the light?

Chives can survive without exposure to light because the roots and stems store more organic matter, which allows it to consume its own nutrients during its growth. At the same time, nutrients in the soil can also Meet its growth needs so it can survive without light.

1. Generally, solar greenhouses, plastic greenhouses, large warehouses, and spacious houses can be used for shading in places where chives are planted.

Method:

1. Black plastic film can be used outside solar greenhouses and plastic greenhouses, and opaque non-woven fabric can be added inside for insulation;

2. Choose good quality Varieties: According to their early and late attributes, there are early maturing varieties, medium maturing varieties and late maturing varieties;

3. Soil selection: It is better to choose a soil with deep soil layer, high organic matter content, loose and breathable, water and fertilizer retention, Sandy loam soil that can be irrigated and drained;

4. Land preparation: Before planting, the soil must be plowed deeply to facilitate root development. It is better to plow the soil deeply to 25-30 cm. After deep plowing, the soil is exposed to the sun for 3-5 days. The large pieces of soil are broken into pieces and the land is carefully prepared to make borders;

5. Choose a suitable cultivation method: leeks are grown every year Sowing and planting can be done in both spring and autumn, with spring being the best time, from mid-March to mid-April. Autumn is from late September to early October;

6. Watering management: Spring sown leek seedlings must be watered according to weather conditions after sowing. When the weather is dry, water once a day in the morning and evening to keep them moist and allow the seeds to germinate. Fast and early emergence.

2. What should you pay attention to when planting leek flowers?

It is understood that the cultivation of leek flowers requires a cool and humid climate and fertile soil. Before sowing, you need to apply enough base fertilizer, scatter the seeds in the trench, cover them with a thin layer of soil, then water them once, and then water them a second time when the ground becomes dry and wet to keep the soil moist. In addition, just apply enough fertilizer after harvesting to ensure nutrient supply.

3. How can leek perform photosynthesis without chlorophyll

Leek grows in a lightless environment. It does not receive light and cannot perform photosynthesis. Key points for planting leeks: Use the roots of ordinary leeks to grow in the open field. After repeated frosts in the later period, the nutrients will return to the roots. Then, at the appropriate time, move them into protective facilities such as leek trenches and sunny borders. Finally, use leeks under low light conditions. The nutrients stored in the roots create fresh leeks.
