What's the difference between leek and leek?

Leek yellow is the product of Chinese chive yellowed by softening cultivation. In fact, it is very easy to grow leek. Sowing and early management are no different from leeks, but when producing leek, the green seedlings on the ground will be cut off, and when the new leaves grow to about 15 cm, thick straw mats and shading cloth will be used to block the light, and the regeneration will last about 2 weeks. You can get yellow and tender leeks.

Therefore, the difference between green leek and yellow-white leek lies in whether it is exposed to light-if there is enough light, it will grow into green, strong-smelling, hard-tasting leek, and if there is not enough light, it will grow into yellow, light-smelling, soft-tasting leek.

Second, how to grow leek?

1. Leek root culture

The variety Pingjiu No. 2 with thick, broad and heat-resistant leaves was sown and raised seedlings from early March to early April. Soil preparation, fertilization, bed and soil moisture conservation were carried out before sowing, and plastic film or straw was covered after sowing to increase temperature and preserve soil moisture, and seedlings could emerge after 20 days. Generally, 4 kilograms of seed is used for every 667m2 seedbed, and the ratio of seedbed to field area is 1:5. Control weeds and underground pests in time after sowing. The transplanting time in the field is from late June to mid-July, and the best transplanting time is 3-5 days after the Summer Solstice.

Before transplanting, 3000 kg of high quality organic fertilizer, 30 kg of diammonium phosphate and 20 kg of urea were applied for ploughing and soil preparation. According to the row spacing of 25 cm and hole spacing of 4 cm, there were 3 plants in each hole.

Strengthen field management in time after transplanting and apply 25kg urea per 667 square meters after 20-30 days. During the whole growing period, we should also pay attention to weeding and controlling leek maggots.

two。 Construction of leek yellow cellar

The leek cellar is chosen in the leeward to the sun, the terrain is high and dry. The cellar is 4 inches 5 meters long, 2.5 meters wide and 75 meters deep. The cellar is flattened vertically, and each cellar can row 334 square meters of leek roots in the field. After digging the cellar, the bottom of the cellar is covered with a layer of sand 20 centimeters thick to prevent stagnant water from rotting the roots. Put a cement stick or wooden stick at the top of the pit every 50 cm, put straw on the rod, and put the heat made from crushed wheat straw and other mixed with livestock manure on the straw. The thickness is 20-30 cm, which provides heat for the growth of leek. Finally, the top of the pit is flattened with mud. The cellar door is left in the middle or side of the cellar, with a size of 50 cm square.

3. The planing of the leek root

The starting time of leek root is generally from the first ten days of November to the first ten days of December, and the specific starting time is determined according to the listing time of leek planting. When ploughing leek roots, try to hurt the roots and bulbs as little as possible, shake the soil after planing, cut off the excessively long fibrous roots, and tie them into a handful every 20 to 30 trees, ready to enter the cellar.

4. Go into the cellar

Before entering the cellar, use 100 kg of fine clay and 200 kg of water to make mud. Soak the leek roots in the mud for 2 minutes. Remove and drain the roots into the cellar immediately. Row roots from the four corners of the cellar, discharge to the cellar door, and leave a good aisle. Row leek roots should be in close contact with the soil, so that the upper and lower solid (www.nczfj.com/), each close to each other. Finally, seal the cellar door, insert the thin bamboo pole with the middle section into the cellar, use the thread to put the thermometer into the cellar through the thin bamboo pole, and observe the temperature change in the cellar.

5. Cellar management

The management of temperature and humidity in the cellar is the key to the success or failure of leek planting. Humidity should be kept free of water droplets on the leaves to prevent leek rot. The temperature of the first crop was controlled at 10: 18 ℃, the second crop at 18: 20 ℃, and the third crop at 20: 22 ℃. In the whole process of growth, the temperature should be kept relatively stable, not suddenly high or low, and water should be watered in time to prevent chives from burning the cellar.
